Sanity check for home network changes

Guest

The switch was purchased for setting up 10Gb fiber between my home's FreeNAS server and
three desktop computers.

Ok perhaps we should or have to talk about DHCP here in this case at first.
We are talking here about how many devices? 6 I count in total. So why not setting up
a static IP address for them all and finish this thread as solved!

Connect the pfSense box over one GBit/s line to the switch and the Switch to the NAS
over 10 GBit/s with one DAC cable and at last the three desktop PCs get a static IP address
and all is running fine then for you.
pfSense 192.168.1.1/24
Switch 192.168.1.2/24
NAS 192.168.1.3/24
PC1 192.168.1.4/24
PC2 192.168.1.5/24
PC3 192.168.1.6/24

All is done or if you really need the DHCP server urgent, for what ever you think it must be there
you can go with the DHCP Realy function and using them both on the pfSense box and on the Switch.

@johnpoz:

Looking forward to those details and benchmarks to drool over…

As promised, an iperf test…

Windows 7 desktop Samsung 840 Pro 256GB SSD with (Chelsio S310E-CR NIC) 50ft. OM3 LCLC MM fiber

iperf server and client connecting through the switch - Dell N2024 with two 10Gb SFP+ ports

FreeNAS box (intel X520-DA1) via Dell 1m SFP+ Copper Twinax

Not exactly drooling material I know, but we're working on it…

My desktop is gonna need a better NIC as the old Chelsio is PCI gen1 and a bit slow ;)

I have not purchased the second Dell switch yet, so I just have the one desktop connected at this point...

Realworld file transfer speed = 3.53 Gbps

I have a total of 11 or 12 other CAT6 cables attached to the switch that go all over the house
for various things like printers, TVs, Bluray players, wireless AP and lots of spare ethernet jacks.
I found no way to mark the thread solved, what am I missing?

Yes

the Switch to the NAS over 10 GBit/s with one DAC cable

Yes sir.

and at last the three desktop PCs get a static IP address and all is running fine then for you.

After the second switch is stacked, this will be the way it gets done.

All is done or if you really need the DHCP server urgent, for what ever you think it must be there
you can go with the DHCP Realy function and using them both on the pfSense box and on the Switch.

I'm perfectly happy to let pfSense do the DHCP, no need to complicate anything.

"713 Mbits/sec"

Dude I get better than that from a virtual machine to my physical machine.. Using cheap nics, and old I5 dell workstation, with n40L hp running esxi where the vm sits.... Switch is a sg300.. Not sure how running 10g make any sense here if your not even showing over a gig with iperf..

How exactly are you seeing 3.3Gbps real world if your iperf doesn't even show gig??

Seems your iperf is old as well, might want to try out 3..

Ok, so I don't know how to use iperf, old or new >:(

'How exactly are you seeing 3.3Gbps real world if your iperf doesn't even show gig??"

so why is iperf showing you crap then?

Windows file copy dialogs not known for their actuate transfer rates ;) But that is most likely the bottleneck of your disks… your running z2 right.. your in a 4+2 setup? So yeah that most likely max.. What are you writing it too on your pc? Maybe that is your limit to your SSD?

Now that you have 10gig your disks are too slow -- hehehee ;)

But yeah that is s nice fat number... Makes my 100+ look like crap ;) hehehe.. Then again mine is off simple drive pool running on a VM, with just gig cards..

If I had 10gig I would really be thinking of going SSD in some raid to be able to actually use that bandwidth...

I'll get to know iperf better, this is all new to me and I'm certain the TCP window size
(notice the different size between server and client) had something to do with the poor results.
My guess is once I learn more about iperf, the results will show somewhere north of 6Gb.
Right now, all I know is, I'm having fun AND it's much faster at transfering files AND those large
movie files (7 or 8GB) I watch on my iPad don't buffer anymore (that was a pleasant surprize). ;)
More to come.

johnpoz

I don't see how that could of been an issue, you plugging in your ipad? Its wifi even the latest pro model is only 866 PHY, so say 400mpbs over AC… So gig network would not of been a bottleneck..

BigDave

I finally learned to use iperf and posted a screen shot of the results from just now.
You may commence your drooling now ;D

Oh yeah this has me drooling!!! F__K that would be sweet ;)

I may have to do this – heheeheh!!!

If you want the 3.1.1 version, I compile it all the time for windows both 32 and 64 bit.. Since nobody else seem to be doing it that I could find.. You can grab it here http://files.budman.pw/
