For me and for the operations team, the ease-of-use of the GUI is the most valuable feature. It's really easy to understand. It's really easy to do tasks. That's what I like most. The performance is really good. From an operations perspective, definitely the ease-of-use stands out. Compared to other products and other vendors, it's much, much easier.
Improvements to My Organization:
Time to value. You finish things a lot quicker. I can provision the storage a lot faster and find problems a lot quicker. The fact that I can SSH in and do CLI commands where some of these other vendors don't let you do it is a big deal. I can write custom scripts and do things a lot quicker. The ease-of-use is a lot better with this product.
Room for Improvement:
There's always room for improvement. Adding deduplication would allow us to get more bang for our buck, basically.
Overall, stability is really, really good. We ran into some issues with compression, but it was because we were trying to overload it. So if we don't do that, it runs really, really well.
We have it architected to keep it at a certain level. But if we needed to, we could scale it pretty easily because it's virtualized storage. There's a lot of flexibility with it.
Technical support is really good. Because we're a bigger company, they get to us a little bit quicker. There's more on the line for IBM, so they really treat us well. It's been pretty good. We get good feedback quickly.
We needed the performance of the applications. Payroll applications are very I/O intensive and flash systems are a perfect fit. It makes sense.
I was involved in the setup and it was easy. I've done those for years.
Other Solutions Considered:
We looked at pretty many vendors. Anybody you could name, we looked at them. We have multiple vendors in the environment, not just IBM. But for our really critical, high performance apps, we put it on the V9000.
Just be careful if you're going to try to use compression, because of the specific issues we've had. If it's a high performance computing environment, just keep it thick provisioned. Get the best performance from it. Don't try to save and then screw up the user experience.
If something fails, it's not going to bring down the application. V9000 is redundant through and through, so it's a great product.
When selecting a vendor, stability, ease of use, and resiliency are the most important things.
