The 1500W, external XPRM-G3-ELRHE 4U 19" Gen3 Xpander Rackmount Elite from Cubix is a 4RU, PCIe expansion chassis. It can support one server/workstation connection with up to four 16-channel PCIe Gen3 high-performance dual slot cards plus two single slot 8-channel I/O cards per system. It provides a high-bandwidth external slot array for applications ranging from NVIDIA Quadro SVS to onset production applications, in media and entertainment. The Gen3 Xpander supports up to sixteen hard drives or DCI 2K projectors, or up to four 4K (or UltraHD) monitors and projectors via NVIDIA SVS and G-Sync III. This system includes a 4-channel slot (power only) for use with the NVIDIA G-Sync III card in high-end visualization applications.You can install four dual slot GPUs (Graphical Processing Units) for hardware acceleration purposes as well as other types of third party I/O controllersFour PCIe Gen 3 x16 expansion slots (supporting both dual slot and single slot cards) and two 8-channel slots (supports single slot cards) per MIB (Main Interface Board), total of six slots per systemOne MIBs per 4RU, 19" rack mount system (one PCIe backplane, one 16-channel data cable, and one 16-channel HIC)An independent 1500W power supply and cooling fan to meet expansion requirementsSimple, quick installation with minimal impact per rackmount computer. Install a HIC (Host Interface Card) and drivers for installation of devices in GPU-XpanderEach x16 cable and connector provides a 250 mating duty cycle (purchase additional x16 HICs for sharing with multiple host computers)Hardware-acceleration using NVIDIA graphics and GPU cards for application accelerationEnhances server I/O infrastructure capabilities without adding serversBenefitsAdds four dual slot GPUs for supporting rackmount computers, which have limited slot expansion capabilities and limited power supply capacitiesSupports one host PC or Apple Mac Pro workstation with one Xpander Rackmount EliteApplicationsDaVinci Resolve Win/Linux, Autodesk 3ds Max, Flame, Smoke, Chaos Group V-Ray, Assimilate Scratch, rendering, Fusion-io SSDs, NVIDIA Quadro SVS, on-set apps
