Supermicro TwinPro® 2U 4-Node SuperServer

The Chassis and Architecture This is a high-density, multi-node compute server. Instead of a single motherboard inside the 2U chassis (which is 3.5 inches tall), this system houses four separate, independent computer nodes that slide into the back of the chassis. Chassis Model: Supermicro CSE-217HQ+-R2K02BP (or a highly similar variant in the 217 series). The OEM Badge: The SGI label on the power supply and chassis (Model No: CMN2112-217-20) indicates this was part of SGI’s Rackable C2112 series. SGI would buy barebones supermicro systems, rebrand them, install their own specific firmware, and sell them as high-performance compute clusters for enterprise and scientific computing. Storage Plane: The front of the server features a backplane with 24 x 2.5” drive bays (6 drive bays allocated to each of the 4 nodes). Power: It utilizes two massive, redundant titanium-level power supplies (likely 2000W each) that feed power to a central backplane, which then distributes it to the four individual nodes. The Motherboard / Node Specifications: The image of the motherboard PCB clearly shows the model: SUPER X10DRT-PIBF (REV: 1.10). You have four of these boards, one for each node. This is an enterprise-grade, proprietary form factor motherboard designed specifically for the Supermicro Twin architecture. Processor & Memory (Per Node). CPU Sockets: Dual LGA 2011 (Socket R3). Supported CPUs: Intel Xeon E5-2600 v3 and E5-2600 v4 families (Haswell-EP and Broadwell-EP architectures). It supports CPUs with up to 22 cores each (44 cores per node, 176 cores total for the chassis). The maximum supported Thermal Design Power (TDP) is 145W per CPU. Memory: 16 DIMM slots (8 per CPU). It supports up to 2TB of DDR4-2400MHz ECC 3DS LRDIMM memory per node (8TB total for the chassis). Storage & Expansion (Per Node). Chipset: Intel C612. Onboard SATA: The chipset supports 10 SATA3 (6Gbps) ports natively. Expansion Slots: It features a proprietary riser card interface that supports a combination of PCIe 3.0 x16 and x8 slots. Based on standard supermicro builds using this board (like the SYS-2028TP-HC1FR), it likely utilizes a SAS3 hardware RAID controller (like a Broadcom 3108) mounted on a mezzanine card to handle the front SAS drives. Networking & Management (Per Node). The “IBF” Designation: The -PIBF suffix on the motherboard model is critical. It stands for InfiniBand FDR. This board has an integrated Mellanox ConnectX-3 single-port InfiniBand adapter capable of 56Gbps throughput via a rear QSFP connector. This is specifically designed for ultra-low latency compute clustering (which is exactly what SGI built). Ethernet: Dual-port Gigabit Ethernet via an Intel i350-AM2 controller. IPMI: Integrated IPMI 2.0 with KVM over LAN, powered by an ASPEED AST2400 BMC (Baseboard Management Controller), accessed via a dedicated RJ45 management port.
