System Overview

PDSI's ComputeNode4U (Node4U) is an efficient carrier-grade CompactPCI® solution developed for the embedded control and communications marketplace. This 8-slot cPCI chassis measures only 7" high, and may be densely packed into any new design or existing rack. The cPCI form factor offers horizontal scalability with front and rear accessible I/O for easy service and maintenance.

Configurable with various processors—SunTM, Intel®, PowerPC and custom-designed—Node4U provides high performance in a compact unit. Using the H.110 backplane with one system slot and seven I/O slots provides superior slot density and a standard 3.5” SCSI hard drive located above the power supplies offers reliable data storage. For applications requiring greater density, higher capacity, hot-swappability or disk mirroring, PDSI offers various “in-box” solutions.

PDSI's Node4U is designed with a system alarm card for monitoring and control status. The system alarm card communicates with the system CPU through an I2C Bus Interface or an RS-232 interface. The alarm card is designed to be hot-swappable as a Field Replaceable Unit (FRU) and does not require a cPCI card slot.

Specifications

With its horizontal design and superior air cooling functionality, Node4U is a cost-effective product providing the highest levels of quality and manageability in mission-critical applications.

With front accessible power supplies in a load-sharing 2+1 redundant configuration, these hot-swappable power supplies are standard with dual DC feed or single AC feed. As with all PDSI products, Node4U combines expert Rapid Product Realization design, branding and testing services for a complete SKU utilizing customer-specified third party components for Commercial off-the-shelf products, greatly reducing time to market.
