The following items are displayed in the Main area:
• Host : Bandwidth Limit
- Host
The host name for which the host affinity setting is configured is displayed.
If "All" is displayed, all of the hosts can access the ETERNUS DX Disk storage system.
- Bandwidth Limit
The maximum performance is displayed in IOPS (throughput value). If the bandwidth limit has not
been configured (the bandwidth has not been limited), "Unlimited" is displayed.
If "All" has been selected for hosts, a "-" (hyphen) is displayed.
Click the [Host : Bandwidth Limit] link to display the total performance information for the host and the
performance information of each LUN. Refer to "9.1.13 Host-LU QoS Performance Information" (page 407)
for details.
• Host Group
If a host belongs to a host group, the host group name is displayed. If a host does not belongs to the host
group, a "-" (hyphen) is displayed.
If "All" is displayed, all of the hosts can access the ETERNUS DX Disk storage system.
• The operation status of Host-LU QoS can be confirmed with the displayed action name.
- If [Enable Host-LU QoS] is displayed, the Host-LU QoS has been disabled. Host-LU QoS is not running.
- If [Disable Host-LU QoS] is displayed, the Host-LU QoS has been enabled. Host-LU QoS is running.
• Host-LU QoS starts its operation by configuring the bandwidth limit on a "Host", "CA Port", or "LUN Group",
and enabling the Host-LU QoS.
• This function displays the performance information that is obtained during performance monitoring
regardless of whether the Host-LU QoS mode is enabled or disabled. When the performance information
is displayed before performance monitoring is stopped, the performance information that was obtained
up to this point is displayed. This function displays the total performance information for the host and the
performance information for each host LUN.
• The performance information of each CA port can also be displayed. Refer to "9.1.8.5 Port QoS (Basic)"
(page 396) for details.
