Features and Benefits of HSG80 ACS 8.6P Data Replication Manager

Features and Benefits of HSG80 ACS 8.6P Data Replication Manager 22
Quality of Service (QoS)—Each virtual connection in an ATM network has a service category.
The performance of the connection is measured by the established QoS parameter, which is
outlined by the ATM forum.
Small Computer System Interface (SCSI)—An American National Standards Institute (ANSI)
interface standard defining the physical and electrical parameters of a parallel I/O bus used to
connect initiators to devices. A processor-independent standard protocol for system-level
interfacing between a computer and intelligent devices including hard drives, disks, CD-ROMs,
printers, scanners, and other devices.
Single-Mode Fiber (SMF)—A single-mode fiber, typically 9 micron, although 8 and 10 micron
are also supported.
Synchronous Optical Network (SONET)—An ANSI standard for transmitting bits over fiber-
optic cable.
Target—For subsystems using the disaster-tolerant Data Replication Manager solution, the target
is the storage array that is the secondary or backup source of information. In the event of a system
outage, the database would be recovered from the target system.
T1—The standard North American carrier for transmission at 1.544 Mb/sec.
T3—The standard North American carrier for transmission at 44.736 Mb/sec.
Unspecified Bit Rate (UBR)—Offers no traffic-related service guarantees.
Virtual Channel (VC)—The lowest-order logical address in ATM. VC refers to a given circuit
on a link.
Virtual Channel Identifier (VCI)—The field of the cell header storing the VC address.
Virtual Path (VP)—The highest-order logical address in ATM. VP refers to a given group of
circuits on a link.
Virtual Path Identifier (VPI)—The field of the cell header storing the VP address.
VLD GBIC—Very Long Distance GBICs.
