Is anyone running the IBM 900 or V9000 AFAs?
Can you speak to what happened to your SQL workloads after you switched from whatever you had before to the IBM array?
Specifically, did you see an increase in VM CPU consumption after switching?
As the story goes, SQL is experiencing high I/O Wait, you put that workload on an AFA and BOOM, the I/O Wait goes away and your CPU pegs. Makes sense at face value. The question really is whether the IBM solution, which cuts out all SSD drive overhead by essentially using PCI cards, improves storage access times significantly more than SSD based AFAs.
