Prism Storage Architecture
TM
Accommodates a wide range of needs
from large data centers to work groups to remote sites and is based on the
PCI bus. Scalable Prism options provide “plug and play” serviceability,
eliminating expensive upgrades and library obsolescence. It improves
manageability with library partitioning, SNMP integration, e-mail
notification, and Web-based management features.
R
RAID Redundant Array of Independent Disks is a technology through
which several physical storage disks are grouped into an array that
appears to an operating system as one or more physical devices.
Reports Refers to the report options on the touch screen GUI’s Service
screen.
Robotics As used in the context of automated tape libraries; the X-axis,
Y-axis, and Z-axis mechanical assemblies inside the library used to move
tape cartridges.
RS-232C Short for Recommended Standard-232C, a standard interface
approved by the Electronic Industries Association (EIA) for connecting
serial devices. This standard is for ASYNCHRO-NOUS TRANSFER
between computer equipment and accessories. Data is transmitted bit by
bit in a serial fashion. The RS-232 standard defines the function and use of
all 25 pins of a DB-25 type connector.
S
SCSI Small Computer System Interface. An American National
Standards Institute (ANSI) communications standard for attaching
peripheral equipment to computers.
SCSI ID A unique address (0 to 15) assigned to each device on a SCSI
bus.
SCSI-2 A second generation SCSI interface which includes command
sets for magnetic and optical disks, tapes, printers, processors, CD-ROMs,
scanners, medium changers, and communication devices.
SCSI-3 A very fast version of SCSI which can have an 8-bit or 16-bit
bus.The 8-bit version has a 50-pin adapter, transfers data at a rate of 20
megabytes per second, and can connect a maximum of 8 devices.The 16-
bit version has a 68-pin adapter, transfers data at 20 to 40 megabytes per
second, and can connect up to 16 devices.
SDLT Super Digital Linear Tape is a Quantum tape drive and tape
cartridge specification offered in three ranges of capacity and transfer
rates for workgroup, mid-range, and enterprise needs.
