The
SAN - Storage Area Network
A 1-day Introduction
Overview
Today's commercial and industrial environment is based around
large computer storage facilities. Traditionally these have
been 'Just a Bunch of Discs' (JBOD) but, with high-growth
in data volumes coupled with requirements for absolute reliability
and rapid access, scalability of the traditional techniques
and their costs have become problems. Managing expensive storage
resources in large, rapidly growing, mission-vital data centers
can be both daunting and expensive. SANs provide a route to
significant technical advantage coupled with reduced costs
and complexity.
This one-day course is intended to cover the whole subject
of Storage Area Networks (SANS), both the commercial drivers
as well as the technology. The evolution of architectures
and their relative advantages and disadvantages are examined
and the range of SAN components are identified. Some technologies,
especially those specific to SANs, such as Fibre Channel are
examined.
