Hi,

 

I would like to know what your suggested Raid group size and number of disks is by Raid Type RAID-DP. Also would like to have two Aggregates for max IOPS.

Specs:

NetApp FAS2240-2, HA, 24x450GB (SAS 10K), Dual Controller met Data ONTAP

Essentials met Data ONTAP, DSM, MPIO, CIFS, NFS, iSCSI, FCP

en Local SyncMirror

Thanks.

    With this config (assuming a "load balance" HA Setup) you are not facing the raidgroup size question...

     

    two controllers / each with one aggr0 of 11 disks, leaving 1 spare disk per controller...

    PS default raidgroup size with SAS disks is 16 disks per RG (max 28)

     

    RAID-DP (Default)

    ATA/BSAS/SATA: 14     FC/SAS: 16     SSD: 23

    (Maximum)

    ATA/BSAS/SATA: 20     FC/SAS: 28     SSD: 28

     

    RAID4 (default)

    ATA/BSAS/SATA: 7     FC/SAS/SSD: 8    

    (Maximum)

    ATA/BSAS/SATA: 7     FC/SAS/SSD: 14
