Page 25: Cabling
Chapter 2 – Installation Cabling In its basic configuration (without the addition of an optional daughterboard), ACS-99100 supports up to four SCSI channels (the location of connectors for each channel is shown in the Rear View section of Chapter 1). Each controller channel supports up to 15 device drives.
Page 26 ACS-99100 User’s Manual 2. Connect a SCSI cable from the host system SCSI card to the SCSI host connector on the backplane. 3. Connect the combo cable to the connector on the backplane. The notch on the combo cable connector should be aligned with the corresponding slot on the backplane connector to ensure correct insertion.
Page 27: Turning On For The First Time
Chapter 2 – Installation Turning on for the first time When cabling is complete, ACS-99100 can be turned on. This should be done in the following order: 1. First turn on the power source 2. Then boot the host computer(s) When ACS-99100 is running, you are ready to configure one or more arrays.
Page 28: Chapter 3-Quick Setup
Use of the Monitor Utility requires a connection to be established first between the host terminal (which should have third party communication software supporting ANSI terminal emulation) and ACS-99100. Alternatively, the Monitor Utility can be accessed from a dedicated ANSI terminal.

Chapter 5 – Configuration Updating the Firmware ACS-99100 is shipped with firmware installed. The user may however wish to download new or upgraded editions of the firmware to the controller. Ask your vendor about the latest firmware edition or refer to the website www.accusys.com.tw A terminal emulation program, such as HyperTerminal, is required to download firmware.

Page 67: Appendix A-Troubleshooting
Unable to access ACS-99100 after the operating system boots up. Possible Cause: ACS-99100 is not configured. Fix: Make sure ACS-99100 is configured for a RAID level. If no RAID level is configured the operating system will not detect ACS-99100 as a disk drive.
Page 68 Parity, and None Flow control. Make sure the terminal is configured for these settings. If the settings were changed in Configuration Mode, verify the settings of the ACS-99100 in the RS-232 Params, Terminal option and change the terminal settings accordingly.
Page 69: Appendix B-Introduction To Raid Levels
Appendix B – Introduction to RAID levels The ACS-99100 can support the following RAID levels: 0, 1, 3, 5 ,0+1 ,30 ,50 and NRAID. Which is the right level for you? The answer depends on the application you use your RAID for.
Page 70: Raid 0
ACS-99100 User’s Manual 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 71: Raid 1
Appendix B – Introduction to RAID levels RAID 1 RAID 1 is commonly referred to as Disk Mirroring, Disk Shadowing or Disk Duplexing as all data is duplicated across all disks. As data is identical on all disks, storage capacity is that of the smaller disk.
Page 72: Raid 0+1
ACS-99100 User’s Manual RAID 0+1 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).
Page 73: Raid 3
Appendix B – Introduction to RAID levels RAID 3 RAID 3 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 74: Raid 5
ACS-99100 User’s Manual 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. 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.
Page 75: Raid 30
Appendix B – Introduction to RAID levels RAID 30 RAID 30 arrays are formed by striping data across RAID 3 sub-arrays. They offer better performance than RAID 3 alone but do not have the speed of a pure RAID 0 array. Storage efficiency and fault tolerance vary depending on the number and size of sub-arrays compared to the array as a whole.
Page 76: Raid 50
ACS-99100 User’s Manual RAID 50 RAID 50 arrays are formed by striping data across RAID 5 sub-arrays. They offer better performance than RAID 5 alone, particularly in write speed, but do not have the speed of a pure RAID 0 array. Storage efficiency and fault tolerance vary depending on the number and size of sub-arrays compared to the array as a whole.
Page 77: Nraid
Appendix B – Introduction to RAID levels NRAID NRAID (“Non-RAID”) , the capacity of all the drives is combined to become one logical drive (no block striping). That is to say, the capacity of the logical drive is the total capacity of the physical drives.
Page 78: Appendix C-Optional Components
ACS-99100 User’s Manual The addition of an optional proprietary daughterboard to the ACS-99100 RAID Controller increases the number of channels available and provides extra features. SCSI daughterboard ACS-7485 ACS-7485 adds an extra two SCSI channels to the RAID controller. Fibre daughterboard ACS-7145...
Page 79: Removing / Replacing Daughterboard
Appendix C – Optional Components ACS-5160 requires a separate power cable as indicated. The bridge board links to the host(s) through a small form-factor pluggable (SFP) cable (a separate cable is required for each of the two host channels) The bridge board links to the daughterboard with HSSDC2 cables.
