A hybrid gas generator comprises a chamber that contains pressurized fluid and that is sealed off by a rupturable membrane, and a pyrotechnical propellant charge that ruptures the membrane when it is ignited. The CPU is provided with a CKD record access library and a VSAM access library which accesses in a FBA format the VSAM record stored by the other CPU in a CKD format in the disk subsystem and allows the access by an application program of the CPU as a VSAM record based on VSAM control information. Alternatively, instead of computing the fair share data rate, the network node may receive the fair share data rate which was computed by another network node. Furthermore, the cloud construction block contains modular pieces of hardware, such as compute hardware, memory hardware, storage hardware and network hardware, that are integrated with management software configured to manage both the hardware and the cloud computing environment in a seamlessly integrated package.
