Machine types

7X69 - 3 year warranty

Form factor

4U 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.

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).

Chipset

Intel C624 "Lewisburg" chipset

* RAID 930-16i or 940-16i with 4GB or 8GB flash-backed cache supports RAID 0, 1, 10, 5, 50, 6, 60

* 12 Gb SAS/SATA non-RAID: * 430-8i or 440-8i HBAs
* 430-16i or 440-16i HBAs

Network Interface

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 11 PCIe slots plus a slot reserved for a LOM Ethernet adapter, plus a slot for the M.2 adapter. Four slots (slots 4, 10, 11&
12) are on the system board and three slots (slots 5-7) are through a lower riser card. Slots 1 & 2 and 14 & 15 are via upper
riser cards that connect through slots 3 and 13 respectively. Slots 1-13 available with 2 processors; slots 14 & 15 require 4
processors.
The slots are as follows:
* Slot 1-2: Riser card slots (choice of x8/x8 or x16) (FHFL)
* Slot 3: Riser slot to enable slots 1 & 2 in the PCIe Expansion Tray (PCIe 3.0 x16)*
* Slot 4: PCIe 3.0 x8 (low profile)
* Slot 5-7: Riser card slots (choices are x8/x8/x8, x8/x8/x8ML2 and x8/x16ML2)
* Slot 8: PCIe 2.0 x2 / 6 Gb SATA slot reserved to M.2 adapter and drives
* Slot 9: Reserved for Ethernet LOM phy adapter
* Slot 10: PCIe 3.0 x8 (low profile)
* Slot 11: PCIe 3.0 x8 (low profile)
* Slot 12: PCIe 3.0 x8 (low profile)
* Slot 13: Riser slot to enable slots 14 & 15 in the PCIe Expansion Tray (PCIe 3.0 x16)*
* Slot 14-15: Riser card slots (choice of x8/x8 or x16) (FHFL)

* Slots 3 and 13 are used as riser slots to enable slots 1, 2, 14 and 15 in the PCIe Expansion Tray. It is also supported to have
the PCIe Expansion Tray installed with only one riser installed. For example, it is supported to have a riser card in slot 3 but
not in slot 13; slot 13 can then be used as a PCIe x16 slot.

Ports

Front: One VGA video port. Two USB 2.0 ports or one USB 2.0 and one USB 3.0 port, model dependent. The first USB 2.0 port can be
configured to support local systems management by using the XClarity Administrator mobile app on a mobile device connected via a
USB cable.
Rear: Two USB 3.0 ports, one VGA video port, one DB-9 serial port, and one RJ-45 XClarity Controller (XCC) systems management
port. The serial port can be shared with the XCC for serial redirection functions.
Internal: Optional M.2 adapter in dedicated slot supporting one or two M.2 drives (for OS boot support, including hypervisor
support).

Cooling
