Figure 4: Each storage cartridge includes two SFF drives: either HDDs or SSD drives. Configuring the server trays You can optimize the server trays with a mix of compute or storage cartridges for the specific workloads you'll be running. For example, you can configure for maximum compute capabilities or for maximum storage. Table 1 shows some sample configurations. Table 1: Available servers and drives depending on configuration Configuration All-compute Number of compute cartridges per server tray 18 (72 SoCs) Number of storage cartridges per server tray 0* Mix of compute and storage Maximum storage solution *Network or MicroSD boot 6 (24 SoCs) 2 (8 SoCs) 12 (24 drives) 16 (32 drives ) SoC architecture The Calxeda EnergyCore SoC includes a quad-core processor and wraps other integrated components around it to make it an enterprise-ready system on a chip. It includes a management co-processor and a network fabric interface, as well as interface controllers for storage and networking. While the long-term vision of Project Moonshot is to share storage and network fabrics across the entire chassis, Redstone only partially incorporates those capabilities. It does share power and cooling through the chassis. The Calxeda EnergyCore SoC includes the following functionality (Figure 5): • EnergyCore quad-core processor subsystem • I/O controllers for Ethernet, PCIe, SATA, and SD storage cards • Integrated system management co-processor • Network fabric switch and network interfaces 6
