Azure File Storage, a component of Microsoft Azure’s broader cloud services, is a managed file storage service for the cloud. Its fundamental design is to create, manage, and share file systems securely and easily using standard protocols supported by most operating systems. It offers fully managed file shares in the cloud accessible via the industry-standard Server Message Block (SMB) and Network File System (NFS) protocols.
Key Protocols: NFS and SMB Explained
To comprehend Azure File Storage fully, we must unpack the two critical protocols it uses: NFS and SMB.
NFS: Detailed Technical Overview
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems. The protocol, based on the Remote Procedure Call (RPC) model, allows all network users to access shared files stored on computers of different types.
The latest version supported by Azure, NFS 4.1, introduces several enhancements over previous versions:
Stateful and Stateless Operations: NFS 4.1 supports both stateful and stateless operations. While stateful operations require the server to maintain state information, stateless operations do not. Stateful operations include actions such as locking files, while stateless operations include reading and writing to files.
Compound Operations: NFS 4.1 also introduces compound operations. In previous versions of NFS, each operation sent over the network would necessitate a response before another could be sent. Compound operations allow clients to send multiple operations to the server in a single request, reducing the latency associated with waiting for responses.
Security Enhancements: NFS 4.1 offers better security with the Kerberos V5 authentication protocol. It also uses string-based names to identify users and groups, which eases the integration of NFS into a multi-domain environment.
SMB: In-depth Technical Examination
Server Message Block (SMB) is a networking file share protocol included in Windows 10 that provides the ability to read and write files and perform other service requests to network devices. SMB operates as an application-layer network protocol mainly used for offering shared access to files, printer access, serial ports, and miscellaneous communications between nodes on a network.
Azure supports SMB 3.1.1 protocol, which has several improvements:
Persistent Handles: SMB 3.1.1 supports persistent handles, which are durable handles that can withstand brief network disruptions without disconnecting the user’s session. This provides users with a continuous connection even when there are network interruptions.
Multichannel: SMB 3.1.1 also introduces multichannel, which allows clients to establish multiple network paths for the SMB session. This not only increases performance by enabling concurrent network input/output (I/O), but it also provides redundancy and failover capabilities.
Encryption: To increase security, SMB 3.1.1 offers end-to-end encryption. This ensures that data is not compromised while in transit over the network, providing additional security for sensitive data.
