Brocade Virtual Traffic Manager 11.1 released


This new release of Brocade vTM extends the performance and capability of the new Data Plane Acceleration (DPA) mode, first introduced in Brocade vTM 11.0. This new architecture allows lower-latency and higher-throughput traffic management, and can drive up to 120 Gbps L4 throughput and 1 million L4 connections per second on commodity x86 hardware. This means Brocade vTM can now deliver a combination of high L4 throughput and rich L7 services.

As with previous versions of Brocade vTM, this latest version can be managed using Brocade Services Director, allowing shared resource pooling with other vTM instances. This gives the flexibility of a capacity-based licensing model and very high L4 performance.

Highlights in this release include:

  • High-Performance L4 services - The new Layer 4 stack in Brocade vTM is extremely lightweight, and delivers low latency and high performance load balancing, and supports linear scaling of CPS and throughput with additional CPU cores, unlike traditional kernel network stacks. More than one million L4 connection requests per second are achievable on supported platforms.

  • Platform support - In this release, Data Plane Acceleration mode and L4 services are supported in the VMware and KVM/QEMU virtual appliances.

  • L4 Server Load-Balancing - Support for L4 Server Load Balancing, including failover pool selection, IP session persistence, IP Transparency, Source-IP NAT, health monitoring and bandwidth management. This release also includes support for both stateless and stateful L4 services.

  • L4 Stateful failover - In a cluster, Brocade vTM now supports synchronization of the Layer 4 connection state for stateful failover between cluster members. If a vTM instance is lost, the standby vTM becomes active and continues to process the connections that were actually established by the failed Traffic Manager. This presents a seamless experience to the end user.

  • Bare Metal Appliance Image - Support for more qualified, hardware platforms including HP DL380 servers. In addition, DPA mode is now supported by the Bare Metal appliance image. See the Hardware Compatibility list for full details at

  • Brocade vWAF - For customers who are using the Brocade Virtual Web Application Firewall, there is a new-style user interface for the Cluster Update Center (CUC). This new interface provides easier access to key functions, such as automated deployment and upgrade of cluster members, and simple access to review the Audit Log.
