• Large data-storage capacity and hot-swap capability
The server supports a maximum of eight 2.5-inch hot-swap or simple-swap Serial Attached SCSI (SAS)
or Serial ATA (SATA) hard disk drives, or four 3.5-inch hot-swap or simple-swap SAS/SATA hard disk
drives, depending on the server model.
• Large system-memory capacity
The server supports up to 32 GB if unbuffered DIMMs are installed. The memory controller supports error
correcting code (ECC) for up to 4 industry-standard PC3L-12800 (DDR3-1600), DDR3 (third-generation
double-data-rate), unbuffered dual inline memory modules (DIMMs).
• Mobile access to Lenovo 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 Lenovo
Service Information website. The Lenovo 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 Lenovo System x3250 M5 Type 5458 server" on page 1.
• Multi-core processing
The server supports Intel Pentium™, Intel Core™ i3, and IntelXeon E3-1200 v3 series multi-core
microprocessors. The server comes with one microprocessor installed.
• PCI adapter capabilities
The server has two PCI interface slots. Both slots can support PCI Express adapters. See "Replacing an
adapter" on page 185 for detailed information.
• Cooling and optional power capabilities
The server supports five speed-controlled simple-swap fans for a full configuration. The server comes
with one 300-watt fixed power supply, or one 460-watt hot-swap power supply installed. The server
supports a maximum of two 460-watt hot-swap power supplies. For redundancy support on hot-swap
models, two power-supplies must be installed in the server. Two power supplies enables continued
operation if one of the power supplies fails.
• 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. Additional optional RAID
adapters are available for purchase that provide RAID level 5.
• Systems-management capabilities
The server comes with an Integrated Management Module II (IMM2). When the IMM2 is used with the
systems-management software that comes with the server, you can manage the functions of the server
locally and remotely. The IMM2 also provides system monitoring, event recording, and network alert
capability. The systems-management connector for the IMM2 is located on the rear of the server.
• UEFI-compliant server firmware
The UEFI firmware offers several features, including Unified Extensible Firmware Interface (UEFI)
version 2.1 compliance, enhanced reliability, availability, and serviceability (RAS) capabilities, and basic
input/output system (BIOS) compatibility support. UEFI replaces the BIOS and defines a standard
interface between the operating system, platform firmware, and external devices. The server is capable of
booting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters
as well as UEFI-compliant adapters. For more information about UEFI-compliant firmware, go to
http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5083207.
