What is your hardware config and CPG settings.
So hardware wise we have 3 shelves, 1 NL, 1 Half Full with SSD and 1 50/50 SSD and FC disk.
we have 6 CPG's, 1 for each disk type for direct presented LUN's and 1 for each disk type for AO, which is how most of our disks are presented.
SSD Settings:
Direct Settings:
Device type SSD 150K
Raid type RAID 5
Availability
Requested Magazine (Lower)
Current Magazine (Lower)
Set size 5 data, 1 parity
Step size 64 KiB
Preferred chunklets Fast
Disk filter -t r5 -ha mag -ssz 6 -p -devtype SSD -rpm 150
AO Settings:
Device type SSD 150K
Raid type RAID 5
