Storage Management Infrastructure; Managing Storage For Application Servers - HP STORAGEWORKS ALL-IN-ONE STORAGE SYSTEM User Manual

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.

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:
• Managing storage for application
• Managing storage for shared

Managing storage for application servers

With ASM, you can allocate, configure, and host storage for applications residing on servers that
host Exchange, SQL Server, and user-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 fit your storage
needs. However, the default advanced settings provided for Exchange and SQL Server are based on
HP storage, Exchange, and SQL Server best practices and should generally not be changed.
For application storage, ASM creates an iSCSI LUN on your HP All-in-One Storage System for each
storage 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 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 automatically saved to your HP All-in-One Storage System instead (see
Figure 14).
