Can anyone guide me on whether this transceiver will work (at 40 Gbit, not 100 Gbit, obviously) with a Mellanox MT27500 Family 649281-B21 HP Infiniband FDR/Ethernet 10Gb/40Gb 2-port 544QSFP Adapter such as this one? Any firmware settings needed, or will it 'just work'? Currently card is working...

I have seen this type of issue with a Supermicro X9 board. The X9 boards use some lower resolution modes, like 640x480, 1024x600 and 1280x800. Cheaper VGA-to-HDMI converters only support the higher VGA resolutions (sometimes only 1920x1080). I bought this cheap VGA-to-HDMI adapter...

Yes - works for me now. My DNSSEC validating DNS server was rejecting broken DNSSEC for shucks.top

Can anyone reach shucks.top? I get a DNS failure

I use a couple of Supermicro X9DRH boards in a 4U chassis, and since I wanted them to be as silent as possible, I am using a pair of Noctua NH-U12DX i4. These coolers are a bit costly, but for about $15 each more than the Supermicro SNK-P0050AP4 , they support 2 fand on each cooler, and they...

Thanks for this useful table. I want to flash an onboard LSI 2208 on a Supermicro X9DRH-7F to IT firmware. What is the difference between flashing controller firmware and flashing the controller BIOS and/or EFI?

Thanks, @NateS

@juey : I just received my ICX 6450-24P. I do not use PoE and I have disabled PoE. The stock fans are still too loud for me. I am thinking of buying the Noctua NF-A4x20 FLX fans (I have been very happy with them in other switches like the Quanta LB9a). I have a few questions: - Will the...

And I suppose the 10G uplink will work (at 10Gbps) with a different model of switch also - I have a Quanta LB9A uplink switch

ccie4526: Thanks for your quick reply. I will not be using PoE, but I only find the PoE versions for sale on eBay. If I am not using PoE, can I disconnect both fans? Do the fans use standard 4-pin connectors? If I want to enable the second 2 10G ports, how do I get the adder license?

Thanks fohdeesha, for this fantastic information. I am thinking of buying a Brocade ICX-6450-24P. I only want the basic switch functionality, along with the ability to use one or more 10G SFP+ ports for uplinking to another switch. I will not be using PoE. Will I need special licenses for this?

On eBay: New SuperMicro CSE-836E16-R92JBD 3U 16 BAY 3.5 JBOD BPN-SAS2-836EL1 672042117420 | eBay 8 available. Looks like a great deal - sells retail for $1k+, best deal I have seen in the past was $700 or so. 2-year SquareTrade protection available for $33 too.

Thanks for your informative replies!

Thanks @Dreece You're right - probably makes sense to buy (and test) a cheak LSI 9200-81 to test any future SAS drives taking out any variables related to the enclosure being used. BTW, since I am new to SAS drives, if I used an "internal" HBA like the LSI 9200-81, I know I will need an...

The seller responded asking me to initiate a return. I will try buying a different SAS disk, and try that.

Thanks for your reply. Unfortunately, I have only one SAS HBA. I could buy a cheap HBA like an LSI 9200-8i, but it would be no use to me long term, and it would cost as much as the HDD in question. Unfortunately, I also cannot try the HGST SAS HDD in my Rackables enclosure though I have free...

I am a servethehome noob. I read posts all the time, but have rarely posted before. My setup: SGI Rackable SE3016 bought May-2016 LSI SAS 9200-8e HBA bought May-2016 Brand new SuperMicro CSE-836E16-R92JBD with BPN-SAS2-836EL1 backplane bought May-2020 I have 7 (SATA) disks in my SGI Rackables...

Thank you for the quick confirmation

Thank you for pointing out this deal. I want to use 2 of these to connect two linux servers. Can I use this cable (IBM 40GB/S MELLANOX INFINIBAND QSFP COPPER 1M CABLE CBL1-0600130-B-39.5-IBM | eBay) ?
