50 Auto LUN/Performance Control Base Monitor for the XP128/XP1024
• Current: Current I/O or transfer rate.
• Ave.: Average I/O or transfer rate for the specified period.
• Max.: Maximum I/O or transfer rate for the specified period.
• Response Time: Time between when the DKC receives the read/write command and when the DKC
responds to the command. The value is average response time over one minute.
• Attribute: Priority of each host bus adapter. Prio. indicates a high-priority HBA (prioritized WWN).
Non-Prio. indicates a low-priority HBA (non-prioritized WWN). iSCSI ports are always prioritized
ports. Therefore, the Attribute column displays Prio. for each iSCSI port. When calculating I/O rates
displayed in the All Prio. row, Auto LUN uses I/O rates of iSCSI ports and other prioritized ports.
