Depending on your load and application design, the queued requests may be sufficient to run you out of heap memory, database handles and similar.
I assume your goal is to improve reliability of end-user access to your application. If you have to use Windows, why would you take a DFS approach rather than using Windows' file replication to replicate files to multiple servers? The probability of network failure or poor performance is orders of magnitude higher than the probability of HDD subsystem failure or poor performance, so I would expect accessing apps from a remote network drive to worsen your reliability rather than improve it. - Peter
