1-1IntroductionThis chapter will introduce you to your new Disk Array’s features andprovide information on general RAID concept. Chapter 1: “Introduction”
1-2IntroductionThis section provides an overview of the features. For more detailedinformation, please refer to the technical specifications appendixat the end of this manual .Your Disk Array includes the following features : Easy OperationAs everyone knows, conventional Disk Arrays are designed for experienced computer specialists. To solve complicated and timeconsuming operating procedures, we came up with a revolutionaryidea :— Innovative Plug And Play RAID —As compared to a conventional Disk Array’s long-winded setup procedures, your Disk Array can be ready to go after using the simple step by step built-in setup program.Ultra High performanceYour Disk Array combines an extremely high speed microprocessorwith the latest chip set, IDE hardware technology , perfect firmwareand an artistic design. The result is one of the fastest, most reliableDisk Array systems on the market. Supports virtually all popular operating systems, platforms andnetwork environments because it works independently from theO.S. Ultra 160 LVD SCSI channel interface to your Host computer, up to 160MB data transfer rate provides the processing and accesspower for you to handle complex and large files. Selective SCSI ID 0 ~ 14 , support with active termination. Tagged-command queuing : allows processing of up to 255simultaneous data requests.  Selective RAID levels 0, 1, 0+1, 3 or 5 , JBOD. Build-in 64MB cache memory, expandable up to 512MB. Serial communication port ( Terminal Port ) permits array controller operation through a standard VT100 terminal (or equivalent).Features
1-3IntroductionSolid reliability Automatic failed disk drive detection. Auto rebuild : when a replacement disk installed (or by using hot spare disk ), The system provides automatic data rebuildwithout any commands or functions keyed in. ( Transparent toHost )Efficient maintenance An LCD status panel displays a comprehensive readout of the operating status, and the HDD LED indicators on each HDD traydisplay the individual HDD status. When disk failure occurs on a member disk of the disk array, thebuilt-in buzzer sounds simultaneously and LCD status panel alsopoints out the location of the failed hard disk drive. In themeantime the LED HDD status indicator will light up “ Red “onthe failed HDD tray , according the LED indicator on the HDDtray you can perform quick, efficient and correct maintenance. Hot Swap : allows you to remove and install the “ Hot Swap “parts without interrupting data access while the system is on.The “ Hot Swap “ parts include the Hard Disk Drive, RedundantPower Supply Unit and Cooling Fan.
1-4IntroductionCorrect installation of the disk array requires an understanding ofRAID technology and the concepts described in this section.DefinitionRAID is an acronym of Redundant Array of Independent Disks . A RAID is a Disk Array in which part of the storage capacity is usedto record redundant information about the user data stored on the remainder of the storage capacity. The redundant informationenables regeneration of user data in the event that one of the Array’s member Disks or the access path to it fails.Benefits of RAID 1. Secure Data RAID is an emerging storage technology with the potential to revolutionize the data storage technology. A typical RAID unitcontains a set of disk drives, typically two to six, which appear tothe user to be equivalent to a single large capacity disk drive.The remarkable benefit of disk array is that if any single disk in theRAID fails, the system and array still continues to function withoutloss of data. This is possible because the redundancy data isstored on separate disk drives and the RAID can reconstruct the data that was stored on the failed disk drive. 2. Increases system performance As the effective seek time for finding data on a disk can potentially be reduced by allowing multiple simultaneous accessof different data on different disks. Utilizing parallel reads andwrites of the data spread across the disks in the array, the datatransfer rate can be increased significantly over that of a singledisk.3. Easy maintenanceRAID system maintenance is typically simplified because it iseasy to replace individual disks and other components while the system continues to function. ( Hot swap support )General RAID Concepts
1-5IntroductionRAID Level 0 : “ Disk Striping “ High I/O Performance Improved I/O performance is the major reason of using RAID level 0. No protection is provided against data loss due to member disk failures. A RAID level 0 array by itself is thus an unsuitable storage medium for data that can not easily be reproduced, or for data that must be available for critical system operation. It is more suitable for data that can be reproduced or is replicated on other media.A RAID level 0 array can be particularly useful for :Storing program image libraries or runtime libraries for rapidloading, these libraries are normally read only.Storing large tables or other structures of read only data forrapid application access. Like program images, the datashould be backed up on highly reliable media, from which itcan be recreated in the event of a failure.Collecting data from external sources at very high datatransfer rates.  RAID level 0 arrays are not particularly suitable for :Applications which make sequential requests for small amount of data. These applications will spend most of their I/O time waiting for disks to spin, whether or not they use striped arrays as storage media.Applications which make synchronous random requests for small amounts of data. RAID Levels
1-6IntroductionRAID Level 1: “Disk Mirroring” High Data reliabilityRAID level 1 provides both very high data reliability and continueddata availability in the event of a failure of an array member. Whena RAID level 1 member disk fails, array management software simply directs all application requests to the surviving member.RAID level 1 is suitable for data for which reliability requirements areextremely high, or for data to which high performance access isrequired, and for which the cost of storage is a secondary issue.
1-7IntroductionRAID Level 3 :“ Parallel Transfer Disks with Parity “High Data Reliability & Highest Transfer CapacityRAID Level 3 technology use a dedicated parity disk to store redundant information about the data on several data disks. RAIDLevel 3 is an excellent choice for applications which require singlestream I/O with a high data transfer rate.RAID Level 3 is optimal for applications in which large block ofsequential data must be transferred quickly, these applications areusually of one of these types :They operate on large data objects such as graphical image processing, CAD/CAM files, and others.They are non-interactive applications that process large data sequentially.They usually request a large amount of data (32KBytes or more)with each I/O request. The distinctive performance characteristics of RAID Level 3 :RAID Level 3 provides excellent performance for data transfer-intensive applications.RAID level 3 is not well suited for transaction processing or other I/O request-intensive applications.
1-8IntroductionRAID Level 5 :“ Independent Access Array with Rotating Parity “High Data Reliability & Transfer CapacityWhen RAID Level 5 technology is combined with cache memory toimprove its write performance, the result can be used in any applications where general purpose disks would be suitable.For read only or read mostly application I/O loads, RAID Level 5 performance should approximate that of a RAID Level 0 array. Infact, for a given user capacity, RAID Level 5 read performanceshould normally be slightly better because requests are spreadacross one more members than they would be in a RAID Level 0array of equivalent usable capacity.A RAID level 5 array performs best in applications where data and I/O load characteristics match their capabilities :Data whose enhanced availability is worth protecting, but for which the value of full disk mirroring is questionable.High read request rates.Small percentage of writes in I/O load.
1-9IntroductionRAID level 5 arrays have unique performance characteristics :The data can be recalculated or regenerated, using parity, when any drive in the array fails.When the failed drive is replaced, either automatically if the subsystem contained a hot spare drive, or by user intervention during a scheduled maintenance period, the system will be restored its full data redundancy configuration by rebuilding all of the data that had been stored on the failed drive onto the new drive. This is accomplished using parity information and data from the other data disks. Once the rebuild process is complete, all data is again protected from loss due to any failure of a single disk drive.
