wherein said storage management engine is further capable of retrieving first memory units at said first determined information retrieval rate from said at least one storage device, and storing said first memory units in said buffer/cache memory, and retrieving second memory units at said second determined information retrieval rate from said at least one storage device, and storing said second memory units in said buffer/cache memory; and

wherein said storage management processing engine is further capable of delivering said first retrieved memory units from said buffer/cache memory to said second processing engine for delivery across said network to said first user, and delivering said second retrieved memory units from said buffer/cache memory to said second processing engine for delivery across said network to said second user.

97. The system of claim 96, wherein said first determined information retrieval rate is based at least in part on said first monitored information delivery rate using a first information retrieval relationship;

wherein said second determined information retrieval rate is based at least in part on said second monitored information delivery rate using a second information retrieval relationship; and

wherein said first information retrieval relationship differs from said second information retrieval relationship.

98. The system of claim 96, wherein said first information retrieval relationship differs from said second information retrieval relationship based at least in part on one or more priority-indicative parameters associated with at least one of a request for said information received from said first or second users;

one or more priority-indicative parameters associated with at least one user requesting said delivery of said information, or a combination thereof.

99. The system of claim 96, wherein said first information retrieval relationship differs from said second information retrieval relationship based at least in part on one or more class identification parameters, one or more system performance parameters, or a combination thereof.

100. The system of claim 90, wherein said information management system comprises an endpoint content delivery system;

and wherein said data object comprises continuous streaming media data.

89. A network-connectable information management system, comprising:

at least one storage device;

a first processing engine comprising a storage management processing engine coupled to said at least one storage device;

a buffer/cache memory;

a network interface connection to couple said information management system to a network; and

a second processing engine coupled between said first processing engine and said network interface connection;

wherein said storage management processing engine is capable of determining an information retrieval rate for retrieving information from said storage device and storing said information in said buffer/cache memory, said information retrieval rate being determined based at least in part on a monitored information delivery rate from said second processing engine to a user across said network that is communicated to said storage management processing engine from said second processing engine.
