The directed-attached storage marketplace has been about since the starting of servers. As a outcome of these broadly accepted requirements for network data access, storage devices that serve information straight more than a network (called Network Attached Storage or NAS devices) are far much easier to connect and handle than DAS devices.

As an alternative of placing the storage directly on the network, the emerging SAN idea puts a network in in between the storage subsystems and the server as (Figure three). This means that SAN really adds network latency to the DAS storage model. This trend benefits the systems vendors that have a robust affiliation with compute infrastructure and DAS, but hurts classic ‘storage only’ vendors who have made their bread and butter on shared storage infrastructure. What I imply to say, is that other computer systems access SAN and NAS devices differently. When it comes to speed, networks … Read More
