Host Utilization Detail (ASM Example)
IT Analytics reveals the following:
ASM Storage Usage that the Filesystem Does Not Report: Oracle ASM does not use a mount-point for storage usage. Since this storage is managed by Oracle ASM, it is unknown to the filesystem.
LUN-to-Host Perspective: The number of LUNs used for the ASM instance on the host provides a complete picture of storage usage. Without the exposure that IT Analytics offers, the number of allocated/used LUNs would be smaller--that is, your view of storage usage would be incomplete without the inclusion of ASM usage.
Mapping of ASM Volume to Storage Tier: By exposing the Array storage used for Oracle ASM instances, capacity and chargeback numbers become more comprehensive and accurate.
Along with traditional filesystem usage, the IT Analytics Host Utilization Detail report incorporates ASM Disk Group usage. In the above example, the first three rows of the Volume table display ASM Disk Groups. This Host Utilization Detail report provides additional physical disk details, raw disk paths, and aliases (see example below).
