Technically: yes. However, we strongly recommend you don't. However, if you absolutely really want to, I recommend using NFS instead of iSCSI to share the unused space.
Curious question: Why do you recommend this instead of iSCSI?
Our testing shows that NFS is less likely to cause CPU starvation of the guests.
Well, you can't use an exported local file system (either via iSCSI or NFS) for any of that either. The only way you get failover is via shared storage.
Yes. The idea was to use the local disk space for other (not VM related) services.
The exercise I am going through, satisfying proprietary software, is exactly a demonstration to show the benefits of open software because the later gives you the freedom of choice:-)
Oracle VM Server is Open Source. :)
Yes, more the top to bottom. Sage X3 limits DB support to Microsoft SQL Server or Oracle DB and print support to Crystal Reports and so MS Windows Server, Oracle DB with support limits my OS and virtualization choices etc. If you have a local reseller who panics about everything they did not do before (means everything that's not from Redmond) .. then it's bound to become great;-)
Have fun with your project though. I went through a similar exercise a few years ago.
Thanks, I certainly have. It keeps me busy:-) I have the infrastructure up and running but I am not really happy about my server layout, available and usable disk space, backup, mirroring, performance and administration as the main concerns (this includes more than just than SAGE). At the moment my brain is redesigning every ten minutes using all tools like Lego .. but none of the solutions make me really happy. Cheers Peter
