Replacing the Array Accelerator

The Smart Array 3200 Controller has a removable 64-MB Array Accelerator. The Array Accelerator is mounted on a removable daughterboard so it can be easily replaced if necessary. The Smart Array 3200 Controller is not operable without the Array Accelerator.

The Smart Array 3200 Controller Array Accelerator has several unique features:

■It accelerates data storage by temporarily caching the data at high internal bus rates while transferring the data to the drives at their slower Write speeds.

■It uses its own batteries to keep the data alive without board power, even if the Array Accelerator is removed from the Smart Array 3200 Controller.

■The memory is Error Checking and Correcting (ECC), providing error detection and correction reliability.

■It can be moved to another Smart Array 3200 Controller to complete the data transfer should the original Smart Array 3200 Controller fail.
