Memory speeds are increased to 1,866MHz and Dell has implemented its patented Fault Resilient Memory (FRM) feature. Supporting the new Reliable Memory Technology feature of VMware's vSphere 5.5, this allows a protected memory zone to be created for the hypervisor without taking up half the system memory.
The Dell Processor Acceleration Technology (DPAT) targets high frequency trading applications that require consistent and predictable processor performance. Intel's Turbo Boost transitions can increase latency and jitter but DPAT allows you to fix the number of active cores and Turbo Boost speed to minimise these effects and provide a smoother performance.
