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:
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.
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.
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.
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.
