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."I like that it can virtualize more than three hundred storage providers."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"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."
"The SVC gives excellent performance with tiered storage behind it."
"I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features."
"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."
"While we haven't made major changes to our disaster recovery and business continuity processes yet, moving towards stretch vSAN across sites will simplify and expedite our DR processes in the future."
"The ability to have a disaster recovery option for our end-users by being able to use VDI and the vSANs, and the ability to do replication across multiple data centers, are valuable to us."
"The solutions best feature is that it is easy to use."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"The scalability of the solution is most valuable."
"It scales well. We have plenty of room to grow."
"This solution has a dashboard that you can log into and control if you need too while the VM is getting created."
"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."
"The disk reliability is not that good."
"The Storwize port is not so stable."
"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."
"Adding features for data deduplication is one area of improvement."
"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."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"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."
"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."
"Improvements are also needed as per the customer's requirements."
"The pricing model is sometimes a challenge for us because their licenses are very costly."
"Ease of administration is one area where vSAN could be improved."
"In a future release, they can bring in the object storage capabilities to this solution. Currently, there is not any compatibility."
"This solution would benefit from better collaboration with Cisco for driver updates."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."
