| Q1. |
What is the benefit of this architecture? |
| A1. |
The Extended Tape Library Architecture (ETLA) is aimed at providing reliability for tape library backups in enterprise SAN environments. ETLA does this by providing advanced features and capability to deliver secure managed access, intelligently handle network events and conflicts, as well as detect and track SAN-specific errors. |
|
| Q2. |
Does the controller introduce a single-point-of-failure? |
| A2. |
Solution-level reliability is measured by the ability to successfully complete backup and restore operations and the availability of the storage. This is primarily affected by configuration issues, changes in the SAN, storage network events or collisions, interoperability issues, and storage network failures – not hardware failures. The architecture is designed to address these issues as well as provide the ability to identify and resolve problems quickly which improves system availability. HP controls both manufacturing and firmware development of its interface controllers to ensure maximum quality and reliability. |
|
| Q3. |
Is the architecture expensive? |
| A3. |
Connecting tape drives to the SAN requires hardware to aggregate multiple tape drives per Fibre Channel (FC) link in order to be cost-effective. For native-FC tape drive libraries, this would typically mean additional switches. By providing aggregation, controllers can recover much of the incremental cost difference over a non-controller alternative. The HP StorageWorks Extended Tape Library Architecture also provides reduced administration effort that reduces total cost of ownership as well as offering advanced functionality that provides better value and ROI. |
