We performed a comparison between IBM Spectrum Virtualize 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 most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"The most valuable feature is its reliability."
"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."
"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."
"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."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage."
"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."
"Most valuable features include replication and compression."
"Without any extra costs, I was able to provide a redundant environment."
"High reliability with commodity hardware."
"It has helped to save money and scale the storage without limits."
"The solution is pretty stable."
"We have not encountered any stability issues for the product."
"Anything which improves performance and the ability of our systems would be a nice."
"Adding features for data deduplication is one area of improvement."
"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"In general, the migration is complicated. Though, it is case-by-case."
"The Storwize port is not so stable."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"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."
"Routing around slow hardware."
"The management features are pretty good, but they still have room for improvement."
"The storage capacity of the solution can be improved."
"I would like to see better performance and stability when Ceph is in recovery."
"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."
"The product lacks RDMA support for inter-OSD communication."
"Rebalancing and recovery are a bit slow."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
