Predicting storage needs more accurately

Reporting on Your Datacenter
Predicting storage needs more accurately
This example demonstrates how a Storage Manager uses StorageScope to determine
the storage needs for a file system residing on a EMC Celerra
® Network Server (a NAS
storage system) over time. The Storage Manager uses one of StorageScope’s SRM
views to get a point-in-time view of the status of NAS File Systems in the enterprise.
To complete this task, the Storage Manager:
1. Logs in to StorageScope as documented under “Identifying IT assets for
accounting” on page 8.
2. Selects Analysis > SRM Views.
3. From the NAS views, selects File Systems to open the NAS File Systems view.
4. Selects the 10 Most Used File Systems layout, which displays the 10 NAS file
systems that have used the highest percentage of their allocated storage space
Figure 24.
Figure 24 Report listing the 10 most used NAS file systems
The view displays the percentage of storage space used and the number of weeks,
based on usage trends, until the storage space will be completely used.
