ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
Originally, version numbers of the pool and file system were incremented as new features were introduced, in order to designate the on-disk file system format and available features. This worked well when a single entity controlled the development of ZFS, and this versioning scheme is still in use with the ZFS in Oracle Solaris. [85] [86]
TrueNAS (formerly FreeNAS) is a family of network-attached storage (NAS) products produced by iXsystems, incorporating both open-source and commercial software. Based on the OpenZFS file system, TrueNAS runs on FreeBSD as well as Linux and is available under the BSD License .
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" [1] a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." [2] A "storage system" is also known as a storage array, disk array, or filer ...
Concatenation or spanning of drives is not one of the numbered RAID levels, but it is a popular method for combining multiple physical disk drives into a single logical disk. It provides no data redundancy. Drives are merely concatenated together, end to beginning, so they appear to be a single large disk, known as SPAN or BIG. [citation needed]
It also contrasts with shared-disk and shared-memory architectures. SN eliminates single points of failure , allowing the overall system to continue operating despite failures in individual nodes and allowing individual nodes to upgrade hardware or software without a system-wide shutdown.
Dell Technologies PowerFlex (previously known as ScaleIO and VxFlex OS), is a commercial software-defined storage product from Dell Technologies that creates a server-based storage area network (SAN) from local server storage using x86 servers.
GPFS (General Parallel File System, brand name IBM Storage Scale and previously IBM Spectrum Scale) [1] is a high-performance clustered file system software developed by IBM. It can be deployed in shared-disk or shared-nothing distributed parallel modes, or a combination of these.
