HP StoreOnce Enterprise Manager User Guide

3. On a Gen3 multi-node system, click a service set link, and then click NAS Status.
The library and replication status are displayed in a table. In addition, there are two graphs:
• NAS Disk Usage—The used space (includes disk space occupied by NAS in the current
service set and current group), others (includes disk space occupied by the other service
set in the same couplet, disk space occupied by virtual libraries and CatalystStores in the
current service set, disk space occupied by NAS in the current service set but in a different
group, and StoreOnce bookkeeping data), and free space.
• Couplet Disk Usage—The space used by each node, couplet free space, deduplication
ratio, and amount of user data stored on the couplet of the selected service set.
The table to the right of the graphs lists all of the NAS in the current service set and current
group along with the physical disk space used, the user data stored, and the deduplication
ratio.
