AMASS Overview
1-16 Online Archiving with AMASS 6-00026-01 Rev A
Scattered writes allows AMASS to use more than one drive to
write to volumes in a volume group. For configuration
parameters, refer to Installing AMASS.
Compression and
Block Size Improves
Throughput
Configuring compression and block size typically improves
throughput for tape drives. Both features are configured with
the AMASS volformat command. For more information on
this command, refer to Managing the AMASS File System.
Refer to the AMASS Release Notes for a list of drives that
support compression and configurable block size.
Library
Drive1
Drive2
Enabling scattered writes allows AMASS to
use more than one drive to write data to the
same volume group. Consequently,
performance is improved.
Volume Group 6
Drive1 writes file_A to media.
Drive2 writes file_B to media.
