Storage management and analytics Definitions

  • M

    MTTR (mean time to repair)

    MTTR (mean time to repair) is the average time required to fix a failed component or device and return it to production status.

  • N

    nearline storage

    Nearline storage is the on-site storage of data on removable media.

  • NetApp Data Fabric

    The products and services that compose NetApp’s Data Fabric are designed to provide customers with the agility they need to quickly and efficiently move data to and from the cloud.

  • non-disruptive data migration

    Non-disruptive data migration is a feature that allows data movement from one storage device to another without causing downtime in the environment.

  • non-disruptive upgrade (NDU)

    A non-disruptive upgrade (NDU) is an update to software or hardware done without interruption to system service or data access.

  • non-volatile memory (NVM)

    Non-volatile memory (NVMe) is a semiconductor technology that does not require a continuous power supply to retain the data or program code stored in a computing device.

  • O

    ODCA (Open Data Center Alliance)

    The Open Data Center Alliance (ODCA) is an independent information technology (IT) consortium whose goal is to develop a unified vision of cloud requirements.

  • open source cloud storage

    Open source cloud storage is a cloud storage architecture that uses freely available source code to build and manage a private cloud storage platform.

  • open source storage

    Open source storage is data storage software developed in a public, collaborative manner that permits the free use, distribution and modification of the source code.

  • orthogonal

    Orthogonal concepts have their roots in advanced mathematics. They are also associated with software development, storage and networking.

  • P

    persistent storage

    Persistent storage is any data storage device that retains throughout instances of lost power.

  • petabyte (PB)

    A petabyte is a unit of data storage space consisting of 1,024 terabytes, or approximately 1 million gigabytes. The prefix 'peta' refers to the fifth power of 1,000.

  • pipeline burst cache

    A pipeline burst cache is a cache or storage area for a computer processor that is designed to be read from or written to in a pipelining succession of four data transfers (or bursts) in which later bursts can start to flow or transfer before the first burst has arrived at the processor.

  • portability

    Portability is a characteristic attributed to a computer program if it can be used in an operating systems other than the one in which it was created without requiring major rework.

  • production data

    Production data is data that is persistently stored and essential to completing day-to-day business tasks and processes.
