Ok, that did not directly come to mind to be honest, but it is very understandable at the moment. Our customers when migrating away from Hyper-V or VMware environments usually do this when they need to replace their hardware after 5-8 years. In the case of VMware I do understand, since Broadcom...

I am a little confused by your response so just checking if we are on the same level here... You can set up like for example: PVE01 > Hypervisor, packages for qnetdevice, LINBIT packages, ... PVE02 > Hypervisor, packages for qnetdevice, LINBIT packages, ... PBS01 > Backup (Proxmox backup...

Why don't you look into LINBIT / Linstor (DRBD)? > https://linbit.com/blog/linstor-setup-proxmox-ve-volumes/ It's pretty easy to setup if you need a 2 cluster setup and have small device for quorum, we combine this quorum with Proxmox Backup Server.

Select disk 0 and 1 and click on Create Virtual Disk, and again for disk 2 and 3 (based on slot numbering) You could have 2x RAID 1 (don't mix them). If you have an option somewhere to select where to boot from it will probably be listed as VD0 or something like that, I guess in the other tab...

Well it depends on the exact storage config, I am getting a little confused about your setup because earlier your said you have your disk passthrough directly (i'll read entire post again if i have some more time :)). Example: RAID Controller with a RAID 1 created on it > do not use ZFS. RAID...

I did not yet know about this issue, also did not come across any problems yet, need to check which VirtIO version it is running at customers (they have MS SQL but I think not yet fully updated.) Thanks!

To "squeeze" it out as much as possible: Change SCSI to VirtIO. Seperate your SQL data on separated virtual disks (OS, Data, Log, TempDB) with alignement for SQL Server (8KB pages) And please put your disks in a mirror before going into a production environment.

Ok, but cache=writeback is something you need to be very carefull with. You have your disks passed through directly to ZFS without HBA or RAID controllers which is considered best practice but: In a classic setup with a RAID controller some of them support a Cache Vault (a battery that keeps...

I am not really sure what you mean by this... If you currently have 2x 1.8TB disks (SSD?) and they are already in a zpool (raid1 / mirror) then you do not need to delete everything and start over, what I did was creating a block device (zvol) on an already existing pool with different settings...

You could do a replication setup, minimal replication time could be 1 minute and if you could add a quorum (qnet-device, i do this with Proxmox Backup Server) than in case of a node failure your VM's will automatically start up on your other node. Just to pitch you an idea :)

OK, 320TB raw capacity, you are going to use Ceph with N-replication? leaving a +/- 106TB net capacity if it would be a 3-way replication setup. Back-ups are going offsite? just in case? cause you mention everything in one rack.

Is it going to be exactly like the drawing or is the setup going to be separated across different rooms? You have 8x 8TB, is this per server or in total? that's not entirely clear to me, I am guessing that this per server but just checking :) I am very interested in following your setup and how...

That's not really what i meant you should reverse that to 16K (default) because that's a pool wide setting; I've checked on how to do this because PVE created the virtual disks for you with default 16K setting. I have prepared here an example VM for SQL, virtio0 will be for my OS: You'll want...

In your initial post there is a screenshot of the new server; you are not using VirtIO, I quickly deployed a W2K25 install configured with VirtIO for everything while yours display SSD (SAS) for the disk: I am pretty sure you are using the following settings (this is from my own...

Hi, Very interested in this cause SQL server is used a lot. If I understand your problem correctly; You have an old VMWare server that is faster than your newer server where you are using PVE 9.1? Can you provide specs from both servers; CPU, storage configuration/layout, memory, ... the more...
