Which port configurations are available on the E830-CQDA2 OCP 3.0 adapter?

By default, the adapter is configured as 2x100GbE. Using the Ethernet Port Configuration Tool and appropriate breakout cables, it can also be set to 1x200GbE on port 1, 4x50GbE, 2x50GbE, or 8x25GbE. These configurations enable tailoring the adapter to different link densities and bandwidth requirements per server.

What types of physical interfaces does the E830CQDA2OC3M provide?

The adapter offers two 100GbE QSFP28 ports and one 200GbE QSFP56 port and is designed for optical fiber media. It supports Ethernet media such as 100GBASE-CR4, 100GBASE-SR4, 100GBASE-LR4, 100GBASE-FR, 100GBASE-DR, 100GBASE-PSM4, and 200GBASE-CR4, 200GBASE-SR4, 200GBASE-LR4, and 200GBASE-FR4, enabling interoperability with common data center optics.

What host bus interface and form factor does this adapter use?

The Intel E830-CQDA2 OCP 3.0 adapter connects to the host via PCIe 5.0 x8 or PCIe 4.0 x16 and is delivered in an OCP NIC 3.0 Small Form Factor module. This combination supports deployment in OCP-compliant servers and leverages high-bandwidth PCIe interfaces aligned with current-generation platforms.

Can the E830-CQDA2 support lower-speed breakout connections such as 25GbE or 10GbE?

Yes, when used with suitable breakout cables, the adapter can provide up to 8 ports of 25GbE or 10GbE, with 4 ports per cage. It supports 25GbE SFP28 and 10GbE SFP+ breakout configurations, alongside 50GbE SFP56 options. This makes it suitable for mixed environments where some connections remain at lower speeds.
