Page 19: Lcd Panel Led Indicators
INTRODUCTION 1.4.2 LCD Panel LED Indicators There are a variety of status conditions that cause the RAID stor- age panel monitoring LED to light. The front panel LCD comes with three (3) status-indicating LEDs. The LEDs on the front panel are defined, from top to bottom, Power, Busy, and Caution, as shown in Figure 1-2.
Page 20: Expansion Connection
INTRODUCTION 1.6 Expansion Connection SAS RAID subsystem is a device that contains one expander port. Expander port may support being attached to SAS initiator ports, SAS and/or SATA target ports, and to other expander ports. The SAS RAID subsystem can connect up to 7 expander enclosures to the host system.
Page 21: Hardware Installation
HARDWARE INSTALLATION 2. Hardware Installation Thanks for purchasing the ARC-8042-12 as your SAS RAID subsys- tem. The following manual gives simple step-by-step instructions for installing and configuring the ARC-8042-12 SAS RAID subsys- tem. Unpack Unpack and install the hardware in a static-free environment. The SAS RAID subsystem is packed inside an anti-static bag between two sponge sheets.
Page 22: Installing Or Removing Drives In The Subsystem
HARDWARE INSTALLATION 2.1 Installing or Removing Drives in the Subsystem Your subsystem supports up to 12 3.5-inch disk drives or 2.5-inch 12Gb/s SAS or 6Gb/s SAS/SATA drives, each one contained in its individual drive carrier. Each drive is hot-pluggable, allowing you to remove and insert drives without shutting down your subsystem.
Page 23: Removing Drives From The Subsystem
HARDWARE INSTALLATION 2. After installing the drive into the drive tray completely, make sure the drive tray latch is open, then slide the drive tray with the attached drive into the subsystem and make sure you latch the drive trays. Figure 2-3, Sliding Drive Tray into Enclosure 2.1.2 Removing Drives from the Subsystem 1.
Page 24: Connecting The Raid Subsystem
The external host connector is provided on the back of the SAS RAID subsystem for connecting the array to server host adapter. The ARC-8042-12 RAID controller has two (2) SFF-8644 SAS IN Port connectors and two (2) SFF-8644 SAS Expansion Port connector.
Page 25: Connecting Monitor Port
LAN port. • Terminal Port Connection Figure 2-6, Terminal Monitor Port Location The ARC-8042-12 SAS RAID subsystem can be configured via a VT-100 compatible terminal or a PC running a VT-100 terminal emulation program. You can attach a serial (Character-Based) terminal or server com port to the SAS JBOD enclosure for access to the text-based setup menu.
Page 26 HARDWARE INSTALLATION SW1-2 SW1-1 Terminal Port Function Expander Terminal Expander Debug Controller Terminal Controller Debug Table 2-1, Terminal Port Function Definition The SAS RAID subsystem package includes one RJ11-to-DB9 serial data cable. Use the RJ11 serial port on the controller module to establish the serial communication link.
Page 27: Power Up The Raid Subsystem
Turning off subsystem power with this switch removes the main power but keeps standby power supplied to the RAID subsystem. Therefore, you must unplug the power cord before subsystem servicing. The installation is completed. You can use your ARC-8042-12 SAS RAID subsystem.
Page 28: Configuring Raid Subsystems
HARDWARE INSTALLATION 2.3 Configuring RAID Subsystems There are often multiple ways to accomplish the same configuration and maintenance tasks for your SAS RAID subsystem. The SAS RAID subsystem is normally delivered with LCD preinstalled. Your SAS RAID subsystem can be configured by using the LCD with keypad, a serial device (terminal emulation) or LAN port.

Page 195 McRAID manager. The key can be escrowed in to a file using McRAID manager. There is one SED key per controller which stores in the controller flash memory. Areca provides both automatically or password methods to generate a key.
Page 196 Step 5. Generate New SED Key If you have evidence that the SED key is known to unauthor¬ized users, you can change the SED key again. Areca provides both au- tomatically or password methods to generate a New key to replace the foreign SED key.
Page 197 APPENDIX Exporting the SED key puts it in a file (SEDKEY256.BIN) that you can then transfer to another computer or put in a safe place. The key file (SEDKEY256.BIN) is stored on the specific location. Without the proper authentication key (SED key), even if the SED RAID set is removed and placed in another new RAID controller, the data remains inaccessible.

Page 200: Raid Concept
APPENDIX Appendix F RAID Concept RAID Set A RAID set is a group of disk containing one or more volume sets. It has the following features in the RAID subsystem. A volume Set must be created either on an existing RAID set or on a group of available individual disks (disks that are not yet a part of an RAID set).
Page 201: Easy Of Use Features
APPENDIX Easy of Use Features • Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used im- mediately after the creation. But the RAID 3 and 5 volume sets must be initialized to generate the parity. In the Normal Initialization, the initialization proceeds as a background task, the volume set is fully accessible for system reads and writes.
Page 202: Online Raid Level And Stripe Size Migration
APPENDIX The RAID subsystem redistributes the original volume set over the original and newly added disks, using the same fault- tolerance configuration. The unused capacity on the expand RAID set can then be used to create an additional volume sets, with a different fault tolerance setting if user need to change.
Page 203: High Availability
APPENDIX High availability Global/Dedicated Hot Spares • A hot spare is an unused online available drive, which is ready for replacing the failure disk. The hot spare is one of the most important features that RAID controllers provide to deliver a high degree of fault-tolerance.
Page 204: Hot-Swap Disk Rebuild
APPENDIX • Hot-Swap Disk Rebuild A Hot-Swap function can be used to rebuild disk drives in ar- rays with data redundancy such as RAID level 1, 10, 3, 5 and 6. If a hot spare is not available, the failed disk drive must be replaced with a new disk drive so that the data on the failed drive can be rebuilt.
Page 205: Raid 1
APPENDIX the best high-speed data throughput. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array. Disk striping en-hances performance because mul- tiple drives are accessed simul-taneously; but the reliability of RAID Level 0 is less than any of its member disk drives due to its lack of redundancy.
Page 206: Raid 10(1E)
APPENDIX • RAID 10(1E) RAID 10(1E) is a combination of RAID 0 and RAID 1, combin- ing stripping with disk mirroring. RAID Level 10(1E) combines the fast performance of Level 0 with the data redundancy of Level 1. In this configura-tion, data is distributed across sev- eral disk drives, similar to Level 0, which are a stripe across a number of mirrored sets for data protection.
Page 207: Raid 5
APPENDIX • RAID 5 RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the controllers rather than concentrated on a dedicated parity disk. If one drive in the system fails, the parity infor- mation can be used to reconstruct the data from that drive.
Page 208: Raid X0
APPENDIX • RAID x0 RAID level-x0 refers to RAID level 30, 50 and 60. RAID x0 is a combination multiple RAID x volume sets with RAID 0 (striping). Striping helps to increase capacity and perfor- mance without adding disks to each RAID x array. The oper- ating system uses the spanned volume in the same way as a regular volume.
Page 209: Jbod
APPENDIX • JBOD (Just a Bunch Of Disks) A group of hard disks in a RAID sub- system are not set up as any type of RAID configuration. All drives are available to the operating system as an individual disk. JBOD does not provide data redundancy. •...

Lower than Reads are Reads are similar Data and parity information is subdivided RAID 1, similar to twice faster than and distributed across all disk. Parity must (10), 6; RAID 0; a single disk; be the equal to the smallest disk capacity in the array.
