HP Write Manager - Administrator Guide
2 HP Disk Cache
HP Disk Cache consolidates the write requests from the operating system to reduce the number of writes
made to the ash drive. This extends the usable life of the ash drive.
To enable HP Disk Cache:
1. In the HP Write Manager Conguration app, select Advanced Cache Settings.
2. Set HP Disk Cache to On.
3. Enter values for the Cache size, Flush count, and Flush interval.
– or –
Select Reset to Defaults.
NOTE: HP has optimized these settings to provide the maximum benet in terms of system
performance and disk longevity.
● Flush count—Sets the number of disk write requests from the operating system to be
consolidated by HP Disk Cache before completing the requests (unless the ush interval is reached
rst). This reduces the number of writes to the ash drive, but it might cause issues if a sudden
power loss occurs when a high number of requests have been stored.
● Flush interval—Sets the amount of time during which HP Disk Cache consolidates disk write
requests from the operating system before completing the requests (unless the ush count is
reached rst). This reduces the number of writes to the ash drive, but it might cause issues if a
sudden power loss occurs when a high number of requests have been stored.
