ARM chips are well-suited for cold storage servers due to their low power consumption compared to x86 and PowerPC architectures. While x86, PowerPC and MIPS currently dominate, ARM adoption is accelerating, especially for storage where 80% of data is cold. This is due to disruptive influences like Open Compute and new ARM manufacturers. Using ARM can reduce infrastructure costs by 75% per rack and lower overall data center costs.

1. As Spartan power consumers ARM chips are the ideal
solution for cold storage servers compared to the sybaritic
power feasting of x86 and Power PC architectures .

Role of ARM Architecture
in the Datacenter

2. • Open Compute,
• Upstart Arm Processor Device Manufacturer
• Ability of major end-users to spec and build their own servers.

• While Power PC, x86 and MIPS, dominate now the adoption
particularly for storage will be quick because of disruptive influences

• The adoption of ARM Architecture in data center server applications
has moved from the slow to fast lane which will ultimately result in
lower costs for intelligent buyers.

3. Data Center Server Requirements
For Social Media and many other Cloud Solutions
• 80% of transactions are based on 20% of data that is
less than 6 weeks old
Current Dominant
Architectures Still Apply

5. Calxeda’s ARM-based processors
are a “Disruptive Force”
• Added Frank Frankovsky, Chairman of the Open Compute
Foundation, to its Board of Directors.

• It has partnered directly with not only traditional server
company's (HP and Dell) but also with contract manufacturers
directly such as Foxconn, Gigabyte and Aaeon
October 2013
• Its focused startup vision of bringing ultra low power solutions
give it advantages over the IC “giants”

6. The Genie is Out of The Bottle
• No doubt the push to ARM architecture is being driven by
specific companies, personalities and needs
• Corporate IT Buyers will benefit
• Broader Benefits of lowering overall infrastructure costs to
help bring Internet to All
Bill Kohnen
• Result will be immediate growth in use of ARM architecture
which will sustain further investment and growth.
