storage hypervisor

A storage hypervisor, also called software-defined storage, is a marketing term for software that allows storage to be controlled centrally in a storage pool regardless of what hardware the storage is located on. A storage hypervisor abstracts capacity from storage hardware and aggregates it into pools so there is greater storage availability and performance. The software can ...

Microsoft Hyper-V Quick Migration

Hyper-V Quick Migration is a feature that allows users to move running virtual machines (VMs) from one host to another with minimal downtime. Live Migration replaced Quick Migration in Windows Server 2008 Hyper-V R2 and has been part of every subsequent release. The amount of time it takes to start a virtual machine on another ...

Microsoft Hyper-V Integration Services

Hyper-V Integration Services is a suite of utilities in Microsoft Hyper-V, designed to enhance the performance of a virtual machine’s guest operating system. Hyper-V Integration Services optimizes the drivers of the virtual environments to provide end users with the best possible user experience. The suite improves virtual machine management by replacing generic operating system driver files for the mouse, keyboard, ...

Storage vMotion

Storage vMotion is a component of VMware vSphere that allows the live migration of a running virtual machine’s (VM)  file system from one storage system to another, with no downtime for the VM or service disruption for end users. This migration occurs while maintaining data integrity. VMware Storage vMotion begins the process by copying the VM’s metadata , found in ...

vStorage APIs for Storage Awareness (VASA)

vStorage APIs for Storage Awareness (VASA) is a set of application program interfaces (APIs) that enables vSphere vCenter to recognize the capabilities of storage arrays. Such capabilities, including RAID, native thin provisioning and deduplication, are made visible within vCenter. This visibility makes it easier for virtualization and storage administrators to  make decisions about how data stores should be maintained — for ...

vStorage API

A vStorage API is an application program interface (API) from VMware that enables third-party storage and backup vendors to integrate their products with VMware’s vSphere server virtualization platform. As of September 2011, VMware provides four APIs for third-party vendors: vStorage APIs for Data Protection (VADP) — enables backup applications to perform file- or VM-level backup of running virtual ...

vStorage API for Multipathing (VAMP)

vStorage API for Multipathing (VAMP) is a set of application program interfaces (APIs) from VMware that help to control I/O path selection in a host to storage devices. The multipathing APIs  provide storage path failover, thereby optimizing storage I/O throughput and adding intelligence beyond the default pathing policies used by storage devices. For a storage administrator to make ...

vStorage APIs for Array Integration (VAAI)

vStorage API for Array Integration (VAAI) is an application program interface (API) framework from VMware that enables certain storage tasks, such as thin provisioning, to be offloaded from the VMware server virtualization hardware to the storage array. Offloading these tasks lessens the processing workload on the virtual server hardware. For a storage administrator to make use of VAAI, the manufacturer of ...

Storage Distributed Resource Scheduler (DRS)

VMware DRS (Distributed Resource Scheduler) is a load balancing utility that assigns and moves computing workloads to available hardware resources in a virtualized environment. DRS can be configured to recommend workload balancing or to automatically move workloads. VMware DRS users can refine resource allocation with affinity rules and anti-affinity rules. The utility allows VMware administrators to prioritize resources according ...
