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.

Fun Interactive Toy That Works as Advertised
Color: Basic, Color: Basic
I picked this up for my dog and have been pretty happy with it overall. The ball does exactly what it's supposed to do, rolling and bouncing around to keep my dog interested and active.
One thing I noticed right away is that it's a little larger than a standard tennis ball, which may be a consideration depending on the size of your dog. For my dog, the size wasn't an issue and actually made it easier to spot during play. The slightly larger size helped keep it from going under our sofa.
Recharging is simple. The ball opens easily to access the internal charging components, and I appreciate that the manufacturer included a keyed assembly system. The pieces only fit together the correct way, so there's no guessing when putting it back together after charging.
The build quality seems solid, and it has held up well so far. My dog enjoys chasing it around, although like most toys, it doesn't hold his attention forever. Still, it's a nice way to provide some extra stimulation and exercise. Overall, it's a well-designed interactive toy that functions as intended.

Awesome interactive dog toy.
Color: Basic, Color: Basic
This interactive dog toy is larger than the similar, smaller, older dog toys I used to buy. This ball has about a 1/2 inch layer of what feels like tough rubberized foam. The outer shell is stiff, but soft enough for the dogs to sink their teeth into and carry around. I have a small Boston and a medium mixed breed that both enjoyed playing with the toy. It was quick to charge and the battery seems to last a while. It will automatically turn off after some inactivity to save the battery, but will come back to life if it is nudged. Although, after a 30 minute period of inactivity, it will stay off an you have to unscrew the halves to manually turn it back on again. I wish it would just stay in the sleep phase so the dogs can revisit it the next day and trigger it back on again, instead of it turning off completely. Either way, the toy feels solid and is quality material. It has lasted longer than the multiple other smaller interactive balls I have purchased for my dogs in the past. It is good value for the money and I will purchase more so the dogs don't fight over this one. The included instructions are easy to follow, and it comes with a charging cable as well. I recommend.

Poor design and durability
Color: Basic
Product does not stay connected. Very easily comes apart when dog plays with it because he uses his mouth and paws and manages to twist the two halves apart. I want to return it but I do not see that this is an option.

Dog Approved! Not for heavy chewers.
Color: Basic
The puppy loved it. I wish I didn't have to open it to to turn it on/off or charge it but not a big deal. The case is a heavy foam with a fabric overlay so don't leave this toy unsupervised with your dog because if they get tempted to chew, they can certainly rip this thing apart and swallow chunks of it but really you shouldn't leave your dog unsupervised with any electric battery operated toy. The battery life is good, better than some other rechargeable toys we have for her. The motions aren't super awesome but they are enough to entertain the pup for a few when we want a break from getting bombarded to entertain her with regular old dog toys. This thing is cool and the size color, and quality were as expected.

Fun, durable, interactive dog toy
Color: Basic, Color: Basic
My dogs love this ball. It keeps them engaged with how it rolls, vibrates, and moves across the floor. Moves best on hard floors. The ball is very durable and they have not torn or ripped it at all. I really like that it is rechargeable so there are no batteries to replace. Had provided many hours of fun!
