Introduction to Brocade Network OS

Brocade Network OS is a scalable network operating system available for the Brocade data center switching portfolio products, including the VDX product line.

Purpose-built for mission-critical, next-generation data centers, Network OS supports the following capabilities:

Table 1 Network OS capabilities

Simplified network management

Brocade Virtual Cluster Switching (VCS) fabrics are self-forming and self-healing, providing an operationally scalable foundation for very large or dynamic cloud deployments. Multi-node fabrics can be managed as a single logical element, and fabrics can be deployed and easily re-deployed in a variety of configurations optimized to the needs of particular workloads.

For more information on Brocade VCS Fabric technology, refer to Introduction to Brocade VCS Fabric technology for an overview and Configuring Brocade VCS Fabrics for configuration details.

High resiliency

Brocade VCS fabrics use hardware-based Inter-Switch Link (ISL) Trunking to provide automatic link failover without traffic interruption.

Improved network utilization

Transparent Interconnection of Lots of Links (TRILL)-based Layer 2 routing service provides equal-cost multipaths in the network, resulting in improved network utilization. Brocade VCS Fabric technology also delivers multiple active, fully load-balanced Layer 3 gateways to remove constraints on Layer 2 domain growth, eliminate traffic tromboning, and enable inter-VLAN routing within the fabric.

Virtual Router Redundancy Protocol (VRRP) eliminates a single point of failure in a static, default-route environment by dynamically assigning virtual IP routers to participating hosts. The interfaces of all routers in a virtual router must belong to the same IP subnet. There is no restriction against reusing a virtual router ID (VRID) with a different address mapping on different LANs.

Refer to Fabric overview for additional information about TRILL.

Refer to the “VRRP overview” section of the Network OS Layer 3 Routing Configuration Guide for additional information on VRRP/VRRP-E.

Server virtualization

Automatic Migration of Port Profile (AMPP) functionality provides fabric-wide configuration of network policies, achieves per-port profile forwarding, and enables network-level features to support Virtual Machine (VM) mobility.

Refer to the “Configuring AMPP section” of the Network OS Layer 2 Switching Configuration Guide for more information about AMPP.

Network convergence

Data Center Bridging (DCB)-based lossless Ethernet service provides isolation between IP and storage traffic over a unified network infrastructure. Multi-hop Fibre Channel over Ethernet (FCoE) allows an FCoE initiator to communicate with an FCoE target that is a number of hops away.

Refer to the "End-to-end FCoE" section of the Network OS Layer 2 Switching Configuration Guide for more information about multi-hop FCoE.

In Network OS, all features are configured through a single, industry-standard command line interface (CLI). Refer to the Network OS Command Reference for an alphabetical listing and detailed description of all the Network OS commands.
