Write cache without batteries enabled
Whether the write cache is enabled without batteries.
Flush cache after
The maximum amount of time that dirty data (data that has been cached, but not yet written to physical storage for the volume) can be maintained in cache before being flushed to physical storage. The following time specifiers are supported:
  • CACHE_FLUSH_IMMEDIATE - Cached data will be flushed immediately after it is placed in the cache.
  • CACHE_FLUSH_250_MSEC - Cached data will be flushed after 250 milliseconds.
  • CACHE_FLUSH_500_MSEC - Cached data will be flushed after 500 milliseconds.
  • CACHE_FLUSH_750_MSEC - Cached data will be flushed after 750 milliseconds.
  • CACHE_FLUSH_1_SEC - Cached data will be flushed after 1 second.
  • CACHE_FLUSH_1500_MSEC - Cached data will be flushed after 1500 milliseconds (1.5 seconds).
  • CACHE_FLUSH_2_SEC - Cached data will be flushed after 2 seconds.
  • CACHE_FLUSH_5_SEC - Cached data will be flushed after 5 seconds.
  • CACHE_FLUSH_10_SEC - Cached data will be flushed after 10 seconds.
  • CACHE_FLUSH_20_SEC - Cached data will be flushed after 20 seconds.
  • CACHE_FLUSH_60_SEC - Cached data will be flushed after 60 seconds.
  • CACHE_FLUSH_120_SEC - Cached data will be flushed after 120 seconds (2 minutes).
  • CACHE_FLUSH_300_SEC - Cached data will be flushed after 300 seconds (5 minutes).
  • CACHE_FLUSH_1200_SEC - Cached data will be flushed after 1200 seconds (20 minutes).
  • CACHE_FLUSH_3600_SEC - Cached data will be flushed after 3600 seconds (1 hour).
  • CACHE_FLUSH_INFINITE - Cached data is not subject to any age/time constraints; it will be flushed based on other criteria managed by the controller.
