A discussion of the Hyper-V Storage Quality of Service protocol (MS-SQOS) and updates to networked storage requirements for Windows Server 2016 virtual machine hosts. This session is targeted at engineers and product managers of providers of networked storage to Hyper-V hosts and anyone else interested in how Hyper-V hosts utilize storage.

This presentation covers QA methodologies when it comes to testing a Storage solution on the network level. The term "Multidimensional QA" derives from the diversity of Storage solutions which is a production of numerous factors being it software or hardware configurations. The role of the QA department is to select the right subset of the above factors which will best cover the range of relevant Storage solutions. Choosing right tools is yet another challenge. We will share The Visuality Systems’ QA discipline as well as tool reviews and, if time allows, some figures.

NFSv4 is a mature and stable protocol with many advantages over its predecessor NFSv3. This white paper focuses on the important issues that should be considered when migrating from an NFSv3 to NFSv4 environment.

Aberdeen delivers extreme computing power with our ultra-dense, extreme performance storage devices, packing over 3/4 Petabyte into only 4U of rack space. While consuming just 4U of rack space, Aberdeen’s ultra-dense storage devices suit a wide range of capacity hungry applications, including big data analytics or massive block or object storage

Internet changed the world and continues to revolutionize how people are connected, exchange data and do business. This radical change is one of the causes of the rapid explosion of data volume that required a new data storage approach and design. One of the common elements is that unstructured data rules the IT world. How famous Internet services we all use every day can support and scale with thousands of new users and hundreds of TB added daily and continue to deliver an enterprise-class SLA ?

This talk will provide an overview of scalable data management solutions in development and production at Los Alamos National Lab. The talk will target three primary efforts: MarFS, Marchive, and GUFI. MarFS is a near-POSIX scalable namespace over flexible data stores with a focus on data resiliency, metadata scalability, and IO shaping for efficient disk utilization. Marchive (MarFS archive) is a natural extension of the MarFS architecture for archival systems.

In this presentation we revisit NVMe-SSD disaggregation, using NVMe-over-Fabrics (NVMe-oF) as the remote storage protocol. We show that NVMe-oF reduces the overheads of remote access to a bare minimum, thus greatly increasing the efficiency and viability of NVMe disaggregation. Specifically, while recent works showed that SSD storage disaggregation via iSCSI degrades application-level throughput by 20%, we show negligible performance degradation with NVMe-oF.

Network File Systems, needed for accessing everything from low end storage, to Windows and Mac servers, to high end NAS, continue to evolve. NFS and SMB, the two dominant network storage protocols, also continue to improve with exciting new features in their most recent dialects. And the Linux clients continue to improve their implementation of these protocols, recently adding security and performance enhancements for SMB3 and new pNFS layout types along with the NFSv4.2 support in the NFS client.

Persistent Memory (PM) and Remote Direct Memory Access (RDMA) are hot buzzwords, especially when used in the same sentence. In this classic panel discussion RDMA experts from Intel, Mellanox and Microsoft will discuss the scope of the RDMA problems created by PM and contrast several approaches to addressing them.

With the excellent clustering, reliability, performance and security features brought by SMB3, there has been considerable interest in improving its ability to better support POSIX clients such as Linux, Unix, and Mac. Earlier presentations discussed the details of the proposed extensions. This panel discussion will encourage feedback and information exchange on additional requirements for better practical POSIX compliance using extensions to the SMB3 protocol.
