RAID Features
5.2.8
Caching
Note:
Intel Integrated RAID software provides write-back cache capability to improve host performance
for certain types of applications. Applications which may benefit from the write-back cache
typically exhibit irregular patterns of write intensity over time. Such applications normally write
short bursts of data. Such applications may include transaction processing (perhaps sorting
applications or accounting software). Also, enabling the write-cache will usually improve
sequential write performance for RAID-5 volumes.
Some applications may incur some performance degradation with the write-cache enabled.
Example applications would include video editing, graphics intensive applications, video
streaming, or other applications which access or copy large files. It is recommended that the user
try both modes of operation (cache enabled and cache disabled) to determine which mode
operation provides the best performance for the applications that are commonly used.
5.2.8.1
Downstream Write-Through (Volume)
The RAID controller cache is used to buffer write data until it is written to disk. Data in the cache
is not available to be read from the cache directly. This type of caching is enabled by default when
no other cache type (Sequential or Full Write Back) is selected.
