and increases storage subsystem reliability. 2.3 RAID Functions Virtual drives are drive groups or spanned drive groups that are available to the operating system. The storage space in a virtual drive is spread across all of the drives in the drive group. MegaRAID SAS Software User Guide 2-1 - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 34
drives in a drive group and they must be able to support the RAID level that you select. Below are some common RAID functions: • Creating hot spare drives • Configuring drive groups and virtual drives • Initializing one or more virtual drives • Accessing controllers, virtual drives, and drives - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 35
, this means that it is also important for the system to be available during the repair of the problem. A hot spare is an unused drive that, in case of a disk failure in a redundant RAID drive group, can be used to rebuild the data and reestablish redundancy. After the hot spare is automatically - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 36
data automatically rebuilt by "hot-swapping" the drive in the same drive bay. The RAID drive group continues to handle requests while the rebuild occurs. 2.4.4.1 Multipathing The firmware provides support for detecting and using multiple paths from the RAID controllers to the SAS devices that are - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 37
. Copyback is often used to create or restore a specific physical configuration for a drive group (for example, a specific arrangement of drive group members on the device I/O buses). Copyback can be run automatically or manually. Typically, when a drive fails or is expected to fail, the data is - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 38

It is recommended that you keep stripe sizes the same across RAID drive groups. For example, in a four-disk system using only disk striping (used in RAID - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 40
a stripe width of four. 2.4.9.2 Stripe Size The stripe size is the length of the interleaved data segments that the RAID controller writes across multiple drives, not including parity drives. For example, consider a stripe that contains 64 KB of disk space and has 16 KB of data residing on each - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 41
data so that it can survive up to two drive failures.

and improves performance by doubling the number of spindles. 2.4.12.1 Spanning for RAID 00, RAID 10, RAID 50, and RAID 60 Table 2.2 describes how to configure RAID 00, RAID 10, RAID 50, and RAID 60 by spanning. The virtual drives must have the same stripe size and the maximum number of spans is - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 43
the controller. RAID 10 supports a maximum of eight spans. You must use an even number of drives in each RAID virtual drive in the span. The RAID 1 virtual drives must have the same stripe size. Configure RAID 50 by spanning two contiguous RAID 5 virtual drives. The RAID 5 virtual drives must have - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 44
the following parameters when using hot spares: • Hot spares are used only in drive groups with redundancy: RAID levels 1, 5, 6, 10, 50, and 60. • A hot spare connected to a specific RAID controller can be used to rebuild a drive that is connected to the same controller only. 2-12 Introduction to - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 45
BIOS or use drive group management software to place it in the hot spare pool. • A hot spare must have free space equal to or greater than the drive it replaces. For example, to replace an 18 GB drive, the hot spare must be 18 GB or larger. 2.4.14 Disk Rebuilds When a drive in a RAID drive - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 46
will not start if you replace a drive during a RAID-level migration. The rebuild must be started manually after the expansion or migration procedure is complete. 2.4.15 Rebuild Rate The rebuild rate is the percentage of the compute cycles dedicated to rebuilding failed drives. A rebuild rate of 100 - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 47
is offline. The operating condition in a RAID 6 virtual drive is not optimal. One of the configured drives has failed or is offline. RAID 6 can tolerate up to two drive failures. The virtual drive has failed. The virtual drive is not available to the RAID controller. Components and Features 2-15 - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 48
tolerance of the disk subsystem. 2.5 RAID Levels The RAID controller supports RAID levels 0, 00, 1, 5, 6, 10, 50, and 60. The supported RAID levels are summarized in the following section. In addition, it supports independent drives (configured as RAID 0 and RAID 00.) The following sections describe - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 49
request rates, high data transfers, and medium-to-large capacity. Note: Having virtual drives of different RAID levels, such as RAID 0 and RAID 5, in the same drive group is not allowed. For example, if an existing RAID 5 virtual drive is created out of partial space in an array, the next virtual - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 50
size of each data segment is determined by the stripe size. RAID 0 offers high bandwidth. Note: RAID level 0 is not fault tolerant. If a drive in a RAID 0 drive group fails, the whole virtual drive (all drives associated with the virtual drive) will fail. By breaking up a large file into smaller - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 51
2.5.4 RAID 1 In RAID 1, the RAID controller duplicates all data from one drive to a second drive in the drive group. RAID 1 supports an even number of drives from 2 to 32 in a single span. RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity. Table - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 52
for large files. Use RAID 5 for transaction processing applications because each drive can read and write independently. If a drive fails, the RAID controller uses the parity drive to recreate all missing information. Use also for office automation and online customer service that requires fault - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 53
time. The controller rebuilds one failed drive, and then the other failed drive. Table 2.6 provides a graphic example of a RAID 6 drive group.

Use - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 54
level 00 is not fault tolerant. If a drive in a RAID 0 drive group fails, the whole virtual drive (all drives associated with the virtual drive) will fail. By breaking up a large file into smaller segments, the RAID controller can use both SAS drives and SATA drives to read or write the file faster - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 55
each failure is in a separate drive group. If there are drive failures, less than total drive capacity is available. Configure RAID 10 by spanning two contiguous RAID 1 virtual drives, up to the maximum number of supported devices for the controller. RAID 10 supports a maximum of eight spans, with - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 56
, such as the type of controller, can restrict the number of drives supported by RAID 10 virtual drives. Table 2.10 provides an overview of RAID 10.

. Requires 2 to 8 times as many parity drives as RAID 5. Eight spans of RAID 5 drive groups containing 3-32 drives each (limited by the maximum number of devices supported by the controller) Figure 2.11 RAID 50 Level Virtual Drive RAID 50 Segment 1 Segment 2 (Segment 1,2) Segment 3 Segment - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 58
multiple drive groups. RAID 6 supports two independent parity blocks per stripe. A RAID 60 virtual drive can survive the loss of two drives in each of the RAID 6 sets without losing data. RAID 60 is best implemented on two RAID 6 drive groups with data striped across both drive groups. RAID 60 - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 59
two parity blocks per stripe. A minimum of 8 Figure 2.12 shows a RAID 6 data layout. The second set of parity drives are denoted by Q. The P drives follow the RAID 5 parity scheme.

fails. After the hot spare is automatically moved into the RAID drive group, the failed drive is automatically rebuilt on the spare drive. The RAID drive group continues to handle requests while the rebuild occurs. A hot swap is the manual substitution of a replacement unit in a disk subsystem for - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 61
redundancy using distributed parity across spanned RAID 6 drive groups. RAID 60 can sustain two drive failures per RAID 6 drive group and still maintain data integrity. It provides the highest level of protection against drive failures of all of the RAID levels. RAID 60 includes both parity and - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 62
generation can slow the write process, making write performance significantly lower for RAID 5 than for RAID 0 or RAID 1. Drive performance is reduced when a drive is being rebuilt. Clustering can also reduce drive performance. Environments with few processes do not perform as well because the - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 63
.) As the storage space in the spans is filled, the system stripes data over fewer and fewer spans and RAID performance degrades to that of a RAID 1 or RAID 5 drive group. 60 RAID 60 works best when used with data that requires high reliability, high request rates, and high data transfer. It - Lenovo ThinkServer RD240 | MegaRAID SAS Software User Guide - Page 64
helps you maintain data availability and avoid downtime for the servers that provide that data.
