This article covers Cryfokt 10G 25G ネットワーク カード.

Overview

The Cryfokt 10G/25G Network Card is a dual-port PCIe x8 Ethernet adapter based on the Mellanox ConnectX-4 chip. It supports both 10Gbps and 25Gbps speeds, designed for data centers and high-performance computing (HPC) environments. With Remote Direct Memory Access (RDMA) and hardware acceleration, it reduces CPU overhead and delivers ultra-low latency. Compatible with Windows, Linux, and VMware, it integrates seamlessly into virtualized and cloud infrastructures.

Key Features

Dual SFP28 ports: Supports 10G and 25G speeds, allowing smooth migration from existing 10G infrastructure. Provides high throughput for bandwidth-intensive applications. PCIe x8 interface: Leverages PCIe 3.0 x8 bandwidth to handle dual-port 25G traffic. Easily installs into server or workstation PCIe slots. RDMA support: Enables direct memory-to-memory data transfer without CPU involvement, drastically reducing latency. Ideal for storage virtualization and latency-sensitive workloads like financial trading. Hardware acceleration: Offloads iSCSI, IPsec, jumbo frames, and IPv4/IPv6 routing to hardware, freeing CPU resources for applications. * Broad OS compatibility: Supports Windows, Linux, VMware, and overlay protocols like VXLAN, Geneve, and NVGRE for modern network virtualization.

Connectivity & Compatibility

This card requires a PCIe x8 or x16 slot (x4 slots may limit bandwidth). Use SFP28 transceivers (sold separately) for 10G or 25G fiber or DAC connections. RDMA functionality requires compatible switches and storage devices. PXE boot is supported via BIOS/UEFI for network-based OS deployment.

Product Info

Released around 2024, available on . Pricing varies but offers good value compared to similar 10G/25G adapters. Warranty typically 1 year from the seller. Includes only the card; transceivers and cables are not included.

Best Use Cases

Data center administrators: Ideal for upgrading from 10G to 25G infrastructure, improving storage and HPC cluster performance with RDMA. HPC users: Suitable for scientific computing and simulations requiring low latency and high bandwidth. * Virtualization builders: Perfect for multi-tenant environments using VMware or KVM, leveraging SR-IOV and overlay networks for security and performance consistency.
