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:
- Raw Space: 3.27 TB
- RAID (Hardware): 5
- Usable Space: 2.8 TB
- 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.

Re: HP StoreVirtual Storage (Network RAID10)
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
