Chapter 11. Applications 213 300 IOPS ( assuming an average I/ O service time of 10 ms). Thus, you need to configure a sufficient number of VSCSI HDisks to get the IOPS bandwidth needed. But, at the subject levels, queue_ depth for the VIOC HDisks is configurable up to 256. When possible, set the queue depth of the VIOC HDisks to match that of the VIOS HDisk to which it maps. 11.5.2 Data layout strategies You can use the SVC or AIX LVM ( with appropriate configuration of vscsi disks at the VIOS) to balance the I/ Os across the back- end physical disks. So, here are the options to balance the I/ Os evenly across all arrays on the back- end disk subsystems: When using an SVC: You create just one LUN per array on ...
