Simulation Results - Servers

  • Article

Simulation results for servers pages show the utilization of all hardware resources for each server in the capacity model. The simulation results for servers pages include:

  • Utilization of CPU
    Displays the processor utilization for all servers in the capacity model.
  • Utilization of storage I/O
    Displays the storage input and output utilization for all servers in the capacity model.
  • Utilization of storage space
    Displays the storage space utilization for all servers in the capacity model.
  • Utilization of LAN connections
    Displays the LAN connection utilization for all servers in the capacity model.
  • Utilization of SAN connections
    Displays the SAN connection utilization from servers to their SAN switch for all servers connected to a SAN in the capacity model.

Note

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

  1. Click the drop-down icon for a resource title.

  2. 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 servers 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.
  • Site
    Name of the site.
  • Server
    Name of the server.
  • Device
    Name of the hardware resource.
  • % Used
    For storage space, the percentage of storage space used by the storage device.
  • Used (GB)
    For storage space, the number of gigabytes used by the storage space.
  • From server
    Name of the server that connects to a LAN switch.
  • To LAN switch
    Name of the LAN switch that connects to the From server.
  • % 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, measured in GB/sec.
  • 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 Type
    Type of device of the hardware resource.
  • Device Configuration
    Details about the hardware configuration of the device.
