Please note that you cannot bring your Microsoft Windows Operating System (i.e. Windows 2016, Windows 2012 etc) license to Zettagrid as this will violate the Microsoft Licence Agreement (EULA). Zettagrid can rent you a monthly licence for this purpose.

 

Can I rent other Microsoft licenses?

Yes, Zettagrid has access to full range of Microsoft SPLA licensed products. Please contact sales@zettagrid.id if you would like to rent one of the following licenses on monthly basis.

  • Microsoft Dynamics
  • Microsoft Exchange
  • Microsoft Forefront
  • Microsoft Office
  • Microsoft Project Server
  • Microsoft Project
  • Microsoft Search Server
  • Microsoft Sharepoint Server
  • Microsoft SQL Server
  • Microsoft System Center
  • Microsoft Visual Studio
Do you offer cPanel?

At the moment we only offer Microsoft software as additional software options to be installed. However you can purchase your own cPanel, Plesk or other management control panel license and install this on your Zettagrid Server.

How are Processors, Cores and GHz related? How do they affect Licensing?

At Zettagrid for licensing purposes we define our Processors (or CPU’s) in terms of capacity or GHz.  The number of cores is unrelated to Ghz or Processors and has no effect on Microsoft licensing.  For licensing purposes a CPU is defined as 2GHz of capacity.  If you have up to 2GHz then and elect to license under a processor model you will require a single Processor license.  If you have 2.1 GHz, 2.4 GHz etc then for licensing purposes you require TWO processor licenses.  At Zettagrid we are able to cap the maximum amount of processor licenses required at TWO.  If for example you have a total of 10GHz CPU in your VM, rather than paying for FIVE processor licenses, due to our cap you only require TWO licenses.  If you have 10GHz and decide to split this into 2 VM’s of 5GHz each you require FOUR processor licenses in total rather than TWO.  This is because processor licensing is applied on a per VM basis.

What is a processor license?

A processor is a way of licensing Microsoft software on a subscription basis within Zettagrid.  A processor license allows an unlimited number users access to the Microsoft software.  Processor licenses are usually more expensive than a Subscriber Access License (SAL), however they become cost-effective with increasing number of users.  Unlike a SAL which can be used to access more than one instance (or VM) of the software, a processor license has a direct relation to the number of VM’s you have.  If you have ONE VM then you need ONE set of processor licenses, if you have TWO VM’s then you must purchases TWO sets of processor license and so on.  Zettagrid cap the number of processor licenses per VM at TWO, regardless of the amount of cores or Ghz in your VM.  See an explanation of cores vs processors vs Ghz elsewhere in the FAQ.

What is a Subscriber Access License (SAL)?

A Subscriber Access License (SAL) is one of the options for licensing Microsoft software under a subscription model.  A SAL is required for each unique USER or DEVICE accessing a Microsoft product.  A SAL is not a concurrent license and hence cannot be shared amongst multiple users or devices.  Multiple users can access through a single device, or multiple devices can be used by a single user, however you cannot aggregate concurrent users through a single device – individual user SALS are required.  Nonconcurrent users through a single device is allowed.

S.A.L Usage

A SAL can be used to access any number of instances of the Microsoft software.  For example if you have a Windows Server and want remote access for ten users you must purchase 10 SAL’s.  If you then purchase a second VM with a second copy of Windows and require access for the same ten users you do not have to purchase additional SAL’s.  The existing SAL’s are valid for as many Windows Servers as you may wish to provision, thus additional Servers can be had for essentially the incremental cost of a VM without incurring additional server license fees.

Can I bring my existing software licenses to the cloud?

Yes, You can use your existing Microsoft Enterprise Mobility to use your existing licenses on Zettagrid. Read more about Licence Mobility.

What software is available on Zettagrid?

We have a full range of Microsoft software. We also offer monthly licencing for Vyatta, Trend, Citrix and F5.

VIRTUAL SERVER  VIRTUAL DATA CENTREVIEW SOFTWARE CATALOG

 

What is the difference between a SAL and processor license?

Microsoft products can be licensed in two ways -by Subscriber Access License (SAL) or per processor (Proc).  Some products are only licensed one or the other whilst other products can be licensed either.  The essential difference is that a processor license allows unlimited users whilst a SAL is required for each unique user or device accessing the software. For products that allow either licensing model determine the cost under both models and opt for the cheaper one.  Generally the larger the number of users the more economical a processor license becomes.  Please see the individual SAL and processor FAQs for more detail.

How do I transfer files to my VM?

You can use standard file transfer protocols once you have opened these ports on your Virtual Server. For Windows you can enable local drive mapping or WebDAV or create and FTP server. For Linux you could enable FTP/SFTP.

If you would like to perform an initial “seed” of a large volume of data please contact support@zettagrid.id to discuss alternative population methods.

What is the Default Password for Zettagrid Catalog VMs and Can I change my VM password once my VM is Built or Deployed?

The default password for all Zettagrid Templated VMs is specified under the Security Tab of the Virtual Datacenter Service. It’s strongly suggested that the default password is changed once a VM Template has been deployed.

Can local DVD be copied to the virtual server?

You can mount an ISO or DVD to your virtual server using our vSphere administration client but this may be quite slow over the internet. We recommend setting up your own FTP/SFTP service to transfer the files.

ioSTOR (2)

Can I Mix Storage Tiers in a VDC?

Yes, however, individual VMs are limited to one storage tier at a time.

Can I Change Tiers at any Time without Downtime?

Yes, you can migrate between storage tiers at any time without downtime, however there are a few caveats:

  • Migration between ioSTOR-250 (and higher) and any other tier will become effective immediately.
  • Migration from ioSTOR-100 (Archive Tier) to any other tier will take much longer due to the speed of the archive storage. Your VM storage performance may be affected during the migration process so schedule it out of a peak period.

Veeam Cloud Connect (3)

Seeding Cloud Connect for Veeam Backup Jobs

This FAQ provides the steps to manually seed a Backup Copy job with Cloud Connect for Veeam. Seeding a Backup Copy Job with Zettagrid will reduce the initial time and bandwidth required to commence using Cloud Connect. If you want to seed a Backup Copy job you will need to do the following:

  1. Send a Seed Request to support@zettagrid.com and take note of the Ticket Number (e.g. INC1234567).
  2. Create a new Backup Copy Job/Backup Job.
    • Backup Job – Add VMs from vCenter
    • Backup Copy Job – Add VMs from an existing Backup Job or from Backups
  3. For the Target Repository, initially select a Local Repository and let the job run to seed the data.
  4. Disable the Backup Copy Job/Backup Job once the first run has completed.
  5. Copy the folder where the job files are contained from the Local Repository to an External Storage Device (USB/NAS).
  6. Label the device and package with the Ticket Number (e.g. INC1234567).
  7. Send the Storage Device to Zettagrid (shipping address will be provided in your ticket).
  8. Wait for confirmation from the ticket that the import has been completed.
  9. Rescan the Cloud Repository.
  10. Modify the Backup Copy Job/Backup Job to point the Target Repository at the Cloud Connect Repository. Then click “Map Backup” and select the correct job.
  11. Enable the Backup Copy Job and resume the stream.

Bandwidth Requirements and Sizing for Cloud Connect for Veeam Backup Jobs

How much Bandwidth is needed for Cloud Connect for Veeam Jobs and

While this does vary depending on the size of you backup job and your connection to the Internet and its use (dedicated or otherwise).

It’s Recommended that you have 1Mb Upload Speed for every 300GB or data.

How do I Size the Cloud Storage?

To size your Cloud Connect Offsite Repository you should take into consideration the size of the backup job(s) on your local Veeam Server. There is a one to one relationship in terms of what the size of your backup is locally as to what is stored offsite.

How do vCPUs work in Zettagrid?

What is a vCPU?

A vCPU is a virtual CPU and is an encapsulation of many underlying physical blade host processors presented via VMware to a single VM as its local processor.

Since a vCPU is based on the underlying host CPU the actual GHz amount will be a one to one mapping from its physical counterpart.

What is a vCPU in Zettagrid?

2.5GHz

Zettagrid create clusters which are all of the same CPU type so as to not mix CPU types and lose any of the available CPU instruction sets as anything in the same cluster will remove CPU instructions down to a common base level among all hosts in that cluster.
Previously the GHz has been 2.67GHz and 2.3GHz, at the moment and for at least the next 12 months the current CPU spec in terms of GHz is 2.5GHz per vCPU.

Does higher GHz per vCPU mean it’s better?

No, whilst there is a correlation between the two it isn’t really a good indication of value for money or being on a better host if the underlying CPU is 2.6GHz rather than 2.5GHz.

As we upgrade the environments they will often get different CPU types and GHz amounts. At all times the introduction of a new CPU type means a better performing VM as it is a newer generation with a higher instruction set.

It is quite conceivable that in future the next GHz amount may in fact reduce per vCPU. This will actually mean that for the same price per month the customer is getting more value as the amount they have purchased can be utilised for more concurrent vCPU.

How do you sell CPU resources?

We sell CPU resources as a total of GHz consumed at any one point in time in the environment.

It is not an allocated model it is a concurrent consumed model or a high water mark. This means that customers can utilise very large amounts of overprovisioning if so desired but this might mean that in peak times when many of your VMs are running high CPU workloads you will be limited in terms of available CPU resources. In the event of this the VMs will go into a CPU Wait state for available resources when other VMs in your own environment are not using them.

Scenarios

  1. Customer has 100 VMs all with 2 vCPUs assigned. The customer is paying for 500GHz. In this scenario all VMs will be able to utilise all the resources that have been paid for as even if every VM is running both CPUs at 100% the total will only be 500GHz which is what has been assigned to the customers Virtual Data Centre. There is no conceivable event where any VM does not have access to its resources.
  2. Customer has 8 VMs all with 1 vCPU assigned, 6 powered on and 2 powered off. The customer is paying for 16GHz. In this scenario the 6 powered on VM are working fine performance wise. The customer has powered on an additional 2 VMs and now their users are complaining of performance issues. With the 8 VMs powered on the requirements could burst up to 20GHz but the customer is only paying for 16GHz so the customer would need to either be aware that performance may be an issue, power off the additional 2 VMs or increase the allocated resources in the environment to 20GHz.
  3. Customer has 100 VMs all with 1 vCPUs assigned. The customer is paying for 30GHz. In this scenario the customer is obviously drastically under allocating CPU resources for their VDC as the provisioned amount would be 250GHz. In day to day usage of the VMs they are generally only 10% utilised in terms of CPU. 10% of a single vCPU is .25GHz and for the 100 VMs this is 25GHz in total day to day. In this scenario whilst the customer is not paying for nearly enough CPU it is not constrained in normal activities as they are still under the 30GHz total that has been allocated. A warning in this scenario though, if any VMs start doing work more than the average then there may be periods where the total GHz used is over the 30GHz so it will be resource constrained when this occurs and potential for users to create service desk tickets complaining of performance problems.
  4. Customer has 100VMs with a mixture of 1-4 vCPUs assigned. The customer has allocated 200 GHz to the Virtual Data Centre. Generally in the environment the VMs day to day run at 30% which would have a total resource requirement in GHz terms of 260GHz. In this scenario the VMs will constantly be resource constrained by our systems as there is not enough resources provided so it is expected that the VMs will run slower than they should be in normal circumstances as they are continually in a CPU Wait state.

So how much should I buy?

This is a hard question to answer as it is different for every customer. If you want to ensure that your VMs always have the CPU resources that they require then purchase 2.5 x the total number of vCPUs assigned to VMs per Virtual Data Centre.

If you think your VMs often don’t need all their CPU power then you can under allocate by 50-80% and see how the performance goes day to day whilst making sure that you capture all use cases (like the end of month reports that run etc). If you find that users are feeling the VMs underperforming then increase the resources until you find a happy medium of price/performance.

If cost is the driving force entirely then reduce the amount of GHz allocated to the VDC drastically and simply put up with the artificial limits that are placed on each VM and be aware that the VMs will be considerably crippled.

Isnt it easier to just sell vCPUs?

Yes, it most definitely would but we prefer to give customers the final say in how much overprovisioning they wish to have in their own environment so that there is more granularity and control over how their VDC performs.

You may have a few Virtual Data Centres and would like to have the production VDC fully allocated in terms of vCPU so it is never constrained but also have a test VDC in which it really doesn’t matter if it suffers from CPU Wait times as performance is of no concern. In this scenario the test VDC may only have 25% of the required CPU resources and is a great way to save money rather than wasting it on CPU where it isn’t valued.

 

Memory Hot Add Limitations for Linux 64-bit Virtual Machines

When trying to hot add memory to a Linux 64-bit guest operating systems, you cannot increase the memory to more than 3GB. You would see the following error:

“An invalid memory size has been specified. The maximum hot-add memory limit is 3,072 MB.”

These conditions apply while hot adding memory to virtual machines with Linux 64-bit guest operating systems:

  • If the powered-on virtual machine has less than 3GB of memory, you cannot hot add memory in excess of 3GB.
  • If the virtual machine has 1GB of memory, you can add 2GB.
  • If the virtual machine has 2GB of memory, you can add 1GB.
  • If the virtual machine has 3444MB of memory, you can add 128MB.
  • If the powered-on virtual machine has exactly 3GB memory, you cannot hot add any memory.

For more information, see this VMware KB article.

Storage Allocation and VM Overheads

The storage numbers are always calculated the same way for Virtual Datacenters:

Storage Used = Total allocated disk space of VMs deployed in Org VDC + Total memory of VMs deployed* in Org VDC (to account for VM swap usage) + Maximum possible existing snapshot size

Storage allocated = Org VDC storage allocation

Example 1: If you have 1 VM with 1 GB RAM and 10 GB disk the storage usage will be: 10 GB (disk) + 1  GB (VM swap) = 11 GB.

Example 2: If you have 1 VM with 1 GB RAM and 10 GB disk and create a snapshot (including memory), the storage usage will be: 10 GB (disk) + 1  GB (VM swap) + 10 GB (maximum disk snapshot size) + 1 GB (memory snapshot size) = 22 GB.

* Virtualisation Platforms stores VM Memory as files on storage to increase resiliency  in HA scenarios and during periods of high usage.

Can I resell/wholesale Zettagrid?

Yes, channel partners can resell and wholesale Zettagrid.

Can I manage multiple Datacenters from the one login?

Yes, when we create your Zettagrid Datacenter we actually create you a new “Organisation”. This Organisation can manage multiple Cloud Datacenters.

Typically, Zettagrid partners with multiple customers create individual Cloud Datacenters for each customer to simplify networking and billing for each customer.

I’m an IT Integrator, will my end customers know that I’m using Zettagrid?

If you wholesale Zettagrid services (where you bill your customers), then your customers will never know that you are using Zettagrid. You can claim it as “your cloud”. You can even change the reverse DNS!

If you resell Zettagrid (where we bill the end customer), customers will see invoices and emails from Zettagrid.

Are your servers located in Indonesia?

Yes, all our infrastructure including servers, storage and networking is hosted in Indonesia. This ensures that all information stored is governed by Indonesian government legislation including Privacy, Copyright and Company laws.

Please see our Data Centre page for specific locations, Availability Zones for general geographic spread and Our Network for communications links.

 

Do you offer burstable limits on RAM and CPU?

No. To set a performance benchmark we only allocate the resources that are purchased.

Providing “burstable” resources sets a false expectation of performance. When the cloud environment gets busy (in a burstable environment) your server is often not allocated additional resources thus making you feel that your server is performing slower than normal. Zettagrid does not do this. We only allocate those resources that you purchase and guarantee that these will be available.

How are VMs protected?

Each individual VM (or group of VMs) is protected within its own security zone. We utilise both network and VMware based security measures to encapsulate all VM traffic and prevent activities like:

  • IP Address Hijacking
  • MAC Address Spoofing
  • Broadcast Traffic Flooding

If you would like more information on our security measures please read our Technology Security summary or contact one of our sales staff who will be able facilitate answers to more specific queries or security scenarios.

Do Zettagrid staff have access to my VM operating system

No. Staff do not have any permissions and cannot logon to your VM. You control the password to log into your VM.

What is the minimum contract length of the service?

All contracts are “month-to-month” (30 days technically). You can cancel at any time. If you cancel prior to the end of the 30 day period you will not be eligible for a refund or credit for the unused portion of your service. We do offer discounts for long term contracts.

Can I purchase additional IP addresses?

Yes, additional IPv4 addresses can be purchased individually. Justification is required with each request.

Note: that each Virtual Server and Virtual Datacenter is allocated one static IPv4 address.

Can I change the reverse DNS on my IP Address?

Yes. Please email support@zettagrid.id detailing the PTR record you want created and this will be completed at no cost.

Do you backup the VMs?

Please refer to our Backup page.

 

 

Can I restore/rebuild my VM from a fresh machine if I break my VM?

Yes. You can do this at any time via My Account -> My Servers. Your virtual server name and IP address are kept but all other information is destroyed during the rebuild. We recommend backing up your files prior to doing a rebuild.

Will Zettagrid restore my VM from backup if I break the VM?

No, not unless you have purchased a Disaster Recovery product like VM Backup.

You will need to rebuild the virtual server from My Account -> Servers and then restore your data onto the servers. Zettagrid provides an unmanaged service. Managed server options are not available at this time.

What payment methods are accepted?

We accept:

  • Credit Card
  • Virtual Account
  • Bank Transfer
Is the internet quota allocated to my VM in both directions?

Yes. They your uploads and downloads combined in your internet quota.

What does excess data over quota cost?

Excess data costs IDR 900 per GB (exc PPn). This is automatically charged to your credit card or invoice monthly in arrears.

You can resize your Internet data quota (or any other attribute) at any time by logging into My Account > View Service > Click Resize > (Drag the slider).

Who is responsible for patching my cloud servers?

You are responsible to patch your servers. Zettagrid does not currently provide a service to manage your servers for you. We recommend you engage an IT professional to maintain the security of your servers should you require assistance in this area.

Is my VM guaranteed the resources detailed in the plan?

Yes. We guarantee the resources allocated to you are available to your Virtual Server or Virtual Datacenter.

I’m outside of Indonesia, can I use Zettagrid?

Yes, although when you create an account it will be first reviewed first by a Zettagrid team member before you will be permitted to purchase services online. The purchase price is in Indonesian Rupiah (IDR) and will be converted by your credit card provider.

 

Virtual Server versus Web Hosting

Web hosting is certainly not an easy proposition, especially when a variety of options are available. However, like most things, there are some prominent trade offs. For instance, dedicated hosting is easily customizable and powerful too, but it is expensive. Additionally, adequate technical knowledge is also needed to be able to manage dedicated servers. Shared hosting, on the other hand, is inexpensive and easy to use; nevertheless, it can provide only a limited number of resources.

What will you do if you have website that is too large for a shared hosting plan, and that does not require extensive resources provided by a dedicated server? Virtual Server (VS) hosting is the most feasible alternative for you. It is an adaptable, economical and scalable hosting solution that has the power to fulfill the needs of any kind of website. It is a perfect option for those sites that have outgrown shared hosting plans, and are yet not ready for dedicated hosting servers. Let’s find out how virtual private server can help you to save your hard-earned money while hosting your business website.

What exactly is a virtual  server?

Also called Virtual Dedicated Server (VDS), a virtual server is basically a methodology of splitting a physical server into segments. Each partition has a full-fledged operating system and can be rebooted independently. Every VS has its own unique IP address and it gets a share of CPU time, RAM and storage of the physical server. VS primarily helps to bridge the gap between shared and dedicated servers. The users are able to configure their portion as per their requirements, and that too at a less cost than dedicated hosting service.

What are the different kinds of VPS hosting plans?

Virtual private server hosting plans can be segregated into three broad categories viz.

  1. Unmanaged VS- In this case, the hosting company provides only hardware and network services. Whilst, as a user you are responsible for dealing with all the software and performance hassles and issues.
  2. Semi-managed VS- Here you are allowed to manage just the custom software, while the hosting company takes care of hardware, standard software and network.
  3. Fully-managed VS- With respect to this kind of VS hosting plan, you literally don’t have to manage anything. The host company looks after all the aspects of VS. It’s the company’s duty to provide you superlative services.

In simple words, VS provides flexibility together with accessibility and complete control. You can not only access the root, but you can also amend server-level software like MySQL, PHP and Apache. Thus, with virtual private server, you get all the benefits of a dedicated server, but in a package that is affordable and manageable.

Burstable RAM and VS

The primary drawback of a shared hosting server is that all the users get only a limited amount of memory. If all of a sudden, the website receives a truckload of traffic, then everything would be blocked due to paucity of resources. The burstable RAM in the VS counteracts the Digg-effect effectively. Burstable RAM is nothing, but a pool of memory that is set aside to handle extraordinary events. Hence, no matter what kind of traffic your site receives, VS hosting plans would never fail.

Dynamic Routing Provides the necessary forwarding information between layer 2 broadcast domains, thereby allowing you to decrease layer 2 broadcast domains and improve network efficiency and scale. NSX extends this intelligence to where the workloads reside for doing East-West routing. This allows more direct virtual machine to virtual machine communication without the costly or timely need to extend hops. At the same time, NSX also provides North-South connectivity, thereby enabling tenants to access public networks.

Can I Upgrade My Existing Basic Edge Service

At this stage there is no automatic upgrade and migration option however this is something that will be introducing in the near future allowing for a one click upgrade and migration from Basic to NSX Advanced. In the mean time you are able to provision a new Virtual Datacenter with NSX Advanced Networking and migrate your vApps and VMs to the new NSX Enabled vOrg Network. Stay tuned for a how-to video on how to achieve this.

Can I Upgrade/Downgrade My NSX Edge Service

At this stage there is no upgrade or downgrade option once the NSX Advanced Networking Service has been provisioned (including moving between a HA and non HA option) however this is something that will be introducing in the near future allowing for a one click operation to move between sizes and HA configurations. Please contact support to request this change in your service.

SecondSite FAQs (10)

What is the minimum amount of VMs needed for SecondSite™?

There is no minimum amount of VMs required for SecondSite™ because it’s scalable.

Whether you’re protecting one VM or 1,000 VMs, it’s the same reliable and affordable solution for small businesses and large enterprises.

The number of VMs you protect does not alter the unit price or the feature set available. That’s why we make it easy and charge per VM, per month, with no lock-in contracts.

What if I use Hyper-V/VMware in my environment?

SecondSite™ works seamlessly with Hyper-V and VMware in your environment.

We can protect either environments, as we will run VMware on our side for you. That means that we will convert your Hyper-V based VMs into VMware formats as they are brought online after a failover.

Can I use SecondSite™ to migrate VMs into Zettagrid cloud?

Yes, you can use SecondSite™ to migrate VMs into Zettagrid’s cloud.

By using SecondSite™ as a migration tool, you can easily fail your VMs over into Zettagrid cloud.

Once you have migrated everything across, you can either cancel your SecondSite™ subscription since there are no lock in contracts, or you can continue using it and have your old production infrastructure as your disaster recovery (DR) site.

 

Why do I get disconnection reports?

Your SecondSite™ subscription was automatically set up between you and Zettagrid using an IPSec VPN.

As this relies entirely on your outbound internet, there may be periods where you do not have the required 5Mbit/s minimum of bandwidth. It is at this point where SecondSite™ may report a disconnection.

SecondSite™ will re-establish the connection as soon as the bandwidth is available again.

If you are experiencing these sorts of disconnection alerts, please refer to our WAN Connectivity page and use the WAN Sizing tool to determine exactly how large the link needs to be for your business.

If you would like us to provide WAN connectivity for you, please contact us on +62 21 2960 7589, +62 811 283 878  or at support@zettagrid.id

What do I do about external DNS/IP addresses?

While SecondSite™ takes care of many things for you, there are a few items that you still need to take care of in your Business Continuity (BC) or Disaster Recovery (DR) planning.

This includes external DNS/IP addresses.

When you have failed over to Zettagrid’s cloud you might have some external websites or IP addresses that may require changing.

With advance planning, you can ensure that all external websites or IP addresses can still be accessed after failover. For each of these you will need to think about which apprach you will take. You may decide to add steps to edit your external DNS records through whomever provides your external DNS in your DR plan. Alternatively, you may choose to introduce global load balancers so that this step is seamless.

There are a number of options available to you and it’s important to select the right approach for you and your business.

 

What firewall ports need to be open?

If you have issues with pairing or during operation, please ensure that you have the following ports open.

Port Description
4007 TCP control communication between your local VRAs to our VRAs through your dedicated ZCC.
4008 TCP communication as above to pass data from your protected virtual machines to our VRAs through your ZCC.
9081 TCP communication between your ZVM and our ZCC.

 

What is a Recovery Point Objective (RPO)?

A Recovery Point Objective (RPO) is the specific point in time that your data can be recovered to.

Lower RPOs mean less potential for data loss. Conversely, higher RPOs mean potentially more data lost in the event of a disaster.

From within Zerto product you are able to set a “target RPO” for each VPG you create. The service profile you choose is an indication of the allowable data loss for the VMs in that VPG.

SecondSite™ powered by Zerto provides incredibly low RPOs of just seconds.

RPO examples

3-10 second RPO

This is the default RPO you will receive with SecondSite™ if you have enough bandwidth available. If you needed to fail over, you will experience only between three and 10 seconds of data lost.

8 hour RPO

If your RPO were to extend out to eight hours, a disaster and failover at 8 pm would mean your data will be as it was at 12 pm lunchtime. You will have lost any data entered into systems/applications in the previous eight hours.

24 hour RPO

If your RPO were to extend out to 24 hours due to insufficient bandwidth, a disaster and failover at 2 pm will mean your data will be as it was the day before at 2 pm. Any data that was entered into your systems or applications in the previous 24 hours will be lost.

 

What is a Recovery Time Objective (RTO)?

A Recovery Time Objective (RTO) is the amount of time it takes from the moment you initiate your disaster recovery (DR) failover to when you are able to use the VMs in the new SecondSite™ environment.

A lower RTO is better because it will typically mean that disruption to operations are minimised, users can get back to work quicker and your websites are back online faster.  Low RTOs means less chance of your customers or other external parties even realising you were down for any period of time.

SecondSite™ stands out by offering incredibly low RTOs.

RTO examples

5-10 minute RTO

This is the default RTO you will receive when using SecondSite™. It means every VM comes online at the same time after a disaster event.

20-30 minute RTO

If you have selected to power some VMs up only after other VMs have successfully powered up, then you can expect an RTO of around 20-30 minutes.

>30 minute RTO

It is possible to inject scripts or wait times within SecondSite™ that can do pretty much anything in your environment. If you add in some scripts or commands which take a long time to process or complete, then your RTO can be greater than 30 minutes.

What is a Service Profile?

When creating Virtual Protection Groups (VPGs), you will need to select a Service Profile for each VPG.

There are four Service Profiles to make it easier to group VMs together based on target RPOs.

Service Profile
Target RPO
Description
Bronze 8 hour This is the default profile and any VM in a VPG with this profile will have a target RPO of 8 hours.
Silver 1 hour Any VM in a VPG in this profile will have a target RPO of 1 hour.
Gold 15 min Any VM in a VPG in this profile will have a target RPO of 15 minutes.
Platinum 5 min Any VM in a VPG in this profile will have a target RPO of 5 minutes.

Bandwidth saturation or contention

In the event of bandwidth saturation or contention, the Service Profiles will be used to determine which VPGs have priority over others.

If a VPG has a more aggressive target RPO than another VPG, then its block changes will be failed over into Zettagrid’s cloud before its lower profiled counterpart.

Lower Service Profiles will failover after higher Service Profiles have successfully failed over.

What is a Virtual Protection Group (VPG)?

A Virtual Protection Group (VPG) is an affinity group of one or more VMs.

They are then grouped together from that point on and exist as a single entity from Zerto’s perspective.

Usually VMs are grouped together based on a need to be kept and dealt with at the same point in time. Examples of this are Domain Controllers or a web front end and its database counterpart.

You may also consider grouping VMs together based on the target RPO, for example grouping all Silver VMs together and all Bronze VMs together.

Generally, the more VPGs you have, the more granular control you will have over the environment and the more flexibility you will have when failing over or testing the product.

You have flexibility when it comes to your VPGs. Changing VPGs based on your changing needs is straightforward and easy.

How do I connect to Zettagrid’s Cloud Connect Service?

Once your service has been ordered and provisioned, click here to follow the initial configuration steps to get your Veeam Backup & Replication console connected to your Zettagrid Cloud Connect zone.

How do I configure Cloud Replication Jobs?

Now that the setup is complete, it’s time to start consuming Zettagrid Cloud Connect replication resources. In Veeam terms, a Cloud Host is the abstracted view of Zettagrid’s replication platform, and seen as a remote virtualised host that can be used as a replication target. in Cloud Connect Replication jobs are configured in the same as standard Veeam Replication jobs with only the target is different. Click here to see how to configure a Cloud Replication Job.

How do I create Failover Plans?

Once all the selected virtual machines have at least one restore point replicated up to Zettagrid, you can use the failover resources to action a full failover. Before a Full Failover can initiated a failover plan must be configured. Click here to view how to create Failover Plans.

How do I view Replica Statuses?

After a replication job targeted at Zettagrid completes, it can take a few minutes for the Veeam Backup & Replication console to retrieve changes from the database and display those changes on the tenant side.  Click here to see how to view Replica Statuses.

How do I test my Failover Plans?

Once a Failover Plan has been created you can now test the validity of the VM replica’s by initiating a Failover Plan test. Click here to view how to Test

How do I execute my Failover Plans?

If your production site goes offline after a disaster, you can perform full site failover by running a configured failover plan. Click here to view how to execute, undo or finalise Failover Plans.

What is a Permanent Failover?

With permanent failover, you can permanently switch from the original VM to a VM replica and use the VM replica on the cloud host as the original VM. Note that this is permanent and arrangements should be made with Zettagrid to continue running the VM within the Zettagrid IaaS Platform. Click here to view how to complete a Permanent Failover.

What is a Partial Failover?

A partial failover is the scenario where you still have infrastructure up and running, and only one or more virtual machines are having issues. In this situation, a complete site failover isn’t required to solve the issue. Partial failover allows you to start the replica VM of one or more VMs at Zettagrid and let all the other VMs continue to run at your client side. Click here for a detailed overview.

How do I execute a Partial Failover?

To initiate a partial failover, the client selects the virtual machine to be failed over from the replicas that are in a ready state. Click here to view how to execute a Partial Failover.

How much Bandwidth is needed for Replication?

The bandwidth requirements for Cloud Connect Replication jobs will vary depending on your backup jobs and you connection to the internet. Click here to find out more.

How is billing worked out and what will a failover event cost?

Cloud Connect replication is billed in two parts:

  • Base Monthy Charge
  • Failover Charge

Click here for a detailed explanation plus an example in the event of a failover.
