ISR Disk Performance with Xen and iSCSI

Internet Suspend/Resume currently uses VMware, a proprietary product,
for its machine virtualization. Switching to an open-source
virtualization solution, like Xen, would allow greater
flexibility. This paper intends to examine the feasibility of porting
one portion, the virtualized disk. For modularity, the cache manager
will reside in a separate virtual machine and communicate to Xen
through iSCSI.

We intend to evaluate the disk performance of this approach in order
to inform further development of ISR with Xen.
