HI
We are hitting som performance issue with virtuals machine using the NFS protocoll and cifs share.
I am in need of some tips on how to design our storage to minimize our performanxe issue. We have decided to try to use of the NFS protocol as far as it gets.
We have three different levels of SLA and function high, medium and low.
High is the SAS disk
Medium one volume with SAS and one with SATA.
Low is only SATA.
We have put most of the servers in the low volume around 80 out of 100.
We have SAS = 113X190 = 21470 IOPS + 35 ~ 40% cache
SATA = 40x40 = 1600 IOPS + 35 ~ 40% cache
We have some problems with it is slow to copy small files and some latency problems.
