Summit X770 series switches are high density, low latency 40 Gigabit Ethernet Top-of-Rack switches.
The Summit X770 series switches are purpose-built top-of-rack switches designed to support 10 Gigabit Ethernet-enabled servers and emerging 40 Gigabit Ethernet-enabled servers in enterprise and cloud data centers. Summit X770 helps optimize new server deployments by supporting 40GbE ports natively or using breakout cables and/or fiber to support 10GbE ports to start the transition to the new virtualized environment.
The Summit X770 switch supports up to 104 ports of 10GbE in one system and 816 ports of 10GbE in a stacked system using high-speed SummitStack. The Summit X770 model supports 3 different stacking methods: SummitStack-320, SummitStack-160, and SummitStack-V. SummitStack-320 uses 4 ports of QSFP+ 40GbE providing 320 Gbps of stacking bandwidth in a stacked ring architecture full duplex. SummitStack-160 uses 2 ports of QSFP+ 40GbE resulting in 160 Gbps of stacking bandwidth. And SummitStack-V uses 2 ports of 10GbE, created from converting 2 ports of QSFP+ 40GbE into 2 ports of 10GbE connections, creating 40 Gbps of stacking bandwidth.
The Summit X770 series provides high density Layer 2/3 switching with MPLS and with low latency cut-through switching, and IPv4 and IPv6 unicast and multicast routing to enable enterprise aggregation and core backbone deployment in AC-powered and DC-powered environments as well as Front-to-Back and Back-to-Front airflow models.
The Summit X770 provides store-and-forward as well as cut-through forwarding options. The latency of 64-byte packets using cut-through forwarding is less than 600 nanoseconds.
Summit X770 series include the ExtremeXOS modular operating system. The high availability ExtremeXOS operating system provides simplicity and ease of operation through the use of one OS everywhere in
