Any cost efficient methods to get greater than 1Gbps transfers

[Darren Myers]

It will not gives a 2gb speed for a single client, that's already understood. But it will not always balance 2 client by utilizing both links , it does balance sometime wheever it wants, mostly not when needed. You are right i don't want lacp. It is setup as lacp but i'll change it, as soon as i can come up but better configuration.

I am trying to understand if 2 subnets can exist on the same switch(both 1gb nics) ? Does it need vlan separation to work ?

I would use a separate VLAN for a different IP range or subnet, unless youre not using DHCP then by all means dont worry about VLANs.

Thanks.
Do you know how to check my X9SCM bios version from freenas , without going bios menu ?

I start accessing my freenas by ip like you do you 10GB subnets, but some time I got this message : " These files might be harmful to your computer..." , but when I access the same place by \\freenas instead no message about locking files ?! Are you familiar with this Issue ?

 

[Darren Myers]

Mhmmm I think I had it once but I don't really pay attention to any prompts unless it's it can't be reached; I think I've run into it a few times but 90% of the time it's applications grabbing the data from FreeNAS.

I sometimes got the error when copying and pasting.

What kind of switch you are using for you 1Gb clients ?

I am using 2 dlink websmart switches with 4 fiber uplinks (switch to switch) http://www.amazon.com/dp/B003L62T1I/?tag=ozlp-20

Thanks for you fast response. I am on a market for a 48 Port Gb switch and tying to find recommendations.

It lacks some features i would like....i would of liked a switch with built in PoE, i like netgear and cisco if i have a choice in the matter or a budget, my dlinks are there simply to get me by, when one or both die they will be replaced by something more preferable

I am between Cisco and Dell . What you think about dell ? As far as PoE I rather not have it. It's one of those things that I don't understand and naturally scared of it. I have few cameras that will be very happy to get PoE , but I am scared of the risks, like when the switch goes haywire ( firmware bug, bad component, or etc) and start sending power where it shouldn't in the amounts it shouldn't and basically fry all nics on the network connected to it.

 

[Darren Myers]

Dell makes some nice switches, i looked at there 10Gb stuff when i was pricing out 10Gb switches, but saw most of them going for 1200-1600$. As per your concern its understandable but doubtful it would actually happen, but PoE injectors are of course a good option too if you only have a few devices.

I am thinking 48 Gb ports with 4x10Gb up links will do me fine for now. For the PoE it will not happened often of course , but the convenience of PoE can't justify the risk of sending 120V to all nic cards on the network. That just my opinion.

In 10 years, managing over 60 poe Cisco switches, this has literally never happened... Your fears are unfounded and you should read up on the technology a little bit.

 

[marbus90]

120V? I raise you 230V... and we've even did the unthinkable and switched from separate networks for internet and intranet to VLANs.

Are you scared of those loud and rumbling cars as well? ;)

Perhaps you are right about Cisco switches in production environment, but can you guaranteed this will not happened with consumer grade Poe Switches that cost less than shipping empty box from china.

I don't understand the complete technology behind it , but I think we can't compare the results from a switches that cost about small car to switch that is cheaper than meal in MC Donald's.

It's just my opinion , no argument. Actually it's not just my opinion , there was a class I watched talking about risks of PoE with poor quality switches, but I am not interested in debate about it.

 

[marbus90]

As for china crackers, those earned their name anyway.

Well, y'know, you're putting 115V (or 230V) into the device, and so it's possible something could go catastrophically wrong and it could start sending that out the ethernet ports, regardless of whether or not the switch handles PoE... ;-)

But seriously a switch that actually supports PoE has a complex negotiation protocol and won't power a port that hasn't negotiated power. Passive PoE injectors, in comparison, are a more risky proposition because they're just blindly injecting power into a line, and rely on you to make sure you've not done something dumb. And for the ultimate in paranoia, you can get a managed switch that allows you to configure whether or not to even offer power on a port in the first place, in which case a port needs to be configured for PoE and then also needs a PoE compliant client connected to it before power will be transmitted.

Is there such a thing as a "passive" POE injector? It would seem to be a very bad idea. I am assuming the D-link ones I've got properly negotiate the voltage with the other end, dependent on cable length and current draw. I could check, I suppose.

 

[jgreco]

Well of course there's such a thing as a passive PoE injector. VoIP phones, wireless AP's, network cameras, desktop ethernet switches powered by PoE, etc., can all benefit from PoE and many of those devices offer passive injector options. And you know what they say about standards, the great thing is that there's so many to choose from, so passive injectors offer that totally awesome possibility that you plug in one vendor's PoE device to a wall jack that has PoE injected by another vendor's crappy passive injector and get magic smoke.

My particular favorites are Cisco 7940/7960 phones which use "Cisco Inline Power" (pre-standard 802.3-af) which has the positive and negative power pairs reversed.

So I got tired of it all and have been buying PoE switches. For the CIP gear they still get wired funny but we do that at the phone (special cable from the wall to the phone). Then we configure the switch for 802.3af+legacy and all is good. I've been very pleased with the Dell PowerConnect 7048P's for this purpose. (Not a recommendation, NOT a beginner level product).

I am assuming the D-link ones I've got properly negotiate the voltage with the other end, dependent on cable length and current draw. I could check, I suppose.

Yeah, ah, ahaha, ahahahahaaahahahhahah, ahahahahahahahhahahahah don't make me laugh so early in the morning.

 

[rogerh]

Well, they work. And the equipment they are powering (AP, camera) hasn't failed yet. I shall carry on with my blind faith. Talking of blind faith, I would expect an ordinary NIC not to be harmed by 60V common mode, so it shouldn't matter plugging the wrong thing in. But I can't find an official spec for this. I doubt if even Cisco would apply 60v differential voltage across a pair, but that would certainly terminate compatibility.
