IBM Eserver xSeries 366 Technical Introduction 3
Current models
Table 1 shows the x366 models that were announced in March 2005.
Table 1 x366 models announced in March 2005
The x366 supports one, two, three, or four processors.
Both models support a maximum of 64 GB using 4 GB DIMMs in 16 sockets. To achieve the
maximum, you will need to install three additional memory cards (one four-socket card is
standard), remove the standard pair of 1 GB DIMMs and insert 16 DIMMs.
The x366 has six internal PCI-X 2.0 slots. Unlike the x365, the x366 does not support the
attachment of an RXE-100 Remote Expansion Enclosure. The RSA II SlimLine and
ServeRAID-8i options do not use any of these six PCI-X slots.
IBM XA-64e third-generation chipset
The x366 uses the third generation of the IBM XA-64e chipset. The architecture consists of
the following components:
One to four Xeon MP processors
One Hurricane Memory and I/O Controller (MIOC)
Two Calgary PCI Bridges
Figure 3 on page 4 shows the block diagram of the x366.
Dual-core capability: In addition to the single-core Xeon processors MP available today,
strategic intent of IBM is to support dual-core microprocessor technology on the x366
server at such a time that this technology becomes generally available from our partners.
The strategic intent also includes releasing a dual-core upgrade option kit to enable
customers to upgrade from single-core to dual-core technology in the future. In both cases,
this support may require updated server components made available in future revisions of
the x366.

Note: x366 Express models are also available in some geographies. These systems have
additional processors, memory, disk, or a second power supply standard. Consult your
sales representative for more information.
