9.2.7.13 Add LU QoS Group
This function adds LU QoS groups with bandwidth limit (the maximum performance limit) settings to each
host LUN.
The procedure to set the bandwidth limit for host LUN is as follows:
Procedure
1 Click [Add LU QoS Group] in [Action].
• Use one LU QoS group number per 512 Host LUNs as an internal resource. When there are LU QoS groups
with a bandwidth limit other than "Unlimited" from Host LUN#512 onward, the maximum number of QoS
groups cannot be created.
• Host-LU QoS does not support from LUN#1024 onward. Even if volumes are mapped from LUN#1024
onward, only up to 1024 LUNs (LUN#0 - LUN#1023) can be specified for the bandwidth limit.
• This function can be used, irrespective of whether the Host-LU QoS is enabled or disabled.
• By assigning an LU QoS group to a LUN group with the host affinity settings, the bandwidth limit can be
configured for each LUN. Refer to "9.2.7.2 Set Host-LU QoS" (page 599)
for details.
