Katmai New Instructions
. .
. .
KNI refers to the addition of 70 new instructions to the MMX instruction set. The new instructions
. .
primarily refer to the new SIMD-FP registers, but some new integer instructions also have been
. .
. .
added. The new instructions are particularly useful for multimedia applications such as 3D
. .
rendering and video encoding and decoding.

Tolerance of server downtime continues to decrease, as companies become more global,
. .
. .
decentralized, and aware of downtime costs. The ProLiant 8000 server answers the demand for
. .
high availability by incorporating the following features into the server hardware:
. .
. .
. .

PCI Hot Plug technology

. .
. .
Redundant array controller technology
. .
. .
Redundant network interface controller (NIC) technology
. .
. .
. . Redundant, hot-plug fans
. .
. .
Redundant PPMs
. .
. .
Redundant, hot-plug power supplies
. .
. .
Hot-plug drives
. .
. .
. .
Redundant components help ensure that the server is highly fault tolerant. In redundant
. .
configurations, if a power supply, fan, or PPM fails, the redundant standby component can take
. .
. .
over operation with no downtime to the server. With the addition of hot-plug capabilities, server
. .
downtime can be eliminated while components are being replaced, added, or upgraded.
. .
. .
. .
PCI Hot Plug Technology
. .
. .
. .
The Compaq ProLiant 8000 server incorporates industry-standard PCI Hot Plug technology. This
. .
technology, pioneered by Compaq, adds hot-plug capabilities to existing PCI adapters for increased
. .
. .
system availability and serviceability. Compaq led the industry by licensing its PCI Hot Plug
. .
implementation to Intel, thus broadening customer access to this industry-standard technology.
. .
. .
. . Compaq's implementation of PCI Hot Plug incorporates electronics into the server to control each
. .
PCI Hot Plug slot individually, so that a single slot can be powered down without affecting the
. .
. .
operation of the other slots. Compaq's implementation of the PCI Hot Plug standard allows the
. .
following capabilities while the system is running:
. .
. .
Hot replacement – replacing a single PCI adapter with a similar adapter
. .
. .
. .
Hot upgrade – replacing a PCI adapter with an upgraded adapter
. .
. .
Hot expansion – adding a PCI adapter to an empty slot
. .
. .
The ProLiant 8000 server supports all three hot-plug capabilities for all 64-bit and 32-bit PCI Hot
. .
. .
Plug slots. These capabilities can be added incrementally, depending on the OS implementation.
