Additionally, the storage virtualization technique makes it possible to produce a virtualized disk in the 'disk pool' which was created by drawing unused disks left in the several physical storage systems.
The same kinds of virtualization techniques have already happened with data storage, but networks, which have more parts and functions, are tougher to virtualize.
Virtualization techniques effectively handle the growing demand for computing, storage, and communication resources in large-scale Cloud Data Centers CDCCloud Data Centers CDC
With recent developments in NVMe devices, with supporting infrastructure, and, virtualization techniques, a hybrid approach of using heterogeneous tiers of storage together such as those having HDDs and SSDs coupled with workload-aware tiering to balance cost, performance and capacity have become increasingly popular [1, 3, 12, 25].
Table 1 Virtualization techniques Technique Description Examples Full virtualization The Virtual Machine Monitor emulates a complete machine, based on the underlying hardware architecture.
Current trends bear out that virtualization techniques are no longer limited to computers as virtual machines.
If the user needs to minimize the virtualization overhead, the virtual machines can be created using lightweight OS-level virtualization techniques such as LXC [11].
Recent advances in networking and virtualization techniques allowed us to move Xenbase to a virtual environment, and more specifically to a private cloud.
Storage virtualization refers to the separation of physical disk space from the logical assignment of that space, using various techniques (e.g. RAID and SAN).
In this approach, machine virtualization techniques play a fundamental role.
The ideal storage virtualization system is compatible with all operating systems in storage area networks (SANs).
