Cache Policy
'Cache Policy' default: write back
Write Back
-
Any data written to the array will be stored as cache, resulting in better I/O
performance at the risk of data failures due to power outages. Data will be stored as cache
before it is physically written to the disk; when a power outage occurs, any data in the
cache will be lost.
Write Through -
Data written to an array is directly written onto the disk, meaning lower
write performance for higher data availability. Without cache acting as a buffer, write
performance will be noticeably slower but data loss due to power outages or other failures
is significantly minimized.
