Today I completed the initial performance testing of my EMC XtremIO PoC system.  I wanted to take a shot at it myself before the EMC SMEs come in to tune and optimise the configuration.  In a single word, “Wow!”  This is the first time I have witnessed 400,000 IOPS in any kind of enterprise lab.  I look forward to seeing what additional tricks the experts can make my “X-bricks” perform.

Business Requirement for XtremIO

I can imagine people reading this and asking, “Why?  It is so expensive!”.  Well, the organisation I work for uses monolithic storage (EMC Symmetrix VMAX) which has been sized for capacity, and after 2 years of use we are feeling the impact of performance degradation as we consume the total capacity of the solution.  My business requirement is to create a small but powerful “High Performance” cluster of compute, network and storage that will provide low latency, high I/O resources for my business critical applications that are currently suffering.  This XtremeIO PoC is an attempt to meet that business requirement; I am also seriously considering hyper-converged infrastructure and server-side flash-cache acceleration as well.
