The following table lists the standard specifications.
Table 1. Standard specifications (part 1)
Components
Specification
Form factor
2U rack.
Processor
Up to four Intel Xeon processor E5-4600 product family processors, each with eight cores (up to
2.7 GHz), six cores (up to 2.9 GHz), or four cores (up to 2.0 GHz). Two processor sockets on
the system board and two processors on the processor and memory expansion tray (standard
on most models). Two QPI links up to 8.0 GTps each. Up to 1600 MHz memory speed. Up to 20
MB L3 cache per processor.
Chipset
Intel C600 series.
Memory
Up to 48 DIMM sockets (12 DIMMs per processor). RDIMMs and LRDIMMs (Load Reduced
DIMMs) are supported, but memory types cannot be intermixed. The memory speed is up to
1600 MHz. There are 24 DIMM sockets on the system board. There are an additional 24 DIMM
sockets on the processor and memory expansion tray (standard on most models).
Memory
maximums
With RDIMMs: Up to 768 GB with 48x 16 GB RDIMMs and four processors,
With LRDIMMs: Up to 1.5 TB with 48x 32 GB LRDIMMs and four processors.
Memory
protection
ECC, Chipkill (for x4-based memory DIMMs), memory mirroring, and memory sparing.
Disk drive bays
Up to 16 2.5-inch hot-swap SAS/SATA bays or up to 32 1.8-inch hot-swap solid-state drive
(SSD) eXFlash bays. Drive bays can be in any combination of four 2.5-inch drives or eight
1.8-inch eXFlash SSD drives.
Maximum
internal storage
Up to 14.4 TB with 900 GB 2.5-inch SAS HDDs, up to 16 TB with 1 TB 2.5-inch NL SAS/SATA
HDDs, or up to 16 TB of SSDs using 512 GB 1.8-inch drives. An intermix of SAS/SATA is
supported.
RAID support
RAID 0, 1, 10 with integrated ServeRAID M5110e with LSI SAS2208 6 Gbps RAID on Chip
(ROC) controller. Optional upgrades to RAID 5 and 50 are available (zero-cache is 512 MB and
battery-backed cache is 512 MB or 1 GB flash-backed cache). There is an optional upgrade to
RAID 6 and 60 for a 512 MB or 1 GB cache.
Optical drive
bays
There is one bay for an optional Multiburner drive.
Tape drive bays None internal. Use a supported external tape drive.
Network
interfaces
Emulex BE3 controller with two standard integrated Gigabit Ethernet 1000BASE-T ports (RJ-45)
and two optional 10 Gb ports through an adapter in a dedicated slot. The 10 GbE options are
10Base-T dual port (copper) or SFP+ dual port (fiber).
PCI Expansion
slots
Up to eight slots, five on the system board, three on an optional riser card. The slots are as
follows:
Slot 1: PCIe 3.0 x8; full-height, half-length (optional with riser card, requires processor 2)
Slot 2: PCIe 3.0 x8; full-height, half-length (optional with riser card, requires processor 2)
Slot 3: PCIe 3.0 x8; full-height, half-length (optional with riser card, requires processor 2)
Slot 4: PCIe 3.0 x8; low profile (requires processor 2)
Slot 5: PCIe 3.0 x8; low profile (requires processor 2)
Slot 6: PCIe 3.0 x8; low profile
Slot 7: PCIe 3.0 x8; low profile
Slot 8: PCIe 3.0 x8; low profile
Slots 1, 2, and 3 are physically x16 slots.
