SunFire3800,4800,4810,and6800Platforms
There are four models of Sun Fire platforms as shown below. They are
Midframe servers built around UltraSPARC™-III processors and PCI or
hot-swappable cPCI I/O.
They have been developed under the codename of serengeti. They have
gone through a number of name changes since their inception; they are
included below for your reference:
●K6 > Serengeti SP > Serengeti-8 > Sun Fire 3800
●K12 > Serengeti MD > Serengeti-12 > Sun Fire 4800
●R12 > Serengeti ME > Serengeti-12i > Sun Fire 4810
●R24 > Serengeti DS > Serengeti-24 > Sun Fire 6800
●All the Sun Fire 3800 - 6800 range require Solaris 8 Update 4, S8U4
(Solaris 8 4/01) as a minimum.
●Memory figures on pages 11 - 14 assume 1GB DIMMs, which are
only supported on 900MHz and faster system boards.

Sun Fire 6800
The Sun Fire 6800 is a highly available, large-scale system.
The Sun Fire 6800 has the following features:
●Support for 2 to 24 UltraSPARC™-III/III Cu processors, mounted on
six system boards.
●Up to 192 Gbytes of ECC memory.
●Thirty-two PCI I/O slots or 16 hot-swappable cPCI slots or
combinations of PCI and cPCI, mounted on four I/O boards.
●Support for up to four domains. Three or four domains require two
segments. One or two domains require one segment, although there
are advantages with creating two domains in two segments.
●The Sun Fire 6800 has two Power Grids.
●Each Power Grid can have N+1 AC power redundancy, assuming
the customer has two separate supplies into his facility. (See page 45)
●There is N+1 DC power redundancy in each Power Grid.
●Four Fan Trays providing N+1 cooling redundancy.

The Sun Fire platforms are organized into multiple administrative/service
layers.
Each layer provides a set of tools that allow you to configure, monitor,
service, and administer various aspects of the platform.

SystemBoardASICs
The system board CPUs and memory are configured in pairs, (two pairs
per system board maximum) interconnected with a dual cheetah data
switch (DCDS). The DCDS provides a data path between the CPUs and
the L1 Sun Fireplane switch.
The system board L1 (level 1) Sun Fireplane switching logic consists of an
address repeater (AR) and 4 x data switch (DX) ASICs.
Each system board contains a system data controller (SDC). The SDC has
two functions; it multiplexes the console bus connections to allow all
system boards and Sun Fireplane switch boards to communicate to each
of the system controllers.
It is also the brains of the operation behind the data crossbar. If a data
packet is considered as a train, the DXs are like the tracks and the SDC is
like the signal box; the SDC routes the data.

SystemBoards,Physical
The Sun Fire system board houses either two or four UltraSPARC™-III Cu
900 MHz, 1050 MHz or 1200 MHz processors, or UltraSPARC™-III
750MHz processors.
Each processor supports two physical banks of memory.
Each memory bank consists of four dual inline memory modules
(DIMMs) which gives, 8 x DIMMS per CPU (See page 18)
Memory capacity can also be mixed but not within the same bank.
The processor’s L2-SRAM (also known as Ecache) consists of two cache
modules mounted on their own pcb’s, each module being 4MB in size,
giving 8MB per CPU.
Neither the CPU modules or the L2-SRAMs are field replacable.
Mixing CPU speeds of 900MHz, 1050MHz and 1200MHz within a
domain or platform is supported.
750MHz CPUs cannot be included in mixed-speed configurations.

CPU&MemoryConfiguration
Each CPU processor has two corresponding physical DIMM banks.
Each physical bank is split into two logical banks
It is possible that a processor might not have any DIMMs installed in
its corresponding DIMM bank, but a populated DIMM bank must have
a corresponding CPU processor installed in order for that memory to
be utilised.
The system board supports the following DIMM sizes:
●256MB DIMM Part number 501-5401
●512MB DIMM Part number 501-5030
●1GB DIMMs, part numbers 501-6109 & 540-5086 are only supported
on 900MHz and faster system boards.
