IBM System x3650 M4 3
The server has four integrated Gigabit Ethernet ports and two optional 10 Gb Ethernet ports with 
mezzanine cards that do not consume PICe slots.
The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum 
bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the previous 
generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding).
With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon 
processor E5 family. This integration helps to dramatically reduce I/O latency and increase overall 
system performance. 
Support for NVIDIA Quadro graphics processing units (GPUs) to maximize computing power
Availability and serviceability
The x3650 M4 provides many features to simplify serviceability and increase system uptime: 
The server offers memory mirroring and memory rank sparing for redundancy in the event of a 
non-correctable memory failure.
Tool-less cover removal provides easy access to upgrades and serviceable parts, such as CPU, 
memory, and adapter cards.
The server offers hot-swap drives, supporting RAID redundancy for data protection and greater 
system uptime.
The server has up to two redundant hot-swap power supplies and four hot-swap dual-motor redundant 
fans (two fan zones with an N+1 fan design) to provide availability for business-critical applications.
The light path diagnostics panel and individual light path LEDs quickly lead the technician to failed (or 
failing) components, which simplifies servicing, speeds up problem resolution, and helps improve 
system availability.
Predictive Failure Analysis (PFA) detects when system components (processors, VRMs, memory, 
HDDs, fans, and power supplies) operate outside of standard thresholds and generates proactive 
alerts in advance of a possible failure, therefore increasing uptime.
Solid-state drives (SSDs) offer significantly better reliability than traditional mechanical HDDs for 
greater uptime.
Built-in Integrated Management Module Version II (IMM2) continuously monitors system parameters, 
triggers alerts, and performs recovering actions in case of failures to minimize downtime.
Built-in diagnostics, using Dynamic Systems Analysis (DSA) Preboot, speed up troubleshooting tasks 
to reduce service time.
Three-year customer-replaceable unit and on-site limited warranty, 9x5 next business day. Optional 
service upgrades are available.
Manageability and security
Powerful systems management features simplify local and remote management of the x3650 M4:
The server includes an Integrated Management Module II (IMM2) to monitor server availability and 
perform remote management.
Integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, 
configuration, and updates, and simplifies error handling.
Integrated Trusted Platform Module (TPM) 1.2 support enables advanced cryptographic functionality, 
such as digital signatures and remote attestation.
Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
