IBM researcher: Marc Auslander
Where the work was done: IBM T.J. Watson Research Center
What we accomplished: Adapted from Wikipedia: "Logical volume management (LVM) provides a method of allocating space on mass-storage devices that is more flexible than conventional partitioning schemes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions (or block devices in general) into larger virtual ones that administrators can resize or move, potentially without interrupting system use."
