Cisco Nexus X100 SmartNIC (K3P-Q) - Network Adapter - PCIe 3.0 X8 Low Profile - QSFP28/QSFP+ X 2 - For UCS C240 M5, C240 M5L, SmartPlay Select C240 M5, SmartPlay Select C240 M5CL - NXN-K3P-8X-9GB

• Cut-through receive
  This mechanism allows software to process packet fragments as they arrive from the wire, while packet tails are still in flight. This is especially effective for slow line speeds (for example, 1GbE). The Cisco Nexus X100 SmartNIC K3P-Q software API puts users well ahead of traditional store-and-forward NIC designs to make better decisions, faster.
• ExaSOCK TCP/IP acceleration
  Unmodified socket applications can benefit from the speed and power of the Cisco Nexus X100 SmartNIC K3P-Q using ExaSOCK. ExaSOCK is an in-place TCP/IP socket acceleration system.
• Preloaded packet transmit
  The Cisco Nexus X100 SmartNIC K3P-Q allows users to preload transmit frames, saving 60 ns from the transmit path. The X100 SmartNIC K3P-Q features enlarged packet transmit buffers allowing many more frames to be preloaded, leading to more versatile transmission choices.
• High-resolution timestamps
  The Cisco Nexus X100 SmartNIC K3P-Q also features out of the box support for IEEE1588 (PTP) and high-speed capture to disk using free and open-source Exact-Capture software.

The Cisco Nexus X100 SmartNIC K3P-Q is a high-density NIC, specifically optimized for low latency operation. Features 2x QSFP28 ports that can be deployed in a high-density 8-channel configuration and software trigger-to-response latencies as low as 596 ns. Users will find that this drop-in replacement NIC accelerates tick-to-trade performance to previously unachievable speeds, increasing the efficacy and profitability of software-based trading systems.
