VM-aware storage is computer data storage designed specifically for managing storage for virtual machines (VMs) within a virtual infrastructure. The goal is to provide storage that is simpler to use with functionality better suited for VMs compared with general-purpose SAN, NAS or DAS storage. VM-aware storage allows storage to be managed as an integrated part of managing VMs rather than as LUNs or volumes that are separately configured and managed. VM-aware storage is often used in conjunction with other VM-aware infrastructure components and processes such as VM-aware networking, VM-aware backup and VM-aware virus scanning to give a few examples.〔 VM-aware infrastructure has some similarities to and can benefit from software-defined infrastructure components, but is distinct in that the latter provides general purpose physical infrastructure that can be customized and configured in software whereas VM-aware infrastructure is specialized and designed for virtual infrastructures.〔〔 ==Background== Adoption of server virtualization technology increased rapidly since the launch of the VMware ESX hypervisor in 2001. By 2009, IDC estimated that more VMs were being deployed than physical machines.〔 The ability to consolidate applications running on tens of servers in a single physical server running a hypervisor resulted in dramatic cost savings for servers as well as more automated management of the servers. Due to these advantages, by early 2010, many companies had implemented "virtualization first" policies, which stated that all new server deployments should be virtual unless there were specific reasons to use a physical server.〔 As virtualization decreased the cost of the server infrastructure, storage began to dominate the cost and complexity of virtual infrastructures. In almost all virtual infrastructures in the early 2000s, computing resources, such as CPU and memory, were configured and managed separately from the storage resources. Server infrastructure was often managed by a separate team than the storage infrastructure. Configuring the servers and storage separately and trying to get them to work together often required significant advanced planning, integration and troubleshooting. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VM-Aware Storage」の詳細全文を読む スポンサード リンク
