SoftLayer has advanced its backend systems, upgrading its fully redundant data warehouse storage arrays and adding an application layer processing cluster to enable a Service Oriented Architecture (SOA). The data warehouse expansion included the installation of multi-petabyte storage arrays from EqualLogic (now Dell) in its Dallas, Seattle, and, when launched, Washington D.C. facilities to serve as the backend data storage powering all of SoftLayer's on-demand service offerings. Servers from SuperMicro provide the processing power for the new SOA infrastructure.
