    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-7630 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 Controller 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.

  • Page 10: Rear View

    The IDE cable is the route used for reading and writing to the array. The power connector supplies power to the controller box. The 3-pin RS-232 cable is used for remote monitoring of ACS-7630. The RS-232 port is configured with DTE and PC compatible pin assignments.

  • Page 11: Chapter 2 - Before You Begin

    Pre-installation planning Introduction to RAID levels The ACS-7630 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

    Accusys 7630 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.

  • 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.

  • Page 14: Pre-Installation Notices

    To avoid overheating, ACS-7630 should be installed in a well-ventilated area and in such a way that sufficient airflow is maintained across the controller chips.

  • Page 16: Setting Configurations

    Accusys 7630 Setting configurations The RAID (level 0 or 5) and master / slave configurations are set manually by placing jumper heads on the nine jumper pins on the rear of the controller box. Master/Slave configuration jumper pins RAID level configuration jumper...

  • Page 17: Master Configuration

    So, if the HDD is configured as the master drive, ACS-7630 should be configured as slave, and vice versa. If using cable select, both devices must use cable select.

  • Page 18: Mounting Controller Box

    Installing controller box externally The ACS-7630 may also be set up outside a computer case and connected to a system via the ACS-2720 IDE to IEEE 1394 converter board. The ACS-2720 (supplied separately) has two ports allowing simultaneous access to the RAID by two hosts.

    Chapter 3 – Setting up the controller Removing a drive from a cable connector drive carrier 1. Unlock the appropriate disk carrier. The red disk activity indicator will light. 2. Slide the drive carrier out of its slot. 3. Lift the disk drive slightly out of the carrier and detach the power and IDE connectors.
  • Page 24 Once ACS-7630 is set up and connected, the array should be initialized. The initialization process is automatic. If system power is off and ACS-7630 is fully set up, simply turn on system power. The system will detect the presence of ACS-7630 and ACS-7630 will check the status of the HDDs.

    Unlock the drive carrier of the failed disk. This will turn off the alarm beep sound. 3. I use a 60cm IDE cable to connect the ACS-7630, but the system shows some error messages and the hard drive can’t be accessed normally. Why? The specifications of ACS-7630 are based on ATAPI specifications.
