Glossary |
Runs in the background on your system, monitoring and managing event notifications, tasks schedules, and other on-going processes in your storage space. It requires no user intervention and includes no user interface.
Space on a disk drive that is not being used by a logical drive. When a logical drive is deleted, its space becomes available.
A HBA function that continually and automatically verifies your logical drives once they’re in use.
Any path used for the transfer of data and the control of information between disk drives and a RAID HBA.
RAID HBA feature that allows data that has been moved to a hot-spare to be returned to its original location once the controller detects that the failed drive has been replaced.
Direct-attached Storage. Data storage that is physically connected to a server.
Another name for a RAID 6 or RAID 60 logical drive.
A utility within the Sun StorageTek RAID Manager software that emails event messages to selected recipients.
Event messages about remote systems that are emailed to selected recipients.
Activity on your storage space, such as a disk drive failure or logical drive verification.
The ability of a system to continue to perform its functions even when one or more disk drives have failed.
A combination of hardware and software; software written onto read-only memory (ROM).
A hardware device that interprets signals between a host and a disk drive. Also known as an adapter or card.
A system that’s connected to a TCP/IP network.
An adapter card that includes all of the I/O logic, software, and processing to manage the transfer of information between the host and the devices it’s connected to.
A spare disk drive which will automatically replace a failed disk drive in a logical drive.
Remove and replace a failed disk drive in a logical drive without shutting down the server or disrupting activity on the logical drive.
Prepare a disk drive for reading and writing.
Input/Output. Data entering into or being extracted from a system.
Local Area Network. A network of interconnected workstations sharing the resources of a single server, typically within the area of a small office building.
Light-Emitting Diode. An electronic device that lights up when powered.
The computer (or system) that you’re working on. In the Sun StorageTek RAID Manager software, ‘local’ and ‘remote’ are relative terms.
Event messages about remote systems that appear in the Event Viewer of the Sun StorageTek RAID Manager software.
One or more disk drives grouped together to appear as a single device to an operating system. Also known as a logical device or array.
A computer (or system) in a storage space that’s being managed by the Sun StorageTek RAID Manager software.
MegaByte. Depending on context, 1,000,000 or 1,048,576 bytes. Also 1000 KB.
Data protection that duplicates all data from one drive onto a second drive.
A utility within the Sun StorageTek RAID Manager software that broadcasts event messages to selected managed systems.
A form of data protection used by some RAID levels to re-create the data of a failed disk drive in a logical drive.
Divides the space of a disk drive into isolated sections.
A connection point to a disk drive, expander, enclosure, or other device.
Redundant Array of Independent Disks. For more information on RAID and all supported RAID levels, see Selecting the Best RAID Level.
The trail of yellow or red warning icons that leads from the high-level system view to the failed or failing component.
Re-create a logical drive after a disk drive failure.
A scheduled task, such as logical drive verification, that occurs on a regular basis.
The capability of preventing data loss if a disk drive fails.
In the Sun StorageTek RAID Manager software, all other systems in your storage space besides your local system are remote systems. ‘Local’ and ‘remote’ are relative terms.
A program that updates the BIOS and firmware codes on the HBA.
Storage Area Network. A storage architecture that connects servers and disk drives across a network for enhanced reliability, scalability, and performance.
Activity, such as logical drive verification, that is set to be completed at a specified date and time.
Disk drive space that has been assigned to a logical drive. A segment can include all or just a portion of a disk drive’s space.
Simple Mail Transfer Protocol.
The HBA(s) and disk drives being managed with the Sun StorageTek RAID Manager software.
Amount of data written to one partition before the HBA moves to the next partition in a stripe set.
A RAID 1 Enhanced, or RAID 1E, logical drive.
A method of enhancing performance by spreading data evenly over multiple disk drives. Provides no data protection.
A utility in the Sun StorageTek RAID Manager software that allows you to schedule a specific activity, such as expanding a logical drive, for a time that’s convenient.
TeraByte. Approximately one million-million bytes, or 1024 GB.
Transmission Control Protocol/Internet Protocol. A set of communication protocols used to connect hosts on the Internet.
Check a logical drive for inconsistent or bad data. May also fix any data problems or parity errors.
