Abstract: An instrument for drilling dental root canals, includes a tapered rod having on at least an active part of its length, at least one helical flute defining at least one helical cutting edge. The instrument also has a helical hollow on a portion of the active part extending as far as the point of the rod. At least one of the edges defined by the helical hollow is coincident with the cutting edge, the hollow reducing the cutting angle of the cutting edge. Any cross-section of the active part has at least one convex side belonging to the helical flute. The closer the cross-section in question is to the point of the rod, the more the curvature at any point of the convex side increases and tends to approximate the curvature of the circumscribed circle of the cross-section and passing via the cutting edge defined by the helical flute.

Abstract: A method for replicating I/O performance in data replication environments, such as PPRC environments, is described. In selected embodiments, such a method includes monitoring I/O workload at a primary storage device over a period of time, such as a period of hours, days, or months. The method then generates learning data at the primary storage device describing the I/O workload over the selected time period. The learning data is replicated from the primary storage device to a secondary storage device. The method uses the learning data to optimize the secondary storage device to handle the I/O workload of the primary storage device. This will enable the secondary storage device to provide substantially the same I/O performance as the primary storage device in the event a failover occurs. A corresponding system and computer program product are also disclosed and claimed herein.
