Hi Guys,
so we have started using Proxmox, migrating from VMware, I currently have 4 Proxmox nodes in Cluster and already migrated almost 40 VM's.
everything is working as expected, migration doesn't take that much.
we are using a Compellent SC5020 as a shared Storage, VMware also uses the same storage, and I have 50TB.
what I have noticed is that the Read Latency for Proxmox nodes it always stuck on 10ms, I did open a ticket with Compellent CoPilot support but they couldn't figure out what is causing it, they suggested to change the or disable the delay ACK but this setting is for RedHat and I can't find any reference for it for Debian or Ubuntu.
so I open this Thread to see if anyone who uses the same setup experienced the same issue and the way they solved it, if they really did find a solution.
as I said everything works fine on Proxmox i'm even getting better performance than VMware.
here is some information:
SAN: Compellent SC5020 All-Flash
Servers: Dell R640 each with 4x10Gb Interfaces 2 for Multipath and 2 for VM traffic in Bond with OVS
Switches: 2x Dell S4048
Proxmox Package Version:
so please share your experience and the way you solved it.
Best Regards
