protection
Memory-channe
Optional on all models. eXFlash DIMMs are installed in memory DIMM slots, but are seen by
l storage
the OS as storage devices. Memory channels with eXFlash DIMMs must also have at least one
RDIMM. Cannot be mixed with LRDIMMs. A maximum of 32 eXFlash DIMMs can be installed.
Maximum 12.8 TB with 32x 400GB eXFlash DIMMs.

bays
Network
Mezzanine LOM (ML2) slot for dual-port 10 GbE cards with SFP+ or RJ-45 connectors or
interfaces
quad-port GbE cards with RJ-45 connectors. See Table 2. Dedicated 1 GbE port for systems
management.
PCI Expansion
Up to 22 PCIe slots plus two dedicated Mezzanine LOM slots. The slots are as follows:
slots
Four PCIe 3.0 x8 slots for internal RAID controllers (in two Storage Books)
Four PCIe 3.0 x16 slots (x16-wired), half length, full height (in two Primary I/O Books)
Two PCIe 3.0 x16 (x8-wired), half length, full height (in two Primary I/O Books)
Two ML2 slots for network adapter (PCIe 3.0 x8) (in two Primary I/O Books)
Four optional I/O Books, each with three slots, all full height (using two requires 6
processors; using all four requires 8 processors). Optional books are hot-swap capable.
Optional I/O Books can be either of the following options:
Half-length I/O Book: Two PCIe 3.0 x8 slots, one PCIe 3.0 x16 slot.
Full-length I/O Book: Two PCIe 3.0 x16, one PCIe 2.0 x4 slot; two aux power connectors:
150 W and 75 W. Supports one double-wide GPU up to 300 W.
Ports
Front: Four USB 3.0, two USB 2.0, and one DB-15 video ports. Rear: Eight USB 2.0, one DB-15
video, one DB-9 serial, and one 1 GbE RJ-45 IMM2 systems management. Internal: two USB
2.0 port for embedded hypervisor. The second video IMM2 and internal USB hypervisor ports
are used only when the server is partitioned into two four-socket servers.
