Storage Area Networks (SAN's)
A Storage Area Network (SAN) is, in its simplest terms, a network dedicated to the storage of data.
Network storage is moved from its traditional location (inside / directory connected to file servers)
to a separate network of its own and connectivity is achieved independently of the LAN using a fibre channel.
A single Storage Area Network (SAN) can continuously provide storage for multiple servers running different
operating systems (i.e. Windows, NT4, 2000, Linux). SAN storage is accessible from the servers, so users can
access any storage device on the Storage Area Network (SAN), regardless of the physical location of the storage
or the users.
This flexibility enables a Storage Area Network (SAN) infrastructure to be implemented, without radically
changing the existing IT environment.

Storage Area Networks (SAN's) offer many benefits over traditional storage devices:
- Online scalability - add storage elements as and when required
- High levels of availability - to both data and applications, even during back ups / restoration
- Simple and centralised management – reducing IT administrator time and the number of administrators required
- Faster data back up and restoration - businesses recover in minutes not hours
- High utilisation of disk capacity - multiple servers share storage space for maximum efficiency
- New levels of resilience for stored data, increasing availability for continuous access
- Supports storage on a scale that can't be achieved with Direct Attached Storage (DAS)
- High data transfer speed over a fibre channel infrastructure.
The cost of Storage Area Networks (SAN’s) continue to decrease dramatically and consequently,
SAN’s are no longer just a storage solution for large companies with huge IT budgets.
Storage Area Networks (SAN) are now a viable solution for most companies whose data storage requirements
cannot be met by their current infrastructure. At basic, we take a highly consultative approach and work closely
with our clients to assess their current IT infrastructure and future data storage and protection requirements,
before proposing the optimum storage solution. .
