Beefed up server - Raid 10

(imported topic written by rdamours91)

I’m getting ready to spec out a blinged out server.

2 - Raid 10 arrays to break up the app and db into their own array. 50/50 raid controllers, etc.

Just wondering what my usable space is in a raid 10 array. Is it (Size of Smallest Drive) * (Number of Drives ) / 2 for each array. So for example 148GB drives with 4 drives in each array = 296 GB usable in each array? I just want to have some space for db backups, etc.

I’ll migrate over to the new server and then wipe my existing raid 5 server and re-setup as a replication target.

Let me know if I’m on the right track…

Hi rdamours,

Yes… I believe you are correct that RAID10 is striped/mirrored so you lose 50% of capacity of the sum of all drives.

Your new array setup should have significantly better disk performance than your old RAID5 array.
