User Write Cache Setting

This setting enables write caching to improve disk performance, but a power outage or equipment
failure might result in data loss or corruption.

User Cache Power Protection

Some storage controllers provide an option to enable cache power protection. Using a backup
battery, a storage controller can keep data in volatile memory intact, even during power
interruptions. This protects cached data even during power failures.

Drive free space

When drive free space reaches less than 20%, a Warning message displays, with a
recommendation to either move the file to a larger drive or free up more space on the current drive.

Volume mount point

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.

Network page: Viewing and enabling network optimization recommendations

The Network page includes controls for setting network interface NUMA Node, Interrupt, and Port
affinities.

Figure 38 (page 43)

shows an example of a Network.

Figure 38 Network page

The following subsections describe the parameters affecting network optimization.

NUMA node affinity

NUMA (Non Uniform Memory Access) Node is a logical grouping of processors that share common,
directly-linked physical memory. HP ESO recommends CPU NUMA Nodes closest to the network
interface I/O.
