What are the pros and cons to file virtualization appliances? Which do you think is better and why?
Once file virtualization is implemented, you should also be able to enable or disable it without disruption. Suppose you don't want it running during daytime mission-critical production workloads -- you might prefer to run virtualization at night for back-end operational tasks. Determine the amount of disruption involved in removing the virtualization layer.
While a particular vendor's software will control the file virtualization, it is proprietary (vendor-specific) hardware that can potentially cause the most disruption. You want to reduce the "stickiness" of a virtualization platform, minimizing the vendor lock-in for both software and hardware.
