Dear All,

We are facing performance issue in VNX5200.

We have a single pool with FAST Cache and FAST VP enabled.

2 SSD disks of 91GB configured in FAST Cache

Pool have total 41 disks (SSD disk, SAS disk and NL-SAS disk)

SSD disk: 5 disk used in pool with RAID5 configured.

SAS disk: 20 disks used in pool with RAID5 configured

NL-SAS disk: 16 disks used in pool with RAID6 configured

For tiering it show
1780GB(to be moved up),
514GB(to be moved down),
Data relocation time showing (127 hours).

So I thing the issue is less no of SSD and NL-SAS disk?

Please suggest if we have any solution or work around for the same?

Thanks in advance for your kind support.
Regards

AK
