How will that affect VMs that use more CPUs than a single NUMA node has? As for 30 Gb/s being fast. Sure, to some. But I'm trying to take advantage of some fast NVMe pools I have on another VM that are capable of 10GB/s.

Is that what this checkbox does essentially?

I'm trying to increase the networking performance between 2 Linux VM's on the same Proxmox host and bridge. I've tried both a Linux bridge and OVS bridge. I've tried increasing MTU to 900o and multiqueue to 4. I can't seem to get above 25-30Gbps between the VMs. I'm running these VM's on an...

Yes. Also, the Opitimize-Volume command works on C but most of my data (12TB+) is on D. And the command fails on D with... > Optimize-Volume -DriveLetter D -ReTrim -Verbose VERBOSE: Invoking retrim on Data (D:)... VERBOSE: Performing pass 1: VERBOSE: Retrim: 0% complete... Optimize-Volume...

Would i set discard and SSD emulation back to off after running the Optimize-Volume?

I call it a backup because it's a File Backup server that gets file backups replicated to it using the software Vembu. There is a main file backup server running Vembu and then this one that the data gets replicated to. I'm well aware of the potential performance pitfalls but I don't have a...

Good to know :D.

I'm less worried about changing the settings than the Optimize-Volume -Retrim command. Hard to snapshot/backup a 14TB vdisk :D.

Is there any risk of data loss with this method? My disk is attached as scsi0 with a VirtIO SCSI single controller. I'd have to shut the VM down and tick off discard and SSD emulation and then boot the VM back into Windows to run these commands.

As I've said in multiple posts, a hardware raid controller is not available/an option. And I have a 14TB VMware vdisk of data I need to maintain.

Thanks, that's exactly what I did last night and I have the import running now. Right now it's 60% done with 8.3 TiB transferred of 14.1TiB. Current state of the datastore is... # zfs list NAME USED AVAIL REFER MOUNTPOINT chs-vm01-datastore01...

I appreciate your reply but I'm not going to get into different hardware possibilities because, honestly it's just moot at this time. The situation (at work, this is not a home server) is I have the following hardware that I need to migrate a VMware 14TB vdisk to in the next few weeks. I did...

It's not an option unfortunately. I would have done that in a heartbeat but I'm forced to swap hosts as well and the newer hosts are coming from being VMware VSAN nodes that didn't come with or need hardware raid controllers. So...I'm here now. I don't have any preference as to what FS I use...

I just don't really have a choice. Being forced off VMware due to licensing increases and need move over to Proxmox. The move also means moving my 9 disks from a hardware raid controller to passthrough so it's either ZFS RAIDz1 or mdadm which isn't officially supported.
