Difference between SAN and NAS

SAN and NAS are both network-based storage solutions. A SAN typically uses fiber channel connectivity, while the NAS typically ties into  the network through a standard ethernet connection. So here this article gives the information about the difference between SAN and NAS to better understand this topic.

Whst is NAS?

NAS stands for network attached storage. The data is identified by the file name as well as byte offset. In NAS, file system is managed by a head unit such as CPU and memory. 

What is SAN?

SAN stands for storage area network, it used for tranferring the data between the servers and the storage devices fiber channel and switches. SAN, data is identified by disk block. Protocol that are used in SAN is SCSI and SATA etc.

Difference between NAS and SAN:

  • It is file-level data in NAS, while the SAN is block-level data.
  • NAS is ethernet media, while the SAN is a fiber channel.
  • NAS is an I/O protocol, while the SAN is a SCSI protocol.
  • NAS appears to OS as a shared folder, SAN appears to OS as attached storage.
  • NAS is inexpensive, while the SAN is too much expensive.
  • In a NAS system, the data accessed as if it were a network-attached drive, while the SAN servers access data as if it were a local hard drive
  • NAS is dependent on the LAN, while the SAN is independent of the LAN.
  • NAS requires no architectural changes, while the SAN is required architectural changes.
  • NAS used in homes and small to medium-sized businesses, while the SAN often used professional and enterprise environments.
  • NAS is easier to manage, while the SAN is required more administration.
  • NAS uses SMB/CIFS, NFS, SFTP, and WebDAV, while the SAN uses fiber channel, ISCSI, And FCoE.
  • NAS is simply connected to your existing ethernet network, while the SAN requires a dedicated fiber channel connection for clients, servers, and storage and often a separate dedicated ethernet network for file request traffic.
  • NAS the entry-level system often have a single point of failure, while the fault-tolerant in SAN network and system with redundant functionality.
  • NAS is a central place from which to back up or sync user files, while the SAN a place from which to archive files not immediately needed.

Advantages and Disadvantages of SAN

SAN stands for storage area network, it is a dedicated high-speed network particularly used for data storage. This network is built with servers, fiber optics, and storage devices. In this system, the storage device is not directly connected to the servers. So here this article gives the advantages and disadvantages of storage area networks to better understand this topic.

Advantages of Storage area network:

  • Simplified storage administration
  • Disk mirroring
  • Low cost of storage management
  • Instant and real-time information
  • Ability to boot itself and expand the storage capacity
  • Hundreds of terabytes of data can be stored using any number of storage devices.
  • SAN is not directly attached to any particular server or network, SAN can be shared by all

Disadvantages of storage area network:

  • If client computers need intensive data transfer then SAN is not the right choice. SAN is good for low data traffic
  • More expensive
  • It is very hard to maintain
  • As all client computers share the same set of storage devices so sensitive data can be leaked. It is preferable not to store confidential information on this network.
  • Poor implementation results in a performance bottleneck
  • It's difficult to keep a data backup in case of a system failure.
  • Not affordable for small business
  • Require a high-level technical person

Advantages and disadvantages of IPV4

The Internet Protocol Version 4 (IPV4) is the first version of the protocol (IP). In 1983, it was made available for development on the ARPANET. It is currently the most commonly used IP version. It is used in conjunction with an addressing scheme to classify devices on a network. IPV4 is the 32-bit address scheme which is allowing to storage of 2^32 addresses which is more than 4 billion addresses. So here this article gives the advantages and disadvantages of IPV4 to better understand this topic.

Advantages of IPV4:

  • IPV4 is necessary to encrypt data to ensure privacy. It takes security measures to encrypt data in its address packets.
  • IPV6 protocol can be easily supported by most of the topology drawings. 
  • Since addresses are combined more effectively the process of routing has become more efficient in IPV4.
  • Both devices can easily handle IPV4 routing, which is part of the IPV4 protocol. As a consequence, practically every major device will accept the IPV4 protocol.
  •  IPV4 does to great lengths to ensure that data packets arrive at their destination. This is because the transmission control protocol employs IPV4 variants.
  • IPV4's main aim is to connect various types of devices to one another.

Disadvantages of IPV4:

  • By defining the use of the internet, IPsec provides network protection to IPV4. However, the issue arises when IPSec is not built-in and its use is optional.
  • IPV4 needs either manual or automatic configuration. DHCP is difficult because its infrastructure needs different management.
  • Despite the fact that IPV4 has a mobility specification, it is considered inefficient. This is due to the fact that it operates on its own infrastructure. Its mobility nodes are also unsuccessful.
  • Individual IPV4 address prefixes are allocated to each router so that it can operate independently. Today's Internet uses both flat and hierarchical routers. On the internet, there are over 85000 roads.
