RAID CONFIGURATION WITH HOT SPARE
Hello Dell And others,
I know this is a low brainer but I appreciate any feedback.
This is about Raid Array having hot spares.
1. Raid 1 (Mirroring)
Does raid 1 need hot spare to perform fault tolerance?
2. Raid 10 (Stripe and Mirror)
For Example, I have 4 SAS Drives configured in Raid 10, Does This one also need a hot spare to perform HA?
3. Raid 5 (Striping)
I Have 3 HDD (600 GB Each) configured in Raid 5 with a logical volume capacity around 1.2 TB.
Do I need to have a hot spare for this one in order for the parity to perform HA?
I Hope you can help me with my confusions.
Thanks a lot!
