Description
Product Overview
Intel E810-2CQDA2 is a high-speed dual-port network adapter designed for data centers and enterprise environments. This adapter is based on the PCI Express 4.0 interface, which delivers fast data transfer rates for both networking and storage. It supports QSFP28 connectivity and provides a range of features to optimize network performance and reduce latency.
Dual Ports
The Intel E810-2CQDA2 adapter is equipped with two QSFP28 ports, each capable of delivering up to 100 Gbps of data transfer rate. This dual-port design allows for high-speed data transfer between servers and switches, making it ideal for use in high-performance computing (HPC) environments, cloud computing, and other applications that require high bandwidth.
PCI Express 4.0 Interface
The E810-2CQDA2 adapter is based on the PCI Express 4.0 interface, which delivers up to twice the bandwidth of the previous generation PCIe 3.0 interface. This allows for faster data transfer rates and reduced latency, improving overall system performance. The adapter is compatible with both PCIe 4.0 and PCIe 3.0 slots, making it easy to integrate into existing systems.
QSFP28 Connectivity
The E810-2CQDA2 adapter supports QSFP28 connectivity, which is a high-speed data transmission standard that can transfer up to 100 Gbps over a single cable. This allows for fast and efficient communication between servers and switches, reducing latency and improving overall system performance. The adapter is also backward compatible with QSFP+ and SFP+ transceivers, providing flexibility for different network configurations.
Network Optimization Features
The Intel E810-2CQDA2 adapter provides a range of features to optimize network performance and reduce latency. These include support for TCP/IP Offload Engine (TOE), Remote Direct Memory Access (RDMA), and Message Signaled Interrupts Extended (MSI-X). These features help to reduce the load on the CPU and improve network efficiency, resulting in faster data transfer rates and improved system performance.
TOE
TOE is a network acceleration technology that offloads the processing of TCP/IP protocols from the CPU to the network adapter. This reduces the load on the CPU and improves network efficiency, resulting in faster data transfer rates and reduced latency. The Intel E810-2CQDA2 adapter supports TOE, which can significantly improve network performance in high-traffic environments.
RDMA
RDMA is a network acceleration technology that enables direct data transfers between the memory of one computer and another without involving the CPU. This reduces the load on the CPU and improves network efficiency, resulting in faster data transfer rates and reduced latency. The Intel E810-2CQDA2 adapter supports RDMA, which can be beneficial in HPC and other data-intensive environments.
MSI-X
MSI-X is an advanced interrupt-handling mechanism that allows network adapters to allocate more interrupts to individual cores, reducing latency and improving performance. The Intel E810-2CQDA2 adapter supports MSI-X, which can help to improve overall system performance in multi-core environments.
In summary, the Intel E810-2CQDA2 dual-port network adapter is designed to provide high-speed, low-latency connectivity in data centers and enterprise environments. It supports QSFP28 connectivity and provides a range of features to optimize network performance and reduce latency, including TOE, RDMA, and MSI-X. The adapter is based on the PCI Express 4.0 interface, which delivers fast data transfer rates for both networking and storage. With its high-speed dual-port design, the E810-2CQDA2 adapter is an ideal solution for HPC, cloud computing, and other applications that require high bandwidth and low latency.
