The Supermicro MicroCloud modular server system provides the high density, performance, efficiency and cost savings required for today's demanding server deployments. The 12/8 modular server nodes are conveniently integrated into a compact 3U chassis that is only 29.5/23.2 inches deep, saving over 72% of rack space when compared to traditional 1U servers optimized for the best performance per rack. The cable-less, hot-pluggable server nodes operate independently. Each node provides up to 128GB of DDR3-1600/1333MHz of ECC LR/RDIMM memory, one PCI-E 3.0 x8 expansion slot for low-profile add-on card, and two 3.5 or four 2.5 SATA 3.0 (6Gbps) hard disk drives. The MicroCloud system utilizes redundant Platinum Level (94%) high-efficiency power supplies and sophisticated cooling zone controls for a Green energy profile. Each node is powered by processors from either the newest Intel® Xeon® E3-1200v2 & E3-1200 v3 families (5037MC and 5038ML models) or E5-2600 family up to 130W TDP; or the 8/4-Core AMD Opteron™ 3000 series
