Hi guys,

i am wondering how to set up a raid10 on a 3par 8450. In my CPGs i only have the Option between raid1, raid5 and raid6. Even i i want to create a new cpg, it offers the same raid Levels. I know that raid 10 is a raid 1+0 but how do i build that in the 3par?

Thanks

Daniel

The RAID1 type is effectively RAID10. The 3PAR will create RAID10 logical disks in the background.

As for RAID5 is RAID50 and RAID6 is RAID60.

Wait a moment. What's "RAID 50" and "RAID 60"??

RAID10 is a mixture of RAID 0 and RAID 1, Mirroring and Striping, abbreviated as "RAID 10".

But RAID5 is - just RAID5? Am I missing something?? :shock:

RAID50 is data striped across RAID5 raid sets and RAID60 is data striped across RAID6 raid sets.
If you click the Advanced Options in SSMC when creating a CPG or look at the settings of a CPG using cli command showcpg -sdg you will see how each raid set will be configured. For example RAID 5 3 data + 1 Parity.
