We performed a comparison between DataCore SANsymphony and IBM Spectrum Virtualize 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."During the maintenance periods, on any part of the storage or VMware migration, we have had no downtime."
"The synchronous mirror allows us to operate a fully redundant storage solution that is distributed across two sites."
"The interface is user-friendly."
"The most valuable feature of DataCore SANsymphony SDS is its high availability. This solution also exhibits good performance and has high stability."
"The documentation repository is really useful and kept updated."
"Our central storage has very high availability. DataCore SANsymphony ensures high business continuity."
"It is a well-proven, automated management tool in all dynamic provisioning, auto-tiering, great performance, parallel I/O, cache speed mechanism, etc."
"Active-active is the most valuable aspect for us."
"The SVC gives excellent performance with tiered storage behind it."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"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."
"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."
"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 happy with the support that IBM provides us."
"It provides transparency, because of its advanced copy features."
"I still see room for improvement with DataCore SANsymphony in the area of alarm and task management."
"There is no way of quickly matching the exact size of a vDisk to a disk pool."
"It would be ideal if they were providing archive licensing with the ability to create a second pool on existing storage nodes."
"Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial."
"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."
"If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud."
"The solution is constantly evolving."
"There is room for improvement in the graphical interface."
"Adding features for data deduplication is one area of improvement."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"For improvement considerations, I would probably say multiple sites."
"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."
"In general, the migration is complicated. Though, it is case-by-case."
"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."
