We performed a comparison between IBM Spectrum Virtualize and Microsoft Storage Spaces Direct 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."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."
"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 most valuable feature is its reliability."
"We are happy with the support that IBM provides us."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"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."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"Its technical support is excellent."
"The flash ability, in terms of tiering and caching, is amazing"
"The performance, reliability, and affordability has been most valuable."
"The most valuable feature are the caching capabilities using the storage class memory."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The most valuable feature is that there is no single point of failure."
"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."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"GUI should be developed in HTML5 as opposed to Java."
"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."
"In general, the migration is complicated. Though, it is case-by-case."
"I think the online documentation needs a lot of work and so do the sizing tools."
"Documentation management could be improved"
"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."
"More optimization could be done in terms of mirroring."
"It is difficult to get a hardware compatibility certification for the solution."
"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."
