PAGE 19
3 Understanding RAID concepts Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with how the RAID controllers and operating system view disk space on your system.
PAGE 20
RAID concepts RAID uses particular techniques for writing data to disks. These techniques enable RAID to provide data redundancy or better performance. These techniques include: • Mirroring — Duplicating data from one physical disk to another physical disk. Mirroring provides data redundancy by maintaining two copies of the same data on different physical disks. If one of the disks in the mirror fails, the system can continue to operate using the unaffected disk.
PAGE 21
• Mean Time Between Failure (MTBF) — Using additional disks to maintain data redundancy also increases the chance of disk failure at any given moment. Although this option cannot be avoided in situations where redundant data is a requirement, it does have implications on the workload of the system support staff within your organization. • Volume — Volume refers to a single disk non-RAID virtual disk. You can create volumes using external utilities like the O-ROM .
PAGE 22
• Concatenates n disks as one large virtual disk with a capacity of n disks. • Data fills up the first disk before it is written to the second disk. • No redundant data is stored. When a disk fails, the large virtual disk fails. • No performance gain. • No redundancy. RAID level 0 - striping RAID 0 uses data striping, which is writing data in equal-sized segments across the physical disks. RAID 0 does not provide data redundancy.
PAGE 23
• Data is stored to the disks alternately. • No redundant data is stored. When a disk fails, the large virtual disk fails with no means of rebuilding the data. • Better read and write performance. RAID level 1 - mirroring RAID 1 is the simplest form of maintaining redundant data. In RAID 1, data is mirrored or duplicated on one or more physical disks. If a physical disk fails, data can be rebuilt using the data from the other side of the mirror.
PAGE 24
RAID 5 characteristics: • • • • • Groups n disks as one large virtual disk with a capacity of (n-1) disks. Redundant information (parity) is alternately stored on all disks. When a disk fails, the virtual disk still works, but it is operating in a degraded state. The data is reconstructed from the surviving disks. Better read performance, but slower write performance. Redundancy for protection of data.
PAGE 25
RAID 6 characteristics: • Groups n disks as one large virtual disk with a capacity of (n-2) disks. • Redundant information (parity) is alternately stored on all disks. • The virtual disk remains functional with up to two disk failures. The data is reconstructed from the surviving disks. • Better read performance, but slower write performance. • Increased redundancy for protection of data. • Two disks per span are required for parity. RAID 6 is more expensive in terms of disk space.
PAGE 26
• Requires as much parity information as standard RAID 5. • Data is striped across all spans. RAID 50 is more expensive in terms of disk space. RAID level 60 - striping over RAID 6 sets RAID 60 is striping over more than one span of physical disks that are configured as a RAID 6. For example, a RAID 6 disk group that is implemented with four physical disks and then continues on with a disk group of four more physical disks would be a RAID 60.
PAGE 27
RAID 10 characteristics: • Groups n disks as one large virtual disk with a capacity of (n/2) disks, where n is an even integer. • Mirror images of the data are striped across sets of physical disks. This level provides redundancy through mirroring. • When a disk fails, the virtual disk still works. The data is read from the surviving mirrored disk. • Improved read performance and write performance. • Redundancy for protection of data.
PAGE 28
Comparing RAID Level And Concatenation Performance The following table compares the performance characteristics associated with the more common RAID levels. This table provides general guidelines for choosing a RAID level. Evaluate your specific environment requirements before choosing a RAID level. NOTE: The following table does not show all supported RAID levels in Storage Management. For information on all supported RAID levels in Storage Management, see Choosing RAID Levels And Concatenation. Table 1.
PAGE 29
RAID Level Data Availability Read Performance Write Performance Rebuild Performance Minimum Disks Required Suggested Uses RAID 50 Good Very Good Fair Fair N + 2 (N = at least 4) Medium sized transactional or data intensive uses. RAID 6 Excellent Sequential reads: good. Transactional reads: Very good Fair, unless using writeback cache Poor N + 2 (N = at least two disks) Critical information. Databases and other read intensive transactional uses.

7 Controllers This chapter provides information about the supported controllers and controller features in Storage Management.
PAGE 50
RAID Controller Technology - SATA And SAS Storage Management supports RAID controllers using SATA and SAS technology. This section indicates which technology the supported RAID controllers use. For more information on these controllers, see Supported Features and the controller hardware documentation. SAS RAID Controllers The following RAID controllers use Serial Attached SCSI (SAS) technology.
PAGE 51
Controller — Supported RAID Levels RAID controllers may support different RAID levels. For information on supported RAID levels for a controller, see Supported Features. Controller — Supported Stripe Sizes When creating a virtual disk, you must specify the stripe size for the virtual disk. Different controllers have different limitations on the stripe sizes they can support.
PAGE 52
NOTE: For PERC 10 Controllers ‘Force Write Back’ policy is same as the ‘Write Back’ policy. • Write Back Enabled — The controller firmware disables the write cache if it does not detect the presence of a charged battery over a specified period. For example, on some controllers, the write cache is disabled if the firmware does not detect a charged battery within 72 hours. • Write Through — The controller sends a write-request completion signal only after the data is written to the disk.
PAGE 53
• Unchanged — The disk uses the default write cache mode. NOTE: The Unchanged option is applicable only for PERC 9 hardware controllers with the latest firmware version. NOTE: If you want to revert the Disk Cache Policy settings of the physical disks to the factory default settings, then you must restart the server. The following are the disk cache policy options for RAID disks connected to Software RAID S130 controller: • Default — The disk uses the default write cache mode.

15 Virtual Disks A virtual disk refers to a storage created by a RAID controller from one or more physical disks. Although a virtual disk may be created from several physical disks, it is viewed by the operating system as a single disk. Depending on the RAID level used, the virtual disk may retain redundant data if there is a disk failure or have particular performance attributes. NOTE: Virtual disks can only be created on a RAID controller.
PAGE 132
Considerations Before Creating Virtual Disks Different controllers have particular characteristics in the way they implement virtual disks. These characteristics may include use of disk space, limitations on the number of virtual disks per controller, and so on. It can be helpful to understand these characteristics before creating virtual disks on the controller.
PAGE 133
virtual disk, the controller must decide which free space on the physical disks to allocate to the new virtual disk. The PERC controllers look for the largest area of free space and allocate this space to the new virtual disk. • SCSI limitation of 2TB — Virtual disks created on a PERC controller cannot be created from physical disks with an aggregate size greater than 2TB. This is a limitation of the controller implementation.
PAGE 134
NOTE: On software RAID S110 and S130 controllers, if a physical disk (SATA SSD or HDD) is removed from a virtual disk and the same physical disk is reinserted (hot plug) into the virtual disk instantly, within a fraction of a second, then the virtual disk state is displayed as Ready and the physical disk state is displayed as Online. However, if the same physical disk is reinserted after a short delay, then the virtual disk state is displayed as Degraded and the physical disk state is displayed as Ready.

Virtual disk bad blocks are discovered when the controller performs any operation that requires scanning the disk. Examples of operations that may result in this alert are: • Consistency check • Rebuild • Virtual disk format • I/O • Patrol Read Recovering a physical disk bad block depends on the RAID level and state of the virtual disk. If a virtual disk is redundant, the controller can recover a bad block on a physical disk.
PAGE 139
Recommendations For Clearing Bad Blocks Storage Management allows you to clear the bad block warnings. To clear bad blocks, the following procedure is recommended: 1 Perform a backup of the virtual disk with the Verify option selected. One of the following scenarios may occur: • Backup operation fails on one or more files. In this case, restore the file from a previous backup. After restoring the file, proceed to step 2. • Backup operation completes without error.
