MegaRAID SAS Software User Guide Chapter 2: Introduction to RAID RAID Description Chapter 2 Introduction to RAID This chapter describes Redundant Array of Independent Disks (RAID), RAID functions and benefits, RAID components, RAID levels, and configuration strategies. In addition, it defines the RAID availability concept, and offers tips for configuration planning.
Page 22: Drive Group
Chapter 2: Introduction to RAID Components and Features MegaRAID SAS Software User Guide A drive group is a group of physical drives. These drives are managed in partitions 2.4.1 Drive Group known as virtual drives. A virtual drive is a partition in a drive group that is made up of contiguous data 2.4.2 Virtual Drive segments on the drives.

Page 27: Disk Spanning
MegaRAID SAS Software User Guide Chapter 2: Introduction to RAID Components and Features Disk spanning allows multiple drives to function like one big drive. Spanning 2.4.11 Disk Spanning overcomes lack of disk space and simplifies storage management by combining existing resources or adding relatively inexpensive resources. For example, four 20 GB drives can be combined to appear to the operating system as a single 80 GB drive.
Page 28: Hot Spares
Chapter 2: Introduction to RAID Components and Features MegaRAID SAS Software User Guide NOTE: In a spanned VD (R10, R50, R60) the span numbering starts from Span 0, Span 1, Span 2, and so on. A hot spare is an extra, unused drive that is part of the disk subsystem. It is usually in 2.4.12 Hot Spares standby mode, ready for service if a drive fails.
Page 29: Disk Rebuilds
MegaRAID SAS Software User Guide Chapter 2: Introduction to RAID Components and Features Hot spare drives can be located on any RAID channel. Standby hot spares (not being used in RAID drive group) are polled every 60 seconds at a minimum, and their status made available in the drive group management software.
Page 30: Rebuild Rate
Chapter 2: Introduction to RAID Components and Features MegaRAID SAS Software User Guide The rebuild rate is the percentage of the compute cycles dedicated to rebuilding failed 2.4.14 Rebuild Rate drives. A rebuild rate of 100 percent means that the system gives priority to rebuilding the failed drives.

Chapter 2: Introduction to RAID RAID Levels MegaRAID SAS Software User Guide RAID 0 uses striping to provide high data throughput, especially for large files in an 2.5.1 Summary of RAID Levels environment that does not require fault tolerance. RAID 1 uses mirroring so that data written to one drive is simultaneously written to another drive.

MegaRAID SAS Software User Guide Appendix C: Glossary Appendix C Glossary This appendix provides a glossary for terms used in this document. access policy A virtual drive property indicating what kind of access is allowed for a particular virtual drive. The possible values are Read/Write, Read Only, or Blocked. alarm enabled A controller property that indicates whether the controller’s onboard alarm is enabled.
Page 392 Appendix C: Glossary MegaRAID SAS Software User Guide consistency check An operation that verifies that all stripes in a virtual drive with a redundant RAID level are consistent and that automatically fixes any errors. For RAID 1 drive groups, this operation verifies correct mirrored data for each stripe.
Page 393 MegaRAID SAS Software User Guide Appendix C: Glossary  Unconfigured Bad: A drive on which the firmware detects an unrecoverable error; the drive was Unconfigured Good or the drive could not be initialized.  Missing: A drive that was Online, but which has been removed from its location. ...
Page 394 Appendix C: Glossary MegaRAID SAS Software User Guide initialization The process of writing zeros to the data fields of a virtual drive and, in fault-tolerant RAID levels, generating the corresponding parity to put the virtual drive in a Ready state. Initialization erases all previous data on the drives. Drive groups will work without initializing, but they can fail a consistency check because the parity fields have not been generated.
Page 395 MegaRAID SAS Software User Guide Appendix C: Glossary patrol read A process that checks the drives in a storage configuration for drive errors that could lead to drive failure and lost data. The patrol read operation can find and sometimes fix any potential problem with drives prior to host access.
Page 396 Appendix C: Glossary MegaRAID SAS Software User Guide read policy A controller attribute indicating the current Read Policy mode. In Always Read Ahead mode, the controller reads sequentially ahead of requested data and stores the additional data in cache memory, anticipating that the data will be needed soon. This speeds up reads for sequential data, but there is little improvement when accessing random data.
Page 397 MegaRAID SAS Software User Guide Appendix C: Glossary striping A technique used to write data across all drives in a virtual drive. Each stripe consists of consecutive virtual drive data addresses that are mapped in fixed-size units to each drive in the virtual drive using a sequential pattern. For example, if the virtual drive includes five drives, the stripe writes data to drives one through five without repeating any of the drives.
