Benefits and Features of PCI-Express Adapter

The X520-DA2 Intel Dual-Ports SFP+ 10 Gigabits Server Adapter is a high-performance network adapter card that can be installed in a server to provide it with two 10 Gigabit Ethernet (10 GbE) connections. It offers a range of benefits and features, including:

  • Dual SFP+ ports: The adapter has two SFP+ ports, which support the use of small form-factor pluggable (SFP+) transceivers, allowing for a variety of different types of optical fibers and cables to be used.
  • High-speed 10 GbE connectivity: The adapter provides high-speed 10 GbE connectivity, which is ideal for data centers, cloud computing, and other demanding network environments.
  • Advanced technologies: The adapter supports advanced technologies such as Virtual Machine Device Queues (VMDq) and Single Root I/O Virtualization (SR-IOV) to improve performance and reduce CPU utilization. Additionally, the adapter supports Intel's advanced technologies like Intel Data Direct I/O Technology and Intel Virtualization Technology for Connectivity.
  • Resiliency and High Availability: Dual-Ports provide redundancy, so that if one port fails, the other can take over, minimizing downtime. Additionally, the adapter supports link aggregation, also known as NIC teaming, which allows multiple ports to be grouped together to form a single, faster, and more resilient connection.
  • Intel Advanced Server Features: The adapter supports Intel Advanced Server Features such as Intel I/O Acceleration Technology (Intel I/OAT) and Intel Virtualization Technology for Connectivity (Intel VT-c) which helps to improve the performance, reliability and scalability of virtualized environments.
  • Power Management: The adapter supports Advanced Configuration and Power Interface (ACPI) which allows for the adapter to be power-managed by the operating system, reducing power consumption and heat generation.

Quality Components

The X520-DA2 Intel Dual-Ports SFP+ 10 Gigabits Server Adapter is a high-performance network adapter card that is built with quality components to ensure reliability and durability.

One of the key components of the adapter is the SFP+ transceiver, which is a small form-factor pluggable module that converts electrical signals to optical signals and vice versa. The SFP+ transceiver is a critical component that ensures the adapter can transmit data over optical fibers and cables. These SFP+ transceivers used in the adapter are compliant with industry standards and are of high quality to ensure maximum performance and compatibility with various network environments.

The adapter also uses high-quality capacitors and other components that help to ensure the stability and longevity of the adapter. Additionally, the adapter's PCB (printed circuit board) is designed to provide optimal signal integrity and minimize the effects of electromagnetic interference (EMI) to ensure consistent and reliable performance.
