Figure 3-10. Controller Properties window, General tab
The General tab has the following properties.
■ System Name—Shows the system name as it is known by the operating
system.
■ Failover Mode—Shows the failover mode selected: high performance
(active/active), high availability (active/passive), or stand-alone (single
controller). High availability is only available with two controllers.
■ Read-ahead cache limit—Enter the desired read-ahead limit (0-16). If
you enter 0, the read-ahead is disabled. Each increment equals 32 blocks
of data that are read ahead in the cache. For example, 2 would equal
64 blocks read ahead.
■ Controller mode—Shows the controller mode, which is active or
unavailable.
■ Rebuild rate—Enter the desired rebuild rate, which ranges from
1 to 100. The controller rebuilds while it handles I/O activity. A rate
below 50 emphasizes I/O response over the RAID rebuild. A rate above
50 puts a higher priority on the RAID rebuild at the expense of I/O
activity.
