Hello everyone,
i have some questions to tiered storage. We used until now a VPLEX with 2 VNX2, made one big pool over all 3 tiers and it worked "ok". No IOPS limitations for singleservers, only automated optimizations.
Now with the 3PAR we have most space on NL disks and a few upcoming servers with MSSQL on it that needs the best IOPS we can give them. So, how to setup best? Yes, pure SSDs would be the best but we need to look still at the costs.
So my questions are:
- Would it ok to setup 2 AO configs? One over all 3 tiers (balanced) and the other over FC+SSD (for a few high prio servers?)
- Would it work to place most Operating systems only on NL disks outside the AO part?
We are mostly on windows based OS, Hyper-V & VMWare. I dont know if it will work that the OS is on NL. We would make LUNS for logs and DBs on the balanced AO Stuff.
Problem is: We are only a few guys for a big bunch of virtuell servers (and 1000 other things) and until now we dont have time to look after each server. We have totally mixed servers. Some SQL, some webservers, some application server and so on.
Can someone perhaps give me some ideas to work with?
