SAN zoning is a method of arranging Fibre Channel devices into logical groups over the physical configuration of the fabric. SAN zoning may be utilized to implement compartmentalization of data for security purposes. Each device in a SAN may be placed into multiple zones. Hard and Soft Zoning Hard zoning is zoning which is implemented …
Fibre Channel is a set of standards for connecting storage devices in a fabric network. The Fibre Channel standard identifies a protocol and a collection of physical interfaces for managing computer peripheral components. This standard’s key purpose is managing large numbers of storage devices. Fibre Channel uses serial interfaces working at symbol rates from 133MB/s …
Network Attached Storage (NAS) is a term used to describe a complete storage system which is designed to be attached to a traditional data network. This differentiates Network Attached Storage devices from SAN's (Storage Area Networks). A SAN is a separate network to which storage devices are attached. In most cases, Network Attached Storage is …
iSCSI (Internet Small Computer System Interface) is an IP-based storage networking standard that allows users to access data stored on a remote server from a number of computers within a specific network by linking computers over the Internet. It transfers data over local area networks, wide area networks, and the Internet. iSCSI places a shortcut …
A HBA (host bus adapter) is an integrated circuit adapter or circuit board that is designed to provide physical connectivity between a computer host and storage devices or a network. In addition to the physical connection, an HBA also provides input/output (I/O) processing and alleviates the host computer microprocessor from having to conduct data retrieval …
A NAS, or Network-Attached Storage, device is a type of hardware that allows all users in a network to store files to the same storage device. A NAS device is often used by companies who have large amounts of data that need to be accessed by multiple users within the same network. NAS devices are …
A World Wide Name, or WWN, is a 64-bit or 128-bit name assigned to each manufacturer of network storage devices and fiber channels by the Institute of Electrical and Electronics Engineers, or IEEE. Each network storage device that a manufacturer produces must include the manufacturer’s WWN, which is used to identify a network storage device …
A SAN (Storage Area Network) is a network specifically dedicated to the task of transporting data for storage and retrieval. SAN architectures are alternatives to storing data on disks directly attached to servers or on Network Attached Storage (NAS) devices that are connected through general purpose networks. In order to meet the storage system’s demands, …
