Its ports run at 10 or 25 Gb Ethernet (and lower speeds) with SR, LR or copper connections, and it has 4 GB of onboard memory and PTP time sync. Listed latency is as low as 629 ns for 64 byte raw frames and about 850 ns for small TCP packets, with up to 128 IP and 64 MAC filter rules per port.\u003c\/p\u003e\n\n\u003cp\u003eKey Features\u003cbr\u003e\n- 2 x 10\/25G SFP28 ports\u003cbr\u003e\n- Ultra low latency\u003cbr\u003e\n- 4 GB onboard memory\u003cbr\u003e\n- PTP time sync\u003cbr\u003e\n- PCIe 3.0 x8\u003cbr\u003e\n- Low profile card\u003c\/p\u003e\n\n\u003cp\u003eProduct Information\u003cbr\u003e\nBrand: Cisco\u003cbr\u003e\nManufacturer: Cisco Systems\u003cbr\u003e\nProduct Line: Cisco Nexus\u003cbr\u003e\nModel: X25 SmartNIC (K3P-S)\u003cbr\u003e\nProduct Type: Expansion module\u003cbr\u003e\nPackaged Quantity: 1\u003cbr\u003e\nColor Category: Black\u003c\/p\u003e\n\n\u003cp\u003eNetwork and Communication\u003cbr\u003e\nConnectivity Technology: Wired\u003cbr\u003e\nData Link Protocols: 10 Gigabit Ethernet, 25 Gigabit Ethernet, Fast Ethernet, Gigabit Ethernet\u003cbr\u003e\nCable Type: Ethernet 25GBase-CR, Ethernet 25GBase-LR, Ethernet 25GBase-SR\u003cbr\u003e\nPerformance: Latency (14-byte packets) TCP: 850 ns, Latency (14-byte packets) UDP: 810 ns, Latency (256-byte packets) raw frames with preloaded TX buffer: 665 ns, Latency (256-byte packets) TCP: 1.1 µs, Latency (256-byte packets) UDP: 1.1 µs, Latency (256-byte packets): 897 ns, Latency (64-byte packets) raw frames with preloaded TX buffer: 629 ns, Latency (64-byte packets) raw frames: 696 ns, Timestamp resolution: 4 ns\u003cbr\u003e\nCapacity: IP rules per port: 128, MAC rules per port: 64\u003cbr\u003e\nFeatures: Precision Time Protocol (PTP)\u003c\/p\u003e\n\n\u003cp\u003eConnectivity\u003cbr\u003e\nPCI Specification Revision: PCIe 3.0\u003cbr\u003e\nPort Quantity: 2\u003cbr\u003e\nInterface Provided: 2 x 25Gb Ethernet - SFP+\/SFP28\u003cbr\u003e\nNetwork \u0026amp; Adapter Ports: SFP+\/SFP28\u003cbr\u003e\nHost Interface: PCI Express 3.0 x8\u003c\/p\u003e\n\n\u003cp\u003eMemory and Processor\u003cbr\u003e\nRAM Installed: 4 GB\u003c\/p\u003e\n\n\u003cp\u003ePhysical Characteristics\u003cbr\u003e\nForm Factor: Plug-In Card\u003cbr\u003e\nLow Profile: Low profile\u003c\/p\u003e\n\n\u003cp\u003eDimensions and Weight\u003cbr\u003e\nHeight: 2.7 inch\u003cbr\u003e\nDepth: 4.6 inch\u003c\/p\u003e\n\n\u003cp\u003eCertifications and Listing\u003cbr\u003e\nCompliant Standards: IEEE 1588\u003c\/p\u003e\n\n\u003cp\u003eNot sure this adapter or module fits your system?
