Energy Efficiency - Lenovo System x3550 M4 Product Manual

The server offers hot-swap drives supporting RAID redundancy for data protection and greater system
uptime.
The server has two redundant hot-swap power supplies and six dual-motor hot-swap redundant fans
(two fan zones with N+1 fan design) to provide availability for business-critical applications.
The power source-independent light path diagnostics panel and individual light path LEDs quickly lead
the technician to failed (or failing) components. This simplifies servicing, speeds up problem resolution,
and helps improve system availability.
Predictive Failure Analysis (PFA) detects when system components (processors, VRMs, memory, hard
disk drives, fans, and power supplies) operate outside of standard thresholds and generates proactive
alerts in advance of possible failure, therefore increasing uptime.
Solid-state drivers (SSDs) offer significantly better reliability than traditional mechanical HDDs for
greater uptime.
Built-in Integrated Management Module II (IMM2) continuously monitors system parameters, triggers
alerts, and performs recovery actions in case of failure, to minimize downtime.
Built-in diagnostics using Dynamic Systems Analysis (DSA) Preboot speeds up troubleshooting tasks to
reduce service time.
Three-year customer replaceable unit and onsite limited warranty, next business day 9x5. Optional
service upgrades available.
Manageability and security
Powerful systems management features simplify local and remote management of the x3550 M4:
The server includes an Integrated Management Module II (IMM2) to monitor server availability and
perform remote management.
An integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup,
configuration, and updates, and simplifies error handling.
An integrated Trusted Platform Module (TPM) 1.2 support enables advanced cryptographic functionality
such as digital signatures and remote attestation.
There is industry-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 supporting 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.

Energy efficiency

The x3550 M4 offers the following energy-efficiency features to save energy, reduce operational costs,
increase energy availability, and contribute to a green environment:
Energy-efficient planar components help lower operational costs.
The x3550 M4 is Energy Star 2.0 compliant. Energy Star is the trusted, US government-backed symbol
for energy efficiency, with the goal of helping customers save money and protect the environment
through energy efficient products and practices.
High-efficiency 550 W and 750 W power supplies with 80 PLUS Platinum certification. Available 750 W
dc power supply option.
The Intel Xeon processor E5-2600 v2 product family offers significantly better performance over the
previous generation, while fitting into the same TDP limits.
Intel Intelligent Power Capability powers individual processor elements on and off as needed, to reduce
power draw.
