About this guide

1 All-in-O ne Storage Manager

All-in-One Storage Manager

HP StorageWorks All-in-One Storage M anager (ASM) is a storage hosting and management tool that radically simpliﬁes:

•

Hosting storage for applications and shared folders, page 19

•

Conﬁguring data protection, page 37

•

Managing storage,page43

•

Monitoring storage,page47

ASM provides storage-allocation wizards that walk you through the process of allocating and conﬁguring storage on your HP All-in-One Storage System to host application data and shared folders. The storage-allocation wizards also allow you to schedule backups and snapshots of hosted application data and shared folders.

Other wizards are provided to help you set up SQL Server database storage, storage for user-deﬁned applications, and storage for shared folders.

ASM is designed to work seamlessly with Windows administrator tools, the HP All-in-One Storage System Management application, Microsoft iSCSI Target, and Data Protector Express. For example, you can change your HP All-in-One Storage System’s:

• Storage allocations ( quotas), shared folder permissions and names, and snapshot schedules

using ASM, Windows administrator tools, and the HP All-in-One Storage System Management applications.

• Med ia rotation type using ASM and Data Protector Express.

However, you should not use Windows administrator tools to change the paths to storage conﬁgured on your HP All-in-One Storage System or ﬁle directories created by ASM on application servers with storage hosted on your HP All-in-One Storage System. Doing so will break the iSCSI communication paths between your application servers and HP All-in-One Storage System, and make it so ASM can no longer locate allocated storage areas on your HP All-in-O ne Storage System.

Software requirements

Software support

Only storage for application servers running on Windows Server 2003 and on the same domain as your HP All-in-One Storage System can be hosted.

ASM provides storage-management services for the following applications:

mes preinstalled on your HP All-in-One Storage System. A license key is not required for ASM.

Microsoft SQL Server 2000 and 2005

User-deﬁned applications

Microsoft iSCSI Target and Data Protector Express are required to host application storage and create backups using ASM. Microsoft iSCSI Target and Data Protector Express come preinstalled on your HP All-in-One Storage System. A license key is not required for Microsoft iSCSI Target. Your license key for Data Protec

tor Express comes preinstalled on your HP All-in-One Storage System.

Storage management infrastructure

The purpose of ASM is to simplify storage management, so that you do not need to understand the complexities of allocating and conﬁguring storage, and hosting application storage on your HP All-in-One Storage System. ASM handles two types of use models:

• M anaging storage for application servers,page12

•

Managing storage for shared folders, page 13

Managing storage for application servers

With ASM, you can allocate, conﬁgure, and host storage for applications residing on servers that hostExchange,SQLServer,anduser-deﬁned applications using the Host an Exchange Storage Group Wizard, Host a SQL Server Database Wizard, and Host a User-Deﬁned Application Wizard.

The wizards suggest a default storage size, plus default advanced conﬁguration settings, such as RAID level, for each application component. You can customize all the defaults to ﬁtyourstorageneeds. However, the default advanced settings provided for Exchange and SQL Server are based on HP storage, Exchan

ge, and SQL Server best practices and should generally not be changed.

Wizard”onpage21.

Wizard”onpa

Wizard”onpage24.

ge 22.

For app stora

lication storage, ASM creates an iSCSI LUN on your HP All-in-One Storage System for each

ge group component, database component, or the user-deﬁned application you select to host in the storage-allocation wizard, and exports it to the application server whose storage will be hosted. ASM also creates a LUN on your HP All-in-One Storage System to host the storage group component, database component, or the user-deﬁned application you selected in the storage-allocation wizard. All storage

unication passes through the iSCSI LUN on the application server to the LUN on your HP All-in-One

comm Storage System. This allows data saved by the application to the iSCSI LUN on the application server to be automatically saved to your HP All-in-One Storage System instead (see Figure 1).

All-in-One Storage Manager

Figure 1 App

NOTE:

The iSCSI communication path is transparent to the application, application server, and Windows Explorer. The application, application server, and Windows Explorer believe the data is stored on the applicati application server, not the LUN(s) on your HP All-in-One Storage System, using Windows Explorer.

ASM provides automated data migration for Exchange and SQL Server. ASM discovers Exchange storage group an d SQL Server database components and hosts the storage components you select through the storage-allocation wizards. ASM automatically migrates the data for the selected storage components to your HP All-in-One Storage System. ASM a lso conﬁgures the application to read and write data for the hosted storage component to the iSCSI LUNs created on the application server by ASM.

ASM does not provide automated data migration for user-deﬁned application servers. You must manually migrate the application data to your HP All-in-One Storage System after using the H ost a User-Deﬁned Application Wizard to allocate and conﬁgure storage space. See “Migrating user-deﬁned application data to your HP All-in -One Storage System” on page 34 for more information. You must also conﬁgure the application to read and write data to the iSCSI LUN created on the application ser ver by ASM. See the application’s documentation for more i nformation.

lication storage infrastructure

Managing storage for shared folders

With ASM, you can set up and monitor top-level shared folders (ﬁle shares) using the Create a Shared Folder Wizard. The wizard suggests a default storage size for each shared folder, plus default advanced conﬁguration settings, such as RAID level. You can customize all the defaults to ﬁtyourstorageneeds.

For shared folder storage, ASM creates a LUN on your H P All-in-One Storage System to hold the shared folder and then creates the shared folder (see Figure 2). Shared folders whose storage is conﬁgured with the same RAI D level are created on the same LUN.

All-in-One Storage Manager

Figure 2 Shared folder storage infrastructure

ASM discovers any top-level and nested shared folders on your HP All-in-One Storage System during setup and afterwards on an ongoing basis. ASM allows you to m onitor and manage any top-level shared folders created on your HP All-in-One Storage System using ASM or other applications, such as Windows Explorer or the Shared Folder MMC snap-in.

After s hared folders are created, communication between client and host takes place over the Common Internet File System (CIFS) protocol.

Nested shared folders, which are shared folders that reside inside top-level shared folders, cannot be created using ASM, but can be viewed in ASM by selecting the top-level shared folder in the content pane and then clicking Properties in the Action pane. Use other applications, such as Windows Explorer or the Shared Folder MMC snap-in, to create nested shared folders on your HP All-in-One Storage System.

Using the Host a User-Deﬁned Application Wizard

The wizard helps you set up your All-in-One Storage System to store application data for various applications. Storage will be allocated for the application, optionally exposed to another server using the iSCSI protocol, and an NTFS ﬁle volume may be optionally created on the remote application server. Upon completion, you can monitor and manage storage for the application through the the All-in-One Storage manager.

After storage is allocated and conﬁgured on your HP All-in-One Storage System for a remote application using the Host a User-Deﬁned Application Wizard, do the following:

• Manually migrate the remote application’s data to your H P All-in-One Storage System. See

“Migrating user-deﬁned application data to your HP All-in-One Storage System”onpage34 for more information.

• Conﬁgure the remote application to store its data on the iSCSI LUN exported by ASM to the

application server as described in the application’s documentation.

Before you begin conﬁguring storage for a user-deﬁned application

• Verify the remote application has the following characteristics:

• Runs under Windows Server 2003

•UsesNTFSvolumesforstorage

• Make sure the ASM agent is installed on each application server with data you plan to host. See

the HP StorageWorks All-in-One Storage System quick start instructions for more information.

• Make sure you have an up-to-date backup of your remote application data and logs.

• For an iSCSI LUN application, you will need the iSCSI qualiﬁed name.

NOTE:

For a remote windows application, you need to know the path to the iSCSI LUN on the application server to conﬁgure the remote application to store data on the iSCSI LUN. The path to the iSCSI LUN is displayed on the application’s Properties window on the Storage tab.

NOTE:

The Size Range column shows the minimum and maximum storage space that can be allocated to each application component, user-deﬁned application, or shared folder listed. Whenever you change the allocated space size or an advanced conﬁguration setting for an application component, the maximum value for Size Range is recalculated for all the application components listed.

NOTE:

To change the advanced conﬁguration settings for an application component, user-deﬁned application, or shared folder listed, select the item to edit and then click Advanced.See “Selecting advanced conﬁguration settings” on page 27 for more information.

2. When you are done selecting the storage allocation and conﬁguration settings, click Next to open

the summary page.

Hosting storage for applications and shared folders

NOTE:

After storage space is allocated and conﬁgured using a wizard, only the following storage conﬁguration settings can be changed:

• Allocated space size

• Percent full warning threshold

• Enforce Allocated Limit (shared folders only)

Once a logical disk is created, its conﬁguration cannot be changed.

Selecting advanced conﬁguration settings

Use the Advanced window in the wizard to change the allocated space size and default advanced conﬁguration settings for each application component, user-deﬁned application, and shared folder listed.

After storage is conﬁgured using a wizard, you can access the Advanced window from the Allocate Space Wizard and change the allocated space size, percent full threshold warning, and/or enforce allocated limit (shared folders only) values as needed.

NOTE:

When allocating storage on an AiO400 Storage System that does not have additional external storage, most of the default advanced conﬁguration settings cannot be changed. This is because the AiO400 Storage System is pre-conﬁgured with one volume a nd one logical disk, and ASM is unable to create any new logical disks on the system. All storage allocated is allocated from the existing logical disk.

Table 6 provides a brief description of the items you can modify:

NOTE:

Once the allocated storage space is full (100 percent used), no further data can be stored to the space until you increase the size using the Allocate Space Wizard. The only exception is for shared folders without an enforced allocated limit. If there is unused storage space on the logical disk where a shared folder without an enforced allocated limit resides, data can be written to the shared folder until the logical disk is full.

Unless you customize the advanced conﬁguration settings, the wizard conﬁgures the storage space with the default values shown on the Advanced window:

• For Exchange and SQL Server, the wizard suggests default settings based on HP storage best

practices and speciﬁc recommendations for Exchange storage group and SQL Server database components. You should generally accept these defaults.

Hosting storage for applications and shared folders

• For user-deﬁned applications and shared folders (where industry-standard recommendations

cannot be determined), the wizard provides default settings you can customize.

Table 7 shows how the different RAID levels affect:

• Performance–The speed at which data is read from and written to the hard drives. The RAID level

with the best performance rating provides the fastest reads and writes.

• Capacity–The available storage space on the hard drives. The RAID levels with the best capacity

rating require the least amount of storage space to store data.

• Da ta protection–The number of hard drives that can fail without data being lost. The RAID level

with the best data protection rating allows more hard drives to fail before data is lost.

For more information on the different RAID levels, see Table 7.

Table 7 D escriptions of RAID levels

RAID level

No RAID

RAID 0 – Striping (No Fault Tolerance)

RAID 1 – Mirroring

RAID 1+ 0 – Mirroring and Striping

Description

Offers no protection against disk failure. If a disk drive fails, data will be lost.

Offers the greatest capacity and performance without data protection. If you select this option, you will experience data loss if a hard drive that holds the data fails. However, because no logical drive capacity is used for redundant data, this method offers the best capacity. This method offers the best processing speed by reading two stripes on different hard drives at the same time and by not having a parity drive.

Offers a good combination of data protection and performance. RAID 1 or d rive mirroring creates fault tolerance by storing duplicate sets of data on a minimum of two hard drives. There must be an even number of drives for RAID 1. RAID 1 and RAID 1+0(10) are the most costly fault tolerance methods b ecause they require 50 percent of the drive capacity to store the redundant data. R AID 1 mirrors the contents of one hard drive in the array onto another. If either hard drive fails, the other hard drive provides a backup copy of the ﬁles and normal system operations are not interrupted.

Offers the best combination of data protection and performance. RAID 1+0 or drive mirroring creates fault tolerance by storing duplicate sets of data on a minimum of four hard drives. There must be an even number of drives for RAID 1+0. RAID 1+0(10) and RAID 1arethemostcostlyfaulttolerancemethodsbecausetheyrequire 50 percent of the drive capacity to store the redundant data. RAID 1+0(10) ﬁrst mirrors each drive in the array to another, and then stripes the data across the mirrored pair. If a physical drive fails, themirrordriveprovidesabackupcopyoftheﬁles and normal system operations are not interrupted. RAID 1+0(10) can withstand multiple simultaneous drive failures, as long as the failed drives are not mirrored to each other.

RAID 5 – Distributed Data Guarding

RAID 6– Advanced Data Guarding (ADG)

Offers the best combination of data protection and usable capacity while also improving performance over R AID 6. R AI D 5 stores parity data across all the physical drives in the array and allows more simultaneous read operations and higher performance than data guarding. If a drive fails, the controller uses the parity data and the data on the remaining drives to reconstruct data from the failed drive. The system continues operating with a slightly reduced performance until you replace the failed drive. RAID 5 can only withstand the loss of one drive without total array failure. It requires a n array with a minimum of three physical drives. Usable capacity is N-1 where N is the number of physical drives in the logical array.

Offers the best data protection and is an extension of RAID 5. RAID 6 uses multiple parity sets to store data and can therefore tolerate up to 2 drive failures simultaneously. RAID 6 requires a minimum of 4 drives and is available only if the controller h as an enabler. Writer

Setting a percent full warning threshold

To receive a warning alert when storage capacity reaches a speciﬁed limit, set the percent full warning threshold. You can set a warning threshold for any application component, user-deﬁned application, and shared folder that ASM manages.

By default, the warning threshold is set to 80%. To change it, enter a new percent value on the Advanced window.

After you set a warning threshold, ASM changes the status indicator for the application component, user-deﬁned application, or shared folder when this threshold has been surpassed. This is a warning only; no hard limits are enforced on storage capacity as a result of setting this value. The warning is visible in these places:

• A yellow warning icon appears on the application component, user-deﬁned application, or

shared folder icon in the c ontent pane.

• As an alert in the Properties window.

NOTE:

For shared folders, you can set an enforceable limit (or quota) for allocated storage, as well as a warning threshold. For more information, see Enforcing an allocated storage limit for shared folders.

Description

performance is lower than RAID 5 due to parity data updating on multiple drive two disks to fa the number of p

Enforcing an allocated storage limit for shared folders

ASMprovidesawaytoenforceanallocatedstoragelimitforasharedfolder. Ifenforced,thesystem does not allow the amount of allocated space for the shared folder to be exceeded.

If the capacity of the shared folder surpasses the percent full warning threshold and reaches the allocated space limit, the ﬁle folder status changes from Warning to Critical in the content pane, and users are blockedfromaddingdatatothissharedfolder.

NOTE:

If you do not choose to enforce an allocated storage limit for a sha red folder, the ASM status indicator still goes from to the shared folder as long as there is still unallocated storage space on the lo gical disk where the sharedfolderresides.

Migrating user-deﬁned application data to your HP All-in-One Storage System when using a remote windows application

For a remote windows application, the Host an Exchange Storage Group Wizard and Host a SQL Server D atabase Wizard automatically migrate application data from the application server to your HP All-in-OneStorageSystem. TheHostaUser-Deﬁned Application Wizard, however, does not migrate data for a user-deﬁned application from the application server to your H P All-in-One Storage System for a remote windows applications.You must do this manually.

1. Using ASM, determine the path to the iSCSI LUN (logical disk) created on the application server

by ASM, as follows:

a. Select the user-deﬁned application in the content pane.

b. Copy the application data and paste it to the application path on the application server

recorded in step 1. For example, if the ap plication data is stored on C:\application\data and the

application path you recorded is G:\application\data, copy and paste the data in C:\application\data to G:\application\data on the application server.

3. Delete the application data from the old path (optional).

Any data saved to the iSCSI LUN on the application server is now saved to a LUN on your H P All-in-One Storage System and not on the server.

NOTE:

Unallocated storage on a logical disk is re-allocated by ASM when new or additional storage is allocated to an application component or shared folder and the advanced conﬁguration values selected forthestoragematchesthoseofthelogicaldisk.

For example, if an application component or shared folder’s allocated storage is increased, any unallocated space on the logical disk where it resides is used before the logical disk grows.

Removing application areas from view

You can remove application components and user-deﬁned applications from view on the ASM user interface. This allows you to remove storage information from the content pane pertaining to storage allocations lost due to hard drive failure or storage for an application component or user-deﬁned application whose storage you plan to unhost.

Removing an application component or user-deﬁned application from view does not unhost its storage. Its storage is still hosted on your HP All-in-One Storage System. To permanently remove storage from your All-in-One storage system, you must ﬁrst remove the storage that is hosted by AiO. Depending on the type of storage ,see h information on how to remove different types of storage.

NOTE:

If you remove an application component or user-deﬁned application from view without unhosting the storage, your All-in-One Storage System will re-discover the applications immediately.

The unmanaged value is the total storage being used to store data not managed by ASM, such as application or shared folder data no longer managed by ASM because the application components or shared folder was removed from view (see “Removing application areas from view” on page 44) and any other data saved on your HP All-in-One Storage System that is not managed by ASM.

• Unallocated—Unused storage that is not allocated.

The unallocated space value is the total unused space on your HP All-in-One Storage System that has not been allocated to host application or shared folder storage. Unallocated storage includes raw (unconﬁgured) storage and unused conﬁgured storage (logical disks).

NOTE:

SQL Server errors

Host a SQL Server Database Wizard authentication error

Problem: While using the Host a SQL Server Database Wizard, you receive an error message informing you that ASM cannot authenticate with the server that hosts SQL Server.

Solution: Each SQL Server license (instance) must have a login for the local user called ASMUser with the server role deﬁned as System Administrators. This login is created during the installation of the ASM agent on the server that hosts SQL Server; however, if another SQL Server license is installed after the ASM agent is installed, this login will not be conﬁgured.

To ﬁx this problem, you can remove the ASM agent from the server that hosts SQL Server, and then reinstall it following the instructions in the HP StorageWorks All-in-One Storage System quick start instructions (no information will be lost). Or, manually enter the login as follows:

1. Open SQL Server Enterprise Manager.

2. Connect to the server with SQL Server data you want to store on your HP All-in-One Storage System.

3. Select the Security Folder.

4. Select Logins.

5. Select New Login.

6. In the Name ﬁeld, enter ASMUser.

7. In the Domain ﬁeld, enter the domain name for the server that hosts SQL Server.

8. Select the Server Roles tab.

9. Select the System Administrators server role and click OK.

array Also known as a JBOD (just a bunch of disks). A group of hard drives in an

enclosure (chassis) that are controlled by an array controller.

array controller Controls reads and writes to the hard drives in an array.

backups A read-only copy of data copied to media, such as hard drives or magnetic

tape, for data p rotection. A full backup copies all the data selected to be backed up. An incremental backup copies only data selected to be backed up that has changed since the last full backup. Backups provide data protection in the event of system or hard drive failure, because the data is stored on media separate from the system hard drives.

data protection Protects data from being corrupted or lost as a result of hard drive failure.

Methods used to provide data protection include RAID and b ackups.

All-in-One Storage Manager

enforce allocated limit (quota)

An enforced quota for the amount of storage available to a shared folder. An enforce allocated limit prevents data from being saved to a shared folder once all the storage space allocated to the shared folder is used.

Exchange storage group

The fundamental unit of storage mana gement in Microsoft Exchange. Storage groups consist of Mail stores, Public stores, and log ﬁles.

exclusive storage An Advanced window option that allows you to dedicate a hard drive(s) for

storing data for a speciﬁc application component or shared folder.

ﬁle system A method for storing and organizing computer ﬁles and the data they contain to

make it easy to ﬁnd and access them.

hot spares An Advanced window option that allows you to reserve one or two hard drives

as spares. A hot spare is a hard drive reserved as a spare for storage space conﬁgured as RA ID 1, RAID 1+0(10) , or 5. A hot spare automatically replaces aharddrivewhenitfails.

iSCSI Internet small computer system interface. Like an ordinary SCSI interface, iSCSI

is standards-based and efﬁciently transmits block-level data bet ween a host computer (such as a server that hosts Exchange or SQL Server) and a target device (such as an HP All-in-One Storage System). By carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. ASM works with the Microsoft iSCSI Target, which builds the iSCSI infrastructure on application servers with data hosted on your HP All-in-One Storage System and on your HP All-in-One Storage System so that application data is stored on your HP All-in-One Storage System.

iSCSI LUN A type of LUN (logical disk) created on an application server by ASM when a

storage-allocation wizard is ran to host application storage. When application storage is hosted using ASM, all storage communication passes through the iSCSI LUN on the application server to the LUN on your HP All-in-One Storage System. This allows data saved by the application to the iSCSI LUN on the application server to be transparently stored on your HP All-in-One Storage System instead.

log ﬁle The component of a Microsoft Exchange storage group or a Microsoft SQL

Server database that contains log data.

logical disk Also known as a LUN. A logical disk contains one or more volumes and spans

multiple hard drives in an array. RAID conﬁguration of storage is performed at the logical disk level.

LUN Also known as a logical disk. ASM will grow a LUN (make it larger) when the

LUN requires more of the storage space on an array.

Mail store The component of a Microsoft Exchange storage group that contains mailbox

data.

Menu bar The horizontal menu located at the top of the ASM user interface. The menu bar

is the Microsoft Management Console menu bar; ASM is a snap-in hosted by the Microsoft Management Console.

MMC snap-in Microsoft Management Console snap-in. An application added to the Microsoft

Management Console. All-in-One Storage Manager is a MMC snap-in.

NAS Network-attached storage. This term is used to refer to a specialized type of

ﬁle server. The HP All-in-One Storage System provides NAS storage as well as iSCSI storage.

NFS Network ﬁle system. The protocol used in most Unix environments to share

folders or mounts. The Create a Shared Folder Wizard does not create NFS shares, but NFS shares can be created using the Shared Folder MMC snap-in.

percent full warning t hreshold

Percentage of capacity for a storage area (storage a llocated to an application component or shared folder) at which an alert is generated. This alert is displayed in the Content pane and sent to the Windows Event Log. See

Setting a percent full warning threshold on page 30 for more information.

Public store The component of a Microsoft Exchange storage group that contains public

folder data.

RAID Redundant array of intelligent disks. Two or more hard drives conﬁgured to

provide a storage with resilience to hard drive failure through the use of R A I D striping and parity d isks.

component or shared folder. To change the size of the allocated storage for an application component or shared folder, select the application component or shared folder in the Content pane and then select Allocate Space in the Actions pane.

snapshot A read-only copy of a volume at a speciﬁc point in time. Unlike a backup, data

is not copied to any media during a snapshot. Instead, when a ﬁle is modiﬁed after a snapshot is created, the new updates are written to a new location. The ﬁle-system maintains records and pointers to keep track of the snapshot data and ﬁle changes. A snapshot takes less than a second to create.
