    "I recently learned something about NASes that buyers looking to use these products for database and other simultaneous-file-access applications should know about. The issue is how Opportunistic Locking ("oplocks") are handled." "Opportunistic locks (oplocks) are a characteristic of theLAN Manager networking protocol implemented in the 32-Bit Windows family of operating system environments. Bascially, oplocks are guarantees made by a server for a shared logical volume to its clients. These guarantees inform the Client that a file's content will not be allowed to be changed by the server, or if some change is imminent, the client will be notified before the change is allowed to proceed."
