Raid 5 space question
Posted on 2004-09-07
I have been asked to build a server with raid 5 that has two hot spares.
Heres the setup.
8 * 136.72GB hard drives.
Now here's the question. this comes to 1093.76, now in raid 5 mode it actually comes to 957.04GB. the 957.04GB does this include a hot spare, or is it just for parity?
If i create a hot spare then i only get 820.32GB, so two hot spares would be even lower.
I've looked at the array manager and there are no hot spares listed.
As you can see i'm not really upto speed with raid 5.
thanks for the help.
