Supports processors up to 144 cores, core speeds of up to 2.4 GHz, and TDP ratings of up to 330 W.

Memory

32 DIMM slots with two processors (16 DIMM slots per processor). Each processor has 8 memory channels, with 2 DIMMs per channel (DPC). Lenovo TruDDR5 RDIMMs are supported. DIMMs operate at up to 6400 MHz at 1 DPC and up to 5200 MHz at 2 DPC. Xeon 6500P and 6700P-series processors also support MRDIMMs up to 8000 MHz at 1 DPC (no support for 2 DPC). Xeon 6500P and 6700P-series processors also support up to 8x CXL 2.0 memory modules (4 per processor) installed in E3.S 2T drive bays.

Memory maximum

Up to 8TB by using 32x 256GB 3DS RDIMMs

Memory protection

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

Disk drive bays

AnyBay bays support SAS, SATA or NVMe drives. NVMe bays only support NVMe drives. Rear drive bays can be used in conjunction with 2.5-inch front drive bays. The server supports up to 12x NVMe drives all with direct connections (no oversubscription).

Storage controllers

Onboard NVMe ports with optional RAID support using Intel VROC NVMe RAID support using a Tri-mode RAID adapter 12 Gb SAS/SATA RAID adapters, PCIe 4.0 or PCIe 3.0 host interface 12 Gb SAS/SATA HBA (non-RAID), PCIe 4.0 or PCIe 3.0 host interface

Network interfaces

Two dedicated OCP 3.0 SFF slots with a PCIe 5.0 host interface, either x8 or x16. Support a variety of 2-port and 4-port adapters with 1, 10, 25 and 100 GbE network connectivity. One port of each installed OCP adapter can optionally be shared with the XClarity Controller (XCC) management processor for Wake-on-LAN and NC-SI support.

PCI Expansion slots

Up to 3x slots, all at the rear, plus 2 OCP slots. All slots are PCIe 5.0. Choices for rear-access slots: 3x PCIe 5.0 slots (1x full-height, 2x low-profile) 2x PCIe 5.0 slots (1x full-height, 1x low-profile) + 2x hot-swap M.2 drive bays 2x PCIe 5.0 slots (2x full-height) 1x PCIe 5.0 slot (1x full-height) + 2x hot-swap 2.5-inch drive bays With support for open-loop water cooling, rear slots are as follows: 2x PCIe 5.0 slots (1x full-height, 1x low-profile) 1x PCIe 5.0 slot (1x full-height) + 2x hot-swap M.2 drive bays For details of these configurations, see the I/O expansion for details. All configurations include at the rear of the server: 2x OCP slots with PCIe 5.0 x16 or x8 connection For 2.5-inch front drive configurations, the server supports the installation of a CFF RAID adapter or HBA in a dedicated area that does not consume any of the rear PCIe slots. Note: Some slots are not available in a 1-processor configuration. See the I/O expansion for details.

GPU support

Support for up to 3x single-wide GPUs

Cooling

Up to 8x N+1 dual-rotor or single-rotor hot-swap 40 mm fans, implemented as 2-in-1 fan modules. Fans are N+1 rotor redundant. Fan select is configuration dependent. There is also one fan integrated in each power supply. For customers with water infrastructure in their data center, the server also supports open-loop water cooling for efficient heat removal.

Power supply

Up to two hot-swap redundant AC power supplies, 80 PLUS Platinum or 80 PLUS Titanium certification. 800W, 1300W, 2000W AC options. All AC power supplies support 230V power; some also support 115V input supply. In China only, all power supply options support 240 V DC. Support for HVDC and -48V DC power supply options.

Systems management

Operator panel with status LEDs. Optional External Diagnostics Handset with LCD display. Clarity Controller 3 (XCC3) embedded management based on the ASPEED AST2600 baseboard management controller (BMC) and OpenBMC, XClarity One centralized infrastructure delivery, XClarity Integrator plugins, and XClarity Energy Manager centralized server power management. Optional XCC3 Premier to enable remote control functions and other features.

Dimensions

Width: 440 mm (17.3 in.), height: 43 mm (1.7 in.), depth: 788 mm (31 in.). Servers with E3.S front drives have a longer depth. drive See Physical and electrical specifications for details.

Selection qualification

CTO is a configuration base code, not a fixed installed BOM. Platform limits do not mean simultaneously installed CPU, RAM, drives or GPUs. Verify machine type, CPU count, memory, backplane, cooling and power. AI/HPC denotes an ordering scope, not included accelerators. Confirm local warranty and supply separately.
