Supermicro 4u 24 bay chassis with SAS2 expander

Interesting metrics, and yeah I forgot to mention I have the 1200W gold rated PSUs.
By the way, can you send me a link to the auction or at least the part number/model of that 6 port gigabit NIC you have? I'm highly interested in getting one, didn't know GbE cards went above 4 port models.

I've bought 2 of them. They're cheap and work good.

the chipset on that doesn't seem to support from what i can tell intel's VMDq technology, any idea if that really makes a difference at all versus NICs that don't have VMDq?
Isn't VMDq used to offload network processing from Hyper-V to the NIC's hardware itself (hardware vs software)? Also used in teaming (doubling up) across 2 or more NICs?
VMDq has nothing to do with the teaming of NICs but it does do I/O offloading in Hyper-V and is an important part of optimizing a Hyper-V hosts for performance.
The Intel i350 cards have VMDq and are around $50:

Though, all the "$60" versions are from China/Hong Kong (gotta wait for them). All the ones state-side are > $110.
Humm, I may just pick one of these up...

if you looks on 500W Platinum -> http://www.supermicro.com/products/powersupply/80PLUS/80PLUS_PWS-501P-1R.pdfThis is my idle power consumption from my server with 2x X5650 cpus, 48GB, and 12x3.5" disks, do you guys think I can lower the amps/wattage consumed by down-sizing to lower wattage PSUs, at least, by an amount that's worth spending moneyo n?
50W output 88.23% eff
100W output 93.01% eff
250W output 94.44% eff
500W output 92.47% eff

bold highlighted is a sweat spot to save power
Platinum:
500W still the best bet for low noise and low power consumption for average 100-250W or 369W for 740 w
compared with 1200W gold, 92% eff is the sweet spot with 604W power output .
I believe, you can decide by pooling pdf files from SuperMicro site.
on my knowledge, 5ooW platinum still the best when the system unit is pooling 100-250W..
side note:
20W reduced when I switch to 500W platinum from 1200W gold. and very quite too (not whisper desktop psu quite
). Noise or not is not really matter now due on everything is in my closed rack server...

if you the consequences buying from overseas China card
, you are goodbefore you buy, search on the net regarding "clone"/fake" chip that could not achieve the original one.
search on "counterfeit intel nic" <- the most counterfeit due on popularity ha..
I bought One , 3 years ago. very cheap on missing heatsink. I paid ~$30
..since the chipset is pretty old and using pci-e switch. power consumption is pretty high. watchout on PCI-e switch. the heatsink need average air-flow.
Mounting 2.5" SSDs in the 3.5" bay slots... Do you need a special Supermicro adapter, or will a normal 3.5" -> 2.5" adapter work?
My 3rd one just arrived. Both will now have the SAS2 backplane. It didn't include PSU's but I just upgraded the other to 700w platinums and so had a couple of 1200w. I also ordered another X8DT6-F MB so I can put the chassis with the SAS1 backplane back on eBay as a full system minus HDs and OS. I have 2 spare cpus, heatsinks and 16gb of ram. I figured this was a good way to off load the extra parts I had.
Hopefully I'm done for a while.

OK, it's mystery time. This chassis has a little board in it I didn't see in the other two. I went through the manual and it's not shown or mentioned. Does anybody know what it is?
It's got a long cable running from it.
At first I thought it was an intrusion switch but it's not a switch at all and it doesn't penetrate the side of the chassis.
Would someone kindly tell me what I have to do to embed pics? Thanks

that's the front IO board, 2 of the cases you got didn't have that? that cable ribbon hooks up to the pin-out on the mobo for the network/disk activity LEDs, power/reset buttons, and anything else included in the front panel.
lol, you should take pictures of the exact same spot in the other two cases and show us them, and, then ask the seller how exactly he thought you were going to turn your servers on? i mean you COULD use a flat head screw driver to close the circuit on the PWR jumper but come on.
