We performed a comparison between IBM Spectrum Virtualize and VMware vSAN based on real PeerSpot user reviews.
Find out in this report how the two Software Defined Storage (SDS) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."
"The most valuable feature is its reliability."
"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."
"The SVC gives excellent performance with tiered storage behind it."
"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."
"I like that it can virtualize more than three hundred storage providers."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"The scalability has been quite good."
"Very good VCG notification feature."
"The solution is quite stable."
"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."
"The most valuable features are its performance, simplicity, and synchronicity with vSphere."
"I have found that the multi-homing feature is very valuable in VMware vSAN. It is an easy-to-use solution."
"It easily integrates with all types of storage."
"This solution has a dashboard that you can log into and control if you need too while the VM is getting created."
"GUI should be developed in HTML5 as opposed to Java."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"Adding features for data deduplication is one area of improvement."
"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."
"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."
"Anything which improves performance and the ability of our systems would be a nice."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"For improvement considerations, I would probably say multiple sites."
"The product's high price is an area of concern where improvements are required."
"I would like to see some of the more traditional SAN functions that are out the now. I can list them: being able to Snapshot on the back-end, better de-dupe, and better compression. Those are the major ones."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
"The monitoring feature in VMware vSAN could be better."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"This solution could be improved by having more than one controller for the environment. VMware depends on one controller for the whole environment, whereas Nutanix has one controller for each node. Because there is only one controller with VMware, if there was any drop, then the whole environment would stop working. In Nutanix, I have five nodes—there is one controller for each node and it depends on a virtual controller—so if the controller of any node is down, the whole environment will still work."
"It should be easier to use."
"The price can be reduced. Small businesses cannot afford this solution."
