Expand one PCIe slot to sixteen high-speed slots in 4U rackmount enclosure. When you want more I/O capacity and you need it to be fast, a super-fast x8 (40Gbps) or x16 (80Gpbs) PCIe connection to the host computer server helps eliminate workflow bottlenecks.
Seamlessly expand your server or workstation with PCI Express slots
Magma's ExpressBox 16 is the simplest solution to seamlessly increase the number of PCI Express® slots available to your server or workstation. ExpressBox 16 expands one host PCIe® slot to sixteen slots by extending PCI Express signals over a high-bandwidth x8 or x16 connection to an external Magma enclosure.
ExpressBox 16 consists of a pair of interface cards (x8 or x16), an iPass cable and a 4U rack-mount expansion chassis. The Magma expansion chassis is automatically configured by the System BIOS, with the expansion slots appearing transparently on the host computer.
