NAS Analysis (NAS and Unified Storage Analysis) in Veritas Operations Manager Enterprise Server 5.0

The NAS and Unified Storage Analysis is a part of Veritas Operations Manager Enterprise Server NAS Analysis reporting package.

See NAS Analysis in Veritas Operations Manager Enterprise Server 5.0

NAS and Unified Storage is a generic namespace that provides capacities of all NAS objects like physical filers, virtual filers, NAS storage pools, NAS volumes, NAS file systems, and NAS quota.

Table: Virtual Filer Metrics displays some commonly used virtual filter metrics.

Table: NAS Volume Metrics displays some commonly used NAS volume analysis metrics.

Table: NAS File System Metrics displays some commonly used NAS file system metrics.

Table: LUN Metrics displays some commonly used LUN metrics.

Table: NAS Share Metrics displays some commonly used NAS share metrics.

Table: Host Metrics displays some commonly used host metrics.

Table: Physical Filer Metrics

Metrics

Description

Total Capacity

Total physical storage capacity of the array.

Total Logical

Total storage capacity of the volumes provisioned to virtual filer.

Logical Used

Used capacity in the volumes.

Logical Available

Available capacity in the volumes.

Replication Capacity

Capacity of LUNs that are designated as target LUNs for snapshot or replication techniques.

RAID Overhead Capacity

The storage that is reserved for overhead most commonly for RAID techniques such as mirroring and striping.

Snapshot Reserve

For unified storage devices, the total amount of storage that is reserved for snapshots in the file system.

Overwrite Reserve

Overwrite reserve determines how much space on a volume Data ONTAP will be reserved for snapshot copy.

NAS Used Capacity

Represents the NAS file system capacities belonging to the filer.

No. Of Volumes

Number of volumes that are created from the physical filer.

No. Of Shares
