Other Fault-Management Features

The Smart Array 3200 Controller and the network operating system support
several other fault-management and data-reliability features, including:

■ 

Auto-reliability monitoring

■ 

Dynamic-sector repairing

■ 

Drive-parameter tracking

■ 

Drive-failure alert features

■ 

Interim data recovery

■ 

Automatic data recovery

■ 

Hot-plug drives (Compaq ProLiant Storage System, Compaq ProLiant
Server, Rack-Mountable Compaq ProLiant Storage System or Rack-
Mountable Compaq ProLiant Server)

The following functions are not Smart Array 3200 Controller features, but can
be supported by the operating system:

■ 

Controller duplexing

■ 

Software-based drive mirroring
