Capacity on Demand
Scalar i2000 Planning Guide 28
Capacity on Demand
If you purchased capacity on demand, the library is initially licensed for a
default configuration of 100 SDLT or 102 LTO storage slots. The number
of storage slots differs between media types because the library only
supports full magazines for capacity on demand.
The library’s license key must be enabled during installation to configure
those parts of the library that are governed by additional licensing.
Customer license keys are available from Quantum Technical Assistance
Center (ATAC).
The capacity on demand library can be expanded from a single module to
up to eight modules. With capacity on demand, you can purchase enough
storage to accommodate your current needs. As your storage needs
change you can add storage in blocks of 100 cartridges, without being
required to purchase additional hardware. Capacity on demand begins at
100 cartridges and can be increased to as many as 3,492 LTO or 2,915
SDLT cartridges inside one library.

Encryption and Quantum’s Encryption Key Manager
The default setting for IBM LTO-4 encryption-capable drives permits
external application-managed encryption support on all encryption-
capable tape drives and media within a partition.
Optionally, you can purchase the Quantum Encryption Key Manager (Q-
EKM). Q-EKM is a licensed Java software program that generates,
protects, stores, and manages the encryption keys. These keys are used to
encrypt the information being written to tape media and read from tape
media. Policy control and keys pass through the library-to-drive
interface; therefore encryption is transparent.
Q-EKM was designed to
generate and communicate encryption keys for IBM LTO-4 FC drives in
Quantum libraries across the customer’s environment.
