Figure 10 - 1: Selecting Maximum Drive Response
Timeout Value
To prepare the array for read-intensive applications, the following are
recommended:
1. Performance using the write-through caching mode is better than
that using the write-back mode on subsystems equipped with
redundant RAID controllers.
2. Arrays should not be partitioned.
3. The priorities for Rebuild or Add-drive operations should be set to
“low.”
4. Another timeout value, the “Drive I/O Timeout” which
determines whether a drive has eventually failed to respond to I/O
requests, is required as the first-level timeout.
10.2 AV Optimization Mode
The AV optimization is applied for the emerging streaming Audio/Video
applications. This option prepares the array for applications requiring
continuous reading such as video streaming.
