# Witness Protocol Feature - Detailed Design Document

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.

## 2. Protocol Specification Reference

- **MS-SWN**: Service Witness Protocol Specification

# Directory Leasing Feature - Detailed Design Document

## 1. Overview

Directory leasing extends the SMB3 lease concept to directories, enabling client-side caching of directory metadata and change notifications. This significantly improves performance for applications that frequently enumerate directories or monitor directory changes.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.12**: SMB2_CREATE_REQUEST_LEASE_V2 for directories

# SMB3 Lease Feature - Detailed Design Document

## 1. Overview

SMB3 leases provide a client caching mechanism that replaces the traditional oplock mechanism. Leases enable better performance through client-side caching while maintaining cache coherency across multiple clients.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13**: SMB2 CREATE Request with Lease Context
- **MS-SMB2 Section 2.2.14**: SMB2 CREATE Response with Lease State

# Persistent Handles Feature - Detailed Design Document

## 1. Overview

Persistent handles (also known as durable handles) allow SMB3 connections to survive network disconnections, server reboots, and client reconnections. This feature is critical for enterprise reliability and seamless failover scenarios.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.3**: SMB2_CREATE_DURABLE_HANDLE_REQUEST

# Multi-Channel Feature - Detailed Design Document

## 1. Overview

SMB3 Multi-Channel enables the use of multiple network connections between client and server, providing increased throughput, network fault tolerance, and automatic failover capabilities. This feature aggregates bandwidth across multiple NICs and provides seamless failover when network paths fail.

## 2. Protocol Specification Reference

# RDMA (SMB Direct) Feature - Detailed Design Document

## 1. Overview

SMB Direct enables high-performance data transfer using Remote Direct Memory Access (RDMA) technology. This provides ultra-low latency and high bandwidth data transfer by bypassing the traditional TCP/IP stack and allowing direct memory-to-memory transfers between client and server.

## 2. Protocol Specification Reference

- **MS-SMBD**: SMB2 Remote Direct Memory Access (RDMA) Transport Protocol
