Software Operation Manual Chapter 1. INTRODUCTION This chapter provides a brief introduction of RAID Concept and Understanding RAID. 11..11 R RA AIID DC Coonncceepptt 1.1.1 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).
Chapter 1. Introduction 1.1.3 Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used immediately 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. The operating system can instantly access to the newly created arrays without requiring a reboot and waiting the initialization complete.
Software Operation Manual After Array Expansion (Adding One Disk) Free Space = 80GB Volume 1 = 40GB (D: ) Volume 0 = 40GB (C: ) Disk0 40GB Disk1 40GB Disk2 40GB Disk3 40GB Array-A 160GB 1.1.6 Online RAID Level and Stripe Size Migration User can migrate both the RAID level and stripe size of an existing volume set, while the server is online and the volume set is in use.
Chapter 1. Introduction Note The hot spare must have at least the same capacity as the drive it replaces. 1.1.8 Hot-Swap Disk Drive Support The RAID subsystem has built the protection circuit to support the replacement of SAS/SATA hard disk drives without having to shut down or reboot the system. The removable hard drive tray can deliver “hot swappable,” fault -tolerant RAID solutions at prices much less than the cost of conventional SCSI hard disk RAID subsystems.
Software Operation Manual 1.2.1 RAID 0 RAID 0, also referred to as striping, writes stripping of data across multiple disk drives instead of just one disk drive. RAID 0 does not provide any data redundancy, but does offer 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.
Chapter 1. Introduction 1.2.3 RAID 10(1E) RAID 10(1E) is a combination of RAID 0 and RAID 1, combing stripping with disk mirroring. RAID Level 10(1E) combines the fast performance of Level 0 with the data redundancy of Level 1. In this configuration, data is distributed across several disk drives, similar to Level 0, which are a stripe across a number of mirrored sets for data protection.
Software Operation Manual 1.2.4 RAID 3 RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks to all but one drive in the array. The parity data created during the exclusive-or is then written to the last drive in the array.
Chapter 1. Introduction 1.2.6 RAID 6 RAID 6 provides highest reliability, but not widely used. Similar to RAID 5, but does two different parity computations or the same computation on overlapping subsets of the data. The RAID 6 can offer fault tolerance greater that RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data. RAID 6 is an extension of RAID 5 that uses a second independent distributed parity scheme.
Software Operation Manual 1.2.7 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 performance without adding disks to each RAID x array. The operating system uses the spanned volume in the same way as a regular volume. Up to one drive in each sub-volume (RAID 3 or 5) may fail without loss of data. Up to two drives in each sub-volume (RAID 6) may fail without loss of data.
Chapter 1. Introduction 1.2.8 JBOD (Just a Bunch Of Disks) A group of hard disks in a RAID subsystem 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. 1.2.9 Single Disk (Pass-Through Disk) Pass through disk refers to a drive that is not controlled by the RAID firmware and thus can not be a part of a RAID volume. The drive is available to the operating system as an individual disk. 1.2.
Software Operation Manual 5 Also known Block-Interleaved Distributed Parity. Data and parity information is subdivided and distributed across all disk. Parity must be the equal to the smallest disk capacity in the array. Parity information normally stored on a dedicated parity disk. 6 30 50 60 18 RAID 6 provides highest reliability, but not widely used. Similar to RAID 5, but does two different parity computations or the same computation on overlapping subsets of the data.

Software Operation Manual Appendix B. Fibre Operation O Ovveerrvviieew w Fibre Channel is a set of standards under the auspices of ANSI (American National Standards Institute). Fibre Channel combines the best features from SCSI bus and IP protocols into a single standard interface, including high-performance data transfer (up to 800 MB per second), low error rates, multiple connection topologies, scalability, and more.
Appendix B. Fibre Operation Point-to-point A point-to-point topology consists of two and only two devices connected by N_ports of which are connected directly. In this topology, the transmit Fibre of one device connects to the receiver Fibre of the other device and vice versa. The connection is not shared with any other devices. Simplicity and use of the full data transfer rate make this Point-to-point topology an ideal extension to the standard SCSI bus interface.
Software Operation Manual Cables and connectors There are different types of cables of varies lengths for use in a Fibre Channel configuration. Two types of cables are supported: Copper and optical (fiber). Copper cables are used for short distances and transfer data up to 30 meters per link. Fiber cables come in two distinct types: Multi-Mode fiber (MMF) for short distances (up to 2km), and Single-Mode Fiber (SMF) for longer distances (up to 10 kilometers).

Fibre Operation Appendix C PCI-e Raid GUI (for PCI-e only) C Crreeaattee R RA AIID DS Seett FFuunnccttiioonn In Create RAID Set Function user can select RaidSet mode to “Max 128 Volumes” or “Max 16 Volumes”, RaidSet mode that set to “Max 16 Volumes” can compatible with YA series controller.
Software Operation Manual S Syysstteem mC Coonnffiigguurraattiioonn The “System Beeper Setting” function is designed for “Disabled” or“Enabled” the 6Gb/s SAS RAID controller alarm tone. Background Task Priority The “Background Task Priority” is a relative indication of how much time the controller devotes to a rebuild operation. The 6Gb/s SAS RAID controller allows the user to choose the rebuild priority (UltraLow, Low, Medium and High) to balance volume set access and rebuild tasks appropriately.
Appendix B. Fibre Operation HDD Read Ahead Cache Allow Read Ahead (Default: Enabled)—When Enabled, the drive’s read ahead cache algorithm is used, providing maximum performance under most circumstances. Volume Data Read Ahead The volume read data ahead parameter specifies the controller firmware algorithms which process the Read Ahead data blocks from the disk. The Read Ahead parameter is normal by default. To modify the value, you must set it from the command line using the Read Ahead option.
Software Operation Manual Max command Length The "Max command Length" can set from 148K to 4M for performance fine tune. Auto Activate Incomplete Raid When some of the disk drives are removed in power off state or boot up stage, the RAID set state will change to “Incomplete State”. But if a user wants to automatically continue to work while the 6Gb/s SAS RAID controller is powered on, the user can set the “Auto Activate Incomplete Raid” option to enable.
Appendix B. Fibre Operation A Addvvaannccee C Coonnffiigguurraattiioonn TLER Setting TLER (time-limited error recovery) functions provide support for WD Caviar RE (RAID) series disks. This is a new option from WD to support RAID features that were traditionally missing from standard desktop drives. TLER is a method of signaling the system RAID controller in the event that an error recovery process is taking longer than time-out specifications allow.
Software Operation Manual Buffer Threshold Setting There are 4 options in this new feature; 5%, 25%, 50%, 75%. The percentage represents how much data should be kept in resident cache memory (how full cache should get) before controller starts to flush data onto the hard drives. If the buffer is set for 25%, then all 25% will be cached and is used for writing data. The remaining cache memory will be used for reading and other system overhead. Write buffer threshold for 5% is added for video recording.
Appendix B. Fibre Operation Number of AV Stream RAID controllers are required to have not only the function of processing ordinary data but also the function of dealing with AV (audio/video) stream data which needs real-time processing. Since the bus cycle used in RAID controller was designed to transfer the computer data exactly, it was unsuitable for the transfer of AV stream that needs a great band widths. They are required to do some setting for the handshaking during the processing of stream data.
Software Operation Manual Read And Discard Parity Data Determine if parity data is to be read and discarded. If reading block is not in sequence, some HDD will run as random mode, where performance will be decreased, therefore, by enabling Read And Discard Parity Data, data and parity data both will be read and parity data will be discard, reading block will continue and as a result user can get more smoothly performance.
