Introduction 1-1 Chapter 1 Introduction The RAID subsystem is a Ultra 320 L V D SCSI-to-Seri al A T A II RAID (Redunda nt Arrays of Independent Disks) dis k array subsystem.
Introduction 1-2 1.1 Key Fe ature s Subsystem Features: Features an Intel 80321 64 bit RISC I/O processor Build-in 128MB ca che memory , expa ndable up to 1024MB Ultra 320 L VD host port .
Introduction 1-3 1.2 RAID Conce pts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive.
Introduction 1-4 By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives. This keeps all drives in the array busy during heavy load situations.
Introduction 1-5 RAID 1 , also known as disk mirroring, is simply a pair of disk drives that store duplicate data but appear to the computer as a single drive. Although striping is not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a single large array consisting of pairs of mirrored drives.
Introduction 1-6 RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated to storing parity information. RAID 3 relies on the embedded ECC in each sector for error detection.
Introduction 1-7 RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information to the physical drives in the array. With RAID 6, however, two sets of parity data are used. These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives.
Introduction 1-8 Dual-level RAID achieves a balance between the increased data availability inherent in RAID 1 and RAID 5 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 or RAID 10 and RAID 0+5 or RAID 50.
Introduction 1-9 RAID M a nage ment The subsystem ca n imple ment several different levels of RAID technology . RAID levels supported by the subsystem are shown below. RAID Level Description Min Drives 0 1 3 5 6 0 + 1 Block striping is provide, which yields higher perf ormance tha n with individual drives.
Introduction 1-10 1.3 SCSI Conce pts Before conf iguring the subsystem, you must first understa nd some ba sic SCSI concepts so that the subsystem a nd SCSI devices will function properly. 1.3.1 Multiple SCSI Format Support The subsystem support the SCSI interfa ce sta ndards listed below .
Introduction 1-11 1.3.3 T erminators Ba sed on SCSI specif ications, the SCSI bus must be terminated at both ends, mea ning the devices that are connected to the ends of the SCSI bus must have their bus termin ators enabled. Device s connected in the middle of the SCSI bus must have their terminators disabled.
Introduction 1-12 1.4 Array Definition 1.4.1 RAID Set A RAID Set is a group of disks containing one or more volume sets. It has the following features in the RAID subsystem controller: 1. Up to sixteen RAID Sets are supported per RAID subsystem controller.
Introduction 1-13 1.4.3 Easy of Use features 1.4.3.1 Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used immediately after the creation. But the RAID 3, 5 and 6 volume sets must be initialized to generate the parity.
Introduction 1-14 1.4.3.3 Online Capacity Expansion Online Capacity Expansion makes it possible to add one or more physical drive to a volume set, while the server is in operation, eliminating the need to store and restore after reconfiguring the raid set.
Introduction 1-15 1.4.3.4 Online RAID Level and Stripe Size Migration User ca n migrate both the RAID level and stri pe size of a n existing volume set, while the server is online a nd the volume set is in use.
Introduction 1-16 1.4.4.2 Hot-Swap Disk Drive Support The RAID subsystem has built the protection circuit to support the replace- ment of UDMA hard disk drives without having to shut down or reboot the system.
