Dear All, I have a probably stupid question.... I have some virtual machine gived by Xen. Virtualized O.S. run in a phisical disk. All work fine but I want make this system scalable. GlusterFs appear very perfect for me! Now, I want create storage system as a repository for Xen image files, and use GlusterFS with AFR Image files used for virtualized O.S. have minimum 10Gb files size. I does not have a very cleaned idea of how AFR work.... ....and my question are if this configuration are optimal for this use. Or, in case my idea is poor, where are a optimal configuration for my case? Many thanks, Enrico
