Chapter 1 Introduction The RAID subsystem is a SAS-to-SAS / SATA II RAID (Redundant Arrays of Independent Disks) disk array subsystem. It consists of a RAID disk array controller and sixteen (16) disk trays. The subsystem is a “Host Independent” RAID subsystem supporting RAID levels 0, 1, 0+1, 3, 5, 6, 30, 50, 60 and JBOD. Regardless of the RAID level the subsystem is configured for, each RAID array consists of a set of disks which to the user appears to be a single large disk capacity.
1.
1.2 RAID Concepts 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. The array of drives appears to the host computer as a single logical drive.
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. This situation allows all drives to work concurrently on different I/O operations, and thus maximize the number of simultaneous I/O operations that can be performed by the array.
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. All writes must go to both drives of a mirrored pair so that the information on the drives is kept identical.
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. In the case of drive failure, data recovery is accomplished by calculating the exclusive OR (XOR) of the information recorded on the remaining drives. Records typically span all drives, which optimizes the disk transfer rate.
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. The main advantages of RAID 6 is High data availability – any two drives can fail without loss of critical data.
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. In summary: ! ! ! ! ! 1-8 RAID 0 is the fastest and most efficient array type but offers no faulttolerance. RAID 0 requires a minimum of two drives. RAID 1 is the best choice for performance-critical, fault-tolerant environments.
RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. Min Drives RAID Level Description 0 Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. 1 1 Drives are paired and mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant. 2 3 Data is striped across several physical drives. Parity protection is used for data redundancy.
1.3 Serial-Attached SCSI (SAS) Overview What is SAS? Serial-Attached SCSI (SAS) is the newest storage interface for Direct-Attached Storage (DAS). SAS is the successor to the highly successful parallel Ultra 320 SCSI interface. SAS improves and expands upon the parallel SCSI technology, and is supported by the ANSI T10 Standards Committee. But why SAS? Performance. Connectivity and scalability. Availability.
Availability In this fast-paced society, data needs to be available to clients whenever they need it. SAS was designed with availability in mind. SAS include the following benefits: Dual ports for redundant controller functionality Support for multiple initiators Hot swappable for easy removal / replacement of the SAS drive 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.
1.4.2 Volume Set A Volume Set is seen by the host system as a single logical device. It is organized in a RAID level with one or more physical disks. RAID level refers to the level of data performance and protection of a Volume Set. A Volume Set capacity can consume all or a portion of the disk capacity available in a RAID Set. Multiple Volume Sets can exist on a group of disks in a RAID Set. Additional Volume Sets created in a specified RAID Set will reside on all the physical disks in the RAID Set.
tion and data on that raid set. If a server fails to work, the raid set disk drives can be moved to another server and inserted in any order. 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. When disks are added to a raid set, unused capacity is added to the end of the raid set.
The RAID subsystem controller 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. 1.4.3.4 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.
1.4.4 High availability 1.4.4.1 Creating Hot Spares A hot spare drive is an unused online available drive, which is ready for replacing the failure disk drive. In a RAID level 1, 0+1, 3, 5, 6, 30, 50 or 60 raid set, any unused online available drive installed but not belonging to a raid set can define as a hot spare drive. Hot spares permit you to replace failed drives without powering down the system.
able rebuild rates. The RAID subsystem will automatically restart the system and the rebuild if the system is shut down or powered off abnormally during a reconstruction procedure condition. When a disk is Hot Swap, although the system is functionally operational, the system may no longer be fault tolerant. Fault tolerance will be lost until the removed drive is replaced and the rebuild operation is completed.
