Hello
to increase our proxmox ceph storage cluster reliability, I'm looking to upgrade ceph network from Intel 10G ethernet to SFP+ .
we have an issue with slow requests , much like this person had Ceph, SolarFlare and Proxmox – slow requests are blocked . the issue has been going on since we started using ceph in production 18 months ago. 99 times out of 100 it happens for about 20 seconds per day.
they solved the issue by using recent kernel modules from Solarflare. Now I never heard of Solarflare until today , and am impressed by their 'Kernel bypass' method. However each kernel upgrade would require a dkms module build. I've done that in the past for zfs . It is not hard just a point of failure if not done prior to reboot.
Chelsio on the other hand has modules in Debian non free . I am not sure how up to date those are.. However there are no debs for Solarflare.
researching which is better is almost impossible due to all the marketing clutter. I suspect both companies have awesome products.
My question:
When comparing recent model cards - is Chelsio as good as Solarflare ? By good I mean ultra low latency, and not bothered if the linux lernel is busy dealing with rsync or backups?
thanks for reading and best regards, Rob.
