Virtual Storage Manager (VSM) system |
| The
StorageTek® Virtual Storage Manager® (VSM®) system
allows you to use the entire capacity of your tape
cartridges and achieve 100 percent tape automation.
Instead of wasting up to 60 or 70 percent of mainframe
tape storage space, you can now use 100 percent of the
capacity you pay for and realize savings in resources,
space, time and money. |

Applications |
Archiving
and offline processing
VSM combined with fast-access T9840 tape drives and
high capacity T9940 tape drives provides customized
archiving or batch processing storage that shortens
response times for active data while reducing
long-term storage costs. |
Disaster
recovery
When implemented as part of a remote vaulting
infrastructure, VSM makes disaster recovery more
efficient by reducing data volume and the number of
tapes to manage. High data transfer rates further
speed recovery. |
Backup
and restore
VSM eases the challenges of backup and restore in
large mainframe environments by consolidating and
accelerating backups. Tape utilization and data
access are increased. Backup windows are shortened
by as much as 50 percent. |
|
| |
|
Benefits |
Decreased
costs
The VSM system helps you maximize the efficiency of
your data center, decrease environmental and
management costs, and unleash the profits trapped in
underutilized assets. |
Enhanced
data protection
Flexible data movement capabilities and policy-based
management features enable you to customize your
backup and disaster recovery processes to better
protect your data. |
Increased
productivity
With the VSM system, you can access data at disk
speeds, automatically migrate data, simplify storage
management, recoup IT hours and reallocate empty
libraries. |
Higher
resource utilization
The ability to use 100 percent of the space on your
tape cartridges enables you to expand your usable
library capacity, enhance performance and reduce
your use of floor space. |
|
| |
|
Features |
A
complete solution
The VSM system works with StorageTek libraries, tape
drives and software to provide a complete virtual
tape solution. |
Advanced
management
The VSM system provides sophisticated policy
management capabilities and a centralized point of
control. It enables you to exploit mixed media and
recording technologies and to customize policies for
individual workloads. |
Virtual
tape drives
Each system emulates up to 256 tape drives.
Virtualization enables you to reduce your use of
real tape drives and media, support peak demands
with less equipment and reduce physical cartridge
mounts. |
