Shared Digital Storage
Why Shared Storage?
The Short Answer:
To Save Time and Money and, thus, Make Money!
The Long Answer:
For many years, digital storage has been directly attached to, or embedded
in, workstations (computers). Direct-attach storage works fine if you
work completely alone, don't care much about storage efficiency, and
don't need to share your data. On the other hand, if you work in a team/workgroup
(as most of us do!), want to save storage dollars (as most of us do!),
or need to share data (as most of us do!), direct-attach storage forces
you to physically "swap" storage devices ("sneakernet"),
acquire excess storage, or slowly "stream" high bandwidth
data between workstations. These "old crutches" are extremely
inefficient from a workflow perspective, costly
from a storage perspective, and highly dangerous from a data integrity
one. The solution (cure!): A centralized pool of high-speed, shared
(networked) storage - - the Fibre Channel Storage Area Network (SAN).
