Compaq Servers Designed for the Future

To take advantage of this next-generation technology and to allow a growth path for the future,

Compaq engineers specifically designed the subsystems of the ProLiant 3000 with the flexibility

to accommodate future needs for the Deschutes/Slot-1 processor and the ProLiant 7000 for the

Deschutes/Slot-2 processor and for up to 8-way Deschutes/Slot-2 configurations.

By planning in

advance for Deschutes/Slot-2 and 8-way requirements, Compaq has been able to engineer the

ProLiant 7000 power supplies, thermal capacity, and chassis with extra headroom to

accommodate this additional load.

Customers should expect the following from Compaq systems and Deschutes processors:

•

In-chassis upgrades for the ProLiants 6000, 6500, and 7000

•

Performance benefits:

4-way Deschutes/Slot-2 400MHz will outperform the 8-way Pentium

Pro for a smaller cost and with far greater processor longevity

•

System bus speed up to 100MHz

•

Processing core operating frequency

- up to 450MHz on 100MHz system bus

•

L2 cache sizes of 512KB, 1MB and 2MB

Other Companies' Choices

Currently, ALR, NCR, Axil, and Unisys (and others that OEM their products) all offer Pentium

Pro-based 8-way servers, according to a Meta Group report.

With 4-way Deschutes/Slot-2

systems offering equivalent performance to (if not greater than) 8-way Pentium Pro systems, user

investment in >4-way Pentium Pro systems becomes tactical.

These investments will be further

marginalized; because of major differences in Pentium Pro and Deschutes/Slot-2, upgrading

Pentium Pro-based servers will require at least entire system board replacements, if not an entirely

new box.

Further, given Intel's Corollary acquisition, Meta Group believes the majority of

existing >4-way vendors will cancel proprietary 8-way Deschutes/Slot-2 plans. In other words,

vendors who are not using the Intel 8-way architectures will run the risk of not adhering to widely

adopted standards.

There are several other common potential weaknesses to these competitive architectures including

transitions requiring significant engineering, memory controller problems, incompatibility with

the Intel 450NX chipset, and no support for delayed transactions with the Intel 450NX host-to-
