NVIDIA Mellanox® MCX354A-FCBT alternative ConnectX-3 NIC PCIe 3.0 x8 Dual Port 40GbE QSFP+ FDR IFB
PCIe x8 ConnectX-3 Pro FDR InfiniBand Dual-Port 40/56GbE FDR InfiniBand Adapter Card with Virtual Protocol Interconnect (VPI) supports InfiniBand and Ethernet connectivity with a hardware offload engine to the overlay network ("tunnelling"). This is useful in public and private cloud clustered databases, parallel processing, transactional services and high performance embedded I/O applications.
Embedded I/O applications will realize significant performance improvements, resulting in the most flexible interconnect solution that reduces completion time and cost per operation. ConnectX-3 Pro improves network performance by increasing available bandwidth while decreasing the associated transport load on the CPU especially in virtualized server environments.

Premium Quality Shelves That Look Amazing
Color: American Walnut - Satin Dark Tone, Number Of Shelves: Pack of 3, Size: 36 inch, Color: American Walnut - Satin Dark Tone, Number Of Shelves: Pack of 3, Size: 36 inch
For my Kitchen remodel, I’ve ordered several of these shelves, in different lengths, and I’ve been consistently impressed with the quality. I had never installed floating shelves before, but the process was surprisingly straightforward even when I customized my own corner setup.
The shelves are beautiful, made from real wood with exquisite grain patterns, and they arrive very well sanded and varnished. The installation instructions are clear and easy to follow, and the mounting bracket is sturdy with an excellent precision fit. Once installed, the shelves feel extremely solid and secure.
This company clearly takes pride in its products. Even the packaging is carefully and thoughtfully done. With some careful measuring, clamps, and a pocket hole jig, I was able to combine two different shelf sizes to create a custom corner shelf that turned out great.
I highly recommend these shelves and will definitely continue purchasing them as I add more to my home.

Clean Aesthetic, Limited Adjustment on Brackets
Color: Natural Pine - Satin Clear Coat Finish, Number Of Shelves: Pack of 2, Size: 16 inch
These shelves look really nice once installed—the natural wood finish gives a clean, high-end look that fits well with pretty much any space. Installation was straightforward and didn’t take much time, which I appreciated.
My only downside is the bracket design. I wish it had some kind of micro-adjustment option after drilling, because if your holes aren’t perfectly aligned the first time, it can be a bit frustrating to get everything level.
Overall though, still a solid product—sturdy, good quality, and definitely adds a nice aesthetic to the wall.

Finally, great shelves!
Color: Walnut - Warm Brown Woodgrain, Number Of Shelves: Pack of 4, Size: 30 inch
Having tried several shelves, this is by far the best product we have received. These shelves are real wood, well cut and prepared, with very easy installation and are quite stable. They look wonderful in the bedroom we purchased them for, and we like them so much that we have just order another set for another room. These shelves are well worth every penny, and came with a beautiful thank you card from the small business from whom we purchased them...we thank them!
