Cost Effective Solution for Expanding I/O Capacity Magma Expressbox7 is a PCI Express to PCI Express Expansion chassis system that provides a simple, cost-effective solution for expanding the available PCI Express slots of workstations and servers. This allows for significant cost savings to organizations since it eliminates the need to invest in new computer hardware in order to be able to accommodate the growing need for I/O expandability. Expressbox7 expansion solution provides 7 full-length PCI Express slots. This is a stand alone chassis in an industry standard enclosure with its own power supply. The PCI Express slots are equipped to be hot swappable. This chassis allows the flexibility to seamlessly expand I/O capabilities of servers and workstations utilizing the built-in transparency of PCI Express architecture. Expressbox7 is the box of choice when augmenting Blade Server capabilities by adding Blade compute engines built around Expressbox7. Expressbox7 satisfies the ever increasing requirements of PCI Express I/O fabric in servers that capitalize on inherent PCI Express architecture for I/O virtualizations and workstations that implement VMware. Expressbox7 provides the basis for carrier grade communication equipment built around the Advanced Telecommunications Computing Architecture (ATCA). ExpressBox7 can accommodate up to 7 PCI Express cards with a MacPro providing users with the capability to achieve full track counts in this configuration. * Digidesign qualification pending Expressbox7 consists of a PCI Express Host Card, a cable and a chassis. Magma's Expressbox7 is automatically configured by the System BIOS making all of the slots transparent to the host computer. Benefits Industrial solution for adding up to 7 PCI Express cards to one computer Allows for attachment to full-length PCI Express cards to computers with limited card space Power to individual PCI Express slots can be selectively turned off without powering down entire system Low profile host card allows for easy installation in low profile computers Supports peer to peer transfers between cards in slots Optional redundant power supplies share load during normal operation and in the event of a failure of one the other assumes full load sounding an audible alarm
