with the host and virtual tape environments are set up correctly.
Capacity planners love to
focus in on Tape Volume Cache
(TVC) rated in hourly utilization
in gigabytes. An average of active
gigabytes rated against the maximum of TVC size and an 85 percent maximum threshold shows a
good picture of virtual tape performance in the environment.
Another important consideration of virtual tape metrics lies in
the area of recovery point objective (RPO). RPO is the maximum
targeted time period in which data
might be lost from an IT service
due to major issues with production. Shops often strive to hit zero
RPO on virtual tape for perfect
business continuity, and the ability
to utilize virtual tape is spot on
when it comes to this objective.
The impact of virtual tape on
RPO can be amazing. Data from
virtual tape storage can be electronically moved over a network to
another site, just like with DASD. A
variety of reporting mechanisms
show exactly how much data is
located at off-site locations.

An Applied Use
of Virtual Tape Storage
The manufacturing and banking
industries have been heavy users
of virtual tape in the past, and that
still rings true today. Virtual tape
storage performance capabilities
match up well with disk technologies and have a true 4:1 compression capability, making it a solid
solution to consider.
One large manufacturer (bit.
ly/2MopDeN), for example, was
facing the problem of a soon-to-be
unsupported tape infrastructure,
Ä Èî0 Ã&%Ã%%'ÉÃ"$!(ÉÈÃ&!ÃÆÉÃÄÃ
challenge. The company was very
much committed to mainframes
but it needed relief to better its
OPEX versus CAPEX approach.
Enter the virtual tape system.
After completing a modernization

study for tape that reviewed its
current tape environment, a proposition was pursued to replace the
company's current tape infrastructure with virtual tape storage.

Walking the Path
of Virtual Tape
One of the biggest advantages of
virtual tape over real tape is that it
can bring a quick ROI, which is a
good thing when it comes to managing your data center expenses. If you
haven't already done so, you should
take a look at an open storage-based
virtual tape system as it can provide
cost savings, the ability to scale and
increased reliability.
Because virtual tape is really a disk technology, data can
be electronically transferred,
boding well for DR applications.
The software-only virtual tape
systems are the least expensive.
Performance, when compared
to real tape, is better, especially
when you consider the elimination of rewind and mount times by
the operation staff.
Virtual tape takes on a tried and
tested storage methodology, making it better without losing the original format. The original format is
tape, but with virtual tape systems,
it's now in a disk format. You owe it
to yourself to better understand the
path that virtual tape can provide
in your data center.

Tape Backup
Is Shifting Gears
With Virtual Tape
Libraries
For many years, backing up to
tape drives and libraries has presented many unique challenges.
These typically include poor
performance; lack of redundancy
and reliability; on- and off-site
media rotation management
headaches; security concerns with
lost media, and the high costs of
tape consumption and extended
maintenance. Whether you're looking to solve those problems with or
without your existing tape drives,
virtual tape libraries can help.
Without any noticeable learning
curve and while maintaining complete compatibility with all existing
tape drive operations, a properly
engineered virtual tape library will
provide better backup and restore
performance; redundantly scale as
your backup requirements change
over time; completely automate
on-site and off-site copies/replication; and lower the amount of time
and money spent on administering
and protecting your valuable data.
In addition, they can secure
your local and remote backups
from unauthorized access and
allow you to remotely control and
inventory all off-site copies. Adding
a virtual tape library as part of your
backup strategy will yield many
