Hi there, My test host has 2 GbE nics bonded together through 802.3ad, and the switch is configured in a way that the bonded ports can access untagged default vlan and some tagged vlans (10,20,30) for different purposes. Coming from ESXi, I'm quite confused on how to deal with VLANs with...

Hello everybody, I'm planning a new proxmox installation and I'm puzzled whether to use openvswitch or not. So here are some questions, hoping you will help me in choosing: 1) What are the pro/cons of using openvswitch against a standard linux bridge? 2) I just found this...

Really no one? :( AFAIK, that is a fork of MooseFS... Before I'd start playing with it, I would like to know if someone has ever used it with proxmox (or whatever) and how it performs.

Thanks for the replies. I contacted Dell support to ask which controllers are shipped with their poweredge R730 servers, and they are: - H330 (LSI SAS3008) - H730 (LSI SAS3108 w/ 1GB cache) - H730P (LSI SAS3108 w/ 2GB cache) Since Dell doesn't ship HBAs but just RAID controllers with their...

Hello everybody, has anyone already tried LizardFS (http://www.lizardfs.com) as an alternative distributed filesystem? It looks promising and, at a first glance, less complex than ceph since seems that it could be employed on just two nodes. I'm just wondering if it could be coupled with ZFS...

@Nemesiz: so do you definitely recommend ZFS with plenty of RAM over an hardware RAID ?

Hello, we're evaluating Proxmox VE 3.4 and its performance. We'd like to know what are the pro and cons about having a proxmox host with an hardware RAID controller (with its own cache) against using ZFS software RAID with ZIL and L2ARC cache. Are these two solutions comparable in terms of...

What about use some imaging tool (eg. Acronis) on the hypervisor? Restoring a virtual machine from a backup should be easy as replacing its own disk file, isn't it?

@pixel: which are the requirements of the monitor node? I mean, does it need to be powerful as the others running proxmox? And there's the need to have the same amount of disks in there as well? (I was just wondering if I could use some old machine for that)

Hello everybody, I would like to know how do you handle incremental backups of your VMs. With VMware we use to install a dedicated VM which handles hot incremental backups overnight using CBT and writing everything on a NAS, so there's no agent installed individually on each VM. Is there any...

Hello, thank you for the replies. Most of my customers have just one VMware ESXi node so the idea behind was to bring the cluster-power to those small enviroments (where the purchase of SAN is not an option) by employing open source technologies and keeping costs as lower as possibile. I...

Hello everybody, we're evaluating Proxmox VE as a VMware ESXi replacement, and we'd like uo understand if, in a HA environment, a physical SAN/NAS is REALLY required. Several commercial KVM-based projects found on the internet, use some storage replication techniques (so-called Virtual SAN)...
