Support for RAID 1E??

Kiran had a RAID support question:

Hi Experts,

 

Do we support RAID 1E in our ProLiant Servers (DL/ML/BL) ?

Hi Kiran,

 

RAID 1E is similar to RAID 5 or RAID 3 in that it is not fault tolerant if two drives fail.  

 

No we do not support 1E Raid for our Proliant SMART Arrays.  

Raid 1, Raid 1+0, Raid 5 and Raid 6 (ADG) is what we support.

RAID 1E uses 2-way mirroring on an arbitrary number of drives

For example, mirroring on 5 drives would look like

A1 A2 A3 A4 A5

A5 A1 A2 A3 A4

B1 B2 B3 B4 B5

B5 B1 B2 B3 B4

Thanks Bruce. Any comments or questions?
