Dell Technologies offers a selection of rack servers for the Ready Stack compute infrastructure. The Ready Stack architecture can easily be scaled up by adding compute resources to existing nodes or adding nodes to the existing cluster, or by doing both. You can also easily scale out to a multipod and multirack architecture.
The latest generation of Intel Scalable processors, Cascade Lake, power this Ready Stack design. The processors provide up to 28 cores per CPU and clock speeds of up to 3.8 GHz in the PowerEdge rack servers, so you can reduce CPU socket-based licensing costs and achieve greater VM density.
The PowerEdge rack server platforms support the registered memory module (RDIMM) and Load Reduced DIMM (LRDIMM) memory types. LRDIMMs use an isolation memory buffer (iMB) to isolate electrical loading from the host memory controller. This buffer and isolation allow for the use of quad-ranked DIMMs to increase overall memory capacity. For general-purpose virtualization solutions, 2,666 MT/s RDIMMs are recommended. You can configure memory in various modes from within the BIOS. For optimized memory performance with most virtualization use cases, use the default mode, Performance Optimized. For improved reliability and resiliency, other modes, such as mirror mode and spare mode, are available.
The Mellanox CX4 LX 10/25 GbE dual-port adapter is the recommend adapter for virtual workload and host communication. The QLogic 2692 dual-port 16 Gb FC adapter is the recommended adapter for FC SAN storage connectivity.
PowerEdge servers support various BIOS configuration profiles that control the processor, memory, and other configuration options. Dell Technologies recommends that you:
