NVIDIA Mellanox® MCX354A-QCBT 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.

Beautiful Watch, but . . .
Color: 6617:Blue Dial and Gold Silver Strap
I’m updating this review and lowering to one star. Would be zero if possible. Another 2 weeks of owning this junk watch. I’m now having to wind it daily and reset the time. The only reliable feature is that it’s going to stop in the middle of each night. Piece of junk. Don’t buy. This is a beautiful watch but not very reliable timepiece. This is a self winding watch which requires you to wear it 24/7 in order to keep working. i wanted a nice watch which looked good, kept good time, was affordable and a bit nicer. I work a standard M-F, 8-5:00 workweek. I wear my watch daily for work and on RARE occasions after work or weekends if going out. My watch typically sits on the bedroom dresser after work hours and weekends. I've had this watch about 3 weeks now and have had to wind it and reset the watch three times during the time I've had it. If you are not wearing it for more than a day the watch runs down and and comes to a complete stop. You then need to manually wind and reset. This was a concern after reading other reviews. I tried to find the same watch with a quartz movement and battery for this very reason. But this particular watch only comes in a mechanical self winding version. They have ONE other model with a similar look that has a quartz movement with battery. That watch is made in China; this one is made in the USA. This is another factor that convinced me try the self winding mechanical version. Big mistake, I should have looked at other brands and manufacturers. It turns out this was a regrettable impulse buy based on looks but not practical. It is not a reliable timepiece. Lets face it a watch's function is to reliably tell the correct time; if you're not willing to manually wind it and reset the time and dates every Monday morning this is not a practical timepiece. I would NOT buy this again for this reason.

Beautiful but the smallest size
Color: all gold, Color: all gold
Really a beautiful watch but I give it 4 stars because it really doesn't have the 45 mm diameters that were specified in the size, it has the same 41 mm as the rest of the models.

This watch is soooo nice
Color: all gold
I bought this as a Christmas present for me. It is so nice... OLEVS makes the nicest watches. Their stuff always looks like a million bucks. I frequent their stuff—lots of compliments. I am so pleased to have self-winding watches. I had a Rolex Daytona. It was self-winding.

High quality and great presentation
Color: 2 Pack (M+L)
I got the 2 pack in black. The measurements listed are accurate. I measured my gift before ordering and loved having 2 sizes to choose which made for the better final look. The black is a true black, not light or faded, and the texture and thickness of the material made it look so high quality - way nicer than flimsy drugstore gift bags. Love that the handles are ribbons instead of the cheap stiff paper or rope-like ones. The included tissue paper was a perfect finishing touch and made for an impressive finished look.

Very nice but not wide
Color: Large Black
The quality is nice. The height is great but the width is not great. Good for small clothing like a T-shirt or small gifts.
