• Large system-memory capacity
The server can support up to 768 GB of system memory. The server provides 24 dual inline memory
module (DIMM) connectors. The server memory controller supports error correcting code (ECC) for
PC3-8500 (DDR3-1066), PC3-10600 (DDR3-1333), PC3-12800 (DDR3-1600), or PC3-14900 (DDR3-1866),
DDR3 (third-generation double-data-rate), synchronous dynamic random access memory (SDRAM)
DIMMs.
• Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more information about light
path diagnostics and the LEDs, see “Light path diagnostics” on page 171 and “Light path diagnostics
LEDs” on page 174.
• Mobile access to Service Information website
The server provides a QR code on the system service label, which is on the cover of the server, that you
can scan using a QR code reader and scanner with a mobile device to get quick access to the Service
Information website. The Service Information website provides additional information for parts installation
and replacement videos, and error codes for server support. For the QR code, see QR code information
on page Chapter 1 “The System x3650 M4 server” on page 1.
• Multi-core processing
The server supports up to two Intel Xeon™ E5-2600 series multi-core microprocessors. The server
comes with a minimum of one microprocessor.
• PCI adapter capabilities
The server has two PCI interface slots (one supports low-profile cards, and one supports half-length,
full-height cards). Slot 2 can support PCI Express or PCI-X adapters through an optional PCI riser card.
See “Replacing an adapter” on page 282 for detailed information.
• Redundant connection
The addition of the optional Ethernet adapter provides failover capability to a redundant Ethernet
connection with the applicable application installed. If a problem occurs with the primary Ethernet
connection and the optional Ethernet adapter is installed on the server, all Ethernet traffic that is
associated with the primary connection is automatically switched to the optional redundant Ethernet
adapter connection. If the applicable device drivers are installed, this switching occurs without data loss
and without user intervention.
• Redundant cooling and optional power capabilities
The server supports a maximum of two 550-watt, 750-watt, or 900-watt hot-swap power supplies
and four dual-motor hot-swap fans, which provide redundancy and hot-swap capability for a typical
configuration. The redundant cooling by the fans in the server enables continued operation if one of the
fans fails. The server comes with the minimum of one 550-watt, 750-watt, or 900-watt hot-swap power
supply and three fans.
You must install the fourth fan when you install the second microprocessor in the server. You can order
the second optional power supply for power redundancy.
Note: You cannot mix different wattages of power supplies in the server.
• ServeRAID support
The ServeRAID adapter provides hardware redundant array of independent disks (RAID) support to
create configurations. The standard RAID adapter provides RAID levels 0, 1, and 10. An optional RAID
adapter is available for purchase.
• Systems-management capabilities
The server comes with an integrated management module II (IMM2). When the IMM is used with the
systems-management software that comes with the server, you can manage the functions of the server
locally and remotely. The IMM also provides system monitoring, event recording, and network alert
capability. The systems-management connector on the rear of the server is dedicated to the IMM. The
