Abstract: A method, computer program product and system enabling provisioning of a storage volume across network resources through the storage provisioning interface, wherein the storage provisioning interface enables provisioning of network resources to enable presentation of a provisioned storage volume, wherein the provisioned storage volume is enabled to be provisioned across a plurality of storage resources across the network resources, and wherein the provisioned storage volume is enabled to be a redundant distributed volume.

Abstract: Methods and apparatus to provide command abstraction. In one embodiment, a method includes obtaining information on commands for a plurality of devices including devices of the same type having different command structures, receiving a generic command from a user directed to one of the devices of the same type, determining, using a computer processor, whether the generic command is supported, extracting parameters from the generic command, and generating from the extracted parameters and the generic command a device-specific command for execution by the one of the devices of the same type.

Abstract: Seamless steel tubes suitable for use as grades of casing and line pipe having yield strengths in excess of 70,000 psi, without being heat treated, are made of an alloy comprising, by weight, about 0.10% to 0.18% carbon, about 1.0% to 2.0% manganese, about 0.10% to 0.16% vanadium, about 0.008% to 0.012% titanium and about 150 parts per million to 220 parts per million nitrogen, the balance comprising iron and incidental impurities. Strains are applied to the shell in a stretch reducing mill below the T.sub.nr of the steel and above the A.sub.r3 to provoke dynamic recrystallization. The nitrogen and vanadium are preferably introduced to the steel during alloying in the form of a VN alloying agent. The vanadium, titanium and nitrogen are predominantly present as vanadium nitride and titanium nitride. The steel may also comprise 0.03% to 0.05% aluminum by weight.

Abstract: A method for producing seamless steel tubes suitable for use as grades of casing and line pipe having yield strengths in excess of 70,000 psi, without being heat treated. Such steels are made of an alloy comprising, by weight, about 0.10% to 0.18% carbon, about 0.10% to 2.0% manganese, about 0.10% to 0.16% vanadium, about 0.008% to 0.012% titanium and about 150 parts per million to 220 parts per million nitrogen, the balance comprising iron and incidental impurities. The subject method comprises the steps of alloying a steel of the aforesaid chemical composition, forming the steel into a billet of steel, reheating the billet in a reheating furnace, passing the billet through a piercing mill to form a steel shell, elongating the steel shell within a mandrel mill, and reducing the diameter of the elongated shell in a stretch reducing mill. Strains are applied to the shell in the stretch reducing mill below the T.sub.nr of the steel and above the A.sub.r3 to provoke dynamic recrystallization.
