![]() ![]() The simplicity of file storage makes it a great solution for sharing a large number of files and folders within an organization. ![]() The servers accessing file storage do not need to deal with the complexity of managing the blocks, formatting volume, etc. File storage could be made accessible by a large number of servers using common file-level network protocols like SMB/CIFS and NFS. File storage is the most common general-purpose storage solution. Data is stored as files under a hierarchical directory structure. It provides a higher-level abstraction to make it easier to handle files and directories. It is not a shared resource.įile storage is built on top of block storage. Whether to a network or physically attached, block storage is fully owned by a single server. To the servers, it works the same as physically attached block storage. Conceptually, the network-attached block storage still presents raw blocks. Block storage could be connected to a server over a high-speed network or over industry-standard connectivity protocols like Fibre Channel (FC) and iSCSI. Some applications like a database or a virtual machine engine manage these blocks directly in order to squeeze every drop of performance out of them.īlock storage is not limited to physically attached storage. The server can format the raw blocks and use them as a file system, or it can hand control of those blocks to an application. This is the most flexible and versatile form of storage. Common storage devices like hard disk drives (HDD) and solid-state drives (SSD) that are physically attached to servers are all considered as block storage.īlock storage presents the raw blocks to the server as a volume. ![]()
