Information Technology (IT) provides both block and file storage services. Depending on the type of environment you wish to deploy, either may be the best solution for your user or systems data.
In its most basic form, block storage looks like a hard drive attached to a server, except the hard drive is installed in a remote chassis and is accessible using technologies such as Fibre Channel or iSCSI. Data is stored in "blocks" of a preset size. Storage volumes are created and systems connect to these volumes and use them as individual hard drives. Data protection is accomplished using scheduled backup jobs supported by IT.
File storage is often used to share files with users. The storage is often connected via protocols such as SMB (Server Message Block) ⁄ CIFS (Common Internet File System) or NFS (Network File System). The storage device handles the files and folders in the storage architecture. IT's Enterprise Network Attached Storage (eNAS) service is an example of file storage. Data protection is accomplished using replication across IT's infrastructure.
Unlike in block storage (in which the storage volume is created as blank space and an operating system is deployed and then attached to the created volume), in file storage, the storage itself handles the files and folders within the storage architecture. Throughput and performance generally are better via a block storage solution; however, your environment needs to be set up from the base operating system onward, while file storage allows you to "attach" to the allocated storage and allow your already-in-place server to mount⁄connect to the storage for use and placement of files.
