One Stop Systems EB16-SX8-X16 Specifications



    ExpressBox 16 Smart 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. When combined with Magma's software utility, Express I/O Manager, technology managers have the flexibility to partition slots inside the expansion chassis to up to four separate servers. Express I/O Manager also provides access to monitor the most critical components like power temperature, fans and PCI Express links through an Ethernet connection. The software tool can be integrated with any SNMP agent in the IT network.

    Smart, Manageable, Multi-Host Expansion

    PCI Express connectivity has matured well beyond the early days of PCI into a fully capable "outside the box" high-speed interconnect for the most demanding mission critical applications in HPC and IT infrastructures. As cloud computing and remote services become standard, offering a flexible, manageable, and cost effective expansion solution is demanded for high-speed Ethernet, HBAs, Fibre Channel SAN controllers, GPUs, video accelerators, and more.

    Expansion Partitioning Between Multiple Servers

    A unique feature of the ExpressBox 16 Smart allows the PCIe expansion slots to be partitioned between 4 different servers. Using the Express I/O Manager, 3 different partitioning configurations can be selected. In the default configuration, all 16 expansion slots are accessed by one host computer. Configurations 2 and 3 provide up to 3 expansion cards per server at x16 speeds, and up to seven expansion cards for a fourth server at x8 speeds. A separate host adapter is required for each server. ExpressBox 16 Smart 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.
