Modifying Cache Settings
You can modify the read and write cache settings for an array. You can also modify the MaxIQ
cache settings. The MaxIQ cache uses the MaxIQ-compatible Solid State Drives in your system
as a read cache pool to improve performance in read-intensive applications.
Note:
For more information about MaxIQ, see Using the ACU to Manage the MaxIQ Pool on page
96.
To modify cache settings:
1 Select Manage Arrays from the main ACU menu.
2 Select the array, then press Ctrl+C.
The Modify Cache Settings window opens.
3 Enable or disable read caching.
4 Press Ta b.
5 Select the preferred MaxIQ setting (Enable/Disable), press Ta b, then enable or disable
MaxIQ.
Note:
To enable MaxIQ caching, read caching must also be enabled.
6
Press Ta b.
7 Enable or disable write caching: select Enable always for “write-back” caching; select
Disable for “write-through” caching.
8 Press Enter to accept the values.
Initializing Disk Drives
If a disk drive appears grayed-out (unavailable for use in a new array), it may need to be
initialized.
Option Description
Power Management When enabled, switches the array to low power state, when the array/
drive is inactive.
Slow Down Drive After The duration of inactive state of the array/drive after which it is slowed
down to low power mode. This is an optional setting.
Note: The disk drive should support low power mode.
Power Off Drive After The duration of inactive state of the array/drive after which it is powered
off. This is an optional setting.
Note: Power Off Drive After duration should be greater than Slow
Down Drive After Duration.
Verify Drive After The regular time interval at which the system performs a health check of
the array/drive.
