Abstract:
A method of configuring a volume set in a distributed multi-processing system comprising a plurality of compute nodes communicatively coupled to a plurality of input/output (I/O) nodes, each having storage space, the method comprising the steps of:querying the I/O nodes to determine available storage space blocks at each I/O node;displaying information representing the available storage space blocks at each I/O node to a user, the information comprising a storage space block identification and a storage space block size;accepting a volume set name and a selected volume set size not greater than the largest storage space block size;scanning the information to determine if the storage space block size of an available storage space block substantially equals the selected volume set size;selecting an available storage space block for the volume set such that the available storage space block has a size equal to the selected volume set size; andobtaining performance data for the available storage space blocks having a size larger than the selected volume set size and selecting an available storage space block for the volume set based on the performance data, when there is no available storage space block having a size equal to the selected volume set size.
