ME5 ADAPT RAID
Good day,
I just want to ask related to the ADAPT RAID.
What is the maximum recommended disk groups for ADAPT raid for ME5? is there any difference using RAID 5 or 6 in terms of usable capacity or it will be same?
Best regards,
Merckz

Hi @merckz,
ADAPT is not based on traditional RAID. You can refer to this article for ADAPT concept: https://dell.to/3h3ZWjP
You also can use this PowerSizer tool to calculate roughly the usable capacity: https://dell.to/3DUM5pj

Merckz,
As seen on page 117 here, the maximum supported Adapt disk groups would be 4, but when using drives that are 6 TB or larger it is recommended to use either a RAID 6 Disk Group or an ADAPT Disk Pool. Due to the increased amount of time that is taken to reconstruct and copy-back and the chances for a second drive failure increases on either a RAID 1/10 or a RAID 5 Disk Group. As far as the raid 5/6 question, it would depend on the number of disks, as you can lose more space to parity over time as RAID5/6 max at 16 disks.
Let me know if this helps.
