Architecture (EISA) bus slots for add-in boards. EISA is fully
backward-compatible with Industry Standard Architecture (ISA). You can install
old or new ISA and EISA add-in boards in your server, which may save your older
hardware investments. Figure 10 shows you a block diagram of the Netfinity 7000
system architecture.

2.5.1 Performance Recommendations
We recommend that you install an I/O-intensive adapter, such as RAID, and a
network adapter in the second PCI Bus (PCI Bus #1), as the first PCI bus
connects to a PCI to EISA bridge.
The PCI to EISA bridge controls the diskettes controller, serial and parallel
interfaces, the Video Graphics Array (VGA) port and the Integrated Drive
Electronics (IDE) port so you can achieve a little better performance if you install
such an adapter in the second PCI bus.
