Network Attached Storage (NAS) solutions

NAS is a storage networking architecture that allows storage subsystems to connect directly onto the existing computing network, the Local Area Network (LAN). Traditional storage subsystems apply Direct Attached Storage (DAS) to the back end of the servers and have used costly application server capacity to transfer data from storage devices to clients. This “application server tax” is avoided in the NAS architecture by attaching a smaller, less expensive server to a disk subsystem and directly attaching the combined subsystem onto the LAN, thus forgoing the traditional dependence of file system access on the application servers.

Benefits of NAS Architecture

A NAS architecture lowers storage management costs by simplifying the storage process and achieving heterogeneous connectivity, Thereby enabling file sharing across multiple platforms which allows storage to be centrally managed.

Reliability, Availability, and Serviceability
NAS can be implemented over existing TCP/IP networks
Clients can directly access data over LAN without going through a server, freeing server capacity for other tasks and thus improving network performance
Manageability, simplified data management and heterogeneous connectivity between multiple platforms (Unix & NT versions).
Performance, NAS appliance is running a thinner operating system than a general-purpose server, it can deliver similar or higher performance with less computing power.
Low Total Cost of Ownership (TCO), quick and easy installation which saves on IT staff costs.

Storage Area Network (SAN) solutions

SAN is a storage networking architecture that enables the more efficient use of storage assets by decoupling server and storage capacities with a dedicated network. Much like a Local Area Network (LAN), a SAN enables greater scalability and reliability for computer storage resources, making them less expensive to implement and easier to manage. In a SAN, a dedicated storage network is inserted between servers and various storage subsystems. The storage network is generally composed of a number of switches which interconnect servers and storage.

Benefits of SAN Architecture

The SAN architecture offloads the bandwidth used by data transfers between storage systems from the LAN and servers.

Reduces overall cost of storage management
High availability
Any-to-any connectivity
Frees server capacity
Reduces LAN congestion
Storage not dedicated to one server
Increases data transfer rates
Enables serverless & LANless backup
Heterogeneous connectivity UNIX & NT version
File sharing
