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.
