Publication number: 20160328348Abstract: This invention provides a computer that, on the basis of identifying information for virtual ports for virtual machines in logical partitions, allows per-virtual-machine access control for storage systems. Said computer, which connects to said storage systems, has the following: hardware resources including processors, physical memory, and an I/O adapter; and a first hypervisor that logically divides said hardware resources into one or more logical partitions. Upon receiving an instruction to issue an I/O command to a logical unit of a storage system from a first virtual machine in a first logical partition, the I/O adapter transmits, to said storage system, an I/O command containing first identifying information that identifies a first virtual port for the first virtual machine.Type: ApplicationFiled: January 29, 2014Publication date: November 10, 2016Applicant: HITACHI, LTD.Inventors: Tooru IBA, Yoshihiro TOYOHARA, Naoki KUBOTA, Tetsuhiro GOTOU
