Decent read: http://lass.cs.umass.edu/papers/pdf/FAST04.pdf
As far as CS + XenServer, I prefer NFS. Easier to manage, thin provisioning works from the get go (which is super important as XenServer uses CoW (linked clones) iterations from the template you use.) By default, XS uses LVM over iSCSI with iSCSI which can be confusing to administer. That and it doesn't thin provision... which sucks... In theory there are latency penalties with NFS (as mentioned in the paper) but in a live deployment, I never ran into this.
