I have a HP proliant DL380 server G4 server and is on raid 5 with 4 hard disk 0f 300GB and the space on C drice 1GB and on D drive only 5GB is left and D is where all our User data is stored.
So i thought of adding another 300 GB harddisk and expanding the array.
I was told i will need to have Battery-Backed Write Cache battery pack to expand the array.
Another person said that if the server is configured on raid 5, i dont need Battery-Backed Write Cache battery pack
I am little bit confused
Any ideas much appreciated.
