    Xeon 8272CL Maximum Memory

    I'm going to give this a shot and see what happens. I will be testing a 24 DIMM system (12 per socket) with dual Xeon 8272CL CPUs (stated compatible by vendor), 12 LRDIMM 64GB (6 per socket) and 12 512GB Intel Optane Persistent Memory DIMMs (6 per socket). This will be 768GB of RAM, 6,144GB of...

    Xeon 8272CL Maximum Memory

    I have been researching this CPU and have seen numerous conflicting specs regarding the maximum memory supported by this CPU. Some say 1TB per socket while others say 4.5TB per socket. I'm hoping someone on here might be able to report real world experience with trying to push beyond 1TB on a...

    Hyve "S-SKUD 2" - 1U, 8x LFF SATA6, 2x LGA 3647 Skylake-SP, 2x PCIe x16, 2x OCP PCIe x8 w/2x 25Gbps Connectx-4 installed - $179 + Shipping

    A system can support both NVDIMM and Intel Optane Persistent Memory options... just not both being used at the same time.... if that makes sense. It unfortunately isn't looking too promising that this motherboard supports Optane Persistent Memory though, so it likely also doesn't support Gen2...

    My gut is that has to do with Micron's NVDIMMs rather than Intel's Optane Persistent Mem. Hmmm. If you're in the market for a regular Gen1, check out Xeon 6138 CPUs on Ebay. Lots of server pulls going for less than $300 currently. With 20 physical cores, 40 threads, they're outstanding...

    Does it mention Intel DCPMEM (Intel Optane Persistent Memory) in the Bios? I believe it's usually under the Advanced menu. If it does, this means at least mainstream Gen2 CPUs should work.

    The BMC is AMI MegaRAC. Quite a few names use it for their BMC solution. Gigabyte, some of HPE's Cloudline (at least the ones made by Gigabyte for them), AsRock, Asus, Tyan, some Intel boards, Chenbro, Wistron private label/oem, and several others use that same BMC. It's pretty common...

    That's how I'm leaning as well. Usually, when you see the black DIMM slots closest to the CPU like that, they're for optional Optane Persistent Memory DIMMs, and those are only supported on the Gen 2 CPUs. However, just because the board can support Gen 2 doesn't mean the BIOS version does...

    Curious... Is this strictly skylake (gen 1) or cascade lake (gen 2) as well?

    Supermicro SAS3 HBA

    You probably don't need to mess with cross flashing it. I have deployed several of these in non-supermicro machines/motherboards without any issue. They just work as is.

    Beware of EMC switches sold as Mellanox SX6XXX on eBay

    I just configured two SX6036 switches this week (SX6012 works the same way). Try following the instructions in the manual, starting on page 43. You can launch the wizard, and it'll allow you to set the switch up as a dhcp client on the mgmt port. Once you've done that, hook the mgmt port of the...

    Chenbro RB238G13-U04 - 10G Fiber Adapter

    Tried a Mellanox ConnectX-3 dual port QSFP card today. It was correctly recognized in Windows 2019.

    Supermicro SAS3 HBA

    I needed some with half height brackets, and I found these for a few bucks less (but no best offer option). Still a few available, so thought I'd throw it up here in case anyone was needing the short bracket. :)...

    Chenbro RB238G13-U04 - 10G Fiber Adapter

    A little update... I spent the better part of a work day today trying to figure out why the Chenbro refuses to recognize an Intel Optane 905P NVME/U.2 drive, and unfortunately have still not figured it out. Pretty frustrating honestly. It's quite possible my cabling from the nvme/u.2 backplane...

    Chenbro RB238G13-U04 - 10G Fiber Adapter

    I am currently testing this Chenbro model in the lab with the intent to create a 3 node failover cluster using 3 of these systems. I've got several different SFP+ and QSFP cards available to test, but I'm planning to use ConnectX-3 dual QSFP cards for 40GbE storage networking, assuming they are...
