Flash Read Cache, Swap to host cache and All Flash sotrage
Hi,
If I have all flash SAN storage do I still need to buy a host with SSD local disk for Flash Read Cash or Swaping ? Or I will not gain any benefit since I have all flash storage ?
If you want to use vFRC you still have to have local flash storage. As to whether you would see a benefit the answer is it depends. It depends on how overloaded your AFA is and if you are seeing high latencies on reads. vFRC only accelerates reads and not writes, so it won't help with those.
