SMB3 is the default Windows and MacOS X file sharing protocol, but what about making it the default on Linux ? After developing the UNIX extensions to the SMB1 protocol, the Samba developers are planning to add UNIX extensions to SMB3 also. Co-creator of Samba Jeremy Allison will discuss the technical challenges faced in making SMB3 into a seamless file sharing protocol between Linux clients and Samba servers, and how Samba plans to address them. Come learn how Samba plans to make NFS obsolete (again :-) ! Learning Objectives: 1) SMB3; 2) Linux; 3) Windows interoperability.

For years, enterprises have desired a way to ensure that an application will operate properly at scale on a particular storage array and network infrastructure, and increasingly, ensure that multiple applications can safely run at capacity on an all-flash or hybrid architecture. Companies need an approach that enables users to reference detailed workload analysis profiles as they build and share workload models, and simulate performance across a variety of vendors, products and technologies. Learning Objectives: 1) How to determine what the traffic related to an enterprise application implementation looks like from the perspective of the network infrastructure between application servers and storage arrays; 2) How the application I/O workload can be modeled to accurately represent the application in production using storage analytics or vendor performance statistics to generate a synthetic workload model; 3) How a statistical application model can be used to validate both array and network performance at varying traffic levels and rates to rapidly test if/then scenarios; 4) How multiple application models can be combined to determine appropriate throughput and response time levels on a given array; 5) How using these models can enable engineers and architects to cost-effectively test and confidently deploy new networked storage infrastructure.

With a design started in 2006, OpenIO is a new flavor among the dynamic object storage market segment. Beyond Ceph and OpenStack Swift, OpenIO is the last coming player on that space. The product relies on an open source core object storage software with several object APIs, file sharing protocols and applications extensions. The inventors of the solution took a radical new approach to address large scale environment challenges. Among them, the product avoids any rebalance like consistent hashing based systems always trigger. The impact is immediate as new machines contribute immediately without any extra tasks that impact the platform service. OpenIO also introduces the Conscience, an intelligent data placement service, that optimizes the location of the data based on various criteria such nodes workload, storage space. OpenIO is fully hardware agnostic, running on commodity x86 servers promoting a total independence.

A tutorial on using the open source persistent memory (PMEM) programming library offered at pmem.io; including examples providing power-fail safety, while storing data on PMEM. Programming examples will zero in on pmem.io’s transactional object store (i.e. “libpmemobj”) library, which is layered on the SNIA NVM Programming Model. The examples covered will demonstrate proper integration techniques, macros, C API, key theory concepts, terminology, and present in depth overview of what the library offers for PMEM programming initiatives. Learning Objectives: 1) Overview of persistent memory programming; 2) Close examination of the transactional object store library (libpmemobj); 3) Code integration walkthrough.
