For L3 features, we suggest to replace to B1 version. • HQ will provide free CPU daughter board to upgrade the A1 devices to B1 in the future* * CPU board replacement will go though RMA process

  11. Hardware Overview – Cooling System • Optimized cooling system to fit the heat dissipation design of data center: • Customers can choose desired airflow by using different power and fan module which support • Front-to-Back • Back-to-Front Cold Aisle Hot Aisle Hot Aisle Cold Aisle P.S Different airflow modules cannot be mixed.

  12. Hardware Overview– Cooling System Maintain the same airflow direction in a rack to avoid unexpected system crash and extend the lifespan Provide the flexibility to turn the switch front panel to the same side of server ports for better cable management • Keep the same side for DXS-3600’s front panel with server ports to • reduce cable length • simplify cable management.

  25. Technology Brief – Data Center Bridging(DCB) • IEEE 802.1Qbb Priority-based Flow Control (PFC) • A flow control mechanism that can be controlled independently for each CoS • The goal is to ensure zero loss (lossless) under congestion in DCB network q0 q1 q2 q3 Congestion q4 q5 q6 STOP q7 Pause Source Port 1 Destination Port 1 q0 q1 q2 Remain transmitting q3 q4 Queue 4 congested q5 Pause q6 q7 Destination Port 1 Source Port 1

  26. Technology Brief – Data Center Bridging(DCB) • IEEE 802.1Qaz Enhanced Transmission Selection (ETS) • Anenhancement of transmission selection to support allocation of bandwidth amongst traffic classes • When a traffic doesn’t use allocated bandwidth, ETS allow other traffic class to use the available bandwidth q0 q1 q2 q3 q4 q5 SP IPC grouping policing q6 SAN – 50% q7 WRR LAN – 50% • Priority Group ID (PGID) = 15A special value indicates the priority is not managed by ETS; this is used for SP • PGID 8 to 14 are not used Inter-Process Communication (IPC) SAN LAN

  27. Technology Brief – Data Center Bridging(DCB) • IEEE 802.1Qau Congestion Notification (QCN) • Enable switch to signal congestion information to end station capable of transmission rate limiting to avoid frame loss • QCN works across a single L2 domain Switch A Switch C Host B Send CNM to RP switch to reduce the transmission Host C 2 4 Switch B 1 Monitoring output queue size 3 Send CNM to end station to reduce the transmission CP RP Host A CP: Congestion Point RP: Reaction Point CNM: Congestion Notification Message

  28. Technology Brief – DCBX • Data Center Bridging Exchange Protocol (DCBX) • DCBX allows auto exchange of Ethernet Parameters and Discovery Function between switches and end points • Goals of DCBX: • Discovery of DCB capability in a peer • DBC feature misconfiguration detection • Peer configuration of DCB features Data Center Ethernet Links DCBX Legacy Ethernet Links Legacy Ethernet Network Data Center Ethernet Cloud

  29. Technology Brief – Forwarding Method • Cut Through Switching • DXS-3600 series examines the first 560 bytes to make the forwarding decision in cut through mode to shorten the forwarding latency • Whereas a store-and-forward switch makes a forwarding decision on a data packet after it has received the whole frame and checked its integrity Evaluating 560 bytes and then forward the packet Receiving whole packet and then forward it
