I plan to install some Oracle Database servers 9i on VMWare ESX 3.5. I use an EMC CX3-10 SAN. I want to split the installation into three parts on the SAN : Oracle software / Database / logs.
My questions :
- is it a good idea for performance / availability in accessing my data ?
- Should i use vmfs for those the 3 Luns i want to create ?
- If my system partition is sized at 10 GB, My data 50 GB and my logs 10GB how much space should i count on the luns (20 GB / 100 GB / 20 GB for snapshots ?)
- If i install 4 Oracle servers, should i create 4x3 = 12 LUNS ?
Thank you for your answers
