Overview<\/p>\n<\/div>

<\/div><\/div>

The Edgecore EXP400-32X is a high performance, low power, low latency, fully programmable SDN data center switch designed for data center, cloud, and AI networks.<\/p>\n<\/div>

<\/i><\/div>

Leaf or ToR switch<\/h3><\/div>
<\/div>
\n

The EXP400-32X is a 32-QSFP112-port switch in a 1RU form factor. Each of the QSFP112 ports can breakout to 2 x 200G, or 4 x 100G, optimizing compute racks by enabling 100Gbps-per-lane server links and 400G uplink optics. The device is an ideal leaf or ToR switch for cloud data center operators that are driving the rapid adoption of 400Gbps optical modules while also upgrading compute server NICs to 400Gbps speeds.<\/p>\n<\/div><\/div><\/div>

<\/i><\/div>

Xsight Instruction Set Architecture (ISA)<\/h3><\/div>
<\/div>
\n

The EXP400-32X also supports Xsight Instruction Set Architecture (ISA) for users to define flexible packet processing rules,routing protocols, and network policies. The programmability is also an important underlying capability for many of the advanced features, including queue management, congestion control, and telemetry. The programmability handles newly-defined notification mechanisms, such as the Ultra Ethernet Transport (UET) protocol, packet trimming, and back-to-sender signaling.<\/p>\n<\/div><\/div><\/div>

<\/i><\/div>

Dynamic Load Balancing (DLB)<\/h3><\/div>
<\/div>
Optimized for interconnecting AI\/ML, storage, and compute clusters in data centers, the EXP400-32X supports congestion-aware routing, which comprises measuring and signaling congestion as well as load balancing across the network fabric. For a given fabric link, the EXP400-32X can measure flow rate, latency, and queue level. When congestion is detected, it can signal using Explicit Congestion Notification (ECN), Congestion Signaling (CSIG), or other customer-defined mechanisms. The EXP400-32X can handle flowlet-based load balancing and packet spraying across fabric links, as well as traditional flow-based approaches like ECMP.<\/div><\/div><\/div>
