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.
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.
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 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 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 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.

About Refurbished Products
A network adapter also called a network interface card is a plug-in card that serves to allow computers to both transmit and receive data on a local network. It is a component of a computer's internal hardware that facilitates communication over a network.
In a more current context, network adapters will refer to an Ethernet adapter where the Ethernet circuitry is built into motherboards of the latest desktops and laptop computers. Other times, a network adapter may also refer to a wireless (Wi-Fi) adapter.
In all instances, the adapter allows a computer to connect with another computer, a server, or other networking devices through a LAN connection. The use of a network adapter is not limited to wired connections as it is used for wireless networks. The adapters for wired networks come with an RJ-45 port that may use either the twisted or untwisted pair cables for network connectivity. For the wireless adapters, the network connection is facilitated through a built-in antenna or an externally connected antenna. Both the wired and wireless network adapters support the popular LAN protocols including TCP/IP. We have 1-port, 2-port, 4-port, 6-port, 8-port, and 16-port options that support speeds of 10, 25, 40, or even 100 Gigabits.
The plug-in network interface cards (NICs) are normally used in high-performance machines especially if a faster Ethernet standard is relatively new and available but is yet to become mainstream. In fact, the major difference between network adapters lies in the network protocol it supports.
We have the different types of network adapters necessary for building computer-to-computer networks that don't have a switch or hub. All the network adapters are fairly inexpensive and readily adaptable to different applications within a network. Some of the common types available are:
Network adapters common types
- Desktop Network Interface Card: This adapter is usually connected to a PCI or PCIe slot, whichever is available on the motherboard of your desktop computer. You will need to open your computer's case and it, therefore, presents the most difficult installation method. The PCIe slot is generally found in new computers.
- PC Card or PCMCIA Card: PCMCIA is the abbreviation for Personal Computer Memory Card International Association. The name has undergone changes over time to be referred to as a PC Card or ExpressCard. For dimensions, the PC card is almost similar in size to a credit card but is significantly thicker. The PC card is connected to a PC or PCMCIA card slot in your desktop computer or laptop computer.
- USB adapter: This network adapter is typically a small device, similar to a thumb drive, with a USB interface. Installation is easy and straightforward since it is plugged into the USB port of your desktop or laptop computer or other network devices that have a USB port.
- Wireless game adapters also referred to as media adapters, are connected to older game consoles and home entertainment devices so as to act as a bridge to Wi-Fi capability. They help expand functionality on these entertainment devices through connections to the internet.
