In a Network Attached Storage (NAS) environment, the Common Internet File System (CIFS) enables file sharing with Windows clients and uses the TCP/IP protocol. CIFS is an enhanced version of the Server Message Block (SMB) protocol, which allows multiple users to access and share files over a network. It is commonly used in Windows environments for network file sharing and supports various operations like file read/write, file locking, and more.References:= Dell Information Storage and Management V5 course materials

The Cisco MDS-9132T switch model supports NVMe over Fibre Channel (FC) in a 32Gb/s SAN fabric.
NVMe (Non-Volatile Memory Express) is a protocol designed for SSDs to exploit the performance potential of flash technology and provides faster data access compared to traditional SCSI protocols. The MDS-9132T is optimized for modern data centers requiring high-performance storage connectivity.

an FC frame consists of five parts: start of frame (SOF), frame header, data field, cyclic redundancy check (CRC), and end of frame (EOF). The SOF and EOF act as delimiters. The frame header is 24 bytes long and contains addressing information for the frame.
