Library Features
Density
The library provides a storage density of 758 cartridges (LTO) per square meter. Each module, also
referred to as a frame, has two storage racks: one on the drive side and another on the door side.
A rack consists of up to 10 horizontal sections and three or four columns of magazines, depending
on the rack configuration. Each magazine, located at the intersection of a particular section and a
particular column, consists of six cartridge slots.
Centralized Management
The Library Management Console (LMC) gives you a single point from which to view all library
components, including robotics, drives, storage, I/E stations, and network connectivity. You can use
this graphical user interface both locally from the library OCP and remotely from a remote client. The
LMC communicates with the LMC server that runs on the library. The LMC uses a simple and intuitive
graphical style that is secure and provides library managers with native partitioning ability.
Proactive Availability
The library can alert you about problems before they occur. The library checks the complete data
path at user-defined intervals to make sure that it is functioning properly before backups begin. The
library also monitors its six major subsystems (drives, power, robotics, cooling, connectivity, and
control). You can configure the library to send notifications of problems to one or more e-mail accounts,
including HP service personnel. For more information about the library monitoring and reporting
capabilities,
Chapter 5 .
Serviceability and Reliability
The library has extensive serviceability and reliability features. You can hot swap drives, power
supplies (in redundant power configurations only), and fans.
Your backup system and data path are idle most of the time. When backups begin, the system is used
intensively at maximum bandwidth. The library provides you with notifications and a robust event
system that notifies you of any problems it identifies, enabling you to solve them before backups begin.
For more information about the library notification system, event system, and other troubleshooting
help, see
