Many traditional physical storage workloads are well understood. Quantifying how access patterns change when a hypervisor in inserted in between server applications and physical storage requires rethinking what is optimal for a NAS configuration. This presentation will examine several Hyper-V workloads from the perspective of an SMB3 implementer.

Platform as a Service (PaaS) offerings, like the Apple Newton, launched at a time when technology had not matured to the point necessary to cross the chasm to the early majority and into mass markets. Successes did exist, but were limited to specialized applications already targeted at a vendor’s existing platform. Infrastructure as a Service (IaaS), and its successor of software defined entities, are necessary intermediate steps towards decoupling application development from operational overhead.

Much effort has been invested recently in clustered SMB/CIFS solutions, however many environments still require high connection scalability from a single host or device. This session will present the architecture used by Likewise-CIFS, the SMB file server component of the Likewise Open project, to achieve more than 50,000 simultaneous client connections hosted by a single 4-way SMP host configured with 8 Gb of RAM. Attendees will also be introduced the freely available connection stress utility developed as part of Likewise Open.

The Likewise CIFS server is a new introduction to the Likewise Open project sponsored by Likewise Software. This new code base is released under a combination of the GNU LGPLv2.1+ and GPLv2+ licenses. This session explains the architecture of the Likewise IO manager and related processes, provide code walk through of the relevant drivers, and explain how the IO paths can be customized for specific storage platforms.
