Storage-Hypervisor
A storage hypervisor is in information technology a transferable to different hardware and applicable computer program with comprehensive storage management functionality, which brings together heterogeneous storage capacity in a virtual pool and increases the availability, speed and flow of the entire system.
A storage hypervisor can be installed on a hardware platform ( x86 servers ) and on a virtual machine where it resides exclusively for virtual machines, or in addition to a supervisor software. The storage hypervisor software is similar to a hypervisor for virtual servers, flexible migrated to one or more virtual or physical machines.
Through the use of a storage hypervisor, the utility and application value of disk subsystems ( disk subsystems ) can be increased in business by the incompatibilities of the hardware systems are eliminated with each vendor-specific administration software. Instead, the storage hypervisor integrated management functionalities for storage provisioning, data backup, replication and performance acceleration can be applied by caching on all hardware systems.
In contrast to built-in software (embedded software ) or the firmware of a disk controller storage hypervisors are offered as a software suite or as an appliance. The administration, management and maintenance functions of the storage hypervisor independently of make, model or technology of storage hardware in different storage topologies, such as Storage Area Network (SAN ), Direct Attached Storage (DAS ), or Unified Storage (SAN and NAS) available. In addition to HDD technology and Solid State Disks ( SSD ) are integrated into the storage pool.
The storage hardware limited by the use of a storage hypervisor only the capacity and performance of the overall system. The advantage lies in the possibility of setting up virtual storage drives on any replaceable hardware flexible and reversible with no interruption in service and with different qualities of service (performance, availability) and storage services ( auto-provisioning, replication ) for the entire corporate network centrally equip.
The term " storage hypervisor " establishes itself, because it is conceptually one level above the supervisor and thus over the intelligence of a device-specific RAID controller, disk arrays or settled a middleware for virtualization. Thus, the storage hypervisor is the advancement of storage virtualization software-based and is described as a "comprehensive set of storage control and monitoring functions operating as a transparent virtual layer across Consolidated disk pools to Improve Their availability, speed and utilization". The term was first used in a narrower sense in technical articles for data migration in SANs and to describe the hypervisor role in disaster recovery scenarios. In German IT trade media he appears in his overarching importance from 2011.
