Can you link those ones, please?
$13AUD each, buying 10 atta time - that fills your 305 with spares yeah?
Not sure when QNAP snuck this one out, but it's looking pretty good for the SOHO I think
8x 10/100/1000 ports
4x SFP+ 1000/10000
Plastic over metal chassis
12v power, 1.1 amp (12watts!)
Have you used them before?
Oh and I have 2 x csr309 and the csr305, so yes I will put a 10pk on the slow boat from China if you can vouch for them, I'm all out of spares.
I bought a couple from the same guy a few months ago to play with. Slightly different locking mech? to these but mine work a treat - 9.9 iperf windows gigs full duplex all day long with either Mellanox or Intel 520's. MFG date of 2010
Airfreighted I think. Only a couple of weeks from order to delivery last time around.
There is your issue....stop thinking and do This IS OCAU after all !
LOL, you make a strong point
Hmmmm, modern 25g fibre or old cheap dead-end 40gig gear?
Hmmm, let me look at it again tomorrow. They are $20 a throw cheaper than what I normally buy.
Yeah, despite the silicon & COVID issues the rush to jump to 25/50/100 in the DC has flooded the market with dirt cheap 10G fibre gear. Bonus, the fibres are cheaper than copper per m and will scale a shitload further.
We're currently getting generic LX 10G SFP's for $145 a piece. I'm assuming the SX modules would be cheaper again.
Yeah, $30 per from a vendor like fs.com or $13 for ebay specials.
VCSEL SX is dirt cheap these days.
But also a total pain if you're wanting to use the CAT6 runs already throughout the house.
sounds like you have pull strings already in place. makes installing easy.
Pre-terminated won't fit through holes in floors etc, plus some are bloody long so it would add up quite a bit.
I get that fibre often makes sense, but with CAT6 already in place that does 10Gb no problem, fibre to me is just a pain in the butt that I don't want to deal with.
You can still use them... as pull strings
Just jump straight to 25g. Copper no do that so you'll feel better.
Yeah, this is my problem. We built our house in 2009, and had it cabled with CAT6, so I have CAT6 between my rack (upstairs in a storeroom) and my office (downstairs), but they're at opposite ends of the house, so I reckon total cable length would be pushing 30m.
I -could- try to get 10GbE over it. It might work OK, but my switch has 4 x SFP+, but not 10GbE RJ45. I also have an x520 NIC already that I can use in my work PC, so it's really only the cabling that's the issue there.
Ny NAS, on the other hand, which is really the only other device I'd want on 10Gb, is also in the rack, and doesn't have either, so would have to be upgraded regardless.
Not really sure what to do. Kinda tempted to just get a couple of fibre runs put in from the rack to my office and be done with it. Upgrade the NAS to one I can whack an SFP+ NIC into, DAC cable it to the switch.
You could put a 10GbaseT transceiver in it.
Just ask yourself, "do you feel like shopping?"
"Well do you punk" <- ok maybe not that bit.
The further you go copper wise, the hotter the transceivers will run.
Yeah, I did briefly look at that, but they don't like much distance, do they? Would they go 30m?
Cheap test I guess, though I'd need one at each end I suppose.
EDIT: oh yeah, I can see some 80m ones at fs. Hmmm.
Yep they can, but how fast of a hit can your NAS handle?
If you are just R/W to the NAS via a single instance of Windows you should be trying to see if you can push past 300MB/s before moving past 2.5Gb as a solution.
Yeah, but my switch doesn't do 2.5Gb, so extra costs again to go there - plus it seems like a dead end to stick with CAT6 for that connection at the moment.
