HP Innovations – Glossary (Gen8)
Term Definition
HP Smart Socket guide
The HP Smart Socket guide enables the addition or upgrade of processors without fear of bending pins that lead to motherboard failure
and replacement. Damaged pins are the most common cause for system board replacement.
HP SmartMemory
HP SmartMemory is a unique technology for ProLiant Gen8 servers that unlocks certain performance and power efficiency features. . It
enables ProLiant Gen8 systems to reliably identify and verify whether installed memory has passed HP’s qualification and test processes.
Because the memory is authenticated, extended memory features can be enabled through the system ROM. HP SmartMemory will
provide a platform to allow future memory-related support enhancements through HP Active Health System, System Insight Management
and Insight Control management software.
HP SmartDrives
Warns if attempt is made to remove the wrong drive in a RAID array set when drives are in rebuild mode. Avoids the #1 cause of data
loss due to manual error. ‘do not remove’ LED – which only lights up when the RAID array is compromised.
FlexibleLOM 1 GbE or 10GbE (LOM) Local Area Network on Motherboard.
Flex Fabric
Virtual Connect FlexFabric is an extension to Virtual Connect Flex-10 which leverages the new Fibre
Channel over Ethernet (FCoE) protocols. Used as an option for their implementation of BladeSystem
and Virtual Connect.
512MB FBWC Standard Flash-backed write cache improves disk write performance as data is temporarily stored in the write cache, which uses DRAM and is
substantially quicker when compared to the disk drive.
Intelligent Provisioning
Simple tool that automates server setup and configuration tasks, eliminating physical media such as CDs and DVDs. Includes pre-boot
display for early status and setup information that appears three seconds after power-up: guided, profile-driven or scripted approaches,
automatic updates for firmware and drivers.
Active Health System
Configuration changes logged in real time, accessible by a HP services professional for problem resolution. Stores the data required for
problem resolution, reducing time needed with support to reproduce or describe errors.
HP Agentless Management
Agentless monitoring provides ease-of-use, fast implementation and lowered maintenance costs and effort.
HP Smart Update
An automated system maintenance tool that systematically updates servers and blade infrastructures. It manages deployment of
firmware, drivers and tools to execute system updates in parallel across the infrastructure. Reduces complexity by
providing comprehensive discovery, analysis and compliance-oriented reporting. Updates can be scheduled, staged and deployed across
hundreds of servers in many different configurations.
3D Sea of Sensors
Sensors that enable: automatic tracking of IT assets; reduced energy use and increase power capacity by improving airflow efficiency;
automatic tracking of power usage per rack and server.
