mirroring The process of providing complete data redundancy with two physical disks by maintaining an exact copy of one disk's data on the second physical disk. If one physical disk fails, the contents of the other physical disk can be used to maintain the integrity of the system and to rebuild the failed physical disk. Name A virtual disk property indicating the user-assigned name of the virtual disk. non-redundant configuration A non-redundant configuration is a RAID 0 virtual disk with data striped across two or more physical disks, but without disk mirroring or parity. This provides for high data throughput but offers no protection in case of a physical disk failure. NVRAM Acronym for non-volatile random access memory. A storage system that does not lose the data stored on it when power is removed. NVRAM is used to store firmware and configuration data on the RAID controller. NVRAM Present A controller property indicating whether an NVRAM is present on the controller. NVRAM Size A controller property indicating the size of the controller's NVRAM. offline A physical disk is offline when it is part of a virtual disk but its data is not accessible to the virtual disk. patrol read A process that checks the physical disks in a storage configuration for physical disk errors that could lead to drive failure and lost data. The patrol read operation can find and sometimes fix any potential problem with physical disks prior to host access. This enhances overall system performance because error recovery during a normal I/O operation might not be necessary. Glossary 85
