Number of WWNs that can be registered for each
storage system
Number of iSCSI names that can be registered
for each storage system
Number of WWNs that can be registered for each
LDEV
Number of iSCSI names that can be registered
for each LDEV
Notes:
1 When the maximum number of LDEVs for a storage system is less than 16,384, the
.
maximum number of LDEVs that can be registered is the maximum number of total
LDEVs for a storage system.
2 The sum of the number of WWNs and the number of iSCSI names. This sum should
.
be a maximum of 2,048 for each storage system.
3 The sum of the number of WWNs and the number of iSCSI names. This sum should
.
be a maximum of 32 for each LDEV.
Note:
• When there are 4,096 or more LDEVs with SPM configured, if you
configure SPM in another LDEV, host I/O response in the LDEV is slower
than the existing LDEVs with SPM configured. To improve the host I/O
response, delete the SPM information in the new LDEV with SPM
configured, then delete the existing SPM information to decrease the
number of LDEVs with SPM configured to 4,095 or fewer, and then
configure SPM in the new LDEV again.
Table 5-6 Priority to be set by specifying a port and a WWN or iSCSI name
of an HBA, and control of server performance
Priority
Non-prioritized Controls server performance based on the upper limit. The upper limit
is set for each non-prioritized WWN or non-prioritized iSCSI name.
The upper limit suppresses the number of accesses from a host bus
adapter to an LDEV, or the amount of data to be transferred.
Monitoring information can be displayed according to the combination
of an LDEV and a WWN or iSCSI name of a host bus adapter.
Prioritized Does not control server performance of a prioritized WWN or prioritized
iSCSI name.
Monitoring information can be displayed according to the combination
of an LDEV and a WWN or iSCSI name of a host bus adapter.
Note: Unlike the case of configuring Server Priority Manager by specifying a
port and a WWN of a host bus adapter, the function for enabling or disabling
control of the upper limit automatically according to the traffic amount is not
supported.
