    Pre-installation planning Introduction to RAID level The ACS-76500/76510 can support the following RAID level 1+backup. RAID Level 1 supports three disk channels with the “backup” function. It is the function of sequence to turn on and off one disk to be the backup disk in order to keep the data for rebuild when two disks data crash at the same time.

  • Page 14: Raid 1

    Accusys 76500/76510 RAID 1 RAID 1 is commonly referred to as Disk Mirroring, Disk Shadowing or Disk Duplexing as all data is duplicated across both disks. RAID 1 can only be performed with two hard drives (with four drives, RAID 0+1 is configured automatically). As data is identical on both disks, storage capacity is that of the smaller disk.

     Install the RAID box in a system or externally  Load hard drives into ACS-76500/76510 Installation flowchart Installation of ACS-76500/76510 is simple. This chapter will lead you though the following steps:  Use jumpers to set master or slave tatus (only for Configure ACS-76500).

  • Page 18: Setting Configurations

    Setting configurations The master / slave configurations are set manually by placing jumper heads on the nine jumper pins on the rear of the RAID box (Only for ACS-76500). Master and slave settings enable your computer to distinguish two IDE/ATA devices operating on the same channel.

    The hot swap function is available on the RAID 1 array and can be operated during run time. RAID rebuilding will be processed automatically in the background and the ACS-76500/76510 RAID subsystem will record its progress. If the host system is shut down or powered off abnormally, the ACS-76500/76510 RAID subsystem will continue the disk rebuilding process after power is turned on again.

    The status of all indicators during boot-up: Be sure to put three hard disks into the three drive carriers while the ACS-76500/76510 is booting, and lock it before powering on. Then you will see the indicators light up as follows: The green Disk Activity LEDs of the three drive carriers light up except the amber ones.

    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-76500, but the system shows some error messages and the hard drive can’t be accessed normally. Why? The specifications of ACS-76500 are based on ATAPI specifications.
