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."It provides transparency, because of its advanced copy features."
"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"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."
"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."
"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 performance has exceeded our expectations and exceeded our traditional converged infrastructure."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"Technical support is good."
"vSAN can help customers save on storage system costs, and also save on the human cost."
"The solution has high performance."
"Instead of going for SAN storage, customers can use the scale-up and scale-out features of VMware vSAN."
"The most valuable features for us are the ability to scale out the nodes independently, and the flexibility of the nodes. We can put almost any type of server in there with our connectivity and everything works great."
"Technical support has been fantastic. We always get answers quickly whenever we call."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"The disk reliability is not that good."
"Level 1 technical support needs improvement."
"GUI should be developed in HTML5 as opposed to Java."
"Adding features for data deduplication is one area of improvement."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."
"The solution functions as the marketing says, as long as you follow certain rules."
"VMware vSAN needs to improve its features because other solutions have more advanced features."
"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."
"We would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up."
"The only negative point relates to the licensing. If you want multiple, different servers, it costs money, but you have all the capacity for vSAN. You do not reach the data, but the processor arrays and the current architecture."
"This solution is not great for large file shares/object/rich media repository."
"I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in."
"Virtual machines disk size cannot cap more than a single node. For a VDI user, it may not save enough to hold a file server or exchange server on a single node storage space."
