Storage Virtualization types: advantages and disadvantages (Part 2-2)
Operating system level Storage virtualization
Some working systems give the same fundamental virtualization-based storage array, however at the product level as a component of the working system capacities. Windows Server 2012 and 2012 R2, for instance, incorporate an element called Windows Storage Spaces, which permits the formation of layered storage through virtualization.
File system virtualization
Virtualization file system alludes to advancements, for example, Distributed File System Microsoft (DFS), which give a combined data file of an association view. Clients have the hallucination that all data exist on a solitary file server, when truth be told the data might be scattered over a few distinct parts of server message square (SMB) in numerous file servers. Virtualization file system is turning out to be less regular because of the expanded storage limit of the file server, yet at the same time utilized.
A few types of file system virtualization accomplish more than simply join SMB offers utilizing a typical namespace. A few, for example, Microsoft DFS, additionally permit replication of file system, which can be valuable when an association needs to permit clients working in a remote office to get to the same files that clients of the primary office, however without downloading files over a WAN connection.
Fiber Channel Storage virtualization
Storage virtualization Fiber Channel (Fiber Channel or FC) is a non specific term for sorts of storage virtualization worked around the utilization of FC. A few sellers allude to a SAN FC as a type of storage virtualization based system because of the way a FC switch can virtualize and divert demands for I/O to the physical storage without the server devouring that storage knows about the fundamental storage design.
The term storage virtualization FC can likewise allude to virtual FC. Virtual FC is a type of storage virtualization host-based, yet works diversely utilize shapes most generally utilized storage virtualization host.
Virtual FC is an instrument that empowers a VM to associate specifically to an array FC or FC SAN by utilizing the fundamental virtualization stack. The principle advantage of virtual FC is that it permits an immediate reliance servers to storage to be virtualized FC. You can likewise utilize virtual FC in making a visitor group utilizing bunch shared volumes based on FC.
It is important that the confinements and abilities of the virtual FC differ starting with one hypervisor then onto the next. Microsoft Hyper-V, for instance, VM can not boot from virtual storage appended to FC.
