Year there is the best way to get the type of network storage, some are discussed. It depends on the same computer and the decision of the majority of your environment. The NAS and SAN are the main differences between the NAS Network

Attached Storage
NAS file system, located between the application servers is defined products. In the box, the network acts like a hard disk, hard disk and in reality, the network ports that are in advance is the computer that is configured to act as file servers.
The user, like a file on the remote computer may be used on the local hard drive.
Is, LAN machines can connect to most (to the LAN or via WAN), NAS to connect to file shares and NFS, CIFS or HTTP can be used are connected to each other protocol. NAS, a low-cost solution to slow network and the extra bandwidth needed for that I / O The SAN File System and is located between the underlying physical storage of your architecture is defined.

Network requirements of particular standard or existing applications, for example, bandwidth can not handle the installation as usual. This is to share disk space among multiple computers enabled more using server clusters to improve performance.

Only server class devices with SCSI Fiber Channel, SAN, you can connect to. , Fiber Channel, SAN up to about 10 in the state are limited to km.

Details of the SAN are much faster, but it is expensive and requires more maintenance. Each host system, or SAN switch SAN may direct a special card to be connected to some sort of.

The type of support network
NAS of TCP / IP network uses: Ethernet, FDDI, ATM (probably TCP / IP and one day through a fiber channel)
Fiber Channel SAN and use the
Protocol
NAS of the TCP / IP and use the NFS / CIFS to / HTTP to
Use the encapsulation of SCSI SAN
NAS for these types of applications:
File services
File Sharing
The user's home directory
Content Archive
Metadata directory
E-mail repositories, such as PST files Companies
Grid computing (), using 10 Gigabit Ethernet
Peer-to-peer data sharing
SAN is ideal for these types of applications:
Database
Server clustering
Backup
Data Replication
Grid computing
Data Warehouse
Recovery Archive
Move data, applications that require high bandwidth and low delay.
