I hope this is the right place to ask this question:

Does the population of nvme slots subtract from the max number of PCIe lanes?

Usually a NVMe SSD connection slot is connected by a PCIe x4 interface.

I would like to use the w-1290t which officially offers Max# of PCIe lanes of 16.

I would like to use two lsi raid controllers, which each use 8x PCIe lanes, leaving 0 for the 2 NVMe SSDs, which I would like to use.

Thank you for your help 🙂

Shaun, I agree it looks like a DVI-I Port, but I don’t think it support Analog. The P630 iGPU used in most of these GPUs only supports Digital Output, not Analog. Additionally, the Block diagram shows the Display connections connected to the Digital Ouput links directly from the CPU. Without an active circuit to convert one of the digital connections to Analog, it’s not going to be putting out any Analog signal from that port. You do however get VGA directly from the BMC if you get the SCA-F variant.

DVI-D? That looks like DVI-I to me (meaning it supports DVI-A/VGA with an adapter which is probably important given the common use of VGA for KVM’s and such in servers.

this is a minor update to the X11SCA-F :
+ updated platform to w480
+ added one usb3.1 gen 2 port
– removed one pcie3 x1 slot
+ added one 2.5GbE port (thus dedicated GbE for IPMI)
– removed four SATA 3.0 ports
+ added dedicated M2-slot (previously shared with PCIe x4 slot)

in a nutshell it’s a bit more flexible by swapping 4 HSIO-lanes from SATA to PCIe. although it’s a shame they didn’t opt for a 5GbE port.

Disappointed in SuperMicro for selecting the i225-V variant. Unless something has changed, the -V SKUs are not officially supported in Windows Server. You can make it work, but you have to modify the driver files.

The X12SCA-F product page lists the i225LM for the 2nd NIC instead of the -V. Understandable product segmentation I suppose, but still annoying.
