SCSI Controller

The embedded Adaptec AIC-7899W dual function SCSI controller provides Ultra160 (LVDS), (Ultra 2), and Ultra wide (SE) SCSI interfaces as two independent PCI functions.

The Intel SHG2 baseboard provides active terminators, termination voltage, resetable fuse, and protection diode for both SCSI channels.

Modular RAID Capable PCI-X Slot 6

The SHG2 server board supports a modular RAID controller, such as the Intel® RAID Controller SRCMR, on PCI-X Slot 6. An add-in card installed in this slot leverages the onboard SCSI controller along with its own built-in intelligence to provide a complete RAID controller subsystem onboard. If a specified modular RAID card is installed, then SCSI interrupts are routed to the RAID card instead of the PCI-X interrupt controller effectively hiding the host-based I/O device from the system. The SHG2 Server Board uses an implementation commonly referred to as “RAIDIOS” to support this feature.

To use this feature, see “Enabling PCI-X on Slot 6 and Disabling On-board SCSI” on page 90.

IDE Controller

The system includes a dual-channel enhanced IDE 32-bit interface controller for intelligent disk drives with disk controller electronics onboard. The controller has two connectors, Primary and Secondary, located on the system board, each of which supports a master and a slave device.

The device supports:

PIO, ATA-100 Synchronous DMA, and bus master IDE transfer modes

Ultra DMA 33/66/100 synchronous DMA transfers

Master/slave IDE modes

Up to four devices

USB Interface

The SHG2 Server Board provides three external USB connectors on the rear I/O panel. The external connectors are defined by the USB Specification, Revision 1.1. One additional USB connector is supported internally through a 10-pin header on the server board that can be cabled to a front panel board. All four ports function identically and with the same bandwidth.

SHG2 specifications

Intel SHG2, short for Server High-Performance GPU 2, represents a significant evolution in graphics technology designed to meet the demanding requirements of data centers and high-performance computing applications. Developed to support a range of workloads, SHG2 is particularly optimized for artificial intelligence, machine learning, and data analytics.

One of the defining features of the Intel SHG2 is its impressive processing power. With numerous cores capable of parallel processing, it can execute multiple tasks simultaneously, leading to faster computation times. This architecture makes it incredibly efficient for applications that require heavy calculations and real-time data processing.

The SHG2 also embraces advanced fabrication technologies, moving to smaller nodes that enhance power efficiency while delivering higher performance. These innovations not only allow for improved thermal management but also contribute to the reduction of overall energy consumption, making the SHG2 a more environmentally friendly choice for server operations.

In terms of memory support, the SHG2 offers a robust configuration, accommodating high-bandwidth memory (HBM) that ensures quick access to critical data. This feature is essential for applications needing rapid data retrieval and integration, such as deep learning models where every millisecond counts.

Moreover, the SHG2 is built with compatibility in mind. It integrates seamlessly with existing Intel architectures, allowing organizations to leverage their current investments while upgrading their processing capabilities. This compatibility makes it easier for businesses to enhance their infrastructure without undergoing a complete overhaul of their systems.

Another salient characteristic of the Intel SHG2 is its support for virtualization. This allows multiple workloads to be handled simultaneously on a single GPU, maximizing resource utilization and enhancing overall system performance. As enterprises increasingly adopt cloud-based solutions, the ability to virtualize GPU resources becomes critical.

Security is also a major consideration in the design of the SHG2. Intel has incorporated various security features to ensure that data is protected against unauthorized access and vulnerabilities that could threaten system integrity.

As businesses increasingly turn to AI and machine learning to drive innovation, the Intel SHG2 positions itself as an essential tool for those looking to harness the power of advanced computing. With its impressive features, powerful performance, and forward-thinking design, is a strategic choice for organizations aiming to enhance their computational capabilities and meet the challenges of tomorrow's technological landscape.
