I am trying to find out how many IOPs I get if I add FAST Cache to my VNX5800.
I thinking of having 8 x 100GB EFD FAST Cache drives in a RAID 1 configuration and 1 hot spare.
READ/WRITE = 70/30
I know it depends a bit on what type of data we are using.
Is there not a general rule of thumb ?
Thanks for your answer, it helps but I still don't know how many extra IOPs I get when install FAST Cache.
I also had a look in another document: "docu48710_White-Paper_-EMC-VNX-Multicore-FAST-Cache-VNX5200,-VNX5400,-VNX5600,-VNX5800,-VNX7600,-and-VNX8000"
But this document also doesn't describe on how to calculate the number of IOPs with FAST Cache.
I also have the Pool Siser which is a great tool but also doesn't do anything with FAST Cache.
So please keep this topic open because I am still looking for an answer
