HP StoreVirtual Storage (Network RAID10)

Good day,

I have a small question, I cannot find the storage space calculator for below config, so hopefully somebody can help me out.

Current configuration:

2x HP Letfhand P4000, 2x HP Lethand P4200:

  1. Raw Space:  3.27 TB
  2. RAID (Hardware): 5
  3. Usable Space: 2.8 TB
  4. Provisioned Space: 2.59

Currently:

  • Network Raid10 2-way mirror
  • Total Space: 11.5 TB
  • Available Space 0.88 TB
  • Utilization: 92%
  • Disks: (Thick) Full provisioned

What will happen if I add the next SAN node number 5 (HP Lethand 4300) on the same config, or what will the Utilization be?

Best regards,

Henry van der Leer

Hi Henry,

i guess this KB will help you figure it all out.

Henry,

the available cluster capacity always depends on the smallest node of your cluster.

If you use Network RAID 10, than:

Available capacity =  (number of nodes x available capacity of smallest cluster node) / 2 

I.e. assuming that your additional node will provide at least the capacity of your currently smallest node (2.8TB), than you would get:

Total space: 5 x 2.8TB =14TB

Usable capacity (Network RAID 10): 5 x 2.8TB / 2 = 7TB
