epct utiliit - os käsurida
epct võiks olla väga asjakohane tööriist, aga 2024 aasta kevadel ta praktiliselt eriti ei tööta, ei linux kernel v 6.x ega v. 5.x puhul
kui ice draiver on laaditud

epct utiliit - efi rakendus
epct efi rakendus natuke töötab, aga ei võimalda siis 'svio enable' teha, https://www.intel.com/content/www/us/en/download/19440/ethernet-port-configuration-tool-efi.html
nvmeupdate efi rakendus iseenesest ei anna viga, aga ei saa ka aru, et süsteemis oleks e810 kaart, https://www.intel.com/content/www/us/en/download/19629/non-volatile-memory-nvm-update-utility-for-intel-ethernet-network-adapters-e810-series-efi.html

Kasutada on üks füüsiline kahe pordiga võrgukaart

RoCEv2 kasutamine
Oluline on, et see ip konf millega opereeritakse järgnevalt oleks kinnitatud füüsilise seadme külge (st mitte nii, et arvutis on kasutusel nt OVS virtual switch ning ip on vlan47 küljes, sama ovs bridge küljes on füüsiline enp129s0f1np1 jne, st siis ei toimi)
root@pve-02:~# ip addr show dev enp129s0f1np1:

Muu hulgas toetab see seade iwarp ja rocev2 protokolle, devlink vaatest paistab see nii
# devlink dev param
pci/0000:81:00.0:
name enable_roce type generic
values:
cmode runtime value true
name enable_iwarp type generic
values:
cmode runtime value false
pci/0000:81:00.1:
name enable_roce type generic
values:
cmode runtime value false
name enable_iwarp type generic
values:
cmode runtime value true
Korraga saab olla aktiivne üks või teine, nende vahel valmine toimub nt selliselt devlink abil
# devlink dev param set pci/0000:81:00.1 name enable_iwarp value false cmode runtime
rocev2 kasutamiseks on asjakohen süsteemidesse paigaldada omajagu rdma ja infiniband traditsiooniga tarkvara, nt
# apt-get install rdma-core # apt-get install perftest # apt-get install ibverbs-utils # apt-get install infiniband-diags # apt-get install ibverbs-providers
Asjasse puutuvad sellised driverid
- ice - põhi draiver
- irdma - intel võrgukaartide (2024 aastal e810 ja midagi vanemat ka) - 'intel rdma'
Seadmed kui rdma seadmed paistavad
root@pve-01:~# rdma link link rocep129s0f0/1 state ACTIVE physical_state LINK_UP netdev enp129s0f0np0 link rocep129s0f1/1 state ACTIVE physical_state LINK_UP netdev enp129s0f1np1
Kahe otse kaabliga süsteemi uurimiseks sobib öelda ühes ja teises arvutis nt nii, pve-02 on nö rping server ja pve-01 on rping klient; seejuures on iseloomulik, et tavalise võrguliidese peal tavalisel viisil võrku pealt kuulates ei ole midagi näha
