Good automation with seamless failover saves us time, but it needs better granularity when used with array based replication software.
Pros and Cons
  • "The most valuable feature is the automation, where you press a button and everything fails over seamlessly."
  • "You cannot use VMware SRM in conjunction with storage replication software."

What is our primary use case?

We are a solution provider and this is one of the products that we implement for our clients.

VMware is being used for disaster recovery to protect two sites.

What is most valuable?

The most valuable feature is the automation, where you press a button and everything fails over seamlessly. It is quite good.

What needs improvement?

When used in conjunction with storage replication software it is not possible to separate and failover an individual VM. When the VMs are sitting on the same storage LUN, the granularity is not sufficient.  Ideally, we should be able to choose one virtual machine and separate it from the rest.

If the price were more competitive then it would be very good.

For how long have I used the solution?

I have been working with VMware SRM for about five years.

What do I think about the stability of the solution?

It is stable for now. I haven't had any issues.

What do I think about the scalability of the solution?

It is scalable, although the downside to scaling is the cost.

How are customer service and support?

When I first contacted technical support, I had some issues. However, as time went on, the support has improved and I now think that it is okay.

Which solution did I use previously and why did I switch?

Prior to using VMware SRM, we were doing everything manually. Failover of VMs was done manually from promoting the replicated LUNs to read write and then bringing them up in the DR VMware environment.  It was a lot of manual work when dealing with hundreds of VMs.

How was the initial setup?

The initial setup is all right and we have had no issues with it.

What's my experience with pricing, setup cost, and licensing?

The cost of SRM is a little bit high, especially for smaller companies.

Which other solutions did I evaluate?

Yes Veeam and RecoverPoint for VM

What other advice do I have?

In summary, this is a mature product that works very well. It is easy to set up. I like the fact that it has a bubble test feature that allows you to test your configurations without actually failing over. However SRM is very pricy.

I would rate this solution a seven out of ten.

Which deployment model are you using for this solution?

On-premises

We've been using the product for the past year. 

What do I think about the stability of the solution?

VMware SRM is very reliable and stable. 

What do I think about the scalability of the solution?

The product is very scalable. 

How are customer service and technical support?

I'm satisfied with the technical support we've received.

How was the initial setup?

The setup is relatively complex because of how we use it so the setup can take some time.

What's my experience with pricing, setup cost, and licensing?

We pay an annual licensing fee for the product. 

What other advice do I have?

I would recommend the product to anyone requiring a disaster recovery process. 

I would rate this product an eight out of 10.

It helps execute a playbook to bring up your DR site after failing over a group of VMs to it, although I'd like more tools to help with editing the embedded databases.

What is most valuable?

Site Recovery Manager is valuable because it helps with the difficult problem of failing a group of virtual machines over to your DR site and bringing them up. Because there's things that must be changed in a machine in order to bring it up somewhere else like maybe its IP address or, you know, any slew of other things, the port groups or whatever it needs to be connected in, and you can either manually do all that by hand or you can program your recovery plan in Site Recovery Manager and it's pretty much, you know, menu driven because it's common things that you would have to do to a server in order to bring it up somewhere else, and you can go in there and you can actually have it prompt you to say oh, by the way, you need to turn on the database server before you turn on the next server. And it pauses and waits there so you can go over here and turn on your database server and then you click dismiss and it goes to the next step. Which you wrote all these steps into the Site Recovery Manager so that's what it does. Really helps execute a playbook for you to be able to help bring up your disaster recovery site.

How has it helped my organization?

You know, I've gone to a lot of Site Recovery Manager training here and stuff. One of the things that I think that they minimize is that normally you'll never use your DR site. But what you have to do every year is test your DR site.

What needs improvement?

Yeah, I would like more tools to help with editing the embedded databases. I have run into some issues where human error, not something that VMware themselves would have ever planned for, but human error, has caused the system to get out of sync. And the only way to correct that would be to actually manually edit the database, which you could do if Site Recovery Manager were on a Window server but now that everything's gone to this, Linux appliance, this sealed up appliance, it's very difficult to actually edit the database. Or maybe just have a reset button for them to be able to put everything back to a normal state. Maybe that's all they would need to do.

What do I think about the stability of the solution?

It's a very stable product. It is as scalable as VMware is itself.

What do I think about the scalability of the solution?

It's really just an add on to the virtual center. It used to be responsible for replicating. It is no longer responsible for replicating. The replication portion of Site Recovery Manager has been moved to vSphere itself. A lot of people may not know this. So you do not need to buy Site Recovery Manager in order to replicate VMs around. You can do that for free. But the automation piece that I'm telling you about and the playbook and stuff is what you buy Site Recovery Manager for now.

Which solution did I use previously and why did I switch?

I was responsible for designing and implementing a DR solution for my company and being that we're on a VMware environment it seemed only logical to go to VMware first because all the machines that I need to put at my, disaster recovery site are virtual servers I was like well I'm sure VMware has a solution.

Being able to test the environment, being able to make the changes to the virtual servers so they could come up on a different network. I needed to be able to go in there and change things like the IP address, the DNS settings and stuff like that to be able for them to come up at a different location.

How was the initial setup?

Least favorite things about Site Recovery Manager. It is a little bit difficult to get it set up the first time you've ever just because it is so different.

What about the implementation team?

Actually paid a consultant to come out and help me, train me on how to install it the very first time I installed it three versions ago but I've done it enough now to where I'm comfortable with it.

Which other solutions did I evaluate?

No, there weren't at the time I did it. I've been using Site Recovery Manager for several years so.

What other advice do I have?

I always think there's room for improvement. They would seriously need to sit down and take a machine. I want to bring this machine up over here on a different network at a different location. And write down all the steps that they would manually do if they were going to do this process by hand. And like I said the replication is free. So they could technically replicate that over there right now today, make a copy of it and go oh, okay, go bring it up over there and write down all the steps that you have to manually do and then multiply that times the number of machines that you have to do for your DR site. 

In my case it's about one hundred. I need to bring up about one hundred servers. Then you sit there and think to yourself okay, so, and you could just, you know, take your watch and say okay, I'm going to start now. I'm going to go over there and see what it takes to get this server up at the DR site. Oh, that took me about 20 minutes. Okay, well, then, you multiply that times a hundred and you're at 200- 2000 minutes, okay. So would you have 2000 minutes’ worth of time to go through and bring, you know, work on all these servers in the-in the case of a DR scenario. And if the answer's no, then you probably should look at something to help you out. Some tool to help you out with that and that's what Site Recovery Manager brings.

Everybody looks at reviews and I look at the negative reviews as well because I feel like sometimes that some of the positive reviews may not have been real but, up, people will always complain about something they don't like. They're the most vocal so for Site Recovery Manager I would probably type in Site Recovery Manager reviews into a search engine.

Good integration and community support to help with mission-critical projects and services
Pros and Cons
  • "The most valuable feature is the integration with our Nutanix environment."
  • "You need a lot of knowledge to work with the interface because it is not really easy to use, and it would be great if the dashboard were simplified."

What is our primary use case?

This disaster recovery solution helps our clients with their mission-critical projects. They are able to maintain business continuity and increase the reliability of their services.

What is most valuable?

The most valuable feature is the integration with our Nutanix environment. If it didn't have this ability then we may not be using it.

What needs improvement?

There are sometimes performance issues when working with outside links, and it would be better if this were improved.

You need a lot of knowledge to work with the interface because it is not really easy to use, and it would be great if the dashboard were simplified.

For how long have I used the solution?

I have been using VMware SRM for approximately two years.

What do I think about the stability of the solution?

I think that this product is very stable.

What do I think about the scalability of the solution?

I have no issues in mind with respect to scalability or flexibility.

How are customer service and technical support?

I have not been in contact with technical support. Usually, I get help from the community. The forums and websites are great for getting help.

Which solution did I use previously and why did I switch?

I don't think that there is another product that serves the purpose that this VMware SRM does. Integration is very important to me, to have the whole environment integrated together in one place. Because of this, I went straight to VMware.

How was the initial setup?

The complexity of the setup depends on the scenario, but some experience is needed for deployment and installation.

What about the implementation team?

Using a consultant to assist with the deployment is common and this is what I recommend to my clients.

Which other solutions did I evaluate?

I did not evaluate other solutions.

What other advice do I have?

I would rate this solution an eight out of ten.

Which deployment model are you using for this solution?

Easy to use and with lowest RPO can protect the main site; add a function to detect the business critical applications.

What is most valuable?

Centralized recovery plans for thousands of VMs, Non-disruptive recovery testing, Automated DR workflows.

How has it helped my organization?

Lowers the cost of DR management, Eliminates clexity and risk of manual processes, Enables fast and highly predictable RTOs.

What needs improvement?

In my opinion if Vmware added some function to detect the business critical applications like oracle, exchange to help monitor these applications for disaster recovery .

For how long have I used the solution?

7 years on many international projects.

What was my experience with deployment of the solution?

In the earlier versions I had some issue, however all of them resolved now.

What do I think about the stability of the solution?

No issues with stability.

What do I think about the scalability of the solution?

No issues with scalability.

How are customer service and technical support?

Customer Service:

Excellent, I had some issues for trouble shooting which was far from my knowledge and vmware customer service remotely solved the problem.

Technical Support:

Excellent

Which solution did I use previously and why did I switch?

Yes, I used other products like Storage replications or some other software like "double take.” The problem with storage replication was that it was so risky and unstable to manually bring the application up on DR site, besides taking more time to restore.

Other software, like double take, we needed to do lot of effort on each application separately which makes the solution more complex.

How was the initial setup?

In some basic installations, it is very straightforward, but for enterprise customers it makes sense to do some extra steps to protect applications and boot order.

What about the implementation team?

Both, In my experience vendor teams like HP, EMC or net app, didn’t have much experience with this product, especially for the last 5 years, I mainly have to help them understand the solution.

What was our ROI?

Based on average of downtime cost on DR and how automation can help to bring the business on, SRM can reduce the cost nearly 50 percent; moreover you don’t need to have SAN storage on DR.

What's my experience with pricing, setup cost, and licensing?

Setup cost was based on number of vms and protection plan, and if communication DR site has no any issue, within two weeks all setup can normally be finished and cost is around $300- $350 per day.

Which other solutions did I evaluate?

For some customer who want to protect small number of of applications, I will recommend to go with vendor disaster recovery solution, like Oracle data guard for oracle DB or Microsoft exchange replication or SQL log shipping for Microsoft SQL products.

What other advice do I have?

Vmware SRM can handle all of the challenge of replication and disaster recovery in a simple way.

SRM - standard disaster recovery for VMware

Most VMware administrators have heard of Site Recovery Manager (SRM). SRM has been the standard in disaster recovery for some time. It plays into VMware’s parent company’s (EMC) product line, traditionally leveraging storage based replication. This architecture leverages write journaling technology we spoke of in our first article in the series, so Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) could be very aggressive.

The down side to this architecture is that the customer has to have similar storage arrays at both the production and disaster recovery site. If for example the customer had a fiber channel array on the production side, and a lower grade NFS array from a different vendor on the other side SRM was not compatible Bummer…

VMware however released vSphere replication in the vSphere 5 family suite and allowed administrators to replicate their virtual machines without common storage subsystems. What this means is that you could have your traditional fibre channel SAN on the production side, and NFS, or internal storage on your disaster recovery site. The underlying storage type is completely irrelevant as long as the workload is supported. This is a gift for DR budgets everywhere. Additionally you can recover to previous points in time using snapshots at the recovery site much the same as you would use a traditional snapshot.

SRM in thie configuration sits on top of the vSphere replication instead of RPAs that are common in array to array based architectures. These replication appliances are Linux virtual machines that are deployed in the VMware environment. I will give VMware a large amount of credit here, where some competing technologies are cumbersome to install, vSphere replication installation takes only a few mouse clicks. Your vSphere replication appliances are functional in just a few minutes. Replication can be configured through the VMware fat client or the web client.

So what’s the catch? vSphere replication would fall into the snap and replicate category. This means that RTOs and RPOs wont be as aggressive as with array to array based replciation, or hypervisor technologies that use write journaling. The current RTOs and RPOs that can be achieved by vSphere replication with SRM over vSphere replication is 15 minutes. There are rumors that this will be coming down to 5 minutes in the future, but it’s only a rumor at this point. Also if you are trying to move to the web client then you will dismayed to learn that SRM can still only be managed through the VMware fat client. I don’t know to many administrators that are excited about the web client, but it’s a relevant piece of information for your day to day work.

So what about the licensing and additional costs? There are pros and cons to the vSphere replication / SRM model.

The virtual appliances are Linux based – pro

This means there aren’t additional Windows licenses required to operate the environment. Some of the other products use Windows based virtual appliances. When you have to stand up more Windows servers you have to patch and manage them, this adds to the cost of the solution. SRM can generally be installed on your Windows system that vCenter runs on. If you’re using the Linux based vCenter appliance SRM isn’t compatable. I would expect this to be resolved soon as VMware is trying to eliminate the need for Windows systems in the environment.

The base vSphere replication is free – pro

Yes you heard that correct, vSphere replication is free. If you have lower priority virtual machines you don’t have to buy SRM licenses. This means you can save money and buy only the SRM licenses (sold in packs of 25) for your mission critical VMs.

SRM is the orchestration tool on top of vSpherer replication – nutural

SRM and all of it’s power can be scoped down to only the systems you need it for. I personally like the flexability and choice, most companies don’t need to replicate all of their virtual machines with very tight RTOs and RPOs. If you are trying to replicate your entire VMware environment, you maybe better off with a solution that licenses by socket as it maybe more cost effective.

Snap and replicate technology – con

At the end of the day snap and replicate technologies are limited. Because the recovered virtual machine ends up with snapshots scalability can be an issue. Let’s look at an example.

VMware recommends that you only have 21 snapshots at a maximum using vSphere replication. More snapshots than this can lead to snapshot consolidation issues. If you wanted to have a recovery point every hour, you wouldn’t be able to recover your virtual machine to a point further back than 21 hours. This a limitation of any snaphost based replication technology not a defiency with in SRM or vSphere replication.

Scalability – neutral

The upper limit to SRM with vSphere replication is 1000 virtual machines. This will suit most enterprises; however, for very large scale deployments this may not be enough. SRM with storage array replication for example can support up to 1500 vitual machines. This limit is roughly about what you would get with any other snap and replication technology. In my personal experience Veeam starts to have problems after 300 virtual machines in a single instance.

Speaking of Veeam this is the next technology that we will discuss. Veeam is a good product that not only provides DR capabilities, but also a very mature backup solution. Join us for our next article in the series.

Nice article - I recently have been looking at Vsan as a viable option for lab POC. Some DRaaS customers have a need to replicate/recover specific workloads outside of the SRM protected groups so they can control failover testing. In real world I do not see many customers using vsphere native replication in conjunction with SRA San layer replication. Vsan requires 3 host Minimum and works with vsphere replication.

Vsphere replication nice free to use pro for sure. Limited use cases as far as enterprise production recovery. Perhaps vsphere replication and vsan combination is low cost future of DRaaS?

Its array-based integration is the most valuable feature

What is our primary use case?

VMware failover is our primary use case of DC DR automation. We are integrated with array-based replication.

How has it helped my organization?

We had not achieved our RTO before the SRM implementation. But now, we have achieved our RTO for DR drill.

What is most valuable?

  • Array-based integration is the most valuable feature.
  • It has a user-friendly dashboard and will use the same vCenter console.

What needs improvement?

DR drill report is good but needs to be improved, and the replication monitoring feature is not available.

For how long have I used the solution?

One to three years.
