Introduction 

The initial Hewlett Packard Enterprise (HPE) G2 Rack product introduction includes HPE G2 Advanced Racks, announcement of the next 
generation of HPE Standard Series G2 Basic Power Distribution Units (PDUs), and the HPE Infrastructure Architect application to help you 
identify the best HPE Rack and Power Infrastructure products for your data center configuration. HPE G2 Advanced Series Racks will continue to 
use pre-existing rack accessories with the exception of several new accessory kits including: side panels, grounding kit, baying kit, stabilization kit, 
and roof-mount fan kits.   

HPE G2 Racks redefines intelligent infrastructure design for the mid-size business and provides a better foundation for the IT of the future. An 
intelligent datacenter does more for your business in less time and for less money. HPE has reimagined intelligent infrastructure design from the 
ground up and identified five business challenges that present opportunities for improved infrastructure to drive better business practices:  

 

 Safety and security 

 

 User experience 

 

 Power and cooling efficiency 

 

 Datacenter optimization 

 

 Interoperability  

HPE G2 Rack design 

The HPE G2 Rack product family was designed to address these business challenges in the following ways: 

Safety and security 

HPE G2 Rack and Power infrastructure is positioned to address existing and evolving security threats. Provisions for third-party locking solutions 
(biometric, electronic, and keyed) keep your servers where they belong (you can read more about these capabilities in the “Levels of rack 
security” s
ection). HPE also offers locking IEC power cords that lock to, both, the power distribution unit (HPE G2 units only) and to the target 
device (server, storage, or networking hardware) regardless of make or model.  

User experience 

The HPE user experience is assured through the available tools that provide information to guide your choices and the strength of HPE Rack 
and Power infrastructure to provide you with unmatched performance and reliability. The HPE Infrastructure Architect application (found at 
hpe.com/info/rackandpower) guides you to the right products based on your workload, budget, and location. And then HPE Power Advisor helps 
you plan how much power you’ll use month-to-month based on your planned or existing infrastructure. Toolless installation, low-profile PDUs, 
and improved cable management provisions get your new infrastructure up and running faster, whether it’s out-of-the-box or finding and fixing a 
problem during mid-lifecycle. If you’d prefer to purchase everything assembled and ready to go, our Factory Express option builds the industry’s 
best datacenter solutions on the industry’s best racks, and ships it directly to your door. 

Power and cooling efficiency 

Power costs are the number one operating expense for most IT infrastructures. And of course, the more power servers consume, the hotter they 
get.  HPE PDUs can safely operate in ASHRAE A1 – A4 environments up to 60 degrees Centigrade (that’s 10 degrees above industry standard), 
and 80% front-door open perforation on our racks (16% higher than the industry leader) allows for greater airflow that helps to minimize cooling 
costs. 

Datacenter optimization 

Datacenter space is often at a premium, and less room spent on infrastructure means more room for compute. HPE G2 Rack infrastructure is 
Intelligent, efficient datacenter infrastructure that deploys faster and in less space than existing infrastructures, leaving more room for compute 
and boosting your servers, storage, and networking capabilities. 

HPE G2 Rack infrastructure is taller and wider with deeper racks, while maintaining the same, industry-leading durability guaranteed with a 10-
year warranty. HPE PDUs have been redesigned and utilize toolless installation with more outlets per rack U than any competitor.
