Two new competing tape technologies have been introduced recently,
LTO 2 and SDLT 320. Both products
represent evolution from a previous
generation rather than complete new
products. In many ways this is preferable
as it ensures compatibility with a
large range of existing tape libraries
and provides backward read compatibility
with the previous generation of product.
Both factors offer continued investment
protection for the majority of users.
DLT tape has been the dominating tape standard for enterprise use
for many years. There are thousands
of companies arround the world that
rely on this well proven technology
to protect thier data. SDLT 320 uses
the same Super DLTtape I cartridges
as the SDLT 220 and is backward read
compatible with DLTtape IV media,
preserving investments in previous
DLT technologies. For this reason
alone DLT will continue to be a dominant
player in the tape market.
LTO Ultrium formats are open standards. This means that data written
on any HP StorageWorks Ultrium 460
Tape Drive should be directly interchangeable
with Ultrium 2 tape drives from Seagate
and IBM. As our Companies name suggests,
we strongly endorse the use of open
standards. LTO delivers on the promises
of cost effective product with three
manufacturers producing competing
tape drives to the LTO specification.
In
our comparison table below we have
used the HP Ultrium LTO2 product specs.
The HP drive incorporates an Adaptive
Tape Speed which dynamically matches
the transfer rates of slower hosts
(from 10 MB/s upwards), which increases
performance, reduces mechanical wear
on the drive and extends tape life.
The
latest AIT generation, AIT-3, is included
to round out the comparison of recently
released tape offerings. Your Open
Storage Solutions representative will
be pleased to tell you more about
these technologies and recommend a
tape library that supports these drives.
Please use our tape configurator link
at the bottom of this page to receive
more information.
