The HT-2000 is targeted at the volume server market with the capability to
efficiently span from one-to-eight CPUs without incurring large latencies.
The HT-2000 is a highly-scalable SystemI/O solution for 64-bit/32-bit processors
that can be configured to meet OEM needs for a variety of product segments. The
dual processor configuration shown above can be used for mainstream tower and
rack servers. Additional HT-2000 devices can be added to a system to scale to
larger multi CPU servers.
The HT-2000 is a high-performance HyperTransport to the PCI/PCI-X bridge and
PCIe bridge, capable of tunneling the data between the two HyperTransport ports.
The HyperTransport tunneling enables an efficient four-way system as shown
above (on the right), where a base configuration can be created with fewer
devices.
The HT-2000 takes I/O bandwidth, configurability, and scalability to
unprecedented levels. The 16x HyperTransport port can operate at a frequency of
1-GHz double-data rate in both the transmit and receive directions to aggregate up
to a total bandwidth of 8 GBps. This bandwidth is available to communicate with
devices such as the processor or a host bridge.
The 8x HyperTransport port can operate at a frequency of 800-MHz double data
rate in both the transmit and receive directions to aggregate up to a total
bandwidth of 3.2 GBps. This bandwidth is available to communicate with
HyperTransport I/O hubs such as the HT-1000.
The HT-2000 offers the best I/O configurability available. The PCI-X bus
supports up to five bus masters and deep transaction queues, and enables
designers to implement the right balance between performance and slot count as
required by their systems. The PCI-X bus is capable of supporting all modes up
to 133 MHz.

For the next-generation low-latency, high-bandwidth I/O interconnect PCIe, the
HT-2000 offers an array of choices to match the bandwidth needs of the device as
well as the number of devices that need to be supported on the platform. The 17
serial links operating at 2.5 GHz can be configurable to four PCIe masters. Some
sample configurations that are possible are x8 + x8 + x1, x8 + x4 + x4 + x1, or
x4 + x4 + x4 +x4, or x8 + x4 + x1. Combinations of link widths that are lower than
the ones mentioned are possible. No other device in the marketplace matches this
level of flexibility for PCIe.
The HT-2000 takes integration a level further by offering two server class GbE
NIC ports. The high-performance MAC + PHY + SerDes combination within the
device provides the two Ethernet ports that every server needs in the most
cost-effective way. No feature compromises have been made with respect to the
embedded Ethernet controllers, and they offer such server class features as link
aggregation, VLAN tag support, jumbo frame support, packet filtering, and
classification. The UMP interfaces to a Baseboard Management Controller
(BMC) and allows the BMC to send and receive system management information
through the GbE port. This dedicated management interface allows for a much
higher bandwidth as compared to the traditional SMBus, making video
redirection possible, and eliminates the need for an Ethernet port on the BMC,
which saves cost.
Multiple HT-2000 devices can be used to scale out the system in terms of
processors and I/O connectivity for building higher-end multiprocessor systems.
The high levels of integration, enterprise server features, I/O flexibility, and
device scalability make the HT-2000 the best-in-class SystemI/O solution in the
market for building the servers.
