With ARM getting more OS support you can see the demand rising quickly. Calxeda plans to introduce 64-bit ARM processors for servers in 2014. The company's chip roadmap shows Calxeda’s third generation platform, code-named “Lago”, is Calxeda’s platform for the warehouse-scale datacenter. Built on the 64-bit ARMv8 architecture, Lago features Calxeda’s third generation scaling features, called the Calxeda Fleet Services, to further automate and optimize common operations at massive scale. The enhanced fabric will also connect hundreds of thousands of nodes, with quality of service features and the ability to allocate and control resources. Lago is set to become available in 2014.
“We expect to lead the industry with new concepts that will change the datacenter in ways far beyond just lowering power and increasing density. Lago will be in the first wave of 64-bit complete systems and application stacks on ARM in 2014, and we are collaborating with key partners to ensure that customers can ramp quickly with production-quality software and OS support for both Midway and Lago,” explained Mr. Evans.
To date Calxeda has shipped thousands of EnergyCore ECX-1000 SoCs to OEM customers and end users, which proves that there is a great interest towards ultra-low power architectures in datacenters. Numerous analysts believe that even 32-bit ARM-based server solutions may be disruptive for certain environments.
"64-bit ARM architecture-based production servers are years away. Calxeda's approach to shipping 32-bit technology today and upgrading to the ARM-A15 in 2013 makes a lot of sense for specialized workloads in the largest datacenters," said Patrick Moorhead, president and principal analyst at Moor Insights & Strategy.
