   • Difference between Storage Area Network (SAN) and Network Attached Storage (NAS)

     Storage Area Network (SAN) is used for transferring the data between the servers and the storage devices’ fiber channels and switches. In SAN (Storage Area Network), data is identified by disk block. Protocols that are used in SAN are SCSI (Small Computer System Interface), SATA (Serial Advanced Technology Attachment), etc. 

     Components of Storage Area Network (SAN):

     • Node ports
     • Cables
     • Interconnect devices such as Hubs, switches, directors
     • Storage arrays
     • SAN management Software 

      Network Attached Storage (NAS), data is identified by file name as well as byte offset. In-Network Attached Storage, the file system is managed by Head units such as CPU and Memory. In this for backup and recovery, files are used instead of the block-by-block copying technique.

     Components of Network Attached Storage (NAS):

     • Head unit: CPU, Memory
     • Network Interface Card (NIC)
     • Optimized operating system
     • Protocols
     • Storage protocols: ATA (Advanced Technology Attachment), SCSI, FC (Fibre Channel)

     The difference between Storage Area Network (SAN) and Network Attached Storage (NAS) are as follows:

   • Components of Storage Area Network (SAN)

     Components of Storage Area Network (SAN) involves 3 basic components:

     (a). Server (b). Network Infrastructure(c). Storage

     The above elements are classified into following elements like,

     (1). Node port(2). Cables(3). Interconnection Devices(4). Storage Array, and(5). SAN Management Software

     These are explained as following below.

     1. Node port: In fiber channel, devices like,

     • Host
     • Storage

     Nodes consists of ports for transmission between other nodes. Ports operate in Full-duplex data transmission mode with transmit(Tx) and Receive(Rx) link.

     2. Cables: SAN implements optical fiber cabling. Copper cables are used for short distance connectivity and optical cables for long distance connection establishment. There are 2 types of optical cables: Multi-mode fiber and Single-mode fiber are as given below.

     Other than these cables, Standard Connectors (SC) and Lucent Connectors (LC) are commonly used fiber cables with data transmission speed up-to 1 Gbps and 4 Gbps respectively. Small Form-factor Pluggable (SFP) is an optical transceiver used in optical communication with transmission speed up-to 10 Gbps.

     3. Interconnection Devices: The commonly used interconnection devices in SAN are:

     If you're not familiar with the igraph package it is one networking package that works for this type of task rather easily:

     library(igraph)g <- graph.adjacency(df1.adj)plot(g)-

     The first matrix is a Boolean matrix. The conversion you do is an adjacency matrix and the diagonal is the number of times the keywords displayed total. The off diagonals are the link (edges) between two keywords (nodes). These edges could be weighted as well.

     This gives:

     You could also set the diagonal to zero to avoid the edges that are loops:

     diag(df1.adj) <- 0g <- graph.adjacency(df1.adj)plot(g)-

   • Storage Area Networks

     A dedicated, fast network that gives storage devices network access is called a Storage Area Network (SAN). SANs are generally made up of several technologies, topologies, and protocols that are used to connect hosts, switches, storage elements, and storage devices. SANs can cover several locations.

     Data transfer between the server and storage device is the primary goal of SAN. Additionally, it makes data transmission across storage systems possible. Storage area networks are primarily used to connect servers to storage devices including disk-based storage and tape libraries.

     • Fibre Channel (FC): A Fibre Channel is one of the maximum broadly used SAN storage connections. It presents excessive-velocity, low-latency connectivity between servers and storage devices with the use of fibre optic cables. Fibre Channel helps factor-to-factor, arbitrated loop, and switched fabric topologies. It gives excessive throughput, reliability, and scalability, making it suitable for traumatic enterprise environments.

   Why does a raid system need a storage area network (SAN)?

   • Many users of RAID system cannot use the capacity effectively because it has to be attached to a concept called Storage Area Network (SAN). In a SAN, online storage peripherals are configured as nodes on a high-speed network and can be attached and de-attached from servers in a very flexible manner.
