Memory options
The N3310 supports up to 128 GB of DDR4 memory. The storage server supports up to 8 DIMMs when one
processor is installed and up to 16 DIMMs when two processors are installed. Each processor has four
memory channels, and there are two DIMMs per channel.
The following rules apply when the memory configuration is selected:
The storage server supports RDIMMs only.
The maximum quantity of RDIMMs that can be installed in the storage server depends on the
number of processors.
All RDIMMs in the storage server operate at the same 1600 MHz speed, which is the maximum
memory speed that is supported by the Intel Xeon E5-2603 v3 processor.
The following memory protection technologies are supported:
ECC
Lockstep
Memory mirroring
Patrol scrubbing
Demand scrubbing
If lockstep or memory mirroring is used, RDIMMs must be installed in pairs (a minimum of one pair per
each processor), and both RDIMMs in a pair must be identical in type and size. Lockstep and memory
mirroring modes are mutually exclusive. Only one operational memory mode can be enabled on a storage
server, and it is a system-wide setting.
The following table lists the available memory options for the N3310.

Internal storage
The N3310 storage server supports up to 4x 3.5-inch SAS or SATA hot-swap drives (HDDs or SSDs). The
internal drives must be factory-configured (JBOD mode or RAID array), and they contain Windows Storage
Server 2012 R2 preload. For Relationship and TopSeller models, the internal drives are configured in a
RAID 0 or RAID 5 array (depending on the model; for more information, see Table 2 and Table 3).
The internal drives can be connected to the onboard Lenovo ThinkServer RAID 110i controller or Lenovo
ThinkServer RD350,RD450 RAID 710 PCIe Adapter.
The RAID 110i controller has the following specifications:
