that allows fast, easy addition and replacement of drives, also called “Hot-swap
subsystem” (see Chapter 3, “Hot-Swap Subsystem” on page 41 for information
about this subsystem).
This system allows up to a maximum of 40 GB of internal storage capacity and
features a flexible I/O subsystem of three PCI, three ISA and four shared slots.
The most important RS/6000 Model F30 RAS attributes are the following:
ECC memory
Integrated service processor
Hot-swap disk drives
Concurrent diagnostics
Due to all these features, the Model F30 is the ideal server for applications that
require large memory (up to 512 MB) combined with large disk capacity.
2.5.1 Standard Features
In this section, we describe the standard features of the RS/6000 Model F30s and
point out their most important characteristics.
Processor Subsystem
The PCI-based RS/6000 Model F30 server features the PowerPC 604
microprocessor at 133 MHz. The processor includes an L1 cache composed of a
16 KB instruction and a 16 KB data cache.
The L2 cache is integrated onto the CPU board and is always present in the base
system. The L2 cache is 512 KB in size.
Memory
The Model F30 comes standard with a 32 MB ECC memory DIMM in one memory
slot. The system memory can be expanded up to 512 MB. For this reason, eight
memory sockets are provided which accept 16 MB, 32 MB or 64 MB 168-pin
DIMMs. As DIMM sockets are used, a single memory slot can be added each time
with no need to add them in pairs.
No Select Feature for Memory
The standard 32 MB memory DIMM cannot be selected for memory upgrades in
the initial order.
Either parity or ECC memory DIMMs can be used and mixed together, providing
great flexibility. This allows the customer to easily upgrade the processor cards
without worrying about which kind of memory is installed.
Bays
The system contains ten standard bays and twelve optional hot-swap disk drive
bays, as shown in Figure 10 on page 33.
