About RAID

A RAID disk array is a group of independent physical disks that provides high performance by increasing the number of drives used for saving and accessing data. A RAID disk subsystem improves I/O performance and data availability. The physical disks appear to the host system either as a single storage unit or multiple logical units. Data throughput improves because several disks are accessed simultaneously. RAID systems also improve data storage availability and fault tolerance. Data loss caused by a physical disk failure can be recovered by rebuilding missing data from the remaining physical disks containing data or parity.

NOTE:

is no redundancy for this RAID level. However, when a physical disk in a RAID 1, RAID 5, or RAID 10 fails, data is preserved because there is redundancy with these RAID levels.

Summary of RAID Levels

When a physical disk in a RAID 0 virtual disk fails, data is lost because there

•Volume logical volume on which data is stored.

• RAID 0 uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy.

• RAID 1 uses disk mirroring so that data written to one physical disk is simultaneously written to another physical disk. RAID 1 is good for small databases or other applications that require small capacity but also complete data redundancy.

• RAID 5 uses disk striping and parity data across all physical disks (distributed parity) to provide high data throughput and data redundancy.

• RAID 10 uses disk striping across two mirrored sets. It provides high data throughput and complete data redundancy.

Disk Striping

Disk striping allows you to write data across multiple physical disks instead of just one physical disk. Disk striping involves partitioning each physical disk storage space into stripes of the various sizes. These stripes are interleaved in a repeated sequential manner. The part of the stripe on a single physical disk is called a stripe element.

For example, in a four-disk system using only disk striping (used in RAID level 0), segment 1 is written to disk 1, segment 2 is written to disk 2, and so on. Disk striping enhances performance because multiple physical disks are accessed simultaneously, but disk striping does not provide data redundancy.

Figure 2-1 shows an example of disk striping.

Figure 2-1. Example of Disk Striping (RAID 0)

Disk Mirroring

With mirroring (used in RAID 1), data written to one disk is simultaneously written to another disk. If one disk fails, the contents of the other disk can be used to run the system and rebuild the failed physical disk. The primary advantage of disk mirroring is that it provides 100 percent data redundancy. Because the contents of the disk are completely written to a second disk, it does not matter if one of the disks fails. Both disks contain a copy of the same data at all times. Either of the physical disks can act as the operational physical disk. Disk mirroring provides 100 percent redundancy, but is expensive because each physical disk in the system must be duplicated.

Figure 2-2 shows an example of disk mirroring.

Figure 2-2. Example of Disk Mirroring (RAID 1)

Mirrored physical disks improve read performance by read load balancing.

The PERC S300 controller only supports physical disks (SAS and SATA). SSD

Spanned RAID Levels

Spanning is a term used to describe the way in which RAID level 10 is constructed from multiple sets of simpler RAID levels. For example, a RAID 10 has multiple sets of RAID 1 disk arrays in which each RAID 1 set is considered a span. Data is then striped (as it is in RAID 0) across the RAID 1 spans to create a RAID 10 virtual disk.

Parity Data

Parity data is redundant data that has been generated to provide fault tolerance within certain RAID levels. In the event of a drive failure, the parity data can be used by the controller to regenerate user data. Parity data is present only for RAID 5 disk arrays.

The parity data is distributed across all the physical disks in the system. If a single physical disk fails, it can be rebuilt from the parity and the data on the remaining physical disks. RAID 5 combines distributed parity with disk striping, as shown in Figure 2-3. Parity provides redundancy for one physical disk failure without duplicating the contents of entire physical disks.

General Features

The features of the Dell PowerEdge RAID Controller (PERC) S100 and PERC S300 adapter are described in Table 3-1.

Automatic virtual disk rebuild

Background Array Scan (BAS)

Background virtual disk initialization (BGI)

Rebuilds a redundant virtual disk automatically when a failure is detected, if a hot spare is assigned for this capability.

Verifies and corrects correctable media errors on mirror, volume, or parity data for virtual disks. BAS starts automatically after a Virtual Disk is created while in the OS.

The background initialization of a redundant virtual disk creates the parity data that allows the virtual disk to maintain its redundant data and survive a physical disk failure.

Because background initialization helps the controller to identify and correct problems that might occur with the redundant data at a later time, background initialization is similar to a consistency check.

Background initialization allows a redundant virtual disk to be used immediately. Data is lost if a physical disk fails before the completion of a BGI.

NOTE:

Command queuing allows the host to issue multiple input/output requests to a disk simultaneously. The disk can then decide in which order to process the commands to achieve maximum performance.

The SATA and SAS versions of command queuing have slightly different protocols and means of handling multiple traffic requests at the same time, but the end-purposes are comparable.

A consistency check is a background operation that verifies and corrects the mirror or parity data for fault-tolerant physical disks. It is recommended that you periodically run a consistency check on the physical disks.

By default, a consistency check corrects mirror or parity inconsistencies. After the data is corrected, the data on the primary physical disk in a mirror set is assumed to be the correct data and is written to the secondary physical disk in the mirror set.

A consistency check cannot be user-initiated in the PERC Virtual Disk Management utility. However, a consistency check can user-initiated when using Dell OpenManage Server Administrator Storage Management.

physical disk, so that the controller can use the physical disk.

PERC S100 adapter and PERC S300 adapter, in order to prevent data loss in case of a failed physical disk:

• Physical disk failure detection (automatic).

• Virtual disk rebuild using hot spares (automatic, if the hot spare is configured for this functionality).

• Parity generation and checking (RAID 5 only).

• Hot-swap manual replacement of a physical disk without rebooting the system (only for systems with a backplane that allows hot-swapping).

If one side of a RAID 1 (mirror) fails, data can be rebuilt by using the physical disk on the other side of the mirror.

If a physical disk in RAID 5 fails, parity data exists on the remaining physical disks, which can be used to restore the data to a new, replacement physical disk configured as a hot spare.

If a physical disk fails in RAID 10, the virtual disk remains functional and data is read from the surviving mirrored physical disk(s). A single disk failure in each mirrored set can be sustained, depending on how the mirrored set fails.

Online Capacity Expansion (OCE)

Physical disks (general)

OCE is a process that allows you to add storage capacity to an existing virtual disk. In most cases additional storage capacity can be added without taking the system offline. However, if an additional physical disk needs to be added and the system does not support hot-swapping, the system must be turned off.

OCE enables you to increase the total storage capacity of a virtual disk by integrating unused storage with the virtual disk.

Data can be accessed while the physical disks are added (if a system has hot-swap capability) and while data on the virtual disk is being redistributed.

For Volume and RAID 1, OCE expands the virtual disk by using the available space of the physical disks that are already members of the virtual disk. For RAID 0, RAID 5 and RAID 10, additional capacity can be attained by adding physical disks to the virtual disk.

The PERC S100 adapter supports up to four SATA HDD or SSD physical disks. The PERC S300 adapter supports up to eight SAS or SATA HDD physical disks.

A maximum of eight physical disks can be used for RAID 0 and RAID 5. A maximum of two physical disks can be used for RAID 1. A maximum of four physical disks can be used for RAID 10.

If a physical disk fails during system startup, the controller identifies the failed physical disk as follows:

RAID Controller Feature Description

Virtual disks (general) Up to eight virtual disks are supported.

The PERC S100 adapter and PERC S300 adapter allows:

• Creating virtual disks of different RAID levels on a single controller.

• Creating different RAID level virtual disks on the same physical disk, to adapt each virtual disk to the I/O that it processes.

• Building different virtual disks with different characteristics for different applications.

The PERC S100 adapter and PERC S300 adapter does not allow:

• Creating a virtual disk from a mix of different type physical disks. For example, a RAID 10 virtual disk cannot be created from two SATA-II HDD physical disks, a SAS HDD physical disk, and a SSD physical disk. All of the physical disks must be the same interface (SAS or SATA) and drive type (HDD or SSD).

(continued)

• Selecting a physical disk as a dedicated hot spare if the physical disk is a different type from the physical disk or disks.

A virtual disk refers to data storage created by the controller from one or more physical disks. Although a virtual disk can be created from several physical disks, it is seen by the operating system as a single disk.

The capacity of a virtual disk can be expanded online for any RAID level, without the operating system being rebooted.

Table 7-11. Cannot Assign a Dedicated Hot Spare to a Virtual Disk

Likely Causes to Check Corrective Actions

The RAID level does not allow a dedicated hot spare to be created

The designated physical disk does not have sufficient capacity to be a dedicated hot spare

The physical disk is already part of a virtual disk

The physical disks are of different types

Hot spares cannot be created for Volume or RAID 0 virtual disks.

The capacity of the physical disk selected to be a dedicated hot spare must be equal to or larger than the capacity of the smallest physical disk in the virtual disk. For example, if the physical disk selected for a dedicated hot spare is 160 GB, and the physical disks in the virtual disk are 80 GB, 160 GB, and 500 GB, a dedicated hot spare can be assigned. That is because the physical disk selected for the dedicated hot spare is larger than the smallest (80 GB) physical disk in the virtual disk.

A dedicated hot spare cannot be assigned to another virtual disk.

The physical disk used as a dedicated spare must be the same type as the physical disks that are already part of the virtual disk. For example, if a virtual disk consists of SATA-II physical disks, the dedicated hot spare must be a SATA-II physical disk.

RAID Technology - Understanding Disk Arrays and Virtual Disks

A disk array consists of the physical disks that are connected to a controller. A virtual disk is data storage created by a controller from one or more physical

disks. The virtual disk is viewed by the operating system as a single disk. The Dell PowerEdge RAID Controller (PERC) S100 controller and PERC

S300 controller allows:

• SAS HDD (PERC S300 controller only), SATA HDD, and/or SATA SSD (PERC S100 controller only) physical disks to co-exist on a single controller.

• Physical disks of the same type (SAS HDD, SATA HDD, SATA SSD) but of different capacities.

• Virtual disks to be at different RAID levels on the same controller, but not supported on the same group of physical disks.

Because some RAID levels enhance performance while others improve reliability, it is important to consider your needs when planning a virtual disk configuration.

The ability of the controller to provide online expansion to virtual disks across multiple physical disks and controllers becomes extremely valuable when storage expansion is a requirement.

Appendix B

Understanding RAID Levels

A PERC S100 controller or PERC S300 controller supports the following RAID levels:

Table B-1. RAID Levels and Characteristics

RAID Level Main Characteristics Advantages

Volume (can be created only using the PERC S100 Virtual Disk Management utility or PERC S300 Virtual Disk Management utility. Dell OpenManage Server Administrator Storage Management can manage a Volume but cannot create it.)

NOTE:

mentioned otherwise, the term PERC Virtual Disk Management utility refers to both the PERC S100 Virtual Disk Management utility and the PERC S300 Virtual Disk Management utility

Unless

A virtual disk type that links available space on a single physical disk and forms a single logical volume on which data is stored.

• Concatenation allows access to a single physical disk.

• Concatenation does not provide performance benefits or data redundancy.

• When a physical disk in a concatenated virtual disk fails, data is lost from that virtual disk. Because there is no redundancy, data can be restored only from a backup.

RAID 0 (striping) Provides the highest

performance, but no data redundancy. Data in the virtual disk is striped (distributed) across two or more physical disks.

Appendix B

RAID 0 virtual disks are useful for holding information, such as the operating system paging file, where performance is extremely important but redundancy is not.

Page 83

Table B-1. RAID Levels and Characteristics

RAID Level Main Characteristics Advantages

(continued)

RAID 1 (mirroring) Mirrors data on one physical

disk to another, to provide basic redundancy.

In the event of a single physical disk failure a second copy of the data exists, which can be used to restore the data to a new, replacement physical disk.

RAID 10 (striped mirror sets)

Combines mirrored and striped sets; data are striped across mirrored sets of physical disks.

RAID 10 allows multiple physical disk failures, up to one failed physical disk in each mirror that has been striped.

In the event of a single physical disk failure (per mirror set) a second copy of the data exists, which can be used to restore the data to a new, replacement physical disk.

Useful when only two physical disks are available, and when data integrity is more important than storage capacity.

• Offers better performance than a simple mirror because of the additional physical disks.

• Requires twice the disk space of RAID 0 to offer redundancy.

• When a physical disk in a RAID 10 virtual disk fails, the virtual disk is still functional. Data is read from the surviving mirrored disk.

Appendix B

Page 84

Table B-1. RAID Levels and Characteristics

RAID Level Main Characteristics Advantages

(continued)

RAID 5 (striping with parity)

Stripes data, as well as parity, across all physical disks in the virtual disk. Parity information is interspersed across the virtual disk.

In the event of a single physical disk failure, parity data exists on the remaining physical disks, which can be used to restore the data to a new, replacement physical disk.

• Offers exceptional read performance, as well as redundancy.

• Requires only one extra physical disk to offer redundancy.

• For most systems with three or more physical disks this is the best choice as a RAID level.

Disk States - Virtual and Physical Disks

The following tables indicate the statuses that can appear at the PERC Virtual Disk Management utility.

Table B-2. Physical Disk States

State Definition

ATAPI Indicates a peripheral device (CD-ROM, DVD, or tape drive) instead

of a physical disk. An ATAPI device cannot be initialized or added to a virtual disk.

Non-Raid A physical disk has been moved from another, non-PERC S100

controller or non-PERC S300 controller.

Online The physical disk has been initialized and is part of a virtual disk. Ready The physical disk has been initialized but is not currently used in a

virtual disk.

Failed A failed physical disk appears as Failed only when (a) View Virtual

Disk Details is selected, and (b) the virtual disk to which the physical

disk belongs is selected. The Failed status is reported only when the physical disk is part of a virtual disk.

Spare A physical disk that is assigned as a dedicated or global hot spare.

Appendix B

Page 85

Table B-3. Virtual Disk States

State Definition

Degraded A physical disk in a redundant virtual disk has failed. Additional failures

might result in lost data.

Failed One or more physical disks have failed. The virtual disk has gone offline.

The virtual disk cannot restore the data.

Non-Raid A Non-Raid physical disk is automatically linked to a Non-Raid virtual

disk for use with a PERC S100 controller or PERC S300 controller.

Normal A virtual disk has been created and its preparation process has been

completed.

Ready A redundant virtual disk has been created, and is ready for additional

preparation.

Failure States

Whether a virtual disk is marked as Failed or Degraded depends upon what RAID level virtual disk it is, and how many physical disks of the virtual disk have failed. In Table B-4 note the changes in state.

If a rescan of all channels is performed after disconnecting a physical disk, the state of every virtual disk using the disconnected physical disk changes from the Ready state to either the Failed or Degraded state, depending on the virtual disk’s RAID level.

For additional information about rescanning to update storage configuration changes, see the OpenManage documentation available on the Dell Support website at support.dell.com/manuals.

Table B-4. Failure Status by Virtual Disk RAID Level

Virtual Disk RAID Level Failure Status Description

RAID 1, RAID 5 Degraded A single physical disk fails. RAID 10 Degraded A single physical disk fails in one or

more of the mirrored sets. Volume, RAID 0 Failed A single physical disk fails. RAID 1 or RAID 5 Failed Two or more physical disks fail. RAID 10 Failed Two physical disks in a mirrored set

fail.

Creating Virtual Disks: Future Expansion

When creating virtual disks, consider whether or not the virtual disk capacity needs to be expanded in the future.

For a

Microsoft Windows operating system, format the virtual disks with New Technology File System (NTFS). Microsoft Corporation provides a utility (diskpart.exe) that can dynamically extend an NTFS file system onto any unused adjacent space.

Note also that using a single partition per virtual disk makes expansion much easier.

NOTE:

operating system is running.

NOTE:

Windows operating systems, or on the Microsoft Corporation website (microsoft.com) for other versions. Use the correct version for your operating system.

The diskpart.exe utility version depends on which version of the Windows

Understanding Physical Disks

Physical Disk States

Within the management applications, physical disks can be part of one or more virtual disks and can exist in the states indicated:

Table B-5. Minimum and Maximum Physical Disk Configurations

RAID Level Minimum Number of Physical Disks Maximum Number of Physical Disks

RAID 0 2 8 RAID 1 2 2 RAID 10 8 8 RAID 5 3 8

Appendix B

Page 87

Rescanning Physical Disks for Changes in State

The physical disk information displayed at the PERC Virtual Disk Management utility is the state of the physical disks when they were last scanned. If a rescan has not been performed, the information displayed is the state of the physical disks at boot time.

Every time a physical disk is connected or disconnected while online, a rescan is performed. A rescan is automatically performed when Dell OpenManage Server Administrator Storage Management detects that a physical disk has been added or removed.

Dedicated Hot Spares

A dedicated hot spare is a backup physical disk for the redundant virtual disk to which it is assigned. The physical disk that is used as a dedicated hot spare cannot be a member of an existing virtual disk. When the hot spare is activated, it becomes the receptacle for the data from the failed physical disk member of the volume, without interrupting the system or requiring your intervention.

A dedicated hot spare can be assigned to any redundant virtual disk, and up to four hot spares can be assigned to a virtual disk. However, a dedicated hot spare cannot be assigned while a task is running on the virtual disk.

A global hot spare can be assigned when a virtual disk is created in the PERC Virtual Disk Management utility. A global hot spare can be added at any time when Storage Management is used.

If there is enough space available on the dedicated hot spare, and a disk failure occurs, the rebuild process for the virtual disk starts automatically.

Dedicated hot spare assignments do not apply to a non-redundant virtual disk.

NOTE:

state, or if the SAS/SATA cable to the physical disk or power cable is disconnected.

A virtual disk is marked Failed or Degraded if a physical disk reports a Failed

A dedicated hot spare is often preferred to a global hot spare, especially for critical data. This is because a dedicated hot spare guarantees that the virtual disk has a backup physical disk assigned exclusively to it in case of a failure.

For additional information, see "Managing Global Hot Spares" on page 56.

Appendix B

Page 88

Global Hot Spares

A global hot spare is a backup physical disk that can be used by any redundant virtual disk. It is not assigned (dedicated) to any specific virtual disk.

Virtual disks can typically be rebuilt by using a global spare disk, as long as the global hot spare is not already part of the virtual disk and has enough available capacity. Unlike a dedicated hot spare, a global hot spare can be assigned at anytime, even while tasks are running on virtual disks.

If there is enough space available on the global hot spare, and a disk failure occurs, the rebuild process for the virtual disk starts automatically.

Regulatory Notices

Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or conducted along power or signal leads, that endangers the functioning of a radio navigation or other safety service or seriously degrades, obstructs, or repeatedly interrupts a licensed radio communications service. Radio communications services include, but are not limited to, AM/FM commercial broadcast, television, cellular services, radar, air-traffic control, pager, and Personal Communication Services (PCS). These licensed services, along with unintentional radiators such as digital devices, including computers, contribute to the electromagnetic environment.

Electromagnetic Compatibility is the ability of items of electronic equipment to function properly together in the electronic environment. While this system has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference may not occur in a particular installation. If this equipment does cause interference with radio communications services, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:

• Reorient the receiving antenna.
