Abstract
A method and data storage system using the method, provides an efficiently approach for allocating a static amount of buffer space (e.g., records) among a number of logical volumes of a data storage system on the basis of the computing environment within which the data storage system is used. The method includes providing the data storage system from logical volumes, each including a command queue. Each command queue includes records, each for storing a command request. A memory pool is established from which one or more records can be allocated to each command queue associated with each logical volume. The memory pool has a predetermined number of records which can be allocated by the command queues of the logical volumes. Based on the computing environment, one of a number of allocation schemes for allocating records to a command queue is selected.
