    Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

    Yup. Classic shelf style mount. Turns any 1u device into a 2u device with some storage space on top! Great if you need somewhere to put your modem!

    Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

    So I know a lot of people are happy just mounting these by the ears, and that's excellent if you have it set on something stationary, or just hanging freely on its own, but if you've got sliding servers underneath it, you don't want any sag on the device. Your options are generic "Shelf" style...

    Beware of EMC switches sold as Mellanox SX6XXX on eBay

    Okay, I've searched everywhere, but I can't find any documentation, what is FCF? I found vague allusions that it's something Fibre Channel related, and I do love my some Fibre Channel stuff, but I loaded a license with FCF enabled and can't see any option for FC anywhere.

    The Dell PowerEdge C6320/C6300 Mega Thread

    So I can finally confirm that 64GB 4rx4 LRDIMMs work if you have more than 8 of them, and you can in fact have >> 512GB of RAM. It seems that everything works. I don't have enough memory to leave this configuration in this system and run it full time, but I'll run through another round of...

    2 x Xeon E5-2620 V1, SATA DOM 5v USB Header Adapters

    I am in need of some very, very custom cables here, as I'm working with a very niche system. Can you tell me what part to order to get the satadom side of the connector? I've been searching for its name for about an hour and haven't been able to track it down.

    The Dell PowerEdge C6320/C6300 Mega Thread

    I'm in the process of upgrading my system to support Mellanox QSFP NICs, and I can't get the right Mezzanine Bracket. I got one kit which included the MW5RY riser, and that also exhibits the temporary short behaviour you described. Removing the blade and the card and the system seems to be...

    The Dell PowerEdge C6320/C6300 Mega Thread

    Be me. Get one of these for your birthday with no CPUs or RAM, and want to kit it out gradually over time. Decide to put one CPU and one DIMM per system, just to avoid having to buy more right now. Have a panic attack when you boot up something that was working before to test it, but no...

    Dell R630 rNDC in a Dell R620

    So I tried to 'delete' the oprom, and flint told me it couldn't delete the oprom because it contained important data. So I gave up on that, then I tried to set the configuration to enable the 62 SRIOV VFIs that the device allegedly supports, and when I rebooted, debian was like "Is this a NIC?"...

    Guide: Flashing H310/H710/H810 Mini & full size to IT Mode

    Very odd request, but can you add an additional section to Introduction - Fohdeesha Docs that explains what the various included boot firmwares are, such as the P16s and the ms-signed-* ?

    Dell R630 rNDC in a Dell R620

    So I'm running a Dell R620, and I picked up this nice Mellanox LX EN Connectx-4 rNDC (Part number R887V) which was designed for a Dell R630. Once I get into the OS and am running debian or FreeBSD, it's perfectly detected with no issues, and AFAICT, it passes traffic with no issue. However...

    Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

    Does anybody know the resister values, or have a guide for physically reversing the fan trays? Or perhaps more importantly, the psu? I could only get I models, but I need E for my rack configuration. I could just swap the fans and leave them reporting I, but that feels wrong and dirty.

    The Dell PowerEdge C6220 Thread

    I apologize for the poor quality of the photos, but as you'll see, one has a dip pin header, and the other has a second mezzanine card connector offset and back from the main connector.

    The Dell PowerEdge C6220 Thread

    I'm looking at buying one of these, and I noticed something strange while searching that I can't clear up, but that matters for my use case. Some C6220 motherboards/Nodes seem to have two mezzanine card slots, implying the possibility to have both 40GBE/Infiniband as well as the Internal SAS...

    Dell R710 with mismatched CPUs

    @msg7086 @BlueFox Thank you both. Any chance you could cite the source you're quoting so I can review it for other useful information and to just have for future reference?

    Dell R710 with mismatched CPUs

    Do you happen to know the requirements to make it work within generations? What specs or settings are crucial? Which are irrelevant? What should I check?

    Dell R710 with mismatched CPUs

    Will a Dell R710 function properly with mismatched CPUs? I've got 4 Xeon CPUs CPUs. 2x E5645, and 2x E5503. I have two R710 servers. I want to keep the two balanced. I could buy more E5645s if I need to, but that'll be a week of shipping. I'd like to get it up and running as two...

    A few QLE8362 Questions

    Has anybody used this card? It's an awesome card on paper, that supports both Fibre Channel 16G and 10GBE, but I haven't been able to find much mention of it online. The QLE2462. QLE2562, etc. products dominate the searches. So I'm hoping to find someone with some experience with the cards to...

    38mm vs 40mm fans

    So after much research and a lot of nothing, I decided to buy a trio of Noctua NF-A4x20 PWM fans for USD $15 each. They're a little shorter than the 38x38x38 fans, but the 38x38x38 fans are about half plastic reinforcement and half fan. So I don't have significantly less fan. That said, when I...

    38mm vs 40mm fans

    Are 38mm and 40mm fans two different names for the same physical fans? Or are 40mm fans actually 2 mm larger in the square dimension? I'd like to buy some 40mm fans to test-fit them in a 38mm fan location, but I don't want to waste the time and money if it's not going to work out. Also, is...

    Infiniband QDR vs FDR

    So I know Infiniband QDR is 40Gbps with 8/10 encoding and FDR is 56 Gbps with 64/66 encoding, but one question I can never find answered anywhere is as follows: Can an infinband QDR card connect to an infinband FDR switch with reduced throughput compared to the rest of the network? Can an...
