In a heterogeneous environment, what is a recommended setting when multiple storage arrays are connected...

In a heterogeneous environment where multiple storage arrays are connected to VMware vSphere along with XtremIO X2, it is recommended to set the Disk.SchedNumReqOustanding parameter to 32. This setting determines the maximum number of I/O operations that can be queued to the storage array. A value of 32 is often recommended to balance performance with resource utilization.

The Disk.SchedNumReqOustanding parameter is part of the VMware vSphere’s advanced settings and can be adjusted to optimize the performance of the storage arrays connected to the ESXi hosts. The setting of 32 is a starting point and may need to be adjusted based on the specific workload and storage array capabilities1.
