Network Attached Storage(NAS) :<\/strong><\/p>\r\n\r\n\r\n\r\n

The NAS stands for Network Attached Storage. NAS appliances work as pure file servers which controlled by their own integrated network operating system. The memory organized through file sharing, meaning that access to data is only possible at the file system level.<\/p>\r\n\r\n\r\n\r\n

Storage Area Networks(SAN) :<\/strong><\/p>\r\n\r\n\r\n\r\n

SAN stands for \u00a0Storage Area Network. It also includes iSCSI. SAN is the technology which sometimes is also referred to as IPSAN or Storage over IP for storage networks, dictates the operation of direct storage protocols natively via IP. \u00a0It works by encapsulating SCSI data into TCP\/IP packets and transporting them via IP networks. Then the SCSI router transports the encapsulated SCSI commands to the corresponding target system based on existing mapping tables. This way, without setting up separate storage devices, iSCSI allows access to the storage network via a virtual end-to-end connection.<\/p>\r\n\r\n\r\n\r\n

Topology Of SAN And NAS :<\/span><\/span><\/strong><\/h2>\r\n\r\n\r\n\r\n

Some important Features Of NAS:<\/strong><\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. Those PC that can connect with LAN (interconnected to the LAN through a WAN) permit NFS, CIFS, or HTTP protocol to connect to a NAS and share files.<\/li>\r\n
  2. NAS recognizes the data with the help of file name and byte balance, moves file meta-data, and also manages security, user verification, and file locking.<\/li>\r\n
  3. NAS specifically permits information sharing between Unix and NT.<\/li>\r\n
  4. NAS head unit manages the file system.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Some important Features of SAN :<\/strong><\/p>\r\n\r\n\r\n\r\n

      \r\n
    1. Only when server class devices with SCSI Fibre Channel can connect to the SAN.<\/li>\r\n
    2. A SAN addresses data by disk block number and transfers raw disk blocks.<\/li>\r\n
    3. In the case of SAN file sharing process is depends on OS.<\/li>\r\n
    4. In the case of SAN File System is handled by servers.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n\r\n\r\n\r\n","protected":false},"excerpt":{"rendered":"
