Product Identity

The Winait QSFP28 E810-CQDA2 is a dual-port 100GbE network adapter built on the Intel 810 controller. It connects servers or workstations to 100 Gigabit Ethernet fabrics through two QSFP28 cages. The card is new and was first listed by the manufacturer in 2023.

Fit and Limits

This adapter suits environments that need two 100GbE links from a single PCIe slot. It does not serve builds that require only one 100GbE connection, or that target lower-speed fabrics. Buyers needing fibre-channel, InfiniBand or other protocols should select a different card.

Deciding Specification

The card provides two QSFP28 ports each rated at 100GB maximum data rate. Confirm that your switch, cabling and driver stack support this exact speed and connector type before purchase.
