Proxmox with Storage Server

[Luis Pesaressi]

Hi, I want install Proxmox (3 Nodes HP Proliant ) and add a storage server (hp storage 2000), I read configuration with 3 nodes with internal disk for proxmos and 1 more disk for HA, but I can´t view any configuration with storage server, some body know how can make this configuration for more "HA" or more fast recovery VM

thanks

Luis

Where did you read this? It sounds a bit weird to me.

The way to go with a central storage is to export the storage as either iSCSI or NFS. See our documentation for supported storage types.

If you do this use a separate physical network to connect to the storage to avoid problems. The storage traffic an saturate the network quite easily and block other services that need to use it.

Hi Aaron Thank for you answer, well I read in all forum than configure Proxmox in a server (node) in a one disk and other disk (each node) for HA, all samples have this configuración 1 disk for proxmox a 1 disk for VM (HA), but I new using Proxmox and I would like intall proxmox with raid 1 in each server (node) and VM in my storage server , server connected to storage for Fiber, my question is : this configuration is possible ??, for mor fast recovery the VM...??

Thanks
Luis

Yes using a central storage server for the VMs is possible. Use either iSCSI or NFS to export the storage to the Proxmox servers.
Please check our documentation for more details.

server connected to storage for Fiber

Fiber ethernet or channel?

Fiber ethernet or channel?

MY 3 server is connected with SAS channel

MY 3 server is connected with SAS channel

You have 3 SAS channels on your san? No idea how that can be configured.

I used an MSA60 directly on a RAID card on one system and all disks appear directly.

Hi,
i am a bit confused, i myself have an MSA2040 unit which has 4 SAS ports , connected to 4 separate servers, and configured for shared access of the LUN's i have configured.

as far as i can derive from your info :

• You have 3 server
• you have a MSA2000
• It is physically connected to ONE server over SAS (server 3) ?

please elaborate ?

OCFS2, you need build OCFS2 cluster on Proxmox.

1. Build OCFS2 cluster ( it is very very basci )
2. Mount OCFS2 folder on all host with same folder name like /mnt/SANSTORAGE
3. add that folder to data storage also select shared folder. Then all host can access to that storage area at same time..

* OCFS2 system not have compression feature because of that Linux will wirte to "0" to disk...

But if that SAS device can not share same stora area for all host and give diffrent partition to each one; you can make with GlusterFS. I get neerly same IO and BW with Ceph from GlusterFS via ZFS backend also GlusterFS can compression via ZFS because of that I can manage many guest in very little storage area
