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."The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."
"We are happy with the support that IBM provides us."
"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"The most valuable feature is its reliability."
"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."
"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 ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."
"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."
"The scalability is very good and the solution is stable and reliable."
"I like that we could choose whatever hardware we wanted, rather than having to use one particular vendor."
"I have found that the multi-homing feature is very valuable in VMware vSAN. It is an easy-to-use solution."
"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."
"All the features are working great."
"The lower skill cost of maintaining it meant that we could do more with the people that we had."
"Storage is expandable with no extra cost."
"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."
"For improvement considerations, I would probably say multiple sites."
"The disk reliability is not that good."
"Adding features for data deduplication is one area of improvement."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"GUI should be developed in HTML5 as opposed to Java."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"I would rate the stability a seven out of ten."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."
"External storage would be a good thing to have in the next release, something other than iSCZI, something a little more, not HA, a little more production-oriented, than iSCZI."
"The solution functions as the marketing says, as long as you follow certain rules."
"While I like the replication and compression features, there is a problem with them running too slowly."
"The platform’s pricing needs improvement. Additionally, there should be an appliance module included in it."
"It can be very expensive."
"Customers who are using Essentials Plus or even Essentials have to pay for technical support. However, they should not have to pay for support."
