Volume mount point

This parameter is for information purposes only; it is not settable using HP ESO. Volume mount

points are specialized file system objects which are used to mount and provide an entry point to

other volumes. Mount points can be created in a directory on a file system, which gives a reference

to the root directory of the mounted volume. HP ESO will show all mount points on disk with volume

mount point configured.

Drive Latency

Drive latency (often called rotational latency, rotational delay, or simply latency) is the delay waiting

for the rotation of the disk to bring the required disk sector under the read-write head. The latency

is a function of the rotational speed of the disk (or spindle motor). The latency can be improved

by increasing the rotational speed of the disks. This can also improve throughput.

Network page: Viewing and controlling network parameters and optimization

recommendations

The Network page includes controls for setting various network affinity features, including network

interface NUMA node and port affinities, Receive-Side Scaling (RSS) parameters, and Interrupt

policies. The page is divided into major sections: the NUMA Node Affinity and Interrupt Policy

section and the Port Affinity section. Figure 49 (page 60) shows an example of a portion of the

Network page (the Port Affinity section is not visible; it is below the NUMA Node Affinity and

Interrupt Policy section.

Figure 49 Network page

The following subsections describe the parameters affecting network optimization.

NUMA Node Affinity and Interrupt Policy

The Numa Node Affinity and Interrupt Policy section of the Network page allows you to select

NUMA Node affinity and Interrupt Policy settings. HP ESO detects all NIC adapters connected to

the system. Each tab in this section displays the status of a NIC adapter. Figure 50 (page 61)

shows the NUMA Node and Interrupt Policy parameter settings for a particular network interface:
