We performed a comparison between IBM Spectrum Scale 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."GPFS monitoring is the best feature."
"Its great servicing high availability. That is what it is used for."
"The profile share is a valuable feature."
"We can have multiple systems within the same file system."
"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."
"It is a scalable solution."
"We are using it for monitoring all of our storage."
"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"It is easy to use. It is easy to implement for us, and it is also easy to maintain for the customers. It is not necessary to buy some extra devices and talk with other vendors."
"The most valuable feature is the ability to continue our business needs and have higher visibility. It has definitely increased our business productivity levels."
"The most important functionality is the ability to extend cluster storage and cluster computing power securely without loss of data."
"The most important feature to me, in my role, is cost. In the renewal cycle for storage, it was about a 40 percent saving compared to going to an all-flash array, which is what we first looked at doing. Secondly, performance: we need clinical data access in five seconds and need to do everything we can to retain that metric. Thirdly, I was really pleasantly surprised during the data migration across to vSAN, that it happened almost instantly whereas, in the past, migrating from array to array was an arduous and fraught process."
"The most valuable feature is that it is software-defined storage. Also, being able to do maintenance on the fly is a real benefit: migrating off, updating, and then moving the guest back on to the nodes."
"vSAN that has been most effective in streamlining storage operations. For data recovery alerts, it uses tools like snapshots and vMotion."
"It scales well. We have plenty of room to grow."
"The product’s most valuable features are performance and expandability."
"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."
"The biggest problem is that it is not able to provide block storage."
"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."
"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."
"Maybe it needs integration with HA."
"Integration with other vendors is not available."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"The solution's pricing could be better."
"While I like the replication and compression features, there is a problem with them running too slowly."
"There are certain shortcomings in the stability of the product where improvements are required."
"Its price could be improved. It is too expensive for our clients."
"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."
"There could be more features with the automatic backup."
"One area that could be improved is the management feature."
"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."
"The platform's cost affects the business. This particular area needs improvement."
