64 GB LR-DIMMs
v
Supports l.35-volt registered DIMMs (see “Installing a memory module”
on page 47 for more information)
v
The server also supports 200 GB and 400 GB eXFlash DIMMs that you
can install in unused DIMM slots to increase high performance storage
capabilities.
Drive expansion bays (depending on the model):
v
The server supports up to sixteen, drives (depending on the drive
backplane configuration) per 4-socket system. The following types of
drives are supported:
– l.8-inch hot-swap Serial Attached SCSI (SAS) solid state drives (SSD)
– 2.5-inch hot-swap Serial Attached SCSI (SAS) hard disk drives (HDD)
and solid state drives (SSD)
PCI expansion slots (depending on your model):
The server provides up to twelve PCIe adapter slots (with two I/O books
installed), as listed below:
v
The base system provides the following slots:
– Two x16 full-height slots, Gen3, 16 lanes wired (PCIe Gen3, x16)
– One x16 full-height slot, Gen3, 8 lanes wired (PCIe Gen3, x16 (8, 4, 1)
– Two x16 low-profile host bus adapter slots in the Storage book, Gen3,
8 lanes wired each (PCIe Gen3, x16 (8, 4, 1)
– One x8 Gen3 dedicated ML adapter slot, 8 lanes wired (non-standard
PCIe connector)
v
The optional half-length I/O book provides the following slots:
– One x16 full-height slot, Gen3, 16 lanes wired (PCIe Gen3, x16)
– Two x8 full-height slots, Gen3, 8 lanes wired each (PCIe Gen3, x8)
v
The optional full-length I/O book provides the following slots:
– Two x16 full-height slots, Gen3, 16 lanes wired each (PCI3 Gen3, x16)
