  • Remote Direct Memory Access (RDMA)

    Remote Direct Memory Access (RDMA) is a technology that allows computers in a network to exchange data in main memory without involving the processor, cache, or operating system of either computer.

  • storage security

    Storage security is the group of parameters and settings that make storage resources available to authorized users and trusted networks - and unavailable to other entities.

  • buffer credits or buffer-to-buffer credits (BBCs)

    Buffer credits, also called buffer-to-buffer credits (BBCs), allow data communication in a Fibre Channelstorage area network (SAN) where there are long spans of fiber opticcable.

  • SAN routing

    SAN (storage area network) routing is a technology used for interconnecting SAN islands (separately designated logical portions of a storage area network) within a larger network.

  • backup storage

    In computers, backup storage is storage that is intended as a copy of the storage that is actively in use so that, if the storage medium such as a hard disk fails and data is lost on that medium, i...

  • archival storage

    In computers, archival storage is storage for data that may not be actively needed but is kept for possible future use or for record-keeping purposes.

  • information life cycle management (ILM)

    Information life cycle management (ILM) is a comprehensive approach to managing the flow of an information system's data and associated metadata from creation and initial storage to the time when i...

  • double-parity RAID

    Double-parity RAID (redundant array of independent disks), also called diagonal-parity RAID, Advanced Data Guarding (RAID_ADG), or RAID-6, is a method of protecting against multiple storage drive f...

  • bit padding

    Bit padding is the addition of one or more extra bits to a transmission or storage unit to make it conform to a standard size.

  • yottabyte

    A yottabyte is a measure of theoretical storage capacity and is 2 to the 80th power bytes or, in decimal, approximately a thousand zettabytes, a trillion terabytes, or a million trillion megabytes.

  • failover

    Failover is a backup operational mode in which the functions of a system component (such as a processor, server, network, or database, for example) are assumed by secondary system components when t...

  • SMI-S (Storage Management Initiative Specification)

    SMI-S (Storage Management Initiative Specification) is a standard developed by the Storage Network Industry Association (SNIA) that is intended to facilitate the management of storage devices from ...

  • storage utilization

    Storage utilization is a measure of how well the available data storage space in an enterprise is used.

  • business impact analysis (BIA)

    Business impact analysis (BIA) is an essential component of an organization's business continuance plan; it includes an exploratory component to reveal any vulnerabilities, and a planning component...

  • storage distance extension

    Storage distance extension refers to any of several different technologies that allow data communication in Fibre Channel storage area networks (SANs) over long spans of fiber optic cable.

  • SerDes (serializer/deserializer)

    A SerDes or serializer/deserializer is an integrated circuit (IC or chip) transceiver that converts parallel data to serial data and vice-versa.

  • storage area management (SAM)

    Storage area management (SAM) is a still-evolving set of procedures, services, and standards for comprehensively managing the infrastructure of a storage area network (SAN), including all component...

  • intelligent switch

    An intelligent switch is a high-level storage area network (SAN) routing switch that provides features such as storage virtualization, quality of service (QoS), remote mirroring, data sharing, prot...

  • SAN file system

    A SAN file system (that is, a storage area network file system) is programming that enables the sharing of the same copies of files stored on common storage media among multiple servers that may ha...

  • storage encryption

    Storage encryption is the use of encryption/decryption of backed-up and archived data, both in transit and on storage media.
