Good morning. We're an SMB-sized governmental entity (10 hosts and <100 VMs) and we're finalizing a list of storage solutions (EMC VNX, HDS HUS, NetApp FAS, Tegile HA21xx and X-IO ISE-2) to replace our aging HP EVA6100s and I've been hearing some rumblings about certain vendors having a "performance knee" that when they've reached a certain capacity, the performance of the array drops precipitously. I wanted to know if any of you experienced anything like this in your environments or whether it might just be a perfect storm of events (undersized/overcommited array, VDI, etc.)? Thank you in advance for your response.
Scott
