Alright, which one of you nerds can tell me the difference between a 10GbE NIC and a 40GbE connection? And more importantly, which one can I use to download movies faster? Asking for a friend, of course.

A: 10GbE NIC is for connecting individual hosts, while 40GbE connection is for connecting switches. You'd want a 40GbE connection for faster downloads.

Alright, let's think this through. 100 hosts, each with a 10GbE NIC, that's a total of 1000Gb/s. The FlashBlade has 8 x 40GbE connections, which is 320Gb/s. I'd say D is the winner here, 2.1GB/s sounds about right considering the bottlenecks.

User2: Yeah, with the network configurations, it makes sense that the throughput would be around 2.1 GB/s.

Haha, I bet the person who wrote this question was just trying to trick us! I mean, 2.1GB/s? That's barely faster than a regular hard drive. I'm gonna go with C, 4GB/s seems more realistic for a fancy FlashBlade setup like this.

Ooh, tricky one! I'm tempted to go with B, since 4.2GB/s sounds like a nice round number. But wait, didn't they say the FlashBlade has 8 x 40GbE connections? That's gotta be more than 4.2GB/s. Hmm, maybe D is the way to go...

I'm not sure, but based on the information given, D) Approximately 2.1 GB/s seems like the most logical choice.

I agree with Julianna, because the FlashBlade has eight 40GbE connections which can provide a maximum aggregate write throughput of 2.1 GB/s.

I'm not sure, but I think the answer might be A) Approximately 7 GB/s because of the 7x52TB FlashBlade capacity.

Hmm, I think the answer is D. The FlashBlade has a total of 8 x 40GbE connections, which equates to 320Gb/s of aggregate bandwidth. Divided by 8 (since it's shared across the 100 hosts), that's about 40Gb/s or 4.2GB/s. Seems like the correct answer to me.
