Dell EMC Ready Stack offers customers a selection of rack servers for their 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 multi-pod/multi-rack architecture.
The latest generation of Intel Scalable processors, Cascade Lake, power this Ready Stack design. With up to 28 cores per CPU and clock speeds of up to 4.0 GHz in the PowerEdge rack servers, you can reduce CPU socket-based licensing costs and achieve greater VM density.
The PowerEdge rack server platforms support the 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 performance-optimized virtualization solutions, 2,933 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 Gb dual-port Ethernet adapter is the recommend adapter for virtual workload and host communication. The Emulex 35002 dual-port 32 Gb FC low-profile 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:
