What is our primary use case?
We run our 50+ virtual servers on SimpliVity and also use it for backups.
How has it helped my organization?
The all-flash storage in SimpliVity provides much better performance that the spinning-disk of our previous virtualization system. The extremely fast backups and restores (typically less than 1 minute) enable us to easily backup all our VMs every 2 hours. Lastly, the incredibly high data reduction ratio through compression and deduplication enables us to store 38 Days of full backups done every 2 hours in a remarkably small space. We're currently seeing a data reduction ratio of almost 300:1.
What is most valuable?
Backups and restores occur very quickly.
HPE Technical Support has been very responsive to any problems we've had.
All SimpliVity management is done through vCenter, providing a single-pane of glass for all management and configuration functions.
The advanced deduplication and compression greatly reduce the storage requirements, reducing the amount of expensive flash storage required.
The 10G interfaces between the SimpliVity nodes greatly speeds up VM migrations between nodes.
SimpliVity enables "stretched-cluster" operation with mirrored storage between the nodes, enabling automated failover. If a node or site goes down for any reason, the VMs on that node are automatically restarted on the other node.
What needs improvement?
Although HPE has made significant improvements, the upgrade procedure is still overly complex. It's gotten much easier but it's still far from double clicking on a link and a self-upgrade scenario. Therefore, installing SimpliVity upgrades is an area that HPE could improve upon further.
Performing file-level restores, which is the most common backup recovery operation that we do, also seems more complex than it needs to be. The recovered files/folders are restored to an ISO file, mounted as a DVD, and then they need to be copied from that. Afterwards, the ISO needs to be removed from the VM and then deleted from the SimpliVity storage. It gets the job done but it's kind of clunky.
For how long have I used the solution?
We've used the solution for three years.
What do I think about the stability of the solution?
The stability is, for the most part, pretty good. I won't say we haven't had problems.
Our biggest problem has been SSD failures. Over the three years we've had it, we've replaced over half of our SSDs due to drive failures. Of course, it's all been under warranty and therefore it hasn't cost us anything other than a lot of time and headaches. I suspect HPE received a bad batch of SSDs from their SSD vendor and many of them ended up in our system.
How are customer service and support?
Technical support has been good. They have been very responsive to our SSD failure issues and we usually have a replacement drive in hand within 2 hours of calling HPE SimpliVity support. We have had a few software issues and, again, the HPE support has been very responsive and usually quickly resolves our problems.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
Our previous solution used three VMware servers and two mirrored SANs. The servers were end-of-life and the SANs were almost out of available storage space.
How was the initial setup?
The initial setup and configuration was reasonably complex and we used our local HPE reseller to assist us.
We have two nodes and it probably took a couple of hours per node to get everything configured and working. Then it was just a matter of migrating our VMs from our old system to the new SimpliVity system.
What about the implementation team?
We used our reseller for the implementation. We have a local HPE shop here that we buy most of our network and computer equipment from and they came in and did most of the initial configuration. They were extremely knowledgeable and I doubt we would have been able to get everything properly configured and operational without them.
What's my experience with pricing, setup cost, and licensing?
Since we were faced with having to replace our entire VMware system (three host servers and two SANs), we found that the cost of a two-node SimpliVity hyper-converged system was very close to what it would have cost to build a comparable conventional discrete system.
Which other solutions did I evaluate?
We evaluated Dell VxRail, VMware vSAN, and Nutanix.
What other advice do I have?
We're customers and end-users.
I'd rate the solution as an eight out of ten.
We really like it. As stated earlier, most backups take a minute or less. Within our first year, one of our SQL servers got corrupted somehow and wouldn't boot. We restored the VM from the previous backup, which was at that time about an hour old, and in under a minute we had that 950 GB VM up and running. Restoring this VM with our old backup system would have taken six or seven hours. For us, this was a real eye opener.
I'd advise potential new users to definitely do some kind of a trial, if at all possible, and go into it with their eyes open. We had a pretty good idea of its capabilities beforehand. Although we didn't do a trial, we had witnessed several demos of it. Overall, we've been pretty happy with it. However, like any product, there are always a few things that could be improved.
Which deployment model are you using for this solution?
