Network

The ZX2000 is offered with two network speed options. The 10G ZX2010 provides a redundant 10G network to all of the installed blades for a total of 60Gbps backplane capacity and 60Gbps of egress via 6 front panel SFP+ ports. The front panel ports can be configured to operate at 1G or 10G over copper and fiber for flexibility in network integration. With the ZX2040, the ZX2000 5U ATCA blade server can provide up to 480G on the backplane to fulfill the most demanding data plane applications. Four QSFP ports are available on the front panel, these ports can operate as 40G egress ports or with an optional breakout cable, 16 10G ports. Both switch options feature the OpenArchitect® Ethernet Management software which provides users with the familiar Linux networking environment with advanced protocol support and scriptable environment for easy configuration.

Control and Data plane Separation

The ZX2000 includes two network fabrics for complete control and data-plane separation. A high-speed 10G or 40G network creates a data-path for user traffic that is isolated from internal control traffic that runs between the application blades. No matter what happens on the data plane, the control plane can be kept isolated and secure, assuring total control over the network at all times.

Egress to Backplane Bandwidth

A careful, balanced approach went into the design of the ZX2000 network subsystem. In typical 14 slot blade server systems, egress ports remain the congestion point starving the high-bandwidth traffic between the application blades. The ZX2000 solves this by providing a high ratio of egress to backplane bandwidth.

The ZX2000 with 10G switch provides a perfect 1:1 ratio of egress/backplane bandwidth with 60Gbps dedicated to each. Typical 14 slot applications have a backplane capacity of 120 Gbps, but egress ports are typically limited to 70Gbps with a backplane to egress ratio of 1.7:1. Typical 14 slot 40G systems extend the bandwidth mismatch to 4:1 with a typical backplane bandwidth of 480Gbps to 120Gbps for egress. The 40G configuration of the ZX2000 balances this mismatch with a 1.5:1 ratio providing 240Gbps capacity on the backplane with 160Gbps egress, reducing the network bottleneck.
