The Dell PowerEdge R820 is a four-socket, Xeon-based 2U server that not only outruns its predecessor, the PowerEdge R810, by a healthy margin but also provides substantially more expandability. The system tested by the CRN Test Center was outfitted with four Intel Xeon E5-4607 six-core processors running at 2.20GHz with 96 GB, a mere fraction of its maximum of 32 processor cores and 1.5 TB of DDR3 memory -- in 48 DIMM slots -- running at up to 1600MHz; the discontinued R810 maxed out at 1 TB.
Testers fired up the 64-bit version of Primate Labs' Geekbench 2.3.2. Dell's PowerEdge R820 delivered a top Geekbench score of 19,794, an increase of more than 30 percent from the PowerEdge R810 that we tested in March, 2010. Next we kicked off Intel's Iometer benchmark utility to measure the R820's transaction processing and throughput creds. Results were decent, with maximum number of 512-byte sequential reads at around 61,000 per second and a top transfer rate of 1.6 Mbps.
