Block Level and File Level
The document discusses storage virtualization, which can be implemented at the block level or file level, each with distinct advantages. Block-level storage is typical for larger enterprises and allows individual blocks to be managed like hard drives, while file-level storage simplifies implementation and management by handling files and directories. The virtualization process abstracts physical storage, enabling flexible management of storage capacity for applications and users.

- 2. Storage virtualizationcan be implemented in following ways. Each has its own advantages and disadvantages
- 3. Virtualization onblock level means that storage capacity is made available to the operating system or the applications in the form of virtual disks In virtualization on block level the task of file system management is the responsibility of the operating system or the applications The task of the virtualization entity is to map these virtual blocks to the physical blocks of the real storage devices
- 5. Virtualization onfile level means that the virtualization entity provides virtual storage to the operating systems or applications in the form of files and directories The applications work with files instead of blocks and the conversion of the files to virtual blocks is performed by the virtualization entity itself This means, the task of file system management is performed by the virtualization entity, unlike in block level which is done by OS or application The physical blocks are presented in the form of a virtual file system and not in the form of virtual blocks.
- 7. Block-level storageis a type of storage commonly deployed by larger businesses and enterprises in storage area networks (SANs) and similar large-scale storage systems. Each block in a block-level storage system can be controlled as an individual hard drive, and the blocks are managed by a server operating system. Block-level storage protocols like iSCSI, Fibre Channel and FCoE (Fibre Channel over Ethernet) are utilized to make the storage blocks visible and accessible by the server-based operating system. This is in contrast with file-level storage, in which the storage drives are configured with a storage protocol like NFS or SMB/CIFS.
- 8. Another keydifference between block-level storage and file- level storage is that while individual files and folders can be accessed and managed by the storage system in file-level storage, these storage systems are unable to directly control the smaller storage blocks that make up the files and folders. File-level storage is simple to implement and use, and it's also less expensive to manage than block-level storage, which are key reasons for it being the predominant storage technology used on hard drives, network-attached storage (NAS) systems and similar storage systems. In virtualization the only difference is these storages are created by virtualization technology and so these storage does not have a Physical devices its only virtualized
- 9. Block-level storagevirtualization is a storage service that offers a flexible, logical arrangement of storing capacity to applications and users while abstracting its physical location. As a software layer, it catches I/O requests to that logical capacity and maps them to the suitable physical locations. In computing, file virtualization is a field of storing virtualization operating on the computer file level. It includes uniting multiple storage devices into a single logical pool of files.
