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."The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."
"We can have multiple systems within the same file system."
"Allows us to share files across multiple environments."
"It is a scalable solution."
"GPFS monitoring is the best feature."
"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."
"Its great servicing high availability. That is what it is used for."
"The technical support is good."
"VMware vSAN is compatible with the legacy hypervisor solutions and most of the features are good."
"It is simple to manage, very easy to implement and troubleshoot in case of any failures."
"VMware vSAN is easy to implement in a VMware environment and it is not expensive."
"The solution is simple to use compared to other solutions, such as Hyperflex, VxRail, and Nutanix"
"In my opinion, vSAN is the most natural way to migrate to a fully hyperconverged solution. If a customer needs a more scalable solution with consolidated management, vSAN is excellent."
"Stretched Cluster is one of the big features that we use across multiple data centers."
"VMware vSAN is easy to configure, with basic functionality and the customer can maintain the solution."
"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."
"The solution's pricing could be better."
"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."
"Integration with other vendors is not available."
"I believe there is no graphic user interface, so they should include it."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"The customer service is good but there is a cost for it. It does not come free."
"Reporting currently depends on third party applications and that could be improved."
"Dedupe in non flash drives can be improved."
"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."
"There could be more features with the automatic backup."
"This solution is not great for large file shares/object/rich media repository."
"There needs to be an increase in the supported memory and hard disk space, as it is an area where the product currently has certain shortcomings."
"VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement."
