A virtual storage area network (virtual SAN, VSAN or vSAN) is a logical representation of a physical storage area network (SAN). A VSAN abstracts the storage-related operations from the physical storage layer, and provides shared storage access to the applications and virtual machines by combining the servers' local storage over a network into a single or multiple storage pools.
VMFS-L is the underlying file system for VSAN-1.0. Leaf level VSAN objects reside directly on VMFS-L volumes that are composed from server side direct attached storage (DAS). File system format is optimized for DAS. Optimization include aggressive caching with for the DAS use case, a stripped lock down lock manager and faster formats.
System Center Virtual Machine Manager (SCVMM) forms part of Microsoft's System Center line of virtual machine management and reporting tools, alongside previously established tools such as System Center Operations Manager and System Center Configuration Manager.
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.
VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox.
Targets can be made incremental, and cascaded tree like dependency structures can be constructed. Targets can be re-applied to their source or any other appropriate volume, also of different size (e.g. resetting any changes from a resize command). Copy-on-write is based on a bitmap with a configurable grain size, as opposed to a journal. [1]
Dell EMC Unity is one of Dell EMC's mid-range storage array product lines. It was designed from the ground up as the next-generation midrange unified storage array after the EMC VNX and VNXe series, which evolved out of the EMC Clariion SAN disk array.
In computing, a virtual address space (VAS) or address space is the set of ranges of virtual addresses that an operating system makes available to a process. [1] The range of virtual addresses usually starts at a low address and can extend to the highest address allowed by the computer's instruction set architecture and supported by the operating system's pointer size implementation, which can ...
