1 All-in-One Storage Manager
HP StorageWorks All-in-One Storage Manager (ASM) is a storage hosting and management tool that
radically simplifies:
• Hosting storage for applications and shared folders, page 11
• Data protection, page 31
• Managing storage, page 41
• Monitoring storage, page 45
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, snapshots, and replication of
hosted application data and shared folders.
Other wizards are provided to help you set up Exchange Server storage, 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.
• Media 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-One Storage System.
Software requirements
ASM comes preinstalled on your HP All-in-One Storage System. A license key is not required for ASM.
Software support
Storage for application servers running on Windows Server 2003 with SP1 and Windows Server
2008 that are on the same domain as your HP All-in-One Storage System can be hosted. Windows
domain controllers (such as Windows Small Business Server) are supported by ASM as managed
application servers.
HP StorageWorks All-in-One Storage Manager 7
ASM provides storage-management services for the following applications:
Table 1 Software support
Microsoft Exchange Server 2003 with SP1 or later
and Exchange Server 2007
File sharing services on local storage
Microsoft SQL Server 2000 with SP4 or later, SQL
Server 2005 with SP2 or later, and SQL Server
2008*
User-defined applications
* ASM does not support SQL Server 2008 databases that utilize FILESTREAM data type storage.
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 Protector Express comes preinstalled on your HP All-in-One Storage System.

2. Select an item in the Items list and a color in the Color drop-down menu.
3. When your color selections are complete, click Apply to apply the color settings to the content
pane.
4. Click OK.
Scaling display settings
Changing the scaling settings customizes the size at which each application area or shared folder is
displayed in the content pane. You can choose to scale each application area and shared folder so
that it is displayed in proportion to its capacity (allocated storage size), or so that all the application
areas and shared folders are displayed at the same size.
1. In the Actions pane, click Configure Display Options.
The Display Options dialog box opens.
2. Click the Scaling tab.
3. Select the storage-display proportion setting:
• According to capacity, using automatic scaling—Displays logical disks and volumes, and
application areas according to relative size, but leaves the display readable.
• All as the same size—Displays logical disks and volumes, and application areas as the same
size.
4. Click Apply to apply your change.
5. Click OK.
Configure Application Credentials
Use the Application Credentials dialog box to set or update user name and password security
credentials applicable to the All-in-One Storage System.
1. Expand the nodes of the tree in order to view the credential status of an application server.
2. If the Credential Status column reads OK or Not required, no action is required for that application.
3. If the Credential Status column reads Failed or Not set, select the application row and then click
Update Credentials. An Enter Credentials dialog box is displayed.
4. Type the user name and password of a user with sufficient privileges as described in the dialog
and then click OK.
5. Repeat steps 1 through 4 for each application server.
Configure Storage Networks
Use the Storage Networks dialog box to configure a preferred private storage network for iSCSI traffic
between your All-in-One Storage System and any connected servers that use the iSCSI protocol. This
dialog box appears the first time you use the Host an Exchange Storage Group wizard, Host a SQL
Server Database wizard, or Host a User-Defined Application wizard. Settings configured in this dialog
box affect only iSCSI traffic.
HP strongly recommends configuring all iSCSI-based storage for application servers on a dedicated
Ethernet subnet. The purpose of a private LAN for iSCSI traffic is to is to guarantee dedicated network
bandwidth for storage as well as increased security.
HP StorageWorks All-in-One Storage Manager 9
To configure storage networks for iSCSI traffic:
1. Under Preferred Storage Network, select a network that will be designated to manage all iSCSI
traffic.
2. Under Available for Failover, select a network that can be used to manage iSCSI traffic in the
event that the preferred storage network fails. In the event of iSCSI initiator failure, iSCSI traffic
fails over to the designated network.
NOTE:
Any existing iSCSI connections must be reset before changes take effect.
Resetting iSCSI connections
If you use the Storage Networks dialog box to configure a preferred private storage network for iSCSI
traffic and there are one or more existing iSCSI connections on the system, the new setting will not
take effect until the existing connections are reset through iSCSI Initiator on the connected systems.
To reset an iSCSI connection:
1. On the system that contains the iSCSI initiator whose connection has been changed, open
Microsoft iSCSI Initiator.
2. On the Persistent Targets tab, select the iSCSI target that resides on your AiO Storage System
and then click Remove.
3. On the Targets tab, select the iSCSI target that resides on your AiO Storage System and then
click Details.
4. Select the target identifier from the list, click Log off, and then click OK.
5. On the Discovery tab, under Target Portals select the IP address that was previously designated
for iSCSI traffic between the application server and the All-in-One Storage System and click
Remove.
6. Click Add. In the IP address or DNS name field, type the IP address that was enabled for iSCSI
traffic in the All-in-One Storage Networks dialog box and then click OK.
7. On the Targets tab, click Log On.
8. Check the Automatically restore this connection when the system boots check box and then click
OK.
9. Click OK to close the iSCSI Initiator Properties dialog box.

2 Hosting storage for applications and
shared folders
The All-in-One Storage Manager (ASM) radically simplifies hosting application storage and shared
folders on your HP All-in-One Storage System, using storage-allocation wizards. Use storage-allocation
wizards to allocate and configure storage for these applications:
NotesDescriptionApplication
Allocate and configure storage for one
or more Exchange storage group
components. A wizard assists you by
discovering Exchange storage group
components (such as mail stores, public
Exchange
stores, and logs), suggesting default
storage configurations based on best
practices for Exchange, migrating the
Exchange storage group components you
selected to your HP All-in-One Storage
System, and configuring Exchange to
store data on your HP All-in-One Storage
System.
See “Using the Host an Exchange Storage
Group Wizard” on page 12 .
Shared Folders
SQL Server
Create shared folders on your HP
All-in-One Storage System. A wizard
assists you in allocating and configuring
storage space for shared folders, and
creating shared folders.
Allocate and configure storage for SQL
Server databases. A wizard assists you
by discovering servers that host SQL
Server and SQL Server database
components (such as data files and logs),
suggesting default storage configurations
based on best practices for SQL Server,
migrating the SQL Server database
components you selected to your HP
All-in-One Storage System, optionally
deleting the SQL Server database
components you selected from the server
that hosts SQL Server, and configuring
SQL Server to store data on your HP
All-in-One Storage System.
See “Using the Create a Shared Folder
Wizard” on page 14 .
See “Using the Host a SQL Server
Database Wizard” on page 15.

User-Defined
Applications
Data Protection
Allocate and configure storage for any
remote application over the iSCSI
protocol or any other application that
requires storage on the All-in-One Storage
System. A wizard assists you in allocating
and configuring storage space.
The wizard does not migrate user-defined
application data to your HP All-in-One
Storage System or reconfigure the
application to store data on your HP
All-in-One Storage System. You must do
this manually as described in “Migrating
user-defined application data from a
remote application” on page 30, and as
described in the application's
documentation.

Upon completion, you can monitor and manage storage for the application through 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 HP All-in-One Storage System. See
“Migrating user-defined application data from a remote application” on page 30 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
• Make sure the ASM agent is installed on each application server with data you plan to host.
• Make sure you have a current 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.
To access the Host a User-Defined Application Wizard
1. In the Actions pane, select Host a User-Defined Application.
The Host a User-Defined Application Wizard welcome page opens.
2. Click Next to open the Choose type of Application page (see
“Choose type of application” on page 18).
Choose type of application
1. Select the type of application for hosting a user-defined application:
• Remote Windows Application- ASM will provision storage for the application and expose
the storage to the given server as an NTFS volume over the iSCSI protocol. This is the
Hosting storage for applications and shared folders18
recommended option for most scenarios. The All-in-One Storage Manager agent must be
installed on the application server to use this option.
• iSCSI LUN- Exposes a LUN to the remote server so the server can store data on the LUN. You
will need to install an iSCSI initiator on your host server. Storage is provisioned for these
applications.
• Local storage only- Creates a volume on your All-in-One Storage System. Storage is provisioned
for these applications.
2. Click Next to open the Enter an Application Name page (see
“Entering an application name” on page 19).
Entering an application name
Use the Enter an Application Name page to enter a name for the application. This name will be used
anywhere the application is referenced in ASM, so it must be a unique name.
1. Enter a name for the application.
2. When you are done, click Next to open the Storage Allocation page (see
“Allocating space for components” on page 20).
Using the Create a Virtual Library Wizard
This wizard helps you create a virtual library for disk-to-disk backup of other client or servers to your
All-in-One Storage System and manage the storage for the virtual library through ASM. Install Data
Protector Express on additional servers you need to backup. See
“Installing Data Protector Express on other devices” on page 37 for more information.

Hosting storage for applications and shared folders20
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 and local storage applications)
After a logical disk is created, its configuration cannot be changed.
Setting advanced storage properties
Use the Advanced Storage Properties dialog box in the ASM wizards 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 change the allocated space size using the Allocate
Space Wizard. See Increasing or reducing the allocated storage for more information.
Table 4 provides a brief description of the items you can modify:

After 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 and
local storage applications without
an enforced allocated limit. If there
is unused storage space on the
logical disk where a component
without an enforced allocated limit
resides, data can be written to the
component until the logical disk is
full.
You are able to choose SAS, (Serial
Attached SCSI) SATA, (Serial
Advanced Technology Attachment)
or SCSI (Small Computer System
Interface) for a physical disk type,
depending on your hardware.*

A hot spare is a hard drive reserved as a spare
for storage space configured as RAID 1, 1+0,
5, or 6. A hot spare automatically replaces a
hard drive when it fails. When the failed hard
drive is replaced, its replacement becomes the
new hot spare.
The minimum number of physical disks that the
allocated storage will be spread across. Storage
may be provisioned across more disks, but this
setting determines the minimum number of disks
reserved for the allocated storage.
The storage area can be assigned to an existing
logical disk, or it can be assigned a new disk,
which is created upon completion of the
scheduled tasks for the storage wizard.
The number of bytes or kilobytes of data in each
RAID stripe (block of data). The RAID stripe size
selected affects performance. For the best
performance, select the stripe size closest to the

*After you have allocated and configured storage for an application component, user-defined application,
or shared folder using a wizard, you can change the allocated space size, change the percent full warning
threshold, and change the enforced allocated limit (shared folders and local storage applications). However,
you cannot change the RAID level, RAID stripe size, Hot Spares, or Physical Disk Type.
The percent full value that when reached
changes the storage status to Warning and
issues a warning alert. The warning indicates
that storage use has surpassed the percentage
full value. For example, if you enter 75%, you
see a warning (yellow asterisk) in the content
pane when storage is at 75 percent full.
Sets an enforced quota for the amount of storage
available to a shared folder or local storage
application. When the storage space allocated

Hosting storage for applications and shared folders22
Customizing RAID levels
Before you customize the default RAID level setting, review Table 5 to see how the different RAID
levels affect performance, capacity, and data protection level.
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.
• For user-defined applications and shared folders (where industry-standard recommendations cannot
be determined), the wizard provides default settings you can customize.
Table 5 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.
• Data 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 5.
Table 5 Descriptions of RAID levels
No RAID
RAID 0 – Striping (No Fault Tolerance)
RAID 1 – Mirroring
DescriptionRAID level
Offers no protection against disk failure. If a disk drive fails, data is
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 drive 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 because they require 50 percent of the
drive capacity to store the redundant data. RAID 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.
HP StorageWorks All-in-One Storage Manager 23
RAID 1+0 – Mirroring and Striping
RAID 5 – Distributed Data Guarding
DescriptionRAID level
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 1 are the
most costly fault tolerance methods because they require 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, the mirror drive
provides a backup copy of the files 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.
Offers the best combination of data protection and usable capacity
while also improving performance over RAID 6. RAID 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 an 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.
RAID 6– Advanced Data Guarding
(ADG)
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. An iSCSI LUN application will not have a warning threshold.
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 content pane.
• As an alert in the Properties window.
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 has an enabler. Writer
performance is lower than RAID 5 due to parity data updating on
multiple drives. It uses two disk for parity; its fault tolerance allows
two disks to fail simultaneously. Usable capacity is N-2 where N is
the number of physical drives in the logical array.
