Interface Manager and Command View for Tape Libraries Software user guide 73 74 Command line interface 4 Advanced features The Interface Manager card supports optional features that can be licensed separately: · HP StorageWorks Direct Backup Engine--This feature provides a direct or serverless backup solution that streams data directly from an HP disk array to a tape drive in a supported library without sending data through an application server. The Interface Manager card is required to activate this feature. · HP StorageWorks Secure Manager--This feature has two main functions: · Host Access--Gives the library administrator control over which libraries or drives within a library may be accessed by the various backup hosts on the SAN. · Library Partitioning--(Advanced Secure Manager only) Enables the library administrator to divide the physical library into multiple, logical libraries. · HP StorageWorks Licensed Capacity Panel Upgrade for ESL E-Series--With certain tape libraries, additional capacity can be licensed as needed. The Licensed Capacity Panel Upgrade for ESL E-Series feature enables you to enter a license key to unlock this additional capacity. Other functionality described in this chapter includes: · Obtaining and installing license keys · Using support tickets Direct Backup Engine HP StorageWorks Direct Backup Engine provides a direct or serverless backup solution that streams data directly from an HP-supported disk array to a tape drive in a supported tape library without sending the data through the application server. This greatly improves performance and eliminates the need for backup servers to keep up with increasingly powerful tape drives. Direct Backup is available for some ESL9000 and ESL E-Series models. Refer to product QuickSpecs and the HP Enterprise Backup Solutions matrix for information on availability and compatibility. With the traditional backup method, the backup host server requests the data from the disk array and then resends the data back out to the appropriate tape drive in the library. With Direct Backup, the backup application on the backup host server sends a command directly to a FC interface controller in the tape library. The FC interface controller then requests data directly from the disk array and sends that data directly to the appropriate tape drive. This process is repeated until the backup job is complete. Interface Manager and Command View for Tape Libraries Software user guide 75 Requirements The following requirements must be met to use Direct Backup: · HP StorageWorks ESL9000 or ESL E-Series tape library, operating in a SAN environment, with the following hardware installed: · Interface Manager card · Up to four (with ESL9000 Series) or six (with ESL E-Series) of any of the following HP StorageWorks interface controllers: · e2400 · e2400-FC 2G or 4G · e2400-160 FC · Backup application software that supports serverless backup · HP disk array · One or more valid Direct Backup license keys must be installed for each library using Command View TL. Each tape drive that will use Direct Backup must be covered by the LTU (license to use) quantity for each license key. For example, if you have two license keys and one license key has an LTU quantity of four and the other has an LTU quantity of two, a total of six drives can use Direct Backup. See Obtaining and installing license keys for more information. Using Direct Backup Before using Direct Backup, you must obtain and install the license key. See Obtaining and installing license keys for more information. Configuring the SAN to work with serverless backup is beyond the scope of this documentation. Many of the SAN requirements depend on the backup application used. For instructions on how to set up and use serverless backup, see your backup application documentation. Enabling Direct Backup on tape drives Before you can use Direct Backup, you must first indicate which drives will use the feature. The number of drives that can use Direct Backup is determined by the LTU quantity of the license key or keys enabling Direct Backup.
