IBM 600 Product Overview page 10

Model Comparison
The Model 600 and Model 800 are
functionally comparable but have the
differences that are summarized in the
following table:
Model Feature
Slots
600 6
800 8
Note that the ordering/pricing structure
requires a separate explicit order for the
Model 800 processor card, while the
processor card is included in the base
price for the Model 600.
To help ensure continuous operation a
single, redundant power supply can be
optionally ordered for the 8270 Model
800. Only one power supply is required
to support a fully populated 8270; the
second power supply on the Model 800
is redundant. Both power supplies are
load-sharing and hot-pluggable. The
Model 800 chassis also includes two
fans, one of which is redundant.
Positioning
Except for considerations pertaining to
number of feature slots and redun-
dancy (power) characteristics, the IBM
8270 Model 600 is suitable for use in
the same environments as the current
8270 Model 800. However, with different
redundancy characteristics and
feature slots, the Model 800 can be
used in the network backbone or near
the center of the network, while the
Model 600 can be better placed closer
to the edge rather than the center of
your network.

The 8270 should be positioned against
the IBM 8272 or 8272 modules for the
8260/8265 as follows:
A key parameter affecting LAN Switch
product positioning is processor
loading, especially with heavy broad-
cast traffic or bridged explorer traffic.
The 8270 Models 600 and 800 with
their high-performance CPU, redun-
dant power option (Model 800 only),
flexibility and scalability offer a
powerful solution for all Token-Ring
switch applications and environments.
Applications can range from small
office networks to large establishment
backbones. The 8270 is the correct
choice for carrying traffic among large
dynamic network populations.
Conversely, the IBM 8272-based
products which use a more modest
processor, should be viewed primarily
as workgroup switches at the edge of
the network. Certainly, existing IBM
8260 customers who want to integrate
LAN switching into their single platform
may prefer to use one of the 8272 LAN
Switch Modules for the IBM 8260, taking
these guidelines into consideration.
