okay, which raid controller do you prefer? it should be fast, not to expensive and should give me good overall performance.

IMPORTANT: Do not use zfs on top of hardware controller which has it's own cache management. Zfs needs to directly communicate with disks, an HBA adapter is the way to go (or something like LSI controller flashed in 'IT' mode) I don't think soo macday, because the our requirements seems to be...

god damn, i finaly found the problem. It's not proxmox related. It's because we are mixing Windows 7 and Windows 8 Maschines. Windows 7 is using SMB V2 and Windows 8 and Windows Server 2012 R2 are using SMB V3 plus and a security feature against spoofing is killing the traffic ...

Bullshit! The Setup was correct all the time. I'm using three different types of proxmox servers, in different areas, since more than a year. Never had any problem. Everything worked. That's why i put so much energy in this project. At this point it's not my task anymore to figure it out. It's...

As soon as possible i try the vm directly on the server, and if it works.... the whole proxmox thing is done for me on this machine....

Yesterday was a hard day. I worked 15 hours. First i made a clonezilla image of my virtual server. Installed it on bare metall, it worked but then i saw an eventually loop, so i changed cabling of the server. Saw a chance that this could be the reason why proxmox guest clients(WSrv2012) had...

I will try something new today, before i finally move over to bare metall. Because WINS is used on the clients to address the server, we will change it to the server ip. Maybe WINS is causing problems on a virtual machine on proxmox with the network stack and maybe this is a workround - i don't...

Today i started a last test, because i have to move the server to bare metal. Test: Copy a huge file from the old server(wm2008,physical) to the new server (wm2012,proxmox) and vice versa. It worked. And the graph worked right too. I'm a little bit clueless why we always struggle if i change...

I wanna stay on proxmox, because i simply love it. Jesus what guest PC's are they Windows Server Machines? I'm asking myself if the error would occur if i you windows server 2008 instead of 2012. Other solution could be to run our server on a linux maschine until the windows server problem is...

oh my god, my boss would kill me :D but how do we solve this network issues .... is there a work around?

We bought a 3500€ server. I told them i will use proxmox, because of the great features and now i'm screwed, because we are using still our old bare metal server.

Any news?

I mean 100 Megabyte / second - round about 1gbit. But the network graph shoes very low values. it falls down from 100mbyte/gbit to zero .... And i don't have any explanation

I don't understand the stats of proxmox. Because i was sending 100mb/s via the windows guest server and a physical machine. But the stats does not point it out. Do you have any other ideas why this network drop could happen?

Okay, i will reproduce it but i can't do it right now. But here i can give you the screenshots from my last test:

I tried different Styles on the Windows VM. Two vNics, one vNic. E1000 or Virtio. No Changes. I can't say anything to cpu usage and IO delay, only one thing: Every time the network speed went down like you see in the screenshot, the maschine was fully usable without any problems. The Proxmox...

Hello, on our proxmox server we notice strange network behavior. The network rate drops on our windows server 2012 guest. Every client notices a break. On the windows server guest there is a programm running for doctors office software. Everytime the network bandwidth is shaking from...
