The safety breaker also prevents power surges in the AC line from damaging a system. The controller node that takes over for the virtual volume backup node if the virtual volume node fails. Connection between a controller node initiator port and a physical disk that is used when the primary path is inaccessible (a failure condition). The primary and secondary paths are not user-configurable; they are determined by drive magazine placement. A self-encrypting drive (SED) uses Advanced Encryption Standard keys to protect data from unauthorized access. SEDs contain special firmware and an application-specific integrated circuit (ASIC) that provides encryption. When encryption is enabled, the SED will lock when power is removed, and it will not be unlocked until the matching key from the HP 3PAR StoreServ system is used to unlock it. A device inserted into a rack or virtual software that enables you to locally and remotely monitor and service systems. The number of chunklets in a set. Also known as mirror depth for RAID 1 sets and parity set for RAID 5 sets. Icon in the HP 3PAR Management Console alert pane or on the HP 3PAR Management Console status bar that shows the seriousness of an alert. Small form-factor pluggable transceiver. A virtual or physical copy of a virtual volume. The space on a virtual volume that is used to track changes to the data from the time that a snapshot of a virtual volume was created. The virtual volume from which a copy is made. A chunklet that is reserved for use in case of a failure in the system. A certain number of chunklets are reserved for use as spares during the system setup and installation process; however, the system may temporarily set aside additional spares even though these chunklets are not permanently designated for use as spares. Indicates whether a chunklet is reserved as a spare or has been selected by the system for use in sparing on a temporary basis. The automatic relocation of chunklets on a physical disk when a logging logical disk becomes full. Service Processor Onsite Customer Care. A suite of service tools applications with a web-based graphical user interface that is used to support the HP 3PAR storage system and its Service Processor. Single Point of Connectivity Knowledge website. SPOCK is the primary portal used to obtain detailed information about supported HP storage product configurations. Snapshot data that is no longer valid because the base volume does not have enough snapshot administration or snapshot data space to record new changes to the base volume. A snapshot that does not track the most recent changes to its base volume. The No Stale Snapshots virtual copy policy halts writing data to the base volume in order to prevent loss of synchronization between the volume and any snapshots. A virtual volume that either passed auto-check upon system startup or was created since the system was last restarted. Started virtual volumes are ready for read/write operations. The bar at the bottom of the HP 3PAR Management Console main window that contains messages and icons. Status bar messages and icons can provide vital information about system status, including the severity level of the most serious new alert in the alert pane. The number of contiguous bytes that the system accesses before moving to the next chunklet. A virtual volume that has not been started and is therefore not ready for read/write operations. 91
