Multi-GPU Gen 3 PCIe Expansion Chassis - with Partitioned Four Host Backplane
ExpressBox 3600-P provides the optimum features for supporting world class High Performance Computing (HPC) applications that demand ‘mission critical’ features such as N+1 redundant power and cooling and high speed PCIe Gen 3 x16 connectivity.
ExpressBox 3600-P (‘-P’ for Partitioned) provides flexibility for High Performance Computing (HPC) applications by partitioning the PCIe expansion switching into four independent domains that can be connected to one, two, three, or four independent hosts. All PCIe resources share one common chassis for N+1 redundant power and cooling to minimize cost.
The EB3600 is optimized for server class applications and supports a variety of server class GPUs. Power and cooling are designed for up to 300W per GPU. Cooling is designed to support passive cooled GPUs. All critical components are hot swappable and designed for RAS applications. The EB3600 includes Magma’s Express I/O management for system control, monitoring and alarming.

What is the memory requirement for a certain host computer when using the EB3600 unit running GPUs?
It is recommended that systems be configured with a minimum of 8 GB of system memory, with a suggestion of 16 or 32 GB is appropriate for most of today’s applications and operating systems. GPUs require additional system memory to support memory copy operations, and the system memory should add to the base memory configuration, whatever BAR (Base Address Register) space memory that each GPU requires. An NVIDIA K40, for example, requires 16 GB of BAR1 space and if a base system is configured with 16 GB of system memory, the user should add 16 GB (32 GB total) of system memory PER K40 added through expansion. If the user is configuring 4 K40s, for instance, this would require 64GB additional system memory above and beyond what the base operation system and application requires. For 4 K40s and base system memory of 16GB, this would be 80Gb of total system memory to support the base application as well as the GPU memory requirement. NOTE: Always check the minimum system requirement of the GPU. This information is available from the vendors / manufacturers website.
What is the size of the PCI Express Host Card?
The host interface is standard half height/half length. Length: 7 inches (17.78 cm) Height: 2.25 inches (5.72 cm).
Does the host card contain an onboard switch?
No. The host interface card uses low latency retimers (no switch) for cable interfacing, resulting in a lower latency than competitive switch based solutions.
What is the cable interface?
Magma has designed a special Gen 3 cable with improved signaling characteristics over previous generation cables. This x8 or x16 cable interface allows true 0 bit error rate transmission for ultimate performance at Gen 3 signaling rates.
What length is the host cable?
1 meter and 2 meter cable lengths are available as ordering options.
How many boards are supported in the expansion chassis?
For the ExpressBox 3600-10, up to 10 peripherals are supported. For double wide (GPU) usage, up to 9 GPUs are supported). For the ExpressBox 3600-5, up to 5 peripherals or GPUs are supported.
What types of GPUs are supported?
Any PCI Express supported GPU may be used. The ExpressBox 3600 supported NVIDIA Tesla, GeForce and Quadro GPUs and full access to all GPUs is provided at the rear of the chassis. AMD FirePro and Intel Phi co-processors are supported.
What type of cooling is provided for peripheral boards?
The chassis provides N+ 1 redundant cooling fan. 4 fans are supplied, each with 175 cfm.
Are there any limitations to the types of boards that can be used in the ExpressBox 3600?
Although optimized for double wide GPU modules, any PCI Express board may be used within the system. The ExpressBox 3600 support Gen 3, Gen 2 and Gen 1 boards of any data width (x1/x4/x8/x16).
What size is the enclosure?
The enclosure is 16.8” (42.7 cm) wide x 22.125 (56.2cm) deep x 7” (17.8 cm) high (4U).
How are the power supplies configured?
Up to 4 1200/1500W hot swappable AC input PSUs may be configured. For 120V operation, each PSU is specified for 1200W; For 240V operation, each PSU is specificed for up to 1500W. At 120V, this provides a total of 4800W, or 3600W N+1 redundant. For 240V operation, total power is 6000W or 4500W N+1 redundant.
How many PCI Aux cables are provided for peripheral/GPU use?
Nine pairs of PCI AUX cables are supplied with the system, with each slot being supported by two 8-pin PCI AUX connectors. Total cable pairs: 18.
