To ensure that at least some IOPS and bandwidth is available to all the volumes under this rule, HP 3PAR Priority Optimization enforces a minimum value for the I/O limit of 1000 IOs/sec and 100,000 KBs/sec for the bandwidth limit, although these limits may - HP 3PAR StoreServ 7400 2-node | HP 3PAR Command Line Interface Administrator& - Page 158

This command is integrated in HP 3PAR System Reporter (SR) on the 3PAR nodes. SR 3.1 MU1, installed on a separate server, includes statistics on QoS. To learn more about the QoS information in SR, see the HP 3PAR System Reporter 3.1 Software User's Guide and the HP 3PAR System Reporter 3.1 Software - HP 3PAR StoreServ 7400 2-node | HP 3PAR Command Line Interface Administrator& - Page 160

the array to process an I/O request. On HP 3PAR StoreServ Storage systems, response time may be reported as "service time." Response time is measured in milliseconds. Microsoft Exchange Server is a scalable, commercial mail server that supports thousands of users per instance. As a general practice, - HP 3PAR StoreServ 7400 2-node | HP 3PAR Command Line Interface Administrator& - Page 163
of a particular group of users, enhances the performance stability for mail databases for other users and for other applications on the HP 3PAR StoreServ Storage systems. Microsoft Exchange is a highly interactive software, and its users demand a swift response to mouse clicks in the Outlook client - HP 3PAR StoreServ 7400 2-node | HP 3PAR Command Line Interface Administrator& - Page 164
