We performed a comparison between IBM Spectrum Scale and Red Hat Ceph Storage 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 profile share is a valuable feature."
"Its great servicing high availability. That is what it is used for."
"The most valuable feature is the ability to share files across different platforms."
"We can have multiple systems within the same file system."
"Allows us to share files across multiple environments."
"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"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."
"GPFS monitoring is the best feature."
"It has helped to save money and scale the storage without limits."
"High reliability with commodity hardware."
"Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures."
"We use the solution for cloud storage."
"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."
"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives. The solution continues working even when there are errors."
"The high availability of the solution is important to us."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"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."
"The biggest problem is that it is not able to provide block storage."
"Integration with other vendors is not available."
"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."
"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."
"Maybe it needs integration with HA."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"It needs a better UI for easier installation and management."
"We have encountered slight integration issues."
"The product lacks RDMA support for inter-OSD communication."
"If you use for any other solution like other Kubernetes solutions, it's not very suitable."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise."
"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."
"Rebalancing and recovery are a bit slow."
"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."
