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.
Accusys 7630 Disk Activity Indicators These indicators show the status of each individual disk drive. Indicator Green Amber Red Red Flashing Disk Activity Disk drive is properly installed and locked Disk drive is being accessed Disk drive is not present, is not properly installed, is unlocked, or disk has failed Disk drive is rebuilding data In the event that a drive fails, the Red indicator turns on and an alarm sounds. You can turn off the alarm by unlocking the drive carrier.
Chapter 2 – Before you begin Chapter 2 B Be effo orre ey yo ou ub be eg giin n This chapter contains includes all the information you need to decide which RAID level to use and to prepare for installation. You will find: A full introduction to and comparison of RAID levels 0 and 5 Important notices on the safe operation and installation of ACS-7630 Pre-installation planning Introduction to RAID levels The ACS-7630 can support the following RAID levels: 0 and 5.
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. 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). RAID 0 offers double or more performance under sustained data transfers when one drive per ATA port is used.
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. 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.
Accusys 7630 Pre-installation notices Before starting any kind of hardware installation, please ensure that all power switches have been turned off and all power cords disconnected to prevent personal injury and damage to the hardware. 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. Static electricity can damage electronic components.
Chapter 3 – Setting up the controller Chapter 3 S Se ettttiin ng gu up p tth he ec co on nttrro olllle err This chapter explains how to: Set RAID level on controller box Set master, slave or cable configuration on controller box Install the RAID controller in a system or externally Load hard drives into ACS-7630 Swap drives Installation flowchart Installation of ACS-7630 is simple.
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 pins RAID 0 configuration 1. Make sure the power is turned off. 2. Make sure the six RAID configuration jumper pins are clear of any jumper caps. RAID 5 configuration 1. Make sure the power is turned off. 2.
Chapter 3 – Setting up the controller Master, slave and cable select settings enable your computer to distinguish two IDE/ATA devices operating on the same channel. In this case, the settings distinguish ACS-7630 from your computer’s hard disk drive. It makes little difference which setting you use, but if using master or slave, you must make sure that the two devices’ settings are different. So, if the HDD is configured as the master drive, ACS-7630 should be configured as slave, and vice versa.
Accusys 7630 Mounting controller box The ACS-7630 controller box can be installed inside a computer case or set up externally. This section describes both procedures. Turn off and disconnect all electrical power from the system before beginning installation. Mounting controller box in system The ACS-7630 controller box fits into the space of two half-height 5¼-inch drive bays. 1. Remove the cover and front bezel from the system case. 2. Feed a power cable opening. 3. Feed a 40-pin IDE cable opening.
Chapter 3 – Setting up the controller Loading drives in the controller box We recommend that you use one of the following hard disk brands: Fujitsu, IBM, Maxtor, Quantum, or Seagate. All three hard disks should be configured as Master. There are two types of drive carrier available: 1. Fixed IDE connector Drive Carrier Fixed IDE Connector Power Connector 2.
Accusys 7630 Fixed connector drive carrier The ACS-7630 should be fitted with three hard disk drives (HDDs). Load each drive into a drive carrier as follows: 1. Unlock the drive carrier and slide it out of the controller box. 2. Place the disk drive in the drive carrier, so that the power and IDE connectors are lined up with the connectors inside the carrier. 3.
Chapter 3 – Setting up the controller Cable connector drive carrier The ACS-7630 should be fitted with three hard disk drives (HDDs). Load each drive into a drive carrier as follows: 1. Unlock the drive carrier and slide it out of the controller box 2. Place the disk drive at an angle in the drive carrier and connect the power connector to the disk drive 3. Carefully connect the drive’s IDE connector to the drive carrier connector. 4.
Accusys 7630 Removing / replacing a drive Swapping drives 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-7630 RAID subsystem will record its progress. If the host system is shut down or powered off abnormally, the ACS-7630 RAID subsystem will continue the disk rebuilding process after power is turned on again. A hard disk should not be replaced when the system is turned off.
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. 4. Lift out the disk drive.
Accusys 7630 Chapter 4 IIn niittiia alliiz ziin ng g tth he ea arrrra ay y 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. Initialization will start. If system power is already on, key off then key on each of the drives in turn.
Chapter 4 – Initializing the array During array initialization, the following will be observed: Indicator Green Status Solid Amber Solid Red Flashing Alarm Intermittent If system power is turned off midway through array initialization, the process will continue from its point of interruption when power returns.
Accusys 7630 Chapter 5 F Fo orrm ma attttiin ng g This chapter explains how to partition and format the array. Partitioning the array The array must be partitioned before it can be used. To do this: 1. Boot to DOS (with bootable floppy disk). 2. Type fdisk. Press Enter. The following screen will appear: 3. When asked Do you wish to enable large disk support (Y/N).........? type Y. Press Enter. 4. The FDISK options menu will appear. Select Change current fixed disk drive. 5.
Chapter 5 – Formatting Take care to ensure that you select the correct drive. Data is destroyed during disk formatting. 6. The screen will return to the FDISK Options menu. Select Create DOS partition or Logical DOS Drive. 7. Select Create Primary DOS Partition. 8. When asked Do you wish to use the maximum available size for a Primary DOS Partition type [Y]. 9. The following message will appear: Primary DOS Partition created, drive letters changed or added. Press Esc to continue. 10.
Accusys 7630 Appendix A F FA AQ Q If you encounter a problem while using the ACS-7630, check this section for help. 1. When I lock a drive carrier with a disk drive in place, the red disk activity indicator turns on and an alarm beep sounds. Why? (a) Make sure you firmly connect the IDE and Power connectors of the HDD to their counterparts inside the drive carrier and try again. If this does not solve the situation, go to (b). (b) Change the disk drive with a new one and try again.
Appendix B – Glossary Appendix B G Gllo os ss sa arry y 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.
Accusys 7630 RAID (Redundant Array of Independent / Inexpensive Disks) A disk array in which part of the storage capacity is used to store redundant information about user data stored on the remainder of the storage capacity. The redundant information enables regeneration of user data in the event that one of the array member disks or the access path to it fails. See Parity. Different RAID levels offer different data throughput speeds and fault tolerance (data redundancy).
