== Equipment Overview ==
The EHL consists of a two dual-thermal-zone (cold/hot) rackmount cabinet cabinets with power conditioning and backup, power distribution, thermal monitoring, and 1- and 10-gigabit network services. This cabinet These cabinets supports a large number of hyperscale and SOC-based ARM computers for various applied research projects.
== Equipment Detail ==
Cabinet 1 is equipped with a 15" 4:3 LCD monitor, bolted to a 4u blanking panel. This display is driven by a Raspberry Pi, and can be used to show educational information about the rack, current system status information, or diagnostic data.
<!-- === Calxeda/Boston Viridis ARM System ===
32-bit ARM compute is provided by a Calxeda Energy Core ECX-1000 system from Boston Limited. There are three installed "Energy Cards", each with 4 ECX-1000 nodes, which each have a quad-core ARM Cortex-A9 processor and a small (Cortex-M) ARM management processor. This system runs the [[Pidora]] build system (except for the Koji hub and web nodes).-->
=== 64-Bit ARM Compute ===
The EHL has over 100 cores of ARM64 compute, provided by a number of computers from multiple vendors. These computers provide a build system and testing platforms for software optimization, and are used for applied research on ARM64 systems.
== Funding ==
Select systems within EHL are accessible to both open source community members and to students when they are not in use for other OSTEP research.
<!-- === Pidora Koji System ===
=== Student Access ===
Students in [[SPO600]] and [[SBR600]] are given remote access to some EHL ARM computers for specific projects and labs, when they are not being used for OSTEP applied research projects.
