The Xpander Rackmount Series II Gen3 HPC Expansion Chassis from Cubix is an external PCIe expansion chassis that can support one server connection and up to four single-slot or two dual-slot GPUs per system, which enables massive parallel calculations separate from the server, enhancing system performance and flexibility. It also provides a 700W independent power supply and variable speed, temperature-controlled cooling fans. This feature of the chassis can meet any expansion requirement in environments ranging from IT Data centers to the noise-sensitive digital production sets or post-production workstation offices.
