Inspur Rack Scale Server SR 4.5
Inspur Rack Scale Server SR 4.5: Rack Scale Architecture for
Hyperscale Datacenters
Inspur was the first server manufacturer to work on Project Scorpio design and
prototype with Baidu, Alibaba and Tencent (the BAT companies) in 2010 to meet
the demands of the hyperscale datacenter. The Inspur Rack Scale Server SR 4.5,
designed based on Scorpio specification V3.0, started mass production deployment in December 2012.
Today, Inspur is the leading supplier for Project Scorpio Rack Scale Servers.
Inspur builds and deploys the majority of the rack scale server platforms for Baidu and Alibaba
datacenters and captures over 60% of the rack scale server market in China.
The Inspur Rack Scale Server SR 4.5 proves to be the ideal platform for datacenter and cloud
deployments. Actual operation data from users is a powerful proof of outstanding performance
of Inspur Rack Scale Server SR 4.5 in energy consumption control, space optimization, compute
density and deployment speed: Inspur and Baidu
cooperated to set the highest record in deployment
speed in a single day - deployed 5000 Inspur Rack
Scale Server SR 4.5 nodes in a single day into Baidu
datacenter.
The actual measured data of the largest and the
most complicated online ticket booking system
12306 indicates that energy consumption of Inspur
Rack Scale Server SR 4.5 reduces by 15% compared
to conventional products, and reduces by 6% compared to conventional blade. Inspur Rack Scale Server SR 4.5 takes consideration of the overall
rack level system design, breaks through the standard restriction of conventional rack server
and cabinet - the depth of Inspur Rack Scale Server SR 4.5 is 47” and inner width of the rack is
21” (outer width is the same as conventional rack at 24”); the design allows the utilization rate
of overall space to increase by 31% to improve compute and storage density and provides many
possibilities for node design with over 10 node configurations to choose from.

Inspur Rack Scale Server SR 4.5 Architecture Overview
Inspur Rack Scale Server SR 4.5: Centralized Power, Cooling and Management at Rack Level:
Low TCO, High Power Efficiency

Flexible rack configuration: Inspur Rack Scale Server SR 4.5 can be customized with the
same node configuration cluster (i.e. for massive data storage/ Hadoop Cluster/Cloud
resources pools), or mix of different types of nodes in same Rack to enable running
multiple applications in the same Rack (i.e., web server/application server/file server/
GPU server/storage server).

Front IO, tool-less design for easy service and maintenance.
Strict hot aisle containment: Cold air comes from front
and hot air exhausts from rear.

RMC centralized management, monitoring, inspection
functions enhance deployment efficiency: Traditional
server standard deployment is 300 nodes/day. Inspur
Rack Scale Server SR 4.5 deployment is 60~105 Rack per
day/up to 5000 nodes per day.

Network Switches
Compatible with industry standard switches. Up to 6 switches per rack.
Central Power Bank
6x2500W PSU/customizable power redundancy, 208V 3 phase/dual feeds for USA datacenters. 12.5KW single
power bank standard per rack. Power Bank is customizable. Multiple power banks per rack is supported for
applications requiring higher power consumption, such as up to 4 power banks per rack/50KW for GPU rack.
Rack Level Cooling
Module
Up to 30 FANs, customizable cooling solutions, N+1 redundancy for each cooling group, rear tool-less
maintenance, front air inlet, rear air outlet
RMC: Rack Level
Management Module
Integrated RMC centralized management module in power bank, supporting status monitoring, log recording
and fault alarm and assets management of power supply, fan and node;
Rack Size
24”(W) x 47”(D) x83”(H) for 42U or 91”(H) for 46U
Reference Weight
1200KG / 2646 lbs
