Hi Guys,
I have been obsessing over this configuration of a server and would appreciate some input as I am afraid of forging ahead and implementing a crippled system.
We have a DL385 G7 with an onboard P420i + BBWC + SAS Expander card and 11 x 146GB 15K SAS drives. This server is going to be rebuilt as an ESXi server hosting 7 VM's with a wide range of uses. I am confident of having enough CPU and RAM but am worried about disk throughput. Sadly, I cannot provide any I/O requirements for the eventual VMs as they will be fresh built. .
I was planning to split off two or three of the high disk load servers (2 x Terminal Servers and 1 File Server also hosting a mail server) onto a RAID 10 and having a second RAID 5 for all other servers.
My question was whether what I propose above is a good idea but also whether it is wise to have a single controller managing both drive cages and two RAID arrays? Will I create a bottleneck?
Any help would be well received :) Thanks
