San Storage Area Network Lun

In computer storage a logical unit number or lun is a number used to identify a logical unit which is a device addressed by the scsi protocol or storage area network protocols which encapsulate scsi such as fibre channel or iscsi.

San storage area network lun.

A san storage platform presents pools of raw data to a server infrastructure. Luns are key to disk array configuration because disks are typically defined in sets of raid groups to protect against failure. The storage area network san fabric must also be configured so that drive arrays and luns are managed and security on the san is achieved by ensuring only those servers that have authorisation. In a san fabric lun storage is essential to the configuration of the environment and its performance a lun is a unique identifier given to separate devices or logical units so they can be accessed by a scsi iscsi or fibre channel protocol.

A storage area network san or storage network is a computer network which provides access to consolidated block level data storage sans are primarily used to access storage devices such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct attached storage a san typically is a dedicated network of storage devices not accessible through. A lun may be used with any device which supports read write operations such as a tape drive but is most often used to refer to a logical disk as created on a. A storage area network san is a centrally managed high speed storage network consisting of one or more vendor storage systems storage management software application servers and network hardware that allows users to access and utilize business information data.
