Simulation results for SANs pages show the utilization of SAN storage I/O, storage space, and SAN connections in the capacity model. This information can help you determine whether you should increase, replace, or reconfigure SAN resources.
The simulation results for SANs pages include:
- Utilization of storage I/O
- Displays information about SAN input and output utilization of disks in a SAN.
- Utilization of storage space
- Displays information about SAN storage space that used by the SAN.
- Utilization of SAN connections
- Displays information about the utilization of SAN interconnects.

| If you think you might have resources that are under-utilized or over-utilized or if you think transactions have unacceptably high latency, see Over-Utilized Resources and High-Latency Transactions. |
You can filter the view of displayed resources by performing the following steps.
To filter the displayed resources-
Click the drop-down icon for a resource title.
-
Click the item you want to filter by. The resource column heading is displayed in bold characters.
| Note |
|---|
| After you apply a filter, you can remove the filter only by selecting the All item. Filters remain in effect when you navigate away from simulation results. This is apparent when you return to view simulation results by the resource column heading displayed in bold characters. |
You can change the sort order of the resources by performing the following step.
To change the sort order of displayed resources-
Click the column heading of the displayed resource.
The following elements can appear in simulation results for clients pages.
- Health
- General health of the resource, indicating whether the
threshold of the resource is at one of the following levels:
- Above the device utilization threshold, indicated by a red X
icon.
- Within 5 percent of the device utilization threshold, indicated
by a yellow exclamation point icon.
- Less than 5 percent of the device utilization threshold,
indicated by a green checkmark icon.
- Above the device utilization threshold, indicated by a red X
icon.
- Site
- Name of the site.
- SAN name
- Name of the SAN.
- Volume
- Name of the disk volumes contained in the SAN.
- Utilization
- Utilization of the resource, in percentage of total utilization.
- Reads (Bytes/s)
- Number of bytes read per second by the device.
- Writes (Bytes/s)
- Number of bytes written per second by the device.
- Reads (IO/s)
- Number of I/Os read per second by the device.
- Writes (IO/s)
- Number of I/Os written per second by the device.
- Device configuration
- Details about the hardware configuration of the device, such as the number of disks in a volume, and the RAID level.
- % Used
- The percentage of storage space used by the disk volume.
- Used (GB)
- The number of gigabytes used by the disk volume.
- From server
- Name of the SAN that connects to the SAN switch.
- To SAN Switch
- Name of the SAN switch that connects to the SAN.
- % Busy (Tx)
- Percentage of bandwidth utilized by the SAN interconnect when the server transmits data to the SAN.
- % Busy (Rx)
- Percentage of bandwidth utilized by the SAN interconnect when the server receives data from the SAN.
- Bandwidth
- Data transfer capacity, or speed, of the SAN interconnect.
