A contrasting option to utilizing DAS
is to independent storage from your servers and put it all alone particular,
elite storage network called a storage area network (SAN). With a SAN,
storage is no more oppressed to a solitary server yet sits freely on the SAN
where it can be shared, cut, diced, and designated to servers, clients and
applications from a solitary pool.
For quite a long time, SANs kept
running on a mind boggling innovation called Fiber Channel that was excessively
costly and complex for all except the most performance hungry little businesses.
However a genuinely new SAN innovation called iSCSI offers great execution,
utilizes the same hardware as your Ethernet network, and is generally easy to
utilize.
Like DAS, in any case, SAN storage
utilizes a low-level, block based storage design that requires a
server with a working framework to present records to clients. Every server
needs its own particular iSCSI host connector or initiator programming to speak
with the SAN. That is the reason in case you're for the most part hoping to
share records and printers; an undeniable SAN can be needless excess. SANs are
most proper on the off chance that you require elite for databases, server
based business applications, and email.
