Buying the compatible transceivers and relabeling them as extreme networks. ;)I don't get it? for?

AHHHH!!! (ROLF) Would make some serious coin! LOL :DBuying the compatible transceivers and relabeling them as extreme networks.

In re-reading through the rest of this, I'm thinking that your old X7 may just be out of steam. You might try linking the two servers directly together and configuring jumbo on that, just to see... if it's merely out of oomph to handle packet-per-second, that'll increase speeds dramatically, but if you're out of some sort of internal bandwidth, it won't make a big diff. Basically a lot of the old gear is never likely to consistently get close to 10G, especially when you consider all the NAS protocol stuff sitting on top. What I'm saying is that if you can only get 5Gbps with iperf, you're going to get a lot less when you factor in the NAS protocol, ZFS, etc.
I tried to explain that exact same point but at the end of the day I can't order anything without my manager signing off on the requisition form. I have found that most of the time, not always, but most, the person managing the datacenter team is the least qualified to be working in a datacenter.Printing up tiny labels that read "Extreme Networks", of course. :)
The point is that in general there's only a few companies on the planet that make the actual optics, and often/usually you can get optics that are electronically and physically identical, because Extreme Networks buys theirs from (guessing here) Finisar. So it's extremely common for large networking organizations to buy an SFP programmer and use generic optics. Your current Internet traffic is, virtually guaranteed, going over at least some generic optics right now.
I find it simpler and cheaper just to buy used optics and test them. For example, the Dell gear we use here (actually a Force10 Networks design), I was finding the optics on eBay for about $20-$25 each, and at that price, you can't even get the generic optics new for that price, much less the cost of the programmer.
Usually there'll be some smart guys out there selling "private label" versions of the SFP's which are just preprogrammed to look legit. You could take a laser printer and make yourself some legit-looking teeny SFP labels and the only way an Extreme Networks engineer would be likely to notice would be if they started validating serial numbers. :)
True, but I've seen other members pointing out 8 and 9Gb/s.you're going to get a lot less when you factor in the NAS protocol, ZFS, etc.
What is this "auto scale" that you are referring to?I found that the auto scale feature was a waste of time
Oh! I hear that! Sometimes people can just be abrasive!I need to knock some rough edges of my understanding and notes before I commit them to public scrutiny.
You'll find this is the case most the time no matter where you go. Sometimes you'll find someone that believes and trust in their employees to make good decisions that are good for the company, but it's not often.I tried to explain that exact same point but at the end of the day I can't order anything without my manager signing off on the requisition form.

I don't know... I'll have to do more testing. I'll have to connect directly to my desktop and see what I can pull from it.
