Pros & Cons
Pros
- ✓ Genuine Intel 82576 controller, not a rebadge; behaves like an E1G42ET to drivers
- ✓ Dual RJ45 gigabit ports on one PCIe x4 card for routing, VLANs, or link aggregation
- ✓ Runs up to 100m over Cat-5 copper, so no media converters for long in-wall drops
- ✓ Ships with both standard and low-profile brackets for 1U/2U and SFF chassis
- ✓ 3-year warranty plus 30-day free returns and lifetime tech support from 10Gtek
Cons
- ✗ No VMware ESXi 7.0 or newer support, ruling out current vSphere hosts
- ✗ No hot-swap support; the host must be powered down to install or remove the card
- ✗ Gigabit-only at 1.25GbE per port, so it will not feed 2.5G or 10G uplinks
- ✗ Needs a free PCIe x4 slot at 2.5 GT/s, a tight fit in slot-starved retro boards
