XtremIO was originally purchased to provide a high-performance storage platform for our critical systems. It is being used across the entire organization as a storage option in our VMWare environment for high-performance datastores. We also use it for some FC attached storage for our physical servers which run AIX.
At the time the EMC was selected due to the existing relationship with EMC and the maturity of their product compared to the other vendor's options. However now that the maturity gap has been closed and the storage wars have proven which companies will remain for the foreseeable future, we have decided to move away from the XtremIO and go with an alternate storage company due to the price and cost of ongoing support. The EMC product is still a great product, I just find it too expensive to purchase and maintain in today's competitive marketplace.
This was one area of real disappointment. EMC support was very slow to schedule work like installations and upgrades. Break/fix support was fairly standard. After the Dell merger, things have started improving but there is a lot left to be desired here.
We refreshed our traditional storage solution from Hitachi VSP to Dell EMC XtremIO Flash storage part of our converged consolidation project. We were pleased with the I/O effects and noticed significant improvements to our mission critical applications. We were so impressed that we refreshed our lower/testing environment to XtremIO.
I specifically like de-duplication, compression, high I/O, thin storage allocation, snapshot (to refresh our lower env from production systems). Because of XtremIO we are now able to create instant copies with space-saving data de-duplication technology for our lower environment with easy refresh/restore operations.
