I came across this interesting blog today showing how you can set up a fairly robust Hyper-V cluster using low-cost laptops and standard iSCSI networking.
The author says his goal is to show that you can add extra availability to Windows environments even if you don't have access to top-tier data center technology. And in the process, he finds out that even a low-bandwidth 100 MBps iSCSI connection can outperform local disk technology.
This particular experiment used a pair of Toshiba Satellite laptops, connected through a Vonage router, a Linksys 4-port hub and a D-Link gigabit switch.
The most remarkable performance result involved the building of a full Windows server, which required just over an hour and some 40 minutes less than when the disk files were on the same hard drives as the host computer.
It's a good read for those of you who like to tinker. And it highlights that iSCSI is a powerful networking technology for virtual environments, even under extremely poor conditions.
