ADIC 6-00028-01 Rev A Disparate Media in the Space Pool

Managing the AMASS File System

Likewise, the cleaning group must contain volumes with uniform, drive-specific attributes. For cleaning volume groups, see “Create a Cleaning Volume Group” on page 1-20.

Disparate Media in the Space Pool

The space pool can contain volumes with a variety of formats. Therefore, if a site uses both WORM and erasable optical platters, AMASS always has a selection of media from which to pick.

For example, if volume group 47 runs out of space, AMASS automatically takes a volume from the space pool with the appropriate attributes and reassigns it to the out-of-space volume group. Thus, AMASS continues to write data to volume group 47 and performance does not suffer.

Using Numeric Volume Groups

You can archive a specific directory by using numeric volume groups. This concept is shown in the following illustration:

Library

AMASS

/archive

Volume Group 2

/sales /pubs

~ ~

AMASS archives /pubs files to volume group 2.
