As someone on ausnog pointed out previously, even new patch cables should be cleaned prior to use.<br>
<br>
(He included pictures, but my google skills are failing to find the thread)<br>

So, yeah, Layer1 first, apply your fibre cleaning tools to the fibres,<br>
SFPs, patch leads etc.<br>
<br>
10gig gets very very twitchy if the cables and SFPs aren't cleaned<br>
properly...<br>
<br>
Better still, swap out all the patch leads for brand new ones and see<br>
what happens...<br>

There is no trial and error. Start at Layer 1, and work up the<br>
stack.<br>
<br>
Correct setup and good logging should resolve it.<br>
<br>
There are lots of potential issues. You can cut some of them down<br>
immediately by selecting hardware on the hypervisor supplier's HCL -<br>
they should have good drivers for the 10Gbps NICs at that point.<br>
<br>
Speed/duplex, frame size, etc, all need to be consistent across the<br>
entire environment. Get wireshark or an equivalent involved (using a<br>
mirror port if necessary).<br>
<br>
If your hardware and software are all under full support, involve<br>
your vendors in the issue.<br>

Hi Noggers<br>
<br>
We’re having “fun” with 10GB NICS, Switches and SFPs.<br>
<br>
We can’t work out which is causing drop out, packets.. we are<br>
somewhat certain packets are vanishing into the Ether..<br>
<br>
We don’t know which is causing what.<br>
<br>
I’m not after troubleshooting, I am curious what people’s view<br>
on this.<br>
<br>
Do you buy 1 Vendor for all your 10GBs, A-Z, is there some hidden<br>
rule about mixing vendors, is this all trial and error (and very<br>
expensive at best)?<br>
<br>
Any recommendations on set ups? Preferred Vendors, Vender to<br>
avoid like the plague.<br>
<br>
We’re talking Servers to Switch kind of thing. Not SANs etc.<br>
Good ol’ HyperVisor to the switch.<br>
<br>
Thanks<br>
<br>
Regards,<br>
