Abstract: Described are methods, systems, and apparatus, including computer program products for maintaining computer systems in compliance with best practices. A configuration data set is received specifying a plurality of operational parameters, and, for each operational parameter, a target setting for the operational parameter. For each operational parameter of the plurality of operational parameters: a computer system is queried for a current setting of the operational parameter on the computer system; it is determined whether the current setting of the operational parameter complies with the target setting for the operational parameter; and a command is sent to the computer system to change the current setting of the operational parameter on the computer system to conform with the target setting for the operational parameter.

Abstract: A method is used in reserving storage space in data storage systems. A set of logical units (LUs) predefined as file based storage hardware specific LUs are reserved in a restricted access storage space of a block based storage system. The restricted access storage space is accessed by a file based storage system for storing information required for initializing the file based storage system. The file based storage system is initialized using the information stored in the file based storage hardware specific LUs.

Abstract: A method for adding file based storage hardware to a block based storage system includes detecting, by the file based storage hardware, an electrical coupling between the file based storage hardware and the block based storage system, the block based storage system having a set of logical units (LUs) predefined as file based storage hardware specific LUs. The method includes forwarding, by the file based storage hardware, an initiator record to the block based storage system, the initiator record configured to control access by the file based storage hardware to data stored by the block based storage system and the initiator record having a file based storage hardware specific identifier. The method includes, following the block based storage system associating the initiator record having the file based storage hardware specific identifier with the predefined file based storage hardware specific LUs, establishing a communication path with the block based storage system.
