Board Types

The CPU/Memory+ board supports up to two UltraSPARC II CPU modules and
16 DIMM slots.
The SBus+ I/O board includes two SYSIO ASICs that provide two SBuses: one for
two plug-in SBus cards and two GBIC (100 MB/sec Fibre Channel) interfaces, and
one for one plug-in SBus card and the onboard devices (10/100 Mbit TPE and
Single-ended Fast/Wide SCSI).
The Graphics+ I/O board includes one SYSIO ASIC that provides a single SBus
for two plug-in SBus cards, two GBIC (100 MB/sec Fibre Channel) interfaces, and
the onboard devices (10/100 Mbit TPE and Single-ended Fast/Wide SCSI).
The PCI+ I/O board has two PCI bus connectors, each of which can accommodate
a PCI riser card. Each riser card accommodates one PCI short card. In addition,
onboard devices provide Fast Ethernet (10/100 Mbit) and Fast Wide SCSI
interfacing.
The Enterprise 3500 server features a high-speed centerplane bus that includes
separate address and data buses.
