REAL TIME MEASUREMENT OF VIRTUALIZATION I/O PROCESSING DELAYS |
摘要 |
A computer system includes memory divided into a plurality of logical partitions (LPARs), each LPAR running one of a plurality of instances of an operating system (O/S). The system also includes a processor configured to run a hypervisor program to manage operation of the plurality of LPARs. The processor determines a reference I/O service time of an I/O operation on a server, measures an actual I/O service time of the operation, and determines a delay time of virtualization on the server based on the reference I/O service time and the actual I/O service time. |
