Minimum Disks

Is it possible to use RAID 10 with only 2 disks ? I understand RAID 10 to be:

2 mirrored sets
striped data across the 2 sets

please correct me if I am wrong.

Re: Minimum Disks

Technically NO.

However most RAID controllers call 2 disks mirrored this name i.e SA 5i in my DL360 G3.

On the MSA if you have more than one mirrored pair in an array it automatically stripes across them, thus creating a RAID10 set in the process.

Re: Minimum Disks

RAID 10 cannot be created with two disks. You need two mirrors.
