The Sun in Baltimore put the wraps
on a storage equipment upgrade that has breathed new life into its storage area
network project.
The newspaper purchased an L180
digital tape library from Storage Technology Corp. in December 2002 as part of
its effort to increase its storage capacity to 5.5 terabytes, enough room to
store trillions of words and millions of images.
The Sun began installing the
library April 11 and completed the project in mid-May.

It more than quadrupled The Suns
previous tape library storage capacity, said Dennis Downing, network analyst at
The Sun.
The reason for upgrade was that
the previous (tape device) could not be part of an enterprise storage (system)
capable of moving data back and forth at sufficient speeds, said Downing. In
doing the research and homework, our data showed us that (the L180) had the
(capacity and data throughput) that is capable of doing what we needed to do.
The newspaper (Monday-Tuesday,
236,506; Wednesday-Saturday, 304,244; Sunday, 470,014) already manages more than
2TB of data. Downing said The Sun adds another 1TB of data each year.
The tape library features drives
that can store data at rates of up to 2 gigabits per second through specialized
Fibre Channel interfaces. The interfaces allow The Sun to link the library to
its storage area network, or SAN, an architecture that allows myriad devices to
transfer data through a high-speed network.
Downing said 24 departments and 11
remote locations funnel data to the tape library.
Data is divided into two
categories: production and management information, Downing said. While the
majority of data is now management information, workflow data is increasing.
The librarys speed enables users
to access long-term records much more quickly, Downing said, citing as an
example classified ad reps who may need to get to that data in a short period
of time because it will have to be done while they are on the telephone.
The L180 tape library is part of
the newspaper's SAN, which includes five LTO Fibre drives connected to dual
Brocade Silkworm switches.
Data is transferred via The Suns
existing network and managed by a switch, manufactured by Nishan Systems, that
permits storage data to flow through the same network as live production
information. Storage management is provided by an application developed by
Veritas Corp.
Downing said the addition of the
tape library is part of a continuous strategy by The Sun to maintain enough
storage capacity to support its operations.
There are other phases that we
will add to it, he said. We will add (data) directors, well add
additional switches and consolidate servers into the network.
