Hi All -

I am new to this board, and new to what I am doing do forgive my ignorance. I have an R710 server with 6 HDDs, and I have setup the machine up with three RAID 0s - strip 0, 1 and 2. I have done this as we use RAID 0 in our daily work for speed, and what my intent here is to use my R710 as 3 machines, spinning up virtual machines on each of the three RAIDs and running what I need. Knowing this, do I need to install Proxmox on each strip that I have setup, with three separate IPs OR do I setup 1 instance proxmox on strip 0 and am I able to point to which strip I want to use for that virtual machine??

Secondly, my virtual machines will be using Windows server 2003 and is it possible to partition a virtual machine? In our work, we need to have multiple drives...C:, D:, etc. on our machines, and I have not found a way to partition a virtual machine or if it is even feasible.

Again, I am new to this, so please be gentle :)

Thanks for any and all assistance you are able to provide.

Hi,
the advantage of virtualization is to offer many VMs... so you don't need install PVE on multible raidsets.
Simple install PVE on the first raidvolume (a small (50G) one is enough). Create on the other volumes volume-groups and define this in the storage-menue.

Then you can select for each VM (and disk), on which storage the data is.

But you should use raid-10 instead of raid-0!! If one disk die, you know why.

I do fully understand the limitations of running in a RAID 0 environment, all too well. But that is what is needed for our particular setup.

Thanks for the knowledge, it will help in getting this server setup properly!
 
Udo -

not sure I know how to setup a volume group on the other RAID sets. Initially when I setup the RAIDs, I went into the BIOS and setup three RAID 0, each with about 900GB in space, gave them all unique names, etc. When I attempt to find them in proxmox and create storage it is not seeing anything. Should I have setup one RAID 0 to load proxmox on, and then create the other RAIDs from there, then being able to setup the storage from within proxmox? I am new to this, so forgive my question.

Thanks!
 
again, do not use raid0, never.

so before you go further, configure a suitable raid level, e.g. raid10.

Again, I understand what you are saying and the consequences of a RAID 0, but for our purposes we use RAID 0.

Again, I understand your concerns, but for our purposes we need the speed RAID 0 brings and it is not about the data integrity. I appreciate the response.
