Important terminology
• In-band update. The installation or update is performed using a tool or application within an operating
system that is executing on the server's core CPU.
• Out-of-band update. The installation or update is performed by the Lenovo XClarity Controller collecting
the update and then directing the update to the target subsystem or device. Out-of-band updates have no
dependency on an operating system executing on the core CPU. However, most out-of-band operations
do require the server to be in the S0 (Working) power state.
• On-Target update. The installation or update is initiated from an Operating System executing on the
server's operating system.
• Off-Target update. The installation or update is initiated from a computing device interacting directly with
the server's Lenovo XClarity Controller.
• UpdateXpress System Packs (UXSPs). UXSPs are bundled updates designed and tested to provide the
interdependent level of functionality, performance, and compatibility. UXSPs are server machine-type
specific and are built (with firmware and device driver updates) to support specific Windows Server, Red
Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) operating system distributions.
Machine-type-specific firmware-only UXSPs are also available.
