Bifurcation Hp Proliant dl380 gen9

[AttempGame]

Good afternoon, does the pcie server support bifurcation, installed the latest bios 2.90 firmware, installed the board in slot 4 (secondary)


I found this documentation, where it is indicated that it supports bifurcation, tell me what's wrong? 
support hpe com/hpesc/public/docDisplay?docLocale=en_US&docId=c05060771


Added support to configure the system to bifurcate PCIe Slot 1 on the DL360 Gen9 or PCIe Slot 2 on the DL380 Gen9

Hi,

PCIe Bifurcation option is not available as setting in Gen9 UEFI utilities (as of writing this post).
There are few other posts which discuss this:
https://community.hpe.com/t5/Servers-General/HPE-Proliant-dl160-gen9-bifurcation/td-p/7133232

Settings are only available in Gen10 Servers.

This is understandable, in the change log firmware ROM it was described that bifurcation support was added, it was in 2016, after there is no information about it, since it was added earlier, should this support be in subsequent versions? how should we do? we have nvme to pci x16 adapter for 4 disks

@Suman_1978 - I'm confused why you claim it's not available?

The very link you referenced, states that it is indeed available.

In addition, that same link references the HPE UEFI Release Notes PDF, which explicitly states that it's available, quote: PCIeSlot 2 on the DL380Gen9.

It's available under RBSU.

It's a hidden menu: when in RBSU, press CTRL+A. Then see bifurcation.

Did anyone get this to work?  I am running DL380 G9 with 2 x 2699v4 CPU's.  I have a Gen10 PCIe retimer card in slot 2 and is is enabled in BIOS.  It doesn't seem to see the U.2 PCIe Drive Bay with drives.  The drives work when in a pcie to U.2 adapter in the riser cards.

It would be nice to use the drives in standard carriers for easy maintainance.

Dear all,

STEP1: On my HP Proliant DL380 G9, there is a “hidden BIOS menu”. To
access that, press F10 and A. (not sure this is it).

NOTE: it”s been some time since I did it, so try to google “HP server BIOS
hidden menu”. You will find the right key combination to acces it!!!

STEP 2: Then, in BIOS will be available under Advanced… PCIe settings the
option to bifurcate the 2’nd PCIe slot. Unfortunately, on my server I can
do x8x8 only. There is no option like 4x4x4x4 as I need.

STEP3: Place in the 2’nd slot a 4x4x4x4 adapter (search Amazon for JEYI
https://www.amazon.com/Expansion-Supports-256Gbps-Support-Bifurcation/dp/B09F31ZXKQ
) with 1 and 3 ports filled with M.2 SSD. Boot the server normally.

You shoud see 2 x M.2 ssd in Disk Management. As the server can’t bifurcate
in 4x4x4x4, that means only the first segment of each x8 is available to
see some ssd.

I did”t try to setup the server with U.2 disks, but for sure this has
nothing to do with bifurcation. The manual is a joke for this configuration.
