LRM - THE LIBRARY
RESOURCE MODULE
The LRM is a
complete library unit containing control electronics, tape drives,
storage slots, I/O ports and our unique robotic media handler. Each LRM
is highly scalable making it easy to vary drive and cartridge slot
ratios to fit your needs. |
MEM - THE MEMORY
EXPANSION MODULE
When your
storage needs grow beyond an LRM, one or two MEMs can easily be added.
Using Qualstar’s trademark rotating carousel cartridge storage design,
each MEM contains 1,075 additional slots in a very dense, compact
footprint. |
An LRM holds any mix of up to 20 or 32 Fibre Channel or SCSI LTO drives
depending on the model. Bays holding up to 4 tape drives or 30 media
storage slots can be mixed and matched to meet changing requirements. Up
to 40 I/O slots are supported in each LRM.
