Larch Networks 32X400 QSFP56-DD TOR/LEAF/SPINE SWITCH LN-4332Z4

LN-4332Z4 is a high port density switch with 32 x QSFP56-DD ports in a single 1RU and single packet forwarding engine, suitable for Datacenters that need unprecedented speed. With 32 QSFP56-DD 400Gpbs ports it is ideally suited for deployment at leaf/spine in datacenters, where high performance is the most important, or, with 12.8Tbps total performance -as ultra-powerful appliance. LN-4332Z4 is primarily packaged to meet the requirements of deployments that require smaller form factor and access to all network ports and management ports from the front side of the product. RSEM-W1-32 will be used to provide 32 x 400GbE +2 x 10GbE ports solution. In the interest of achieving the smallest possible form factor, minimum cost and the lowest system power consumption In order to be able to fit all access, uplink and data ports on the front side of a 1U system, all data plane connectivity to LN-4332Z4 is provided through QSFP56-DD sockets. Each QSFP56-DD socket can operate as a single 400GbE port. Main Ethernet access ports are QSFP56-DD sockets which support 400GBASE-SR8, 400GBASEFR8, 400GBASE-LR8, 400GBASE-ER8 and 400GBASE-DR4 physical layers. The total system contains a CPU subsystem with 16GB of DDR4 RAM and 64GB of M.2 SSD storage by the default setting. The CPU is connected to a set of central management processors that reside elsewhere in the system through an out of band control plane Ethernet connection.
