PRESERVING DATA AVAILABILITY AND I/O PERFORMANCE WHEN CREATING VIRTUAL RAID VOLUMES |
摘要 |
A method for preserving data availability and I/O performance when creating a virtual RAID volume includes exposing a set of backend virtual volumes. The backend virtual volumes are implemented on a set of physical storage devices (e.g., physical disks or solid state drives) residing on a storage system. The method further enables selection of the set of backend virtual volumes to create a virtual RAID volume having a selected RAID level. The method further provides verification that the backend virtual volumes will be implemented on the physical storage devices in a way that preserves the data availability and I/O performance associated with the selected RAID level. A corresponding computer program product and apparatus are also described.
