2 Key Technologies
2.1 Overview
The Intel
®
Xeon
®
E7-4800 and E7-8800 product family and the Intel Xeon processor 7500 series are
designed specifically for server applications. These processors feature 4-core, 6-core, 8-core, and
10-core processing to maximize performance and performance/watt for data center infrastructures
and highly dense deployments. These Intel Xeon processors also feature Intel Core™ micro-
architecture and Intel 64 architecture for flexibility in 64-bit and 32-bit applications and operating
systems.
The PowerEdge R910 implements a number of new technologies:
 Intel
®
Xeon
®
E7-8800 and E7-4800 product family
 32GB low-voltage (LV) DIMMs
 Fusion-io
®
solid-state storage cards
The Dell™ PowerEdge™ R910 also implements some existing key technologies:
 Intel 7500 chipset
 DDR3 RDIMM memory
 Internal dual SD module
 6G SAS technology
 10GbE Embedded NIC
