Check the disk scheduler on the Dom0 for this drive.

@jsajous26 said in Avis et retour sur utilisation de stockage NetAPP:

Bonjour,

• 1798MB/s en lecture, fait environ 15Gbits/s
• 1196MB/s en écriture fait environ 10Gbits/s

C'est tout à fait dans la norme pour un benchmark sur un seul disque. À noter que cela passe à l'échelle avec le nombre de VHD, ce qui fait que dans un contexte de production réaliste (des dizaines de VHD qui écrivent/lisent en même temps), on arrive à saturer un lien 25G.

Nous travaillons en parallèle sur 2 axes :

• amélioration (multiqueue) de tapdisk pour la performance sur un seul disque
• utilisation de l'équivalent de Vvols en parlant directement à la baie pour éviter des conversion de format et bénéficier des performances natives (ou proche) de la baie de stockage.

Congrats!

We do upgrade drivers, especially via alt, it's pretty safe (LTS doesn't mean frozen drivers). @stormi could confirm.

I edited your post with Markdown code block, it's a lot easier to read. @florent will take a look when he can.

Weird, have you looked at the usual logs?

Okay weird, so having a very different RAM usage with Node 24 should be checked when we'll update XOA Node version.

can you remind me the Node version you have, that is exhibiting the problem?

No but maybe @Team-Hypervisor-Kernel does

Ping @thomas-dkmt for better doc clarity about it.

1. Pool metadata: backup metadata of your physical XCP-ng host
2. XO configuration backup: backup data of your Xen Orchestra instance.

Question for @yann or @teddyastie I assume

Hi,

Try to restart the toolstack and see if it persists

You need to forget them, not remove.

Hi,

Can you give a bit more context? Is it XOA? Or XO from the sources?

Note we already gave visibility on this project twice, with the last 2 XO blog post release and newsletter

Hi,

It's already planned, but in XO 6, you already have better tasks displayed (you can even track an entire RPU there)

Ahh excellent news. So indeed the new kernel sees the device USB policy will be improved in the future so it's kept after updates, so doing it once will be enough.

Thanks for testing!

Yes, we'll update the doc

That's precisely the value of XOA and why we are selling it. If you want best tested/stability, XOA is the way to go
