We performed a comparison between IBM Spectrum Virtualize 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 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."
"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."
"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"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."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"The ability to have an HA cluster in the absence of a shared storage device or SAN."
"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."
"The most valuable features are its performance, simplicity, and synchronicity with vSphere."
"The newer versions of this solution are much more stable and easier to manage."
"The deduplication and compression are excellent."
"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."
"The most valuable features for us are the ability to scale out the nodes independently, and the flexibility of the nodes. We can put almost any type of server in there with our connectivity and everything works great."
"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."
"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."
"GUI should be developed in HTML5 as opposed to Java."
"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."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"The Storwize port is not so stable."
"The disk reliability is not that good."
"Level 1 technical support needs improvement."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"VMware vSAN could improve by adding NAS and object storage."
"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."
"We are facing some problems with updates with the VMware vSAN. When we upgraded from version 6.5 to 7, we have been faced with many problems. They have been deploying many hotfixes for this version, and they need to continue to improve this version."
"Hackers are able to manage to leak information or data from the product using some corrupt files, making it an area of major concern where improvements are required."
"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."
"There's already a concern with VMware with ransomware and security issues. VMware could focus on improving security."
"The solution could be improved by having more filtered and multiple view volumes instead of a single view."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
