MooseFS Chunk Servers
Port 9422 is used by MooseFS, an open-source distributed file system designed to provide fault tolerance, high availability, and scalability. This port specifically facilitates communication between chunk servers and clients, enabling clients to directly access or store data blocks across the distributed storage network..
MooseFS Overview: MooseFS is a fault-tolerant, POSIX-compliant distributed file system that allows a large number of commodity servers to be combined into a single storage pool. Its architecture separates metadata and chunk (data block) management, with dedicated chunk servers storing file chunks and metadata servers managing the filesystem hierarchy.
Role of Port 9422: Port 9422 is primarily used to handle data transfer between MooseFS chunk servers and clients. When a client requests a file, it retrieves metadata (file location information) from the metadata server and then communicates directly with chunk servers over this port to access or modify data blocks.
Protocols and Traffic: Data transfer over port 9422 generally occurs via TCP, ensuring reliable, ordered delivery. Since data operations can be large and frequent, this port is optimized for performance but does not include encryption by default, relying instead on network-level security or additional encryption layers if required.
