RAID (HOT-559S)
At today, the more network storage capacity expands, the more critical it becomes to
find a solution that maximizes data availability and performance. While tape backup
meets disaster recovery requirements, it does not ensure that continuous availability
and data integrity necessary to keep your network up and running. The
Redundant
Array of Inexpensive Disks (RAID) support on-line, real-tim data recovery that
overcomes the physical limitations of hard disk drives to delevery uninterrupted data
access.
RAID storage systems offer the potential for exceptional data availability and
performance that is far superior to individual drives.
HOT-559S provides an optional RAID slot for Adaptec PCI RAID adapter to fulfill
RAID solutions.
1.6 I/O Controller
Control for the integrated serial ports, parallel port, floppy drive, is incorporated into
a single component, the ITE 8680F. This component provides :
Two 16C550-compatible UARTs with send/receive 16 byte FIFO
Support for an Infra Red interface
Multimode bidirectional parallel port
-- Standard mode; IBM and Centronics compatible
-- Enhanced Parallel Port (EPP) with BIOS/Driver support
-- High Speed mode; Extended Capabilities Port (ECP) compatible
Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy
support)
1.7 Real-Time Clock, CMOS RAM
The onboard real-time clock (RTC) is builted in ITE 8680 I/O chip which provide a
24-hour clock mode and totally nonvolatile with over 10 years of operation in the
absence of power. The RTC can be set via the BIOS SETUP program. The RTC also
supports 128byte battery-backed CMOS RAM in two banks which is reserved for
BIOS use. The CMOS RAM can be set to specific values or cleared to the system
default values using the BIOS SETUP program. Also, The CMOS RAM values can be
cleared to the system defaults by using a configuration jumper on the HOT-559(S)
main board.
