Availability and serviceability
The x240 provides many features to simplify serviceability and increase system uptime:
Chipkill, 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.
Hot-swap drives supporting integrated RAID 1 redundancy for data protection and greater system

uptime.
A light path diagnostics panel and individual light path LEDs to 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), which detects when system components (such as processors,

memory, and hard disk drives) operate outside of standard thresholds and generates pro-active alerts
in advance of possible failure, therefore increasing uptime.
Solid-state drives (SSDs), which 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 recovering actions in case of failures 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 are available.
Manageability and security
Powerful systems management features simplify local and remote management of the x240:
The x240 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 AES NI support for faster, stronger encryption.

Integrates with the IBM® Flex System™ Manager for proactive systems management. It offers

comprehensive systems management for the entire Flex System platform that help to increase
up-time, reduce costs, and improve productivity through advanced server management capabilities.
Fabric Manager simplifies deployment of infrastructure connections by managing network and

storage address assignments.
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.
