10Gb SFP+ single port = cheaper than dirt

[Spartus]

I have yet to try a transceiver that didnt work. Mellanox (obviously), dell, and finistar so far.
I tried also an active DAC from brocade, was fine. never used passive, I tend to use optics.

 

[Chuckleb]

We too switched over to optics and all you mentioned are great. For copper, we have done Mellanox and some no-name brands off eBay, all worked fine.

I just put in an offer of $26 for two of the cards, hopefully he accepts it! Does anyone know if this works with ESXi 6.0? If not, I guess I can vt-d it to one of my W2K12 R2 guests.

Any suggestions on a SFP+ direct attach cable? The servers are sitting on top of each other, so I only need half a metre or so.

Does anyone know if this works with ESXi 6.0?

They should work great in ESXi 6.0. I have a number of the dual-port version of these ConnectX-2 EN cards in ESXi machines and they work wonderfully! They're supported with the built-in drivers, too! (Well, not "supported" by Mellanox anymore, but you don't need to hack in drivers or anything -- they work with what's built in).

 

[Aluminum]

Mellanox doesn't do stupid eeprom checks on plug-in modules AFAIK, so anything that conforms to the port type should work.

They really should have written that stupidly abused option out of the spec with QSFP, sigh, maybe the next widely used network port design will.

BTW:

(or take the money you'd spend on an add-in NIC and buy a slightly better motherboard to begin with)

Some board configurations there really is no other choice, realjunk is the ultimate shovelware peddler of chipsets and a lot of OEMs just can't resist

The esiso guy is not taking less than $34 for two. Has anyone else been able to get them for less?

 

[BackupProphet]

No, I just bought 20 and and paid $18 per card.

Anyone knows a good cable to use to put 2 cards on crossover ???

Genuine Cisco Dell SFP H10GB CU5M SFF Twinax Copper Cable 5M J564N | eBay That would work??

Thanks!

Do you need 5m? Passive at 5m is on the longer side I'd think. You can direct connect using DACs.

Hi Homelab74656,

I actually made a single offer of $30 for pair, to which Esisoinc counter with even cheaper $28 for the pair. Obviously, I accepted his first counter offer ...Maybe Esisoinc is running low on stock now? ...Maybe Esisoinc gave me deal for buying from him before (Esisoinc has been great seller with me). ...Sorry, don't know what happened with your bid, but you might mention my $28 deal and not push lower.

Regrets,
Abq

That'd probably be ok.

Thanks for the help. I just made another counter offer for $28 and asked if the deal was for everyone, or just some users. I guess we will see!

this depends on your motherboard (passthrough) pci lanes !

 

[JayG30]

Same result, seller countered at $34 for a pair ($17/each).
Going to buy 2 pairs (4 total) just because. I mean, $17/each is pretty amazing even if some people got it a few bucks cheaper.

Send another offer in, with a message that states, that they sold a pair to others for $28, is this a special deal only some people get?

That's what I did, no response though

I'd spend more time working on cables and optics than trying to get $4 per card off.
