Page 25: Overview
Chapter 1 Overview This guide documents the utilities used to configure, monitor, and ® maintain MegaRAID Serial-attached SCSI (SAS) RAID controllers with RAID control capabilities and the storage-related devices connected to them. This guide explains how to use the MegaRAID Storage Manager™ software, WebBIOS, and Command Line Interface (CLI).
Page 26 SAS RAID controllers address the growing demand for increased data throughput and scalability requirements across midrange and enterprise- class server platforms. Lenovo offers a family of MegaRAID SAS RAID controllers addressing the needs for both internal and external solutions. The SAS controllers support the ANSI Serial Attached SCSI standard, version 1.1.
Page 27: Serial-Attached Scsi Device Interface
Serial-attached SCSI Device Interface SAS is a serial, point-to-point, enterprise-level device interface that leverages the proven SCSI protocol set. SAS is a convergence of the advantages of SATA II, SCSI, and Fibre Channel, and is the future mainstay of the enterprise and high-end workstation storage markets. SAS offers a higher bandwidth per pin than parallel SCSI, and it improves signal and data integrity.
Page 28: Solid State Drive Features
• Eliminates the master-slave construction used in parallel ATA • Allows addressing of multiple SATA II targets through an expander • Allows multiple initiators to address a single target (in a fail-over configuration) through an expander Solid State Drive Features MegaRAID firmware supports SSD drives attached to MegaRAID SAS controllers.
Page 29: Dimmer Switch Feature
automatically copying data from a drive with potential to fail to a designated hot spare or newly inserted drive. Because SSDs are very reliable, non-redundant RAID 0 configurations are much more common than in the past. SSD Guard offers added data protection for RAID 0 configurations.
Page 30: Configuration Scenarios
UEFI 2.0 provides MegaRAID customers with expanded platform support. The MegaRAID UEFI 2.0 driver, a boot service device driver, handles block IO requests and SCSI pass-through commands (SPT), and offers the ability to launch pre-boot MegaRAID management applications through a driver configuration protocol (DCP). The UEFI driver also supports driver diagnostic protocol, which allows administrators to access pre-boot diagnostics.

Page 32: Valid Drive Mix Configurations With Hdds And Ssds
1.7.1 Valid Drive Mix Configurations with HDDs and SSDs You can allow a virtual drive to consist of both SSDs and HDDs. For virtual drives that have both SSDs and HDDs, you can choose whether to mix SAS drives and SATA drives on the SSD devices. You can choose whether to allow a virtual drive to consist of both SSD devices and HDDs.
Page 33: Introduction To Raid
Chapter 2 Introduction to RAID This chapter describes RAID (Redundant Array of Independent Disks), 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. RAID Description RAID is an array, or group of multiple independent physical drives that provide high performance and fault tolerance.
Page 34: Components And Features
Your drives must be organized into virtual 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 •...
Page 35: Raid Drive Group
2.4.3 RAID Drive Group A RAID drive group is one or more drives controlled by the RAID controller. 2.4.4 Fault Tolerance Fault tolerance is the capability of the subsystem to undergo a drive failure or failures without compromising data integrity, and processing capability.
Page 36 Auto-rebuild allows a failed drive to be replaced and the 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 in enclosures.
Page 37: Consistency Check
not stop. The controller uses different paths to balance the load on the entire system. In the MegaRAID Storage Manager utility, when multiple paths are available to a drive, the drive information will show only one enclosure. The utility shows that a redundant path is available to a drive. All drives with a redundant path display this information.
Page 38: Background Initialization
Note: During a copyback operation, if the drive group involved in the copyback is deleted because of a virtual drive deletion, the destination drive reverts to an Unconfigured Good state or hot spare state. Order of Precedence – In the following scenarios, rebuild takes precedence over the copyback operation: 1.
Page 39: Patrol Read
2.4.8 Patrol Read Patrol read involves the review of your system for possible drive errors that could lead to drive failure and then action to correct errors. The goal is to protect data integrity by detecting drive failure before the failure can damage data.
Page 40: 2.4.10 Disk Mirroring
2.4.9.1 Stripe Width Stripe width is the number of drives involved in a drive group where striping is implemented. For example, a four-disk drive group with disk striping has 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.
Page 41: 2.4.11 Parity
2.4.11 Parity Parity generates a set of redundancy data from two or more parent data sets. The redundancy data can be used to reconstruct one of the parent data sets in the event of a drive failure. Parity data does not fully duplicate the parent data sets, but parity generation can slow the write process.
Page 42: 2.4.12 Disk Spanning
2.4.12 Disk Spanning Disk spanning allows multiple drives to function like one big drive. 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 43: 2.4.13 Hot Spares
Table 2.2 Spanning for RAID 10, RAID 50, and RAID 60 Level Description Configure RAID 00 by spanning two contiguous RAID 0 virtual drives, up to the maximum number of supported devices for the controller. Configure RAID 10 by spanning two contiguous RAID 1 virtual drives, up to the maximum number of supported devices for the controller.
Page 44 If the hot spare is designated as having enclosure affinity, it will attempt to rebuild any failed drives on the backplane that it resides in before rebuilding any other drives on other backplanes. Note: If a rebuild to a hot spare fails for any reason, the hot spare drive will be marked as "failed".
Page 45: 2.4.14 Disk Rebuilds
• You must assign the hot spare to one or more drives through the controller 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.
Page 46: 2.4.15 Rebuild Rate
An automatic drive rebuild 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.
Page 47: 2.4.18 Virtual Drive States
Table 2.3 Drive States (Cont.) State Description Hot Spare A drive that is powered up and ready for use as a spare in case an online drive fails. Failed A drive that was originally configured as Online or Hot Spare, but on which the firmware detects an unrecoverable error.
Page 48: 2.4.19 Enclosure Management
2.4.19 Enclosure Management Enclosure management is the intelligent monitoring of the disk subsystem by software and/or hardware. The disk subsystem can be part of the host computer or can reside in an external disk enclosure. Enclosure management helps you stay informed of events in the disk subsystem, such as a drive or power supply failure.
Page 49: Selecting A Raid Level
RAID 10, a combination of RAID 0 and RAID 1, consists of striped data across mirrored spans. A RAID 10 drive group is a spanned drive group that creates a striped set from a series of mirrored drives. RAID 10 allows a maximum of eight spans.
Page 50: Raid 0
2.5.3 RAID 0 RAID 0 provides disk striping across all drives in the RAID drive group. RAID 0 does not provide any data redundancy, but, along with RAID 0, does offer the best performance of any RAID level. RAID 0 breaks up data into smaller segments, and then stripes the data segments across each drive in the drive group.
Page 51: Raid 5
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.
Page 52: Raid 5 Drive Group With Six Drives
RAID 5 addresses the bottleneck issue for random I/O operations. Because each drive contains both data and parity, numerous writes can take place concurrently. Table 2.7 provides an overview of RAID 5. Figure 2.7 provides a graphic example of a RAID 5 drive group. Table 2.7 RAID 5 Overview Provides high data throughput, especially for large files.
Page 53: Raid 6
2.5.6 RAID 6 RAID 6 is similar to RAID 5 (disk striping and parity), except that instead of one parity block per stripe, there are two. With two independent parity blocks, RAID 6 can survive the loss of two drives in a virtual drive without losing data.

span. You must use an even number of drives in each RAID 10 virtual drive in the span. Note: Other factors, 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.
Page 57: Raid 50 Overview
50 is best implemented on two RAID 5 drive groups with data striped across both drive groups. RAID 50 breaks up data into smaller blocks and then stripes the blocks of data to each RAID 5 disk set. RAID 5 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks and then writes the blocks of data and parity to each drive in the drive group.
Page 58 2.5.10 RAID 60 RAID 60 provides the features of both RAID 0 and RAID 6, and includes both parity and disk striping across 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.
Page 59: Raid Configuration Strategies
Table 2.12 RAID 60 Overview Weak Points Not well suited to tasks requiring lot of writes. A RAID 60 virtual drive has to generate two sets of parity data for each write operation, which results in a significant decrease in performance during writes. Drive performance is reduced during a drive rebuild.
Page 60: Maximizing Fault Tolerance
maximize virtual drive availability (fault tolerance), virtual drive performance, and virtual drive capacity. 2.6.1 Maximizing Fault Tolerance Fault tolerance is achieved through the ability to perform automatic and transparent rebuilds using hot spare drives and hot swaps. A hot spare drive is an unused online available drive that the RAID controller instantly plugs into the system when an active drive fails.
Page 61: Maximizing Performance
RAID Level Fault Tolerance Combines distributed parity with disk striping. RAID 6 can sustain two drive failures and still maintain data integrity. Parity provides redundancy for two drive failures without duplicating the contents of entire drives. If a drive fails, the RAID controller uses the parity data to reconstruct all missing information.
Page 62: Raid Levels And Performance
Table 2.14 RAID Levels and Performance RAID Level Performance RAID 0 (striping) offers excellent performance. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the drive group. Disk striping writes data across multiple drives instead of just one drive. It involves partitioning each drive storage space into stripes that can vary in size from 8 KB to 1024 KB.
Page 63: Maximizing Storage Capacity
RAID Level Performance RAID 50 works best when used with data that requires high reliability, high request rates, and high data transfer. It provides high data throughput, data redundancy, and very good performance. Spanning increases the capacity of the virtual drive and improves performance by doubling the number of spindles.
Page 64: Raid Availability
RAID Level Capacity RAID 5 provides redundancy for one drive failure without duplicating the contents of entire drives. RAID 5 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, then writes the blocks of data and parity to each drive in the drive group.
Page 65: Configuration Planning
2.7.1.1 Spare Drives You can use spare drives to replace failed or defective drives in a drive group. A replacement drive must be at least as large as the drive it replaces. Spare drives include hot swaps, hot spares, and cold swaps. A hot swap is the manual substitution of a replacement unit in a disk subsystem for a defective one, where the substitution can be performed while the subsystem is running (performing its normal functions).
Page 66: Number Of Drives
Each type of data stored in the disk subsystem has a different frequency of read and write activity. If you know the data access requirements, you can more successfully determine a strategy for optimizing the disk subsystem capacity, availability, and performance. Servers that support video on demand typically read the data often, but write data infrequently.

Page 71: Workflow
Option Description Security Key A key based on a user-provided string. The controller uses the security key to lock and unlock access to the secure user data. This key is encrypted into the security key blob and stored on the controller. If the security key is unavailable, user data is irretrievably lost.
Page 72: Change Security
3.4.1.2 Create the Security Key You need to enter the security key to perform certain operations. You can choose a strong security key that the controller suggests. Caution: If you forget the security key, you will lose access to your data. 3.4.1.3 Create a Passphrase (Optional) The pass phrase provides additional security.
Page 73: Create Secure Virtual Drives
3.4.2.1 Change the Security Key Identifier You have the option to edit the security key identifier. If you plan to change the security key, it is highly recommended that you change the security key identifier. Otherwise, you will not be able to differentiate between the security keys.
Page 74: Import A Foreign Configuration
3.4.3.2 Advanced Configuration If you select advanced configuration, select the drive security method, and add the drives to the drive group. Section 8.1.3, “Creating a Virtual Drive Using Advanced Configuration” for the procedures used to import a foreign configuration. After the drive group is secured, you cannot remove the security without deleting the virtual drives.
Page 75: Instant Secure Erase
Instant Secure Erase Instant Secure Erase is a method of data erasure that you can use with FDE drives. After the initial investment into a FDE disk, there is no additional cost in dollars or time to erase data using the Instant Secure Erase feature.
Page 76 If there is a need to replace drives – If the amount of data has outgrown the storage system, and there is no room to expand capacity by adding drives, you might choose to purchase upgrade drives. If the older drives support FDE, you can erase the data instantly so the new drives can be used.

Page 101 RAID 6 is best suited for networks that perform a lot of small input/output (I/O) transactions simultaneously. It provides data redundancy, high read rates, and good performance in most environments. In the case of a failure of one drive or two drives in a virtual drive, the RAID controller uses the parity blocks to recreate all of the missing information.

Page 350 cache flush A controller property that indicates how often the data cache is flushed. interval caching The process of using a high speed memory buffer to speed up a computer system’s overall read/write performance. The cache can be accessed at a higher speed than a drive subsystem. To improve read performance, the cache usually contains the most recently accessed data, as well as data from adjacent drive sectors.
Page 351 configuration for a drive group (for example, a specific arrangement of drive group members on the device I/O buses). The copyback operation can be run automatically or manually. Typically, a drive fails or is expected to fail, and the data is rebuilt on a hot spare.
Page 352 • Unconfigured Good: A drive accessible to the RAID controller but not configured as a part of a virtual drive or as a hot spare. • Hot Spare: A drive that is configured as a hot spare. • Online: A drive that can be accessed by the RAID controller and will be part of the virtual drive.

MegaRAID Storage Manager software allows you to import the existing configuration to the RAID controller, or you can clear the configuration so you can create a new one.
Page 354 IO policy A virtual drive property indicating whether Cached I/O or Direct I/O is being used. In Cached I/O mode, all reads are buffered in cache memory. In Direct I/O mode, reads are not buffered in cache memory. Data is transferred to cache and the host concurrently. If the same data block is read again, it comes from cache memory.
Page 355 NVRAM Acronym for non-volatile random access memory. A storage system that does not lose the data stored on it when power is removed. NVRAM is used to store firmware and configuration data on the RAID controller. NVRAM present A controller property indicating whether an NVRAM is present on the controller.
Page 356 RAID 1 Uses data mirroring on pairs of drives so that data written to one drive is simultaneously written to the other drive. RAID 1 works well for small databases or other small applications that require complete data redundancy. RAID 5 Uses data striping and parity data across three or more drives (distributed parity) to provide high data throughput and data redundancy, especially for applications that require random access.
Page 357 rebuild The regeneration of all data to a replacement drive in a redundant virtual drive after a drive failure. A drive rebuild normally occurs without interrupting normal operations on the affected virtual drive, though some degradation of performance of the drive subsystem can occur. rebuild rate The percentage of central processing unit (CPU) resources devoted to rebuilding data onto a new drive after a drive in a storage configuration...

Page 359 write-back In Write-Back Caching mode, the controller sends a data transfer completion signal to the host when the controller cache has received all of the data in a drive write transaction. Data is written to the drive subsystem in accordance with policies set up by the controller. These policies include the amount of dirty/clean cache lines, the number of cache lines available, and elapsed time from the last cache flush.
