Introduction

1-3

Supports full backward compatibility for asynchronous, fast, Ultra 1, and
Ultra2 SCSI (80 MB/sec)

SCSI terminators and termination power sources must reside in the enclosure
subsystem

Note:

There is no support for high-voltage differential (HVD) SCSI

(RS-485 SCSI-3 compliant).

Motherboard Disk Cache (G-Series)

Adaptec AIC-2100 dual-port PCI disk cache ECC memory controller

PCI-to-PCI Bridge providing full CPU and PCI bus concurrency

Disk cache size modularity using standard SDRAM 168-pin ECC DIMM
(16 MB to 128 MB)

Battery backup switching regulator and control interface for disk cache memory

Battery Interface (G-Series)

Battery charger and battery control interface

Integrated software-controlled battery charger, diagnostics, and periodic battery
monitoring

Battery pack connection to the motherboard or to the backplane interface

Nickel Metal Hydride (NiMH) battery pack delivery of a minimum of 72 hours
continuous backup to disk cache memory

Hardware Configuration and Management Support
(G-Series)

Dual RS-232 serial ports

Analog-to-digital converter for power, temperature, and enclosure monitoring

Onboard standard PC-type lithium disk battery for continuous Real-Time Clock
(RTC) power when the unit is shut down

Dedicated channel activity LEDs, status LEDs, and alarm I/O to backplane
connector interface
