For each logical device, you can enable or disable the read cache and write cache of the RAID controller on which the logical device is installed.
Caution! Before you change a cache setting, be sure that you fully understand the implications of the new setting.
Read cache—When read-caching is enabled, the controller monitors read access to the logical device. If it detects a pattern, it pre-loads the cache with the data that seems most likely to be read next.
Write cache—Determines how data is stored in the controller's cache memory. You can choose from two available settings: write-back (enabled) and write-through (disabled)
Note! To improve performance in read-intensive applications, use the maxCache-compatible Solid State Drives (SSDs) in your system as a fast read cache pool. For more information, see Configuring maxCache Read Caching.
To Enable or Disable the Controller Write Cache:
In the Logical Devices View, select a logical device.
In the Actions menu, select Configure write cache, then select Enabled, Enabled (protected by battery/ZMM), or Disabled, as required.
To Enable or Disable the Controller Read Cache:
In the Logical Devices View, select a logical device.
In the Actions menu, select Configure read cache, then select either Enabled or Disabled.
