Summit X770 Series - 1

DATA SHEET Summit X770 Series BENEFITS HIGHLIGHTS The Summit X770 series switches are high-density, purpose-built top-of-rack switches designed to support emerging 10 Gigabit Ethernet and 40 Gigabit Ethernetenabled servers in enterprise and cloud data centers. Summit X770 helps optimize new server deployments with its 40 GbE ports – each can be used natively as Overview Summit X770 provides high density for 40 Gigabit Ethernet and 10 Gigabit Ethernet switching in a small 1RU form factor. uplinks to BlackDiamond X8 chassis or With its versatile design, the Summit X770 series provides high density Layer 2/3 other Summit X770 acting as spines – and switching with low latency cut-through switching, and IPv4 and IPv6 unicast and each 40GbE port can connect directly multicast routing to enable enterprise aggregation and core backbone deployment to servers using 40GbE speeds or by in AC-powered and DC-powered environments. breaking down into 10GbE connections acting as the leaf. Summit X770 series simplifies network operation with the ExtremeXOS modular operating system (OS), which is used among all Extreme Networks Summit and The Summit X770 can be used as a spine BlackDiamond Ethernet switches. The high availability ExtremeXOS operating or a leaf in fat tree topologies for servers system provides simplicity and ease of operation through the use of one OS PORTS • 32 x 40GBase-X QSFP+ • 1 RJ-45 Serial Port • 1 RJ45 Ethernet Management Port • 1 USB Port (rear) • 2 Mini BNC Ports (rear) 1588 output 40 GIGABIT ETHERNET & 10 GIGABIT ETHERNET PORTS The Summit X770 model provides 32 x 40 GbE QSFP+ ports which can accept QSFP+ passive and active cables, as well as QSFP+ transceivers. 40 GbE ports can be configured as a 40 GbE port or as four 10 GbE ports. The 10 GbE port mode can be supported by a 40GBASE-SR4 QSFP+ transceiver and fan-out optical cables, and is compatible with the 10GBASE-SR optical interface for distances up to 100 meters. 24 of the 32 QSFP+ ports can be broken into 4 ports of 10GbE. The remaining 8 ports of QSFP+ can also be converted into a single port of 10GbE giving a maximum of 104 ports of 10GbE connections in a 1 RU device. The Summit X770 is capable of Layer 2 and Layer 3 forwarding at up to 1904 million packets per second forwarding rate. HIGH-SPEED STACKING Summit X770 supports three different types of stacking: SummitStack-320, SummitStack-160, and SummitStack-V. SummitStack-320 provides high speed stacking running at 320 Gbps through the SummitStack-320 technology. SummitStack-320 can be enabled on four 40 Gigabit Ethernet QSFP+ ports as stacking interfaces. SummitStack-160 provides high-speed stacking running at 160 Gbps through the SummitStack-160 technology. SummitStack-160 can be enabled on two 40 Gigabit Ethernet QSFP+ ports as stacking interfaces. SummitStack-V provides high-speed stacking running at 40 Gbps through the SummitStack-V technology. SummitStack-V can be enabled on two 40 Gigabit Ethernet QSFP+ ports configured as 10GbE stacking interfaces. Summit X770 – Data Sheet

Figure 1: Top of Rack Switch for Servers in the Enterprise Data Center Modular Operating System for Non-Stop Operation LOADABLE SOFTWARE MODULES Bidirectional Forwarding Detection (BFD) is a hello protocol that provides the rapid detection of failures in the forwarding path and helps the separation of control plane connectivity from forwarding plane connectivity. By having multiple control plane protocols like OSPF or MPLS rely on BFD to detect forwarding The modular design of the ExtremeXOS OS allows the adding plane connectivity failures, network operators can benefit from or upgrading of...
