We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"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.""I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features.""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."

"The most valuable feature is that there is no single point of failure.""The most valuable feature are the caching capabilities using the storage class memory.""It's mainly about the storage expansion, like in hyper-converged solutions.""The flash ability, in terms of tiering and caching, is amazing"

Cons
"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.""t is limited in terms of a single system to eight nodes or four, what they call IO groups.""The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."

"More optimization could be done in terms of mirroring.""I think the online documentation needs a lot of work and so do the sizing tools.""It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes.""Documentation management could be improved"

Pricing and Cost Advice
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them.""The entry point of pricing for this product is the most amazing price ever in the industry.""This solution came as an additional cost for the TSM package we chose."

"With the data center licensing and everything that is connected to that, this solution is relatively costly.""Cost-wise the product is one of the more affordable within the category of products."
