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.
IBM Systems Director offers comprehensive systems management tools that help to increase
uptime, reduce costs, and improve productivity through advanced server management capabilities.
Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supported operating system.
Intel Trusted Execution Technology provides enhanced security through hardware-based resistance
to malicious software attacks, allowing an application to run in its own isolated space, protected
from all other software running on a system.
