VSP and Granite Storage Specifications
The following table summarizes the following information:
Possible disk space allocations between VSP and Granite on xx60 model appliances.
Granite Input/Output Operations Per Second (IOPS) on xx60 model appliances.
With EX 2.0, you are not constrained by the VSP and Granite disk allocation. You can use the local LUN
feature on Granite to allocate as much disk space as you want for the VM local datastore and use the rest
for the Granite blockstore. To do this, select Granite Only mode. Then, set up a local LUN in that space for
VSP, format it using VMFS, and add the VM datastore. (The VM datastore provides storage for VM files.)
You can use the rest of the space for the Granite blockstore.
Important:
For optimal performance, Riverbed recommends direct storage and not iSCSI unless disk sizing flexibility is absolutely
necessary.
For Granite-only allocations, the system reserves a small amount of disk space for VSP for local swap space.
You need a Granite license for Granite-only allocations, for VSP-only allocations, and to access the disk space allocated
for Granite storage in a mixed allocation.
Numbers in parenthesis represent the maximum amount of space available for the component when the
appliance’s disk layout is set to an extended mode. See
“Reclaiming Disk Space” on page 17
