    Hard drive hot swapping Hot Swapping allows for the removal and installation of disk drives without the need to power down the system while ACS-76130 is configured as a RAID 5 array. Automatic drive rebuilding If a member drive in a RAID 5 array is replaced on-line, the controller will automatically start to rebuild data to the new drive.

  • Page 9: Familiarizing Yourself With The Controller

    Chapter 1 – Introduction Familiarizing yourself with the controller Overview The RAID box has three drive carriers, accessed from the front. The sides of the box each feature a guide rail channel and mounting screw holes to enable the box to be secured inside a computer case. The connectors and jumpers are located on the rear panel.

    The power connector supplies power to the RAID box. In order to provide stable power, we recommend to connect both power connectors on the RAID box. The 3-pin RS-232 cable is used for remote monitoring of ACS-76130. The RS-232 port is configured with DTE and PC compatible pin assignments.

    Pre-installation planning Introduction to RAID levels The ACS-76130 can support the following RAID levels: 0 and 5. Which is the right level for you? The answer depends on the application it is used for. RAID Level 0 offers high transfer rates, and is ideal for large blocks of data where speed is of importance.

  • Page 12: Raid 0

    RAID 0 RAID 0 links each drive in the array as one huge drive. Storage capacity is determined by the smallest drive in the array. That capacity is then applied to format all other drives in the array. If using a 40 GB, 60 GB, and 50 GB drive in a RAID 0 array, your system will see one huge drive of 120 GB (40 GB×3).

  • Page 13: Raid 5

    Chapter 2 – Before you begin RAID 5 RAID 5 uses a mathematical expression that compares data from two drives and calculates a third piece of data called “parity”. Should one of the drives fail, parity data can be used to rebuild the failed data.

    The hot swap function is available on the RAID 5 array and can be operated during run time. RAID rebuilding will be processed automatically in the background and the ACS-76130 RAID subsystem will record its progress. If the host system is shut down or powered off abnormally, the ACS-76130 RAID subsystem will continue the disk rebuilding process after power is turned on again.

    Array See Disk Array. Array Management Software The body of software that provides common control and management for a disk array. Array Management Software most often executes in a disk controller or intelligent host bus adapter, but may also execute in a host computer. When it executes in a disk controller or adapter, Array Management Software is often referred to as Firmware.
