Initial conﬁguration methods

The SMU provides two methods to initially conﬁgure your system:

• The Wizard tab—includes the Initial System Conﬁguration Wizard, which is the easiest and

simplest method for initially conﬁguring the storage system. You are prompted in a logical sequence for storage, iSCSI, logon, and management settings. The wizard then uses those settings to conﬁgure the storage and make it available to the initiator. This conﬁguration method is best for single-server environments needing bulk storage, because one target is created, and is assigned to one initiator. For information about using the wizard, see “Wizards”onpage69.

• The Conﬁgure tab—offers more ﬂexibility than the wizard when conﬁguring the storage.

This conﬁguration method is best for multi-server environments that need to customize the creation of storage LUNs and targets. For information about using the Conﬁgure tab, see “Conﬁgure”onpage25.

Changing the management port IP address through the MSA1510i controller display panel

When the MSA1510i is initially installed and powered on, an IP address is automatically assigned to the primary management port (usually MA0). Depending on your network conﬁguration,thisdefaultIP address may not be accessible by the network servers.

To change the IP address of the MSA1510i management port to be in the same LAN segment as the network servers, do the following:

1. Access the controller LCD panel management menu. Press the right (>) navigation button on the

front of the active controller (usually the front-right controller.) Network Settings should be displayed and blinking.

LCD panel navigation buttons work as follows:

Navigation button In the menu Within a menu option

Right (>) Select a blinking menu option.

When changing IP address settings, move to the next digit.

Up/Down (^/v)

Left (<)

Change/Toggle a setting. Accept the displayed setting and

return to the initial management menu display.

Page 17

2. Disable DHCP.

a. With Network Settings displayed and blinking, press > to select it. b. Press ^ or v until DHCP Enabled is displayed and blinking, and then press > to select it. c. Press ^ or v to change the setting to No. d. Press < to accept the new setting and return to the initial management menu display.

3. Change the IP address.

a. With Network Settings displayed and blinking, press > to select it. b. Press ^ or v until IP Address is displayed and blinking, and then press > to select it. c. Press ^ or v to scroll through and select the value for each digit of the IP address. d. After entering all digits of the new IP address, press < to accept the new setting and return to the

initial management menu display.

4. Verify and, if necessary, change the Subnet Mask, Default Gateway, Primary DNS, Secondary DNS,

and VLAN ID using procedures similar to those outlined in step 3, but pressing ^ or v to navigate to the desired menu option.

5. After all changes are entered, exit the management menu.

Press v until Exit is displayed and blinking, and then press >. The LCD panel returns to the display mode.

6. Verify that the IP address was entered correctly by pressing ^ or v until the Port #MA0 IP message

is displayed.

7. Verify that the server can locate the MSA1510i by opening a command prompt window and using

the ping command.

• Create fault-tolerant logical storage units—Create LUNs using fault-tolerant RAID levels and striping methods.

• When assigning system names and aliases, use only the following characters:

• Uppercase alpha characters (A-Z)

• Lowercase alpha characters (a-z)

•Numericcharacters(0-9)

• Special characters (! # = ( ) ‘ ; , . and space)

• When accessing the SMU, expand the browser to full screen or a minimum size of 1024 x 768

pixels. Other settings may distort the display or cause items to not display.

• When planning and conﬁguring logical drives:

• Optimize performance and redundancy by striping the drives in the array across separate

storage enclosures on different SCSI buses, especially in mirrored environments using RAID 1+0.

• Set the drive rebuild priority to high to minimize exposure during a drive failure.

• Customize the RAID level and striping method to the type of data that will be stored on the

logical drive.

NOTE:

Depending on the number of physical hard drives included in a storage unit, the SMU may suggest RAID 6 (ADG) as the default RAID level, which offers a high level of fault tolerance and usable disk capacity, but at a signiﬁcant cost to I/O performance. For comparable fault tolerance but higher performance, consider using RAID 1+0 when fault tolerance is desired and performance is more important than usable capacity. Reserve RAID 6 (ADG) for situations when fault tolerance is desired, but usable capacity is more important than performance.

• After conﬁguring the storage, remember to:

• Verify that each initiator has been granted access to the target.

• Control access to the storage through the use of VLANs, CHAP authentication, and ACLs.

• Draw physical and logical diagrams of your network:

• Hardware/device diagram—Physical layout of the entire network, including device names

and cabling.

• Storage diagram—Hard drive and storage system conﬁguration, including RAID levels.

• Path/Accessibility diagram—Access information, including which devices are allowed to

w system includes the following tasks, performed in the following sequence:

age targets

Conﬁguring management and data ports

As described in the installation documents, the array connects to the network switch from its Ethernet iSCSI module.

IMPORTANT:

In dual-controller conﬁgurations, an additional Ethernet iSCSI module is installed in the chassis, providing the redundant path to a separate iSCSI network switch. Ports on both modules must be conﬁgured.

When conﬁguring management and data ports, consider the following:

• Isolate management trafﬁcfromstoragetrafﬁc, by assigning IP addresses in different LAN

segments.

• Assign one (or more) IP addresses to each port, and then assign one (or more) TCP portals

to each IP address.

• Enable/disable the following management services as needed for your environment:

• TELNET (default: disabled)

•SSH(default:enabled)

• HTTP (default: enabled)

•HTTPS(default:enabled)

• SNMP (default: enabled)

• Assign IP addresses and TCP portals to the data ports as outlined on your Path/Accessibility

Diagram. (When conﬁguring the storage targets, each target is assigned to a speciﬁcgroupofIP portals, controlling access to the storage and the ﬂow of storage trafﬁc.)

NOTE:

The maximum supported number of IP addresses and portals may differ, depending on the storage system and the model of its supported array controller. See your system user documents for more information.

Conﬁguring the management port

IMPORTANT:

Dual-controller conﬁgurations should conﬁgure the management port associated with each controller.

• The default management port for controller A is MA0.

• The default management port for controller B is MB0.

1. To clarify the display, expand the View as drop-down box and select the iSCSI view.

2. Expand (+) the component list for an installed MSA1510i controller.

(default) to use the SMU. If the management port state was disabled,youmustusetheCommandLineInterface(CLI)tore-enableit.(Formore information, see the Command Line Interface user guide.)

•AssignaHost Name to the storage system (default: chassis serial number). HP recommends changing this to a more helpful user-deﬁned value.

• Port Name MA0 is the default management port. Although other ports can be conﬁgured as the primary management port, HP recommends conﬁguring and using the default.

• To control the path of management trafﬁc to and from the array controller and to add one level of system security, HP recommends assigning a static IP address to the management port that is in a different LAN segment than the data ports. To assign a static IP address, expand the DHCP Setting drop-down box and change the setting to Disabled. The page expands (shown), showing the currently assigned IP address. Change this to the address you want to use for management trafﬁc. After changing the IP address, you may need to re-connect to the SMU using the newly assigned IP address.

•Bydefault,VLAN ID is 0, meaning that trafﬁc ﬂowing from the port to the switch will be untagged. ToassignaVLANforthisporttouse,enteritsvalue.VLANsaresetupon theswitch,andareusedasonemethodofcontrollingaccesstothestoragesystem.

IMPORTANT:

For dual-controller conﬁgurations, repeat these steps to conﬁgure the management port on the other controller.

• The default management port for controller A is MA0.

• The default management port for controller B is MB0.

Conﬁguring data ports

Conﬁguring each data port includes two steps:

• Assigning one or more IP addresses to the port (Step 1).

• Assigning one or more TCP portals to each IP address (Step 4).

IMPORTANT:

Conﬁgure all data ports you plan to use, including ports on the Ethernet iSCSI module associated with the controller in slot 2, if installed.

1. Select Data Port > Add IP Address.

2. Enter settings for the data port.

NOTE:

• To control the path of storage trafﬁc to and from the array controller and to add one level of system security, HP recommends assigning an IP Address to the data port that is in a different LAN segment than the management port. This IP address can not be changed

. To change an IP address assigned to a port, you must add a new IP address and then delete the unneeded entry. When deleting an IP address, all corresponding portals and portal group assignments are also deleted.

3. Select the hard drives to include in the array.

NOTE:

• The SMU does not allow hard drives from SATA and SCSI storage enclosures to be included in the same array.

• Harddrivesincludedinanarrayshouldbethesamesizeandspeed.Whendrivesizes and speeds are mixed within an array, the usable capacity and the processing ability of the array is reduced to that of the smallest and slowest hard drive.

• For optimum performance of an array, include hard drives from different storage enclosures and connected to different SCSI buses on the array controller.

• Consider reserving some hard drives for use as on-line spares.

• For more information about conﬁguring storage arrays, see “Storage overview”onpage85.

4. When the display refreshes, verify that the newly conﬁgured array is shown in the component list.

5. Repeat Step 2 through Step 4 to conﬁgure additional arrays from any remaining unused hard drives.

Assigning spare drives to an array

HP recommends reserving some hard drives in your enclosures to be used as spare drives. Spares are drives that are assigned to one or more arrays, but are not active members of those arrays. If a spare is present and a physical drive in the array fails, the spare automatically replaces the failed drive as a member of the array unit, and the process of rebuilding the information onto the spare automatically begins. The system uses mirrored or parity information from the other member drives to reconstruct information onto the spare drive. After the failed drive is replaced, data on the spare is automatically copied to the replacement drive, and the spare is again available for use as a spare.

1. Select Array > Spare Management.

2. Select the hard drive(s) to assign as a spare.

NOTE:

• Asparemustbethesametype(SATAorSCSI)asotherdrivesinthearray.

2. As needed, expand the drop-down boxes in the task area to change the settings from the suggested

defaults.

NOTE:

• The SMU suggests defaults for the logical drive, creating one large logical drive from all unused space on the array, with the highest fault tolerance and performance possible for the hard drives included in that array.

•OnlyFault Tolerance levels possible for the array are displayed. For example, RAID 5 is not listed if the array has only two physical hard drives.

•ThedefaultStripe Size gives optimum performance in a mixed read/write environment.

• For read-prominent environments, use a larger stripe size.

• For write-prominent environments, use a smaller stripe size for RAID 5 or

RAID_ADG,andalargerstripesizeforRAID0orRAID1+0.

• To build multiple logical drives on the same array, reduce the Size setting from the default to a smaller amount. Additional logical drives can then be built from the remaining unused space.

•DisablingtheArray Accelerator for a logical drive reserves use of the accelerator cacheforotherlogicaldrivesinthearray. Thisfeatureisusefulifyouwanttheother logicaldrivestohavethemaximumpossibleperformance.

3. When the display refreshes, verify that the conﬁgured logical drives are shown in the component list.

4. To map additional logical drives to this same target, repeat Step 1 through Step 3 in this section.

Conﬁguring the redundant controller for a target (dual-controller conﬁgurations only)

IMPORTANT:

Dual-controller conﬁgurations must create an additional portal group for each target, using portals on the redundant Ethernet iSCSI module to establish a redundant path. Redundant data ports include SB0, and SB1. For targets assigned to logical port SA0, use logical port SB0 as the redundant path. For targets assigned to logical port SA1, use logical port SB1 as the redundant path.

The following steps are a summary of the steps included in Creating target portal groups and Assigning

portals to the portal group, but are for establishing a redundant path:

1. Create a portal group by selecting Target > Create Portal Group. Assign a name to the redundant

portal group.

Security tasks

Security can include one or all of the following:

• Setting up Access Control Lists

• Setting up CHAP authentication

• Setting the SSL certiﬁcate

Setting up Access Control Lists

Access control lists (ACLs) provide security at the LUN level. In an ACL, you indicate the initiator(s) that can access speciﬁc mapped logical drive units of a target.

NOTE:

Repeat all steps in this section for each target for which you want to establish an ACL.

1. From the server, open the iSCSI initiator software and close any active connections to the target. This

ensures that there is no I/O activity on the target.

HP Storage Management Utility user guide

Page 52

2. Select Target > Enable/Disable Access Control.

3. Expand the

ACL State drop-down box, and enable access control.

4. The following warning message is displayed:

5. Conﬁrm that there is no active I/O on the target, and then click OK.

IMPORTANT:

• To prevent loss of access to the storage, ACLs should not be modiﬁed if there is an active session between the initiator and the target. Before enabling ACL for a target, open your iSCSI initiator software and verify that the target status is inactive or disconnected.

• When access control is

disabled

(default), all initiators with access to the array controller can access the storage targets. (If CHAP authentication is set up, only initiators with veriﬁed CHAP secrets can access the storage.)

• When access control is

enabled

, access to all mapped logical drives of the target is immediately blocked (Step 2 through Step 3), until ACLs are created for each mapped logical drive (Step 6 through Step 7).

Conﬁgure

Page 53

6. Select Mapped Logical Drive > Update Access Control.

NOTE:

Update Access Control is listed as a common task only if Access Control is enabled (Step 2).

7. Select the initiators that can access this mapped logical drive.

8. Repeat Step 6 through Step 7 for each mapped logical drive of the target.

9. If necessary, repeat Step 1 through Step 8 to set up an ACL for a different target.

Setting up CHAP authentication

The Challenge Handshake Authentication Protocol (CHAP) is one method of protecting access to the storage. When using CHAP, the same password (also called secret) is entered in both the storage management software and the initiator software.

When an initiator attempts to access the target, the CHAP secrets stored in both software utilities are compared. If the secrets match, access is granted. If the secrets do not match, access is denied.

Three methods of CHAP authentication are available. Choose one method:

• Setting up storage-system target discovery CHAP authentication

• Setting up target-speciﬁc initiator-to-target CHAP authentication

• Setting up mutual CHAP authentication

Setting up storage-system target discovery CHAP authentication

Creating a CHAP secret that allows discovery of all targets in the storage system requires two steps:

• Assigning a CHAP secret that applies to the storage system (Step 1).

• Entering the same CHAP secret in the iSCSI initiator software (Step 4).

Setting the SSL certiﬁcate

ASecureSocketsLayer(SSL)certiﬁcate provides browser security, ensuring a secure connection between the array controller and an initiating server, over which any amount of data can be sent securely. SSL works by using a private key to encrypt data transferred over the internet.

The array controller ships with a default certiﬁcate already installed, but until a server-speciﬁc certiﬁcate is installed, a warning message is displayed when accessing the SMU.

SSL certiﬁcate implementation on the MSA1510i makes use of PEM formatted ﬁles. Microsoft Certiﬁcate

ces do not directly support the PEM ﬁle format, but the publicly available OpenSSL toolset is

Servi recommended for generating required keys and certiﬁcates or for converting Microsoft private key exports into PEM format. For more information, see the HP Storageworks Modular Smart Array 1510i Advanced Planning and Conﬁguration Guide.

IMPORTANT:

• Completion time of an array expansion, logical drive extension, or logical drive migration varies,

depending on the drive speed and type, system array controller settings, and existing storage conﬁguration. (Process times of 36 to 72 hours are common.)

• During an expansion, extension, or migration, access to the data is permitted, but at a reduced

performance rate.

• During an expansion, extension, or migration, the risk of data loss if a drive fails is increased.

• Only one expansion, extension, or migration process can take place at a time.

• To verify the progress status of an expansion, extension, or migration:

•Viewtheiconforthelogicaldrive.

• View the More Information task for the logical drive.

• View the Status Alerts messages.

Disabling the array accelerator (Array Accelerator Settings)

By default, the array accelerator is enabled for all logical drives. To choose which logical drives use the array accelerator, select the top-level storage system from the system component list, and then select the Array Accelerator Settings task. Then, select which logical drives will use the array accelerator.

NOTE:

Disabling the array accelerator for a logical drive reserves use of the cache for other logical drives on the array. This feature is useful if you want the other logical drives to have the maximum possible performance.

Expanding an array (Expand Array)

If unassigned physical hard drives are available or were recently added to a storage enclosure, you can use this task to increase the storage capacity of an existing array.

After expanding an array to include the new hard drive(s), you can then use the additional storage capacity to:

HP Storage Management Utility user guide

• Create new logical drives on the array. (For more information, see

“Creating logical drives” on page 41.)

• Migrate the RAID level or stripe size of existing logical drives on the array (For more information,

see“Migrating to a different RAID level or stripe size (Migrate RAID/Stripe Size)”onpage60.)

• Extend the storage capacity of an existing logical drive on the array. ((For more information, see

“Extending a logical drive (Extend Logical Drive)” on page 60.)

To expand the capacity of an array:

1. Ensure that a known, good backup of the array is available.

2. Verify that the Expand Priority is set to Medium or High. (For more information, see

“Changing global settings (Storage System Settings)” on page 61.)

4. Select the physical hard drives to add to the array.

Extending a logical drive (Extend Logical Drive)

If unused space is available in an array, you can use this task to increase the storage capacity of an existing logical drive on that array.

NOTE:

The Extend Logical Drive task is listed only if unused space is present in the logical drive's array. To create unused, available space in the array:

•

2. Enter the new values.

NOTE:

• The Cache Ratio determines the amount of memory allocated to read and write operations. For improved performance, you may want to change this ratio to allocate more memory to write operations, as high as 10% read/90% write.

•TheExpand/Rebuild Priority settings determine whether normal operations are affected by an expansion or rebuild—changing these settings from the defaults may affect system performance:

• A low priority has a minimal effect on normal operations, because the expansion

or rebuild process takes place only when the controller is not busy. However, there is an increased risk of data loss if another physical drive fails before the process is completed.

• A high priority has a greater effect on normal operations, because the expansion

or rebuild process has a higher priority than the normal operations. With more system resources allocated to the expansion or rebuild process, the completion time is reduced, also reducing the risk of data loss if another physical drive fails before the process is completed.

• Before initiating an array expansion or logical drive extension, HP recommends

changing the corresponding priority setting to Medium or High.

4Wizards

The Initial System Conﬁguration Wizard is the easiest and simplest method to initially conﬁgure your system. You are prompted in a logical sequence for storage, iSCSI, logon, and management settings. The wizard then uses those settings to conﬁgure the storage as an iSCSI target and make it available to the iSCSI initiator.

NOTE:

This conﬁguration method is best for single-server environments needing bulk storage:

• One IP address is assigned to each data port.

• One target is created.

• One initiator is identiﬁed.

For more control over an initial conﬁguration or to make changes to an existing conﬁguration, use the SMU Conﬁgure tab. (See “Conﬁgure” on page 25.)

• Updating MSA ﬁ

• Updating hard drive ﬁrmware

rmware

Figure 14 Update tab—task listing

Prerequisites

Before updating system ﬁrmware,makenoteofthefollowing:

• When determining which MSA controller ﬁrmware version to use, review the requirements and

information in the Compatibility Matrix(es), release notes, and other MSA announcements.

• Because ﬁrmware updates require least one restart of the MSA array and its attached storage

enclosures, update system ﬁrmware only during a scheduled maintenance window.

• Before updating system ﬁrmware, stop all host trafﬁc to the array controller.

• Before updating system ﬁrmware, make sure that a recent, known good backup of all data on

the MSA array is available.

• Before updating system ﬁrmware,makesurethatacopyoftheconﬁguration, including the iSCSI

IP addressing and portal information, along with the hard drive, LUN, and target information is available.

HP Storage Management Utility user guide

Page 80

• If it has been more than six months since you restarted your MSA storage system, HP recommends

that you power-cycle the MSA (power off, and then power on) before updating the ﬁrmware to ensure that you are working with a fresh system.

• For newly installed MSA, do not perform a ﬁrmware update until controller batteries are fully

charged.

• For existing MSA, do not perform a ﬁrmware update until you have conﬁrmed that the “host

mode” or “proﬁle” for each connection is correctly set. The host mode identiﬁes the operating system of each connection to the storage. Do not use the “default” setting. If the host mode is not properly set, hosts may lose access to the storage or experience other difﬁculties after the update. Depending on your operating system environment or user preference, the host mode is set through the “connection” commands of the CLI or through the “ACL” settings of the SMU. For more information, see the CLI or SMU user documents.

• In dual controller MSA1510i conﬁgurations, you MUST log off all redundant paths to the MSA

array prior to beginning a ﬁrmware update. The update will not succeed if redundant paths are detected by the MPIO/DSM and may require multiple reboots to recover back to the original ﬁrmware version. There could also be potential loss of connection of the Internet Explorer to the management port if there are redundant paths during the ﬂash update cycle.

• In dual controller MSA1510i conﬁgurations, only one of the two MSA controllers is updated

directly. The second MSA controller is updated (cloned) when the MSA is power-cycled near the end of the updating procedure.

• Depending on the storage enclosure model attached to the MSA array (SATA or SCSI), you may

be able to update enclosure ﬁrmware or hard drive ﬁrmware through the MSA utility.

• After the update is complete, be sure to check the status of the MSA for unexpected issues.

After power-cycling the MSA array, verify the status of the connections, deﬁned proﬁle types, redundancy settings, and storage conﬁguration.

• After the update is complete, power cycle the MSA and all of its attached hard drive storage

enclosures to activate the new ﬁrmware.

IMPORTANT:

If you encounter any problems during the ﬁrmware update process, stop and contact HP technical support. See “HP technical support” on page 11 for support contact information.

Updating MSA ﬁrmware

1. Determine which version ﬁrmware is currently installed on the MSA by using one of the following

methods:

• With the array controller powered on, press the arrow buttons on the front of the controller until the following message is displayed: 00 Array Controller Firmware ver <version>.

In dual-controller conﬁgurations, ﬁrmware on the two controllers is compared each time the MSA chassis is restarted. If the versions are mismatched, the system prompts to clone the ﬁrmware on the controller with the latest version over to the controller with the earlier version ﬁrmware. (For the system to operate in a dual-controller mode, ﬁrmware on the controllers must match.)

The following message is displayed on the LCD panel of the controller with the earlier ﬁrmware:

07 CLONE FIRMWARE ? ‘<‘ = NO, ‘>’ = YES

Press the > button on the LCD panel to clone the ﬁrmware. During the cloning process, informational messages are displayed on the controller LCD panels. When the cloning process is complete, the just-updated controller automatically restarts.

Updating hard drive ﬁrmware

SCSI hard drive ﬁrmware updates are performed using ﬁles on the ProLiant Firmware Maintenance CD and are required only when the following message is displayed on the MSA controller LCD panel:

85 BAD DRIVE FRMWARE BOX <n> BAY <n>

CAUTION:

Before downloading new ﬁrmware,makenoteofthefollowing:

• Update system ﬁrmware during a scheduled maintenance window.

• Stop all host trafﬁc to the array controller during the updating process.

• Make sure that a recent, known good back up of all data on the MSA array is available before

updating system ﬁrmware.

• Make sure that a copy of the conﬁguration, including the iSCSI IP addressing and portal information,

along with the hard drive, LUN, and target information is available before updating system ﬁrmware.

• If it has been more than six months since you restarted your MSA storage system, HP recommends

that you power-cycle the MSA (power off, and then power on) before updating the ﬁrmware to ensure that you are working with a fresh system.

• After the update is complete, power cycle the MSA and all of its attached hard drive storage

enclosures to activate the new ﬁrmware.

• For newly installed MSA, do not perform a ﬁrmware update until the controller batteries are fully

charged.

Arrays and logical drives

The capacity and performance of a single physical hard drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when a hard drive fails.

Connecting extra physical drives to a system increases the total storage capacity (Figure 15), but has no effect on the efﬁciency of read/write operations. Data is still transferred to only one physical drive at a time.

D1 D2 D3

15310

Figure 15 Multiple physical drives (D1, D2, and D3) in a system

An array controller combines several physical drives into one or more virtual units called logical drives, which have superior performance, capacity, and/or fault tolerant features than separate physical drives. The read require

/write heads of all included physical drives are active simultaneously, reducing the total time

d for data transfer.

R/W

D1 D2 D3

15311

Figure 16 Multiple physical drives (D1, D2, and D3) conﬁgured into one logical drive (L1)

Because the read/write heads are active simultaneously, the same amount of data is written to each drive

g any given time interval. Each unit of data is called a block, and adjacent blocks form a set of

durin data stripes across all physical drives in that logical drive (Figure 17).

D2D1 D3

15312

Figure 17 Data striping (S1-S4) and data blocks (B1-B12) on multiple physical drives (D1, D2, D3)

For data in the logical drive to be readable, the data block sequence must be the same in every stripe. This sequencing process is performed by the array controller, which sends the data blocks to the drive write heads in the correct order.

A natural consequence of the striping process is that each physical drive in a given logical drive will contain the same amount of usable space. If one physical drive has a larger capacity than other physical drives in the same logical drive, the extra capacity is wasted, because it cannot be used by the logical drive.

The group of physical drives containing the logical drive is called a drive array (or just array). Because all physical drives in an array are commonly conﬁgured into just one logical drive, the term array is also often used as a synonym for logical drive. However, an array can contain several logical drives, each of adifferentsize(Figure 18).

D1 D2 D3 D4 D5

Figure 18 Two arrays (A1, A2) containing ﬁve logical drives (L1 through L5) spread across ﬁve physical drives (D1 through D5)

Each logical drive in an array is distributed across all of the physical drives within the array. A logical drive can also extend across more than one storage enclosure attached to the array system.

Drive failure, although rare, is potentially catastrophic. For example, in Figure 18, failure of any one physical drive in an array causes every logical drive in the array to suffer irretrievable data loss.

To protect against data loss due to physical drive failure, logical drives are usually conﬁgured with fault tolerance.

Fault-tolerance levels

To protect against data loss due to physical drive failure, logical drives are usually conﬁgured with fault tolerance. The following conﬁguration types are available:

•RAID0—nofaulttolerance

• RAID 1+0—drive mirroring

• RAID 5—distributed data guarding

• RAID 6—advanced data guarding

15313

For any conﬁ guration except RAID 0, further protection against data loss can be achieved by assigning a drive as an online spare. This drive contains no data and is connected to the same controller as the array. When any other physical drive in the array fails, the controller automatically rebuilds information

86 Storage overview

Page 87

that was originally on the failed drive to the online spare. The system is quickly restored to full RAID-level data protection. (In the unlikely event that another drive in the array fails while data is being rewritten to the spare, the logical drive will still fail.)

A spare is assigned to an array and is automatically assigned to all logical drives in the same array. You do not need to assign a separate spare to each array; you can conﬁgure one hard drive to be the spare for several arrays.

RAID 0—no fau

lt tolerance

This conﬁguration (Figure 17) provides no protection against data loss when a drive fails. However, it is useful for rapid storage of large amounts of non-critical data (for printing or image editing, for example), or when cost is the most important consideration.

Table 3 RAID 0

features

Advantages Disadvantages

Highest performance method for writes.

Lowest cost per unit of stored data. All drive capacity is used to store data (none needed

for fault tolerance).

RAID 1+0—drive mirroring

In this conﬁguration, data on a physical hard drive is duplicated to a second hard drive.

NOTE:

When only two hard drives are included in the array, this fault-tolerance method is called RAID 1. When more than two hard drives are included in the array, this fault-tolerance method is called RAID 1+0. (RAID_1 is not supported on the MSA1510i storage system.)

Alldataonthelogicaldriveislostifaphysicaldrive fails.

Cannot use a spare. Can only preserve data by backing it up to external

storage media.

D1 D2

15314

Figure 19 RAID 1 array, with two physical hard drives (D1, D2)

When the array has more than two physical drives, drives are mirrored in pairs (Figure 20).

HP Storage Management Utility user guide

Page 88

15315

Figure 20 RAID 1+0 array, with eight physical hard drives (D1 through D8)

In each mirrored pair, the physical drive that is not busy answering other requests answers any read request sent to the array. (This behavior is called load balancing.) If a physical drive fails, the remaining drive in the mirrored pair can still provide all the necessary data. Several drives in the array can fail without incurring data loss, as long as no two failed drives belong to the same mirrored pair.

RAID 1+0 is useful when high performance and data protection are more important than the cost of physical drives.

Table 4 RAID 1, RAID 1+0 features

Advantages Disadvantages

Highest read and write performance of any

lerant conﬁguration.

fault-to No loss of data as long as no failed drive is mirrored

to another failed drive.

Expensive (half of the drives are used for fault tolerance).

Only half of total drive capacity usable for data storage.

RAID 5—distributed data guarding

In this method, a block of parity data is calculated for each stripe from the data that is in all other blocks within that stripe. The blocks of parity data are distributed across every physical drive within the logical drive (Figure 21).Whenaphysicaldrivefails,datathatwasonthefaileddrivecanbecalculatedfrom the dat or to a replacement drive in a process called a rebuild.

Table 5 RAID 5 features

Advantages Disadvantages

High read performance. Relatively low write performance.

No loss of data if one physical drive fails.

More usable drive capacity than RAID 1+0, because parity information requires the storage space equivalent to one physical drive.

RAID 6—advanced data guarding

RAID 6 (also called RAID ADG) is similar to RAID 5, because both methods generate and store parity information to protect against data loss caused by drive failure. With RAID 6, however, two different sets of parity data are distributed across the physical drives, allowing data to be preserved even if two drives fail. Each set of parity data uses up a capacity equivalent to that of one of the constituent drives, as shown in Figure 22.

This method is most useful when data loss is unacceptable, but cost is also an important factor. The probability that data loss will occur when arrays are conﬁgured with RAID 6 (ADG) is less than when they are conﬁgured with RAID 5.

Table 6 RAID 6 (ADG) features

Advantages Disadvantages

High read performance.

High data availability—Any two drives can fail without loss of critical data.

More drive capacity is usable than with RAID 1+0—Parity information requires only the storage equivalent to two physical drives.

Relatively low write performance (lower than RAID 5), because of the need to create two sets of parity data.
