    A spindle is a shaft that holds rotating hard disk drive (HDD) platters in place. The term is also often used to refer to a single HDD.

  • standalone dump

    A standalone dump is the copying of the contents of computer main storage (random access memory) to another storage device, usually for the purpose of debugging a programming problem.

  • storage as a service (STaaS)

    Storage as a service can be delivered on premises from infrastructure that is dedicated to a single customer, or it can be delivered from the public cloud as a shared service that's purchased by subscription and is billed according to one or more usage metrics.

  • storage encryption

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

  • storage replication service

    A storage replication service is a managed service in which stored or archived data is duplicated in real time over a storage area network (SAN).

  • storage resource management (SRM)

    An important goal of storage resource management is to make it easier for storage administrators to reclaim unused storage

  • storage stack

    A storage stack, also called an integrated stack, is a bundled storage product that include servers, networking components and server virtualization software. 

  • storage virtualization

    Storage virtualization is the pooling of physical storage from multiple storage devices into what appears to be a single storage device -- or pool of available storage capacity -- that is managed from a central console.

  • switching fabric

    Switching fabric is the combination of hardware and software that moves data coming in to a network node out by the correct port (door) to the next node in the network.

  • T

    tebibyte (TiB)

    A tebibyte (TiB) is a unit of measure used to describe computing capacity.

  • Terabyte (TB)

    A Terabyte (TB) is a measure of computer storage capacity that is approximately 2 to the 40th power, or 10 to the 12th power, which equals approximately a trillion bytes.

  • thick provisioning

    Thick provisioning pre-allocates storage capacity on a disk rather than on an as-needed basis.

  • thin server

    In the computer industry, a thin server is a PC that contains just enough hardware and software to support a particular function that users can share in a network, such as access to files on a storage device, access to CD-ROM drives, printing, or Internet access.

  • two-spindle system (twin-spindle system)

    A two-spindle system, also called a twin-spindle system, is a computer design with two internal storage drives.

  • U

    UDO (ultra density optical)

    Ultra density optical (UDO) is an optical storage technology that increases capacities by using an extremely focused blue laser to write and read data.

  • Universal Disk Format (UDF)

    Universal Disk Format (UDF) is a CD-ROM and DVD file system standard developed as a means of ensuring consistency among data written to various optical media, by facilitating both data interchange and the implementation of the ISO/IEC 13346 standard.

  • V

    VMware Storage Policy-Based Management

    Storage Policy-Based Management is a feature that allows for automatic provisioning of virtual machines in a VMware environment.

  • W

    Windows Storage Spaces

    Windows Storage Spaces is a feature in Microsoft Windows Server 2012 that is used to virtualize and provision storage.

  • WORM (write once, read many)

    In computer storage media, WORM (write once, read many) is a data storage technology that allows information to be written to a disc a single time and prevents the drive from erasing the data.

  • X

    XAM (eXtensible Access Method)

    XAM (eXtensible Access Method) is a standard that makes it easier to manage fixed content by freeing data from dependencies on location, applications and storage devices.
