The Magma PCI Express-to-PCI Expansion System provides a simple, cost-effective solution for expanding the capability of your PCI Express based computer. As computer manufacturers migrate to PCI Express, the number of available PCI slots has been reduced or completely eliminated. However, many companies have invested a substantial amount of capital on solutions built around conventional PCI and PCI-X hardware. The Magma PCIe to PCI-X expansion system provides a "migration path" to PCI Express while protecting your PCI hardware investment.


Where PCI meets PCI Express
The Magma PCI Express-to-PCI Expansion System is designed to match the through-put required by the majority of PCI cards on the market today. The expansion chassis contains six PCI-X slots which are connected to the host computer through a 8 lane (x8) PCI Express host interface card and a high-performance cable.


Cost-Effective Migration and Increased I/O Capacity
The Magma PCI Expansion solution provides a cost-effective migration path to new PCI Express-based computers while maintaining a consistent PCI configuration. In addition, Magma products significantly increase Input/Output (I/O) capacity and scalability. Multiple expansion systems can be combined to provide an almost unlimited number of PCI slots* to a single computer. This type of scalability is especially useful in industries such as Telecom, Data Acquisition, Video Monitoring, Server Storage and Manufacturing Test Fixtures.
*As defined by the PCI Local Bus Specification, the theoretical maximum per computer is 255 PCI buses.


Easy Installation
The Magma 6 Slot PCI Express-to-PCI Expansion System (PE6R4-I) consists of a x8 PCI Express host card, a high-speed iPass cable and a PCI(x) expansion chassis. The host card relays signals from the PCI Express slot inside the computer motherboard to a PCI(x) backplane inside the expansion chassis. The system is automatically configured by the system BIOS and all six high-performance PCI(x) slots within the expansion chassis appear transparent to the host computer.


*Please note that PCI and PCI-X are backwards compatible.

"I am astonished at how easy it was to get it up and running. I am ecstatic about getting my system running again and saving over $10,000 with the help of your product. I have never installed or removed PCI or PCI-E cards from a computer. I simply followed the instructions that came with the Magma expansion chassis, along with some additional visual help from YouTube. Magma is the way to go!! Today started out as a very stressful day. It will end with a great night's sleep due to the fact that your product did exactly what your company claimed it would."


- Aaron King, Audio & Music Production


"Magma saved our school over $35,000 by giving us the flexibility to use current Pro Tools software with PCIx HD Core and Accel cards. Our instructors can train students with the newest Pro Tools software while still using older hardware. The Magma chassis allows us to utilize our initial investment in Pro Tools HD hardware as long as we possibly can while we plan to upgrade the Digi hardware at some point in the future."
- Mark Kirchner, Chief Academic Officer, Studio West
