Solaris Multiplexed I/O (MPxIO), known also as Sun StorageTek Traffic Manager (SSTM, earlier Sun StorEdge Traffic Manager), is multipath I/O software for Solaris/illumos. It enables a storage device to be accessed through multiple host controller interfaces from a single operating system instance. The MPxIO architecture helps protect against I/O outages due to I/O controller failures. Should one I/O controller fail, MPxIO automatically switches to an alternate controller. This architecture also increases I/O performance by load balancing across multiple I/O channels. It was integrated within the Solaris operating system beginning in February 2000 with Solaris 8 release. The file to enable or disable mpxio has been moved in Solaris 10 from ''/kernel/drv/scsi_vhci.conf'' to the bottom of the file ''/kernel/drv/fp.conf'' and ''/kernel/drv/mpt.conf''. ==See also== * Multipath I/O * stmsboot command line utility 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solaris Multiplexed I/O」の詳細全文を読む スポンサード リンク
