Description
The HPE QR449A, identified as the X520-DA2, is a high-performance dual-port 10 Gigabit Ethernet (10GbE) network adapter designed specifically for server environments. It features two SFP+ (Small Form-factor Pluggable Plus) ports, which are versatile and can accommodate various types of transceivers (e.g., SR, LR) or Direct Attach Copper (DAC) cables, allowing for flexible connectivity options over short or long distances. This adapter connects to the server's motherboard via a PCI Express x8 (PCIe x8) interface. The PCIe x8 slot provides ample bandwidth to support the full 10Gb/s speed of both ports simultaneously, ensuring high throughput and low latency, which are critical for demanding server workloads such as virtualization, high-speed storage access (SAN/NAS), and data-intensive applications. The HPE X520-DA2 is engineered for reliability and efficiency in enterprise data centers. It supports advanced features that optimize network performance and manageability. Its robust design and high-speed capabilities make it an essential component for modern servers that require maximum network performance and scalability to handle increasing data demands.
