Brocade VDX 6746 Switch

What is it?

  • State-of-the-art 10 Gigabit Ethernet with DCB/FCoEembedded switch for the Hitachi CB500 blade server platform

  • Enables Hitachi CB500 to support flexible connectivity options for cloud architectures, including lossless Ethernet fabrics 

  • Provides CB500 customers the choice to enhance their hierarchical network architectures, deploy flatter scale-out fabrics or converge networks when deploying virtualization and cloud IT infrastructures. 

  • Designed to increase scalability and enhance VM mobility, further simplifying management and significantly reducing operational overhead of virtualized blade server environments

  • L3 features allow elimination of the second external aggregation layer


VDX 6746: New 10GE DCB switch MODUle

Brocade VDX 6746

  • Industry’s 1st Ethernet Fabric enabled embedded 10Gb DCB switch module

    • flexible connectivity options for cloud architectures

      • Simplify and enhance hierarchical network architectures

      • deploy flatter scale-out fabrics ***

      • converge networks

  • Brocade VDX 6746 supports

    • 24 x 10GE ports (16 internal, 8 external)

    • Non-blocking, cut through architecture, wire speed

    • Dual speed (1GE/10GE) external ports

    • 1 Gb RJ-45 connectors and 10 Gbtwinax copper or optical connectors

    • Brocade Virtual Cluster Switching (VCS)

    • DCB and multi hop FCoE

    • Automatic Migration of Port Profiles (AMPP)

    • Rich set of Layer 2 and Layer 3 features

    • Hitachi Chassis Management Support


Benefits of VDX 6746

  • Embedded design dramatically reduces cabling, power and cooling

  • Industry-leading performance and ultra-low latency

  • Simplifies network architectures and enables cloud computing by delivering Brocade Virtual Cluster Switching (VCS) technology and enabling Ethernet fabrics

    • VCS technology deploys scale-out fabrics instead of a hierarchical network to flatten the network design, and manages the entire fabric as a single Logical Chassis to reduce complexity

    • Compared to classic Ethernet architectures, Ethernet fabrics allow all paths to be active, increasing network performance, utilization, and resiliency

  • Supports lossless unified storage connectivity, and storage and LAN traffic convergence to reduce connectivity cost

  • Simplifies virtualized server management by enabling seamless Virtual Machine (VM) mobility

  • Can be deployed into classic 1Gb and 10Gb architectures, preserving existing network designs and cabling

  • Enables end-to-end management of CB500


  • Virtual Cluster Switching (VCS)

  • Scale-out, multi-path, highly resilient layer 2 Ethernet Fabric

  • Self-forming and masterless through Distributed Intelligence

Virtual Machine Mobility

Challenges Today

  • Limited sphere of mobility

    • STP limits flexibility to a minimized, defined tree of switches

    • L3 limits mobility to a single rack

  • VM migration can break network/application access

    • Port setting information must be identical at destination

  • Map services (VLANs, QoS, security, etc.) to all physical ports

    • Eases mobility, but undermines network and security best practices

  • Distributed Virtual Switch

    • Addresses configuration needs

    • Consumes server resources and still restricted by physical limits

  • Limited insight into where VMs are running

    • VMs exist anywhere in thecluster

VM Mobility with VDX 6746 & VCS

Automatic Migration of port profiles (AMPP)

  • Distributed intelligence of VM location throughout VCS fabric

  • Granular VLAN, ACL, and QoS policies assigned per VM

  • Zero network re-configuration required when a VM is moved across the VCS fabric

NOS 3.0: Native l3 support in vcs fabric

Efficient Forwarding

Benefits:

  • Inter VLAN (routed) traffic no longer has to go to core for routing.

    • Less hops, less latency

  • VRRP-E load balances L3 traffic between aggregation VDX routers

    • Better link utilization, Faster recovery

      Use Cases:

  • Services (firewall, SLB, etc) can hang off VDX router at aggregation.

    • Eliminate second external aggregation layer
