The system according to claim 1, wherein said characteristic of said cooling fluid comprises at least one of volume flow rate, velocity and direction of cooling fluid removal. 3. The system according to claim 1, further comprising:at least one return controller operable to control at least one of said returns, wherein said at least one return controller is configured to substantially independently control said returns to thereby substantially independently vary said characteristic of said cooling fluid removal. 4. The system according to claim 3, further comprising:a plurality of sensors configured to sense an environmental condition within said data center, said environmental condition including at least one of temperature, humidity, pressure, and cooling fluid flow rate, wherein said at least one return controller is configured to substantially independently control said returns in response to said measured environmental condition. 5. The system according to claim 4, wherein said plurality of sensors are configured to sense an environmental condition in locations outside of the plurality of racks and wherein the at least one controller is configured to substantially independently control said plurality of returns in response to said measured environmental condition out side of the racks. 6. The system according to claim 1, wherein said vent controller is operable to substantially independently control said vents in response to at least one of said returns being varied. 7. The system according to claim 1, wherein the plurality of returns includes fans configured to draw cooling fluid from the data center, wherein the fans are movable to vary a direction of cooling fluid removal. 8. The system according to claim 1, wherein the characteristic of said supply of cooling fluid comprises at least one of volume flow rate, velocity and direction of cooling fluid supply. 9. A method of cooling a plurality of racks in a data center having a lowered ceiling, said method comprising:activating a cooling system and opening a plurality of returns positioned at various locations along the lowered ceiling, said returns being configured to remove cooling fluid from various locations of said data center;opening a plurality of vents configured to supply the racks with cooling fluid;sensing the temperatures of said racks;determining whether said sensed temperatures are within a predetermined temperature range;varying said removal of said cooling fluid from said racks in response to said sensed temperatures being outside said predetermined temperature range; andvarying a characteristic of cooling fluid flow through one or more of said plurality of vents in response to the sensed temperatures being outside said predetermined temperature range. 10. The method according to claim 9, wherein the step of varying said removal of said cooling fluid from said racks comprises varying the direction of removal of said cooling fluid. 11. The method according to claim 9, wherein the step of varying a characteristic of said cooling fluid flow through one or more of said plurality of vents comprises varying at least one of volume flow rate, velocity and direction of cooling fluid supply. 12. The method according to claim 9, wherein the step of varying said removal of said cooling fluid from said racks comprises substantially independently controlling said plurality of returns to thereby substantially independently vary said removal of said cooling fluid from said racks through said plurality of returns. 13. The method according to claim 9, wherein the step of varying a characteristic of said cooling fluid flow through one or more of the vents comprises substantially independently controlling said plurality of vents to thereby substantially independently vary said supply of said cooling fluid to said racks through said plurality of vents. 14. An apparatus for cooling a plurality of racks in a data center having a lowered ceiling, said apparatus comprising:means for activating a cooling system and opening a plurality of returns positioned at various locations along the lowered ceiling, each of said returns being configured to remove cooling fluid from various locations of said data center;means for opening a plurality of vents configured to supply the racks with cooling fluid;means for sensing the temperatures of said racks;means for determining whether said sensed temperatures are within a predetermined temperature range;means for varying said removal of said cooling fluid from said racks in response to said sensed temperatures being outside said predetermined temperature range; andmeans for varying a characteristic of cooling fluid flow through one or more of said plurality of vents in response to the sensed temperatures being outside said predetermined temperature range. 15. The apparatus according to claim 14, wherein the various locations of said data center comprises a plurality of racks. 16. The apparatus according to claim 14, wherein the means for varying said removal of said cooling fluid from said racks comprises means for varying the direction of said removal of said cooling fluid. 17. The apparatus according to claim 14, wherein the means for varying a characteristic of said cooling fluid flow through one or more of said plurality of vents comprises means for varying at least one of volume flow rate, velocity and direction of cooling fluid supply. 18. The apparatus according to claim 14, wherein the means for varying said removal of said cooling fluid from said racks comprises means for substantially independently controlling said plurality of returns to thereby substantially independently vary said removal of said cooling fluid from said racks through said plurality of returns. 19.
