Description
4U server
• Height: 175.0 mm (6.9 inches)
• Width:
– With rack handles: 482.0 mm (19.0 inches)
– Without rack handles: 447.0 mm (17.6 inches)
• Depth: 765.9 mm (30.1 inches)
Note: The depth is measured with rack handles installed, but without the security bezel
installed.
39.8 kg (87.7 lb) in maximum.
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.
• Minimum: 16 GB
• Maximum:
– RDIMM: 1.5 TB
– LRDIMM: 3 TB
– 3DS-RDIMM: 6 TB
Note: Some types of GPU require the total installed memory to be less than 1 TB. For
specific types of GPU, see: https://support.lenovo.com/en/solutions/ht114952.
