Gen 10 PCIe/NVMe Boot

There are dual M.2 NVMe PCIe cards with no PCIe switch chip, but they are very dependent on the way the system board bifurcates the PCIe slot. On the MS Gen10 Plus, the only bifurcation option for the x16 slot is x8 + x8. If they offered an option for x4 + x4 + x4 + x4, that would likely work with the non-switched cards.

I'm going to try and measure the power usage of the machine under load before possibly trying the Lycom DT-130 with the two NVMes.

My plan was to build an Storage volume (storage spaces microsoft) with 4x10TB (disks) and 2x1TB (m.2) and create a Tiered cached config. I've built a 8bay unit like this using a ASRock X470D4U2-2T, U-NAS NSC-810A Server Chassis and  LSI M1015 SAS9211-8 (HBA) for the disks. M.2 are on the motherboard and a SATA SSD is used as boot volume connected to onboard SATA.

 

Trying to accomplished something similar based on the gen10 plus. Got to figure out what to boot from though. Any ideas here?

I could settle for 2x10TB disks (or bigger) and boot from an SSD in one of the bays.

 

If bios is updated to support bifurcation 4x4x4x4 then this is not a problem as you can buy a cheap 4 slot m.2 pcie and have it boot from a 3rd M.2 attached to that.

I upvoted a thread I found on bifurcation in hp support forums, https://community.hpe.com/t5/proliant-servers-netservers/microserver-gen10-plus-pcie-bifurcation-support-issue/td-p/7092453#

 

Brgs,

Hello, good afternoon.


I am interested in purchasing a Gen10+, and I wanted to ask you if the integrated controller detects NVMe/SATA drives located in a PCI adapter, to install the operating system. I only want to incorporate an M.2, I don't need to do RAID. Thank you!

Hi,

 

Yes it does, I’m running Server 2022 quite happily off an M.2 on a PCI-E card.

But the HP embedded controller detects SSDs in the PCI section? And NVME drives are also detected? Thank you.

I have 2 x SSDs and 2 x HDDs in the drive bays, then the 2 x M.2s on the PCI-E card, the operating system is on one of the M.2s and works perfectly.

Hello, good morning.

 

But the M.2 devices you have built in are SATA or NVMe? Because I've been reading around the forum that sometimes they are not compatible, or not compatible at all.

 

How does the integrated controller manage all the storage drives? I mean if there is any performance drop in the communication between the storage devices that are connected to the PCI, and the drives that are in the bays.

 

I would like to install Windows Server 2019 on the PCI drive, and us the performance it will have communicating with the server bays. Thanks!
