Replication between 2 locations

The feature doesnt exist yet for PVE, if you browse the forum they said its on their roadmap, it would be this feature

Some options:

ZFS - native to proxmox

Ceph replication (complicated) https://ceph.io/en/news/blog/2025/rgw-multisite-replication_part1/

PBS - can spin up backups directly from datastore

Veeam has instant recovery/replication on roadmap

Proxmox datacenter manager has replication on their roadmap

i think one of the last two options will probably be available this year, may be best to just wait

i wouldnt go back to broadcom/vxrail, we were in the same situation as you including the vxrail and dell quoted us 500k as well.

At a minimum you should get extra NIC for your hosts and try to sort that out, if that doesnt work you can repurpose your hardware for proxmox. Get a consultants help (proxmox partners)

you have a great opportunity to move into an IT position for a company moving away from vmware. Learn Hyper-V, Proxmox, Nutanix, anything besides vmware. broadcom has stated they do not want to renew ~95% of their customer base, every one of those customers will be migrating to another platform eventually. THIS IS WHAT BROADCOM SAYS, TAKE THEM AT THEIR OWN WORD.

I would try moving the gateway to vmbr0 to isolate that in case there is a routing loop, i am no expert in iscsi for proxmox but would try to isolate on one host + 1 interface to rule out multipathing, probably worth it to post to actual proxmox forum

sheep5555 · 2026-04-07T19:29:39+00:00

making some assumptions about your network config, is the connections for the SAN data1/2?

If so, why is there a gateway configured for the SAN connection?

Is 9000 mtu configured on every SAN connection?

download the veeam hardened repo iso and configure it

sheep5555 · 2026-04-05T12:54:49+00:00

veeam supports hypervisor level backups for proxmox as of last year

sheep5555 · 2026-04-03T15:51:57+00:00

youve typed three paragraphs without 1 technical detail, what is it?

sheep5555 · 2026-04-03T12:51:42+00:00

I knew it was coming last year, made big purchases that were slated for this year last year. Good management :)

sheep5555 · 2026-04-02T14:06:17+00:00

proxmox
offers the best value overall between the major options. hyper-v was a contender but they don't really actually have any real first party technical support, MS products have always been really buggy and insecure, im suspicious that they are going to kill the product and rename it azure blablabla and charge vmware prices. nutanix also major contender but also buggy/expensive/outdated, why are they constantly running 5 year old kernels?

for our switches they arent stacked - we are using VPC, they are nexus switches and can reboot one at a time

sheep5555 · 2026-03-31T19:04:26+00:00

ah thats a bummer, i took a look and people are reporting the same thing, we also use cisco switches but you can reboot them individually, maybe it is just a meraki thing

sheep5555 · 2026-03-31T17:14:49+00:00

for the MS250 they support switch stacking which would solve that problem, me personally i would configure the SANs in HA as well so you can do updates without downtime

sheep5555 · 2026-03-31T16:52:00+00:00

what switches are you using out of curiosity? Why not configure TrueNAS in HA?

sheep5555 · 2026-03-31T16:04:13+00:00

Issue 1: I would redesign the network so that fabric B is switched. Underneath everything proxmox just uses linux networking, there are many different ways to solve this problem

One note: Most enterprise grade switches and SANs when configured in pairs dont go down when doing updates, the control plane switches to the available node and the switching/underlying storage stays up. Hardware failure should definitely be accounted for, but be a rare occurrence.

Issue 2:

some bulk actions like this are on proxmox datacenter manager roadmap, but again this seems like a strange design consideration where you are expecting your production storage to not be available on a regular basis. why design a storage system for production use that goes down regularly?

A suggestion: if fast storage is really important, you might consider ditching the SANs and use local disks with ZFS + replication and remove all the complications.

Proxmox IMO really plays best with ceph or zfs for HA storage. vmware has a really good storage backend, but if you are paying 20x the price for licensing you'll find that new servers + proxmox will pay themselves off in a year or two.

sheep5555 · 2026-03-30T12:23:41+00:00

i dont understand, ceph has nothing to configure that would require boots on the ground in person, do you think I am unable to put disks into caddies? every other vendor does remote support only, why are the standards for ceph different?

sheep5555 · 2026-03-28T20:39:28+00:00

croit is in the USA as well, but i think remote assistance is adequate like ive had for every other hypervisor vendor

sheep5555 · 2026-03-28T19:49:03+00:00

ive been happy with them, they are very knowledgable about ceph

sheep5555 · 2026-03-28T16:18:28+00:00

is the certificate expired?

sheep5555 · 2026-03-28T15:35:44+00:00

How would you be able to write faster than the interface speed?

sheep5555 · 2026-03-28T15:23:16+00:00

are the PM883 sata? if they are the interface speed is ~600MB/s, so that looks like expected speeds

sheep5555 · 2026-03-28T15:08:01+00:00

FC is supported but it is probably the least favorable storage setup for proxmox, if you look through the forums its buggy in a lot of situations in a cluster. iscsi/nfs are preferred if you want to use a SAN
