Additional information

Components Specification
Machine types 7X18 – 1 year warranty
7X19 – 3 year warranty
Form factor 2U rack.
Processor Up to four second-generation Intel Xeon Processor Scalable Family of processors, either Gold or Platinum level processors (formerly codename “Cascade Lake”). Supports processors up to 28 cores, core speeds up to 3.8 GHz, and TDP ratings up to 205W. Two processor sockets on the system board and two processors on the Processor and Memory Expansion Tray (standard on most models). Two Intel Ultra Path Interconnect (UPI) links at 10.4 GT/s each. Four processors are connected in a ring topology.
Chipset Intel C624 “Lewisburg” chipset
Memory Up to 48 DIMM slots (12 DIMMs per processor). Each processor has 6 memory channels, with 2 DIMMs per channel. Lenovo TruDDR4 RDIMMs, LRDIMMs and 3DS RDIMMs are supported. There are 24 DIMM sockets on the system board, and an additional 24 DIMM sockets on the processor and memory expansion tray (standard on most models).

DIMM slots are shared between standard system memory and persistent memory. DIMMs are available in three speeds: 2666 MHz, 2933 MHz and Performance+ 2933 MHz. Performance+ DIMMs support 2993 MHz with two DIMMs installed per channel (2DPC), whereas 2933 MHz DIMMs support 2933 MHz with only 1 DIMM per channel (1DPC).

Persistent memory Supports up to 24 Intel Optane DC Persistent Memory modules (DCPMMs) installed in the DIMM slots. Persistent memory is installed in combination with system memory DIMMs.
Memory maximums
  • With system memory DIMMs: Up to 6TB with 48x 128GB 3DS RDIMMs and four processors (1.5TB per processor)
  • With Persistent Memory in memory mode: Up to 12TB of Persistent Memory with 24x 512GB Intel Optane DC Persistent Memory modules and eight processors (3TB per processor)
  • With Persistent Memory in AppDirect mode: Up to 15TB total memory (12TB of Persistent Memory using 24x 512GB DCPMMs + 3TB of system memory using 24x 128GB 3DS RDIMMs and four processors) (3.75TB per processor)

Note: Support of more than 1TB per processor (more than 4TB for a 4-processor system) requires M-suffix or L-suffix processors with 2TB or 4.5TB memory support respectively. These calculations include any Persistent Memory installed. See the Processor options section for information.

Memory protection ECC, SDDC (for x4-based memory DIMMs), ADDDC (for x4-based memory DIMMs), memory mirroring, and memory sparing.

Network interfaces Integrated 10Gb Ethernet controller, based on the Intel Ethernet Connection X722. The server supports 1 of 6 available Phy adapters, providing either 2- or 4-port Gigabit Ethernet, 2- or 4-port 10 GbE with SFP+ connections or 2- or 4-port 10 GbE with RJ45 connections. One port can optionally be shared with the XClarity Controller (XCC) management processor for Wake-on-LAN and NC-SI support.
PCI Expansion slots Up to 9 PCIe slots plus a slot reserved for a LOM Ethernet adapter, plus a slot for the M.2 adapter. Six slots plus the LOM slot are on the system board and three (slots 3-5) are through a riser card. Three riser cards are available. All slots are available with two processors.
