[Xen-users] disk access besk practice

[Brian Krusic <brian@xxxxxxxxxx>]

Hi all,

While I've read some faqs, forums and Professional Xen Virtualization,  
I would like your take on this.
I've 2 paravirtualized domUs running, each using tap:aio disk image  
located on a local 500GB raid.
While performance seems fine both interactively and using benchmarks,  
is there a practical limit to the image size before I should start  
breaking it up?
I plan to build another dom0 box with a 24TB raid on it and hosting 2  
paravirtualized domUs, one of which will need 20TB.
Should I break up the domU into 2 images, 1 for the OS and the other  
for storage needs?
So my questions are;

1 - Whats a practical single disk image size?
2 - Should I pre allocate all image space during domU creation or have  
it dynamically grow?
- Brian
