Advanced Digital Information Corporation (ADIC) has updated its Pathlight VX disk backup solution to offer more performance and
scalability for less.
ADIC claims that Pathlight VX 2.0 is the first open system backup product to
combine the capacity and characteristics of disk and tape in a single,
unified system, using policy-based data management technology to provide
total system capacity of almost 3,000 terabytes.
The combined system fits
into existing backup environments, presenting itself to applications as a
virtual tape library that transparently includes disk elements for high
performance and RAID fault tolerance and tape elements for low-cost capacity
and disaster recovery.
“ADIC is advancing disk backup into an important new phase by combining the
characteristics of disk and tape in an integrated system,” Dianne
McAdam, senior analyst and partner at Data Mobility Group, said. “Disk has great
attributes for some parts of backup, but tape is a requirement, too, not only
for compliance with retention regulations, but simply for economical scale.
In standard enterprise capacity ranges, the cost of tape storage will remain
several times lower than disk for the foreseeable future. ADIC’s approach
toward combining the two technologies gives users the best characteristics
ADIC says Pathlight VX 2.0’s approach lets customers backup and restore
critical data at twice the speed of conventional backup systems.
Policy-based management enables what the company claims is another first:
automated life cycle management for backup data, including the ability to
create multiple copies on different media types.
Pathlight VX 2.0 provides throughput up to 2 TB/hour. Disk storage elements
range from 3.8 to 46.8 TB capacity. Tape storage is provided by integrating
ADIC Scalar and StorageTek L-Series libraries. Single-library configurations
can reach 2,823 TB native capacity — 5,599 TB with normal compression.
For compliance with long-term data retention and disaster recovery
requirements, Pathlight responds to backup software commands by exporting
application-readable media that can be restored in any standard tape drive
Data management policies in the 2.0 release include the capability to retain
key data on disk for faster recovery of historical information, automated
creation of up to four copies of data for redundant protection, and
retention of local copies of data after a copy has been exported.
ADIC corporate marketing manager Steve Whitner says costs for Pathlight VX 2.0
range from $15 a gigabyte for a 45 TB solution, depending on the disk and
tape configuration, to as low as $2 a gigabyte for a very large solution.
A 43.8 TB solution that includes 3.8 TB of disk and a Scalar 1200 library
would cost $261,583, or about $6 a gigabyte, including media and two years
of onsite service.
Pathlight VX 2.0 will be available January 2005.
