Dears,
I have a database distributed on 6 luns as per the below on a SAN Storage:
lun01 6 physical disks raid 5 --- datafiles + conrol file
lun02 6 physical disks raid 5 --- datafiles + conrol file
lun03 6 physical disks raid 5 --- datafiles + conrol file
lun04 4 physical disks raid 1/0 -- redo logs
lun05 2 physical disks raid 1 --- oracle_home
lun06 2 physical disks raid 1 ---- Archive logs.
We are moving to a new ALL FLASH ( NVMe) storage, and the above architecture is not an option anymore on the new storage.
we are creating a Raid 5 pool with 2 hot spares. and distributing luns in this pool .
My question :
- What are your recommendations in such cases ?
How should we distribute our files ? should we keep the same Luns on the new storage ? or move them all to one Lun ?
Is it logical to put all the above files ( datafiles, control files , redo-logs and archived redo-logs) in one pool ?
Thank you
