Table 1. Specifications (7X69 and 7X70) (continued)
Processor (depending on
model)
Supports multi-core Intel Xeon processors, with integrated memory controller and Intel
Ultra Path Interconnect (UPI) architecture.
• Two processor sockets (expandable up to four) with minimal requirement of two
installed.
• Designed for LGA 3647 sockets
• Scalable up to 28 cores
• Supports Intel Extended Memory 32/64 Technology (EM32/64T)
Notes:
• When server installed with two processors, only 4U PCIe riser assembly 2 is
supported.
• When server installed with two processors and two AnyBay backplanes, 4U PCIe
riser assembly is not supported.
• When server installed with four processors and two AnyBay backplanes, only one 4U
PCIe riser assembly is supported.
