The x222 provides many features to simplify serviceability and increase system uptime:
Chipkill, memory mirroring, and memory rank sparing for redundancy if there is a non-correctable
memory failure.
Tool-less cover removal provides easy access to upgrades and serviceable parts, such as processor,
memory, and adapters.
Use of optional 1.8-inch hot-swap drives allows for greater system uptime.
Support for RAID 1 across the two drives installed in a server, as of Flex System code base 1.3.2
(announced May 13, 2014).
A light path diagnostics panel and individual light path LEDs lead the technician to failed (or failing)
components. These features simplify servicing, speed up problem resolution, and help improve
system availability.
Predictive Failure Analysis (PFA) detects when system components (such as processors, memory,
and hard disk drives) operate outside of standard thresholds and generates proactive 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.
A built-in Integrated Management Module II (IMM2) continuously monitors system parameters,
triggers alerts, and performs recovery actions in case of failures to minimize downtime.
Built-in diagnostic tests using Dynamic Systems Analysis (DSA) Preboot speed 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 x222:
Each 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.
Integrated Trusted Platform Module (TPM) V1.2 support enables advanced cryptographic
functionality, such as digital signatures and remote attestation.
Industry-standard AES NI support for faster and stronger encryption.
Integrates with the IBM Flex System Manager™ for proactive systems management. It offers
comprehensive systems management for the entire Flex System platform, increasing uptime,
reducing costs, and improving productivity through advanced server management capabilities.
Fabric Manager simplifies the 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.
