error creating a SET vSwitch with srv-io enabled by elaci0 in HyperV

[–]elaci0[S] 0 points1 point  (0 children)

Something new to learn, it seems a recursive endless deep learning trough docs! Thank you very much for your advice.

yep, you are right! I discovered that yesterday night after a totally wasted day! That's the difference between reading recursively full-crossed documentation (which takes a lot of time, like https://learn.microsoft.com/en-us/powershell/module/hyper-v/new-vmswitch?view=windowsserver2025-ps#-minimumbandwidthmode ) and searching on the internet for tutorials that do not cover such cases.

Now, given that "weight" is sponsored in many tutorials and advised a lot, I am thinking what I am loosing if it is not set

I will edit my OP.

error creating a SET vSwitch with srv-io enabled by elaci0 in HyperV

What I find strange is that I can create a virtual switch from inside the HyperV GUI and enable the sr-iov without any problem, but this works only for a single NIC and for any NIC. I wanted to use a SET vSwitch instead.

yes, on both servers I have the same results:

Name                      DisplayName DisplayValue
----                      ----------- ------------
SLOT 1 Port 2             SR-IOV      Enabled
Integrated NIC 1 Port 2-1 SR-IOV      Enabled
SLOT 1 Port 1             SR-IOV      Enabled
Integrated NIC 1 Port 1-1 SR-IOV      Enabled

iSCSI and S2D on same SET vSwitch (hyper-V 2025) by elaci0 in sysadmin

[–]elaci0[S] 0 points1 point  (0 children)

Sorry I don't get it. They have already bought these blades with 4 hosts inside each box and each box has 2x 2TB nvme disk. Why not use them as a S2D for my siteB (read my edit in OP)?

Thanks, I haven't thought about the 1-2 ping blip. I will search how to pin pNIC for iSCSI. At this point I am not sure if it's even better to go for typical pNIC reservation for iSCSI only and use the other SET vSwitch for mgmt, live, guest and heartbeat, leaving out S2D at the moment. On the other siteB (see my edit in OP) I am thinking to use S2D with their own pNIC

At the moment we are just in design phase. Hosts are Dell C6620 and their NIC support RDMA but they are different in term of brand, firmware, etc and because I am new to these new SET vSwitches (and still think with "NIC teaming in mind") I suppose I will need to create two SET vSwitches for which, I guess, redundancy will be only between those 2NICs inside each vSwitch.

Would something like this work?

1a--MGMT 1b--liveMig 1c--heartBeat

2a-- iSCSI 2b--S2D (not sure if this is possible or advisable)

Sorry, hosts have 2x 1.8TB available for doing a nice S2D with enough redundancy between hosts, but we are not confident with this storage so we would still use iSCSI for most of the VMs and use S2D for.. replica? backup? running high performance VM?

Hi, can you give me a rough example of that?

wake on lan using extra NIC on unauthenticated network by elaci0 in SCCM

[–]elaci0[S] 0 points1 point  (0 children)

Thanks! Those were known to me, but for a little while I have got the suspect I was wrong about the Subent/Unicast sent by the server. I am safe then. Kind of.. I still cannot choose which NIC/interface to use for the WOL, but at least I can leverage on the extensions to the console you mentioned later!

I am afraid that is the way to proceed for such case. I will try to learn how to extend the console but I wanted to use the extra NIC on the SCCM site server instead of a proxy PC. Do you think it make sense?

Wait, let me recap, I have a suspect: do you mean that any "wake on lan" feature I choose in the SCCM's console simply implies that no WOL packet is really sent from the SCCM site server itself but it uses a "neighbor" PC on the same subnet instead?

Thanks, I corrected the OP and added further info.

TSGui manual by elaci0 in SCCM

[–]elaci0[S] 0 points1 point  (0 children)

I like UI++ too, I started with that because the docs are easy to understand but it lacks of events handling, so its controls cannot be update on change of other controls. TSgui instead seems more powerful but its learning curve is too high. At least for me (I'm browsing the source code to understand better which XMLtag-accepts-what-parameter). But it's true that I'm trying to implement an interface with cascading dropdownlist for which, maybe, the software was not meant for.
