What interface and form factor does the Dell 540-BDEE support?

The 540-BDEE uses PCI Express interface in low-profile form factor, compatible with Dell PowerEdge R640 and similar 1U/2U servers. PCIe 3.0 x16 provides full bandwidth for dual 100G ports without bottlenecks in high-density rack environments.

What transceivers are required for 100GbE operation?

Requires QSFP28 transceivers supporting 100GBASE-SR4, LR4, or CWDM4. Backward compatible with QSFP+ via adapters. Supports direct attach copper (DAC) cables up to 5m and multimode fiber for short-reach data center deployments.

Does it support RDMA and storage protocols?

Yes, Broadcom 57508 enables RoCEv2 for low-latency storage fabrics, plus full iSCSI and NFS hardware offloads. Ideal for NVMe-oF deployments requiring sub-microsecond latency between servers and all-flash arrays.

What is the power consumption and thermal design?

Typical power draw around 15-20W under full load with dual 100G traffic. Low-profile bracket with optimized airflow supports dense server cooling without thermal throttling in high-performance computing environments.

Is it compatible with virtualization platforms?

Full SR-IOV and VMQ support for VMware ESXi, Hyper-V, and KVM. Enables network virtualization with up to 64 virtual functions per port, reducing hypervisor CPU overhead in consolidated server environments.

What cable types work with QSFP28 ports?

Supports QSFP28 DAC up to 5m, AOC up to 100m, and multimode fiber with MPO connectors. Breakout cables enable 4x25G connectivity to downstream 25G infrastructure while maintaining full 100G uplink capability.
