Onboard SCSI (2021M-82R+ only)
An onboard Adaptec AIC-7902W dual-channel SCSI controller in integrated into the
H8DM8-2, which supports eight 80-pin SCA Ultra320 SCSI hard drives. The SCSI
drives are connected to an SCA backplane that provides power, bus termination
and confi guration settings. The SCSI drives are hot-swappable units.
Note: The operating system you use must have RAID support to enable the hot-
swap capability and RAID function of the SCSI drives.
PCI Expansion Slots
The H8DME-2/H8DM8-2 has six PCI expansion slots, which includes two PCI-Ex-
press x8 slots, two 64-bit 133 MHz PCI-X slots and two 64-bit 100 MHz PCI-X slots.
(On the H8DM8-2, one 100 MHz PCI-X slot supports Zero Channel RAID.)
Onboard Controllers/Ports
One fl oppy drive controller and one onboard ATA/133 controllers are provided to
support up to two IDE hard drives or ATAPI devices. The color-coded I/O ports
include one COM port (an additional COM header is located on the serverboard),
a VGA (monitor) port, two USB 2.0 ports, PS/2 mouse and keyboard ports and two
gigabit Ethernet ports.
ATI Graphics Controller
The H8DME-2/H8DM8-2 features an integrated ATI video controller based on the
ES1000 graphics chip. The ES1000 was designed specifi cally for servers, featuring
low power consumption, high reliability and superior longevity.
Other Features
Other onboard features that promote system health include onboard voltage moni-
tors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU
overheat sensors, virus protection and BIOS rescue.
