  • Page 13: Features

    Chapter 1 Features The Smart Array 3200 Controller is a dual-channel, 32-bit array controller that offers advanced features (see below). The Smart Array 3200 Controller supports Wide-Ultra2 SCSI technology for improved data transfer rates and is backward- compatible with other SCSI devices. It also includes optional daughterboards for customizing combinations of internal and external connections (two external, two internal, or one internal and one external).

  • Page 15: About The Smart Array 3200 Controller

    It provides a high-speed (up to 132 MB/sec) path between the system board and the controller. The Smart Array 3200 Controller is a PCI Bus Master device and conforms to Rev. 2.1 of the PCI Local Bus Specification.

  • Page 16: Using The Array Accelerator

    This data is then read into the array accelerator from the drives. When the Smart Array 3200 Controller receives a read request for the cached data, the data can be brought into the system at memory speeds and avoid the latency of a disk access.

  • Page 181: Recovering From Drive Failure

    The purpose of fault-tolerant configurations on the Smart Array 3200 Controller is to protect against data loss due to drive failure. Although the Smart Array 3200 Controller firmware is designed to protect against normal drive failure, it is imperative that the correct actions are performed to recover from a drive failure without inadvertently inducing any additional drive failures.

    “rebuilding” condition following a drive failure if a spare drive was previously assigned and is being rebuilt. In any RAID 1 logical drive on the Smart Array 3200 Controller tht has N physical drives in the array (not including spare drives), the first N/2 physical drives are normally mirrored in consecutive order to the second N/2 physical drives.
