User’s Manual About This document This document discusses how to properly design your RAID solution when using the ACS-77100 RAID controller, and guides you to configure the RAID controller. Customer should have a working knowledge of RAID planning and data storage.
User’s Manual 1. Introduction to the ACS-77100 1.1. Overview The ACS-77100 RAID controller provides RAID 0 (striping), RAID 10 (Striping and mirroring) and RAID 5 (striping with parity) for you to construct a disk array optimized for performance or reliability. By connecting the SATA cables between the ACS-77100 and the disks, a RAID solution can be easily built.
User’s Manual 1.3. Understanding RAID Levels 1.3.1. RAID 0 (striping) RAID 0 links each drive in the array to from one large drive. Storage capacity is determined by the smallest drive in the array. This capacity is then applied to format all other drive in the array. When using a 40GB, 50GB and a 60GB drive in a RAID 0 array, your system will have, in effect, one 120GB drive (40GB x 3) The diagram above represents the writing of data on a RAID 0 array composed of four disks connected to the controller.
User’s Manual 1.3.2. RAID 10 (striping and mirroring) RAID 0+1 combines mirroring and striping functions on a minimum of four hard disks. Mirroring provides full redundancy and protects data in case of multiple drive failure (providing that data on one of each mirrored pair of drives is intact). The diagram shown represents the writing of data on a RAID 0+1 array composed of four DISKS connected to the controller.
User’s Manual 1.3.3. RAID 5 (striping with parity) and RAID 5+hot spare RAID 5 uses a mathematical expression that compares data from three drives and calculates a fourth piece of data called “parity” which is saved on a fourth drive. Should one of the drives failed, parity data can be used to rebuild the failed data. Under RAID 5, parity data is stored across all drives in the array. This maximizes the amount of storage capacity available from all drives in the array while still providing data redundancy.
User’s Manual 2. Build a RAID Solution This chapter covers the installation of the ACS-77100. The customers will be guided to using ACS-77100 to build a RAID solution. 2.1. Hardware Requirement: ACS-77100 RAID controller Backplane or Disk I/O board Disk carriers (with LED Indicators) Power supply Fan module Chassis Other materials SATA disk cable Header to DB9 cable SATA to eSATA internal cable Selector (with header connector + cable) http://www.accusys.com.

User’s Manual 3. Set up the RAID solution This chapter covers the configuration of the ACS-77100. Through an easy process, the customers will be guided to configure the ACS-77100 through the following steps: Step 1 3.1. Setting the RAID level – The ACS-77100 is per-configured at RAID level 5, but you have the option of customizing your RAID level in this step Step 2 3.2. Creating an Array – The disks in ACS-77100 will be used to create an array, by which you can partition and use the storage.
User’s Manual 3.1.1 RAID Level configurations RAID Level 5 RAID Level 0 Pin1-3 is open. Pin1-3 is short. Pin5-7 is open. Pin5-7 is short. RAID Level 10 RAID Level 5 + spare Pin1-3 is short. Pin1-3 is open. Pin5-7 is open. Pin5-7 is short. Note If the RAID level is not matched between the disk setting and the RAID level selector setting, the LCD will display the following two messages alternatively: (1) “RAID level” “Unmatched” (2) “Current: R(X)” (i.e.
User’s Manual 3.2. Creating an Array 3.2.1 Enable/Disable Over 2TB capacity ACS-77100 supports over 2TB capacity. The steps below will guide you to enable/disable over 2TB capacity. 1. Select scroll button to find the capacity setting item on LCD panel. (P.18, 4.1.2. Set over 2TB capacity Messages ) 2. Press the ENT button, and select (YES) or (NO) by the scroll buttons. Note If you want to create the array with over 2TB capacity, the setting must be finished before to create an array. 3.
User’s Manual Note The device over 2TB capacity should be supported by Operation System (e.g. Windows Vista). Please refer to section 3.5. Formatting and Partitioning the ACS-77100 to partition the device. 3.3. Setting the Time and Date by LCD To change the time and date on the LCD, press and hold the ENT button for five seconds. Release the button to display the date and time setting screen. To adjust the time and date values, use the Scroll buttons to change the values. (Figure 3.3.
User’s Manual 3.4. Connecting ACS-77100 to the Host computer 1. Follow the steps on page 11, 3.1. Setting the RAID Level and 13, 3.2. Create an Array to establish a RAID. 2. Connect an end of the eSATA cable into the eSATA port on the ACS-77100 RAID subsystem. 3. Connect the other end of the eSATA cable into the eSATA port on the host computer. It will take a few seconds for the host computer to recognize the drive for it to appear in My Computer or on the desktop.

User’s Manual 6. Trouble Shooting Problem Possible solution The ACS-77100 does Ensure that the array has completed the initialization process. not appear in the BIOS. How should I react to For a RAID 5/RAID 10 array, you should replace the failed disk. disk failure? Data rebuilding will then begin. For a RAID 5+hot spare array, data will be rebuilt automatically to the hot-spare disk. There is no need to immediately replace the failed drive.
User’s Manual 7. FAQ If you encounter a problem while using the RAID box, check this section for help. 1. I have connected the ACS-77100 to host computer, but the host computer cannot recognize the ACS-77100 in BIOS. The array of the ACS-77100 must be created so that the host computer can recognize the RAID in BIOS. Please make sure that an array is created. 2. My Operating System is Linux. I have enabled the over 2TB capacity setting, but I still cannot partition a device over 2TB in OS.
