“Using RDMA, NVMe over Fabrics (NVMe-oF) provides the high BW and low-latency characteristics of NVMe to remote devices. Moreover, these performance traits are delivered with negligible CPU overhead as the bulk of the data transfer is conducted by RDMA. In this session, we present an overview of NVMe-oF and its implementation in Linux. We point out the main design choices and evaluate NVMe-oF performance for both Infiniband and RoCE fabrics.”
Today SuperMicro rolled out a wide range of NVMe Flash server and storage systems with support for the new Intel Optane SSD DC P4800X based on 3D XPoint technology. “Being First-To-Market with the latest in computing technology continues to be our corporate strength, the addition of Intel Optane memory technology gives our top tier customers a new memory deployment strategy that provides better write performance and latency than existing NVMe NAND SSD solutions,” said Charles Liang, President and CEO of Supermicro. “In addition this new memory is slated to consume 30 percent lower max-power than SSD NAND memory, supporting our customer’s green computing priorities.”
The Second Workshop On Performance and Scalability of Storage Systems (WOPSSS) has issued its Call for Papers. The one-day workshop will be held jointly with ISC 2017 in Frankfurt, Germany. “The Workshop On Performance and Scalability of Storage Systems aims to present state-of-the-art research, innovative ideas, and experience that focus on the design and implementation of HPC storage systems in both academic and industrial worlds, with a special interest on their performance analysis. The arrival of new storage technologies and scales unseen in previous practice lead to significant loss of performance predictability. This will leave storage system designers, application developers and the storage community at large in the difficult situation of not being able to precisely detect bottlenecks, evaluate the room for improvement, or estimate the matching of applications with a given storage architecture.”
“The IO infrastructure of TSUBAME3.0 combines fast in-node NVMe SSDs and a large, fast, Lustre-based system from DDN. The 15.9PB Lustre* parallel file system, composed of three of DDN’s high-end ES14KX storage appliances, is rated at a peak performance of 150GB/s. The TSUBAME collaboration represents an evolutionary branch of HPC that could well develop into the dominant HPC paradigm at about the time the most advanced supercomputing nations and consortia achieve Exascale computing.”
Nikos Trikoupis from the City University of New York gave this talk at the HPC User Forum in Austin. “We focus on measuring the aggregate throughput delivered by 12 Intel SSD DC P3700 for NVMe cards installed on the SGI UV 300 scale-up system in the CUNY High Performance Computing Center. We establish a performance baseline for a single SSD. The 12 SSDs are assembled into a single RAID-0 volume using Linux Software RAID and the XVM Volume Manager. The aggregate read and write throughput is measured against different configurations that include the XFS and the GPFS file systems.”
Today One Stop Systems (OSS) introduced a pair of high-speed networked storage appliances that supports high-performance, shared storage services. “The OSS approach optimizes the hardware for the environment and optimizes the software for the application in the Flash Storage Array for Networks product line (FSAn). This hardware and software optimization in the FSAn product line provides the best ROI in any environment by minimizing hardware and license costs through advance array-level optimizations while maximizing the utilization of the flash array through VSI and VDI application support.”
Today One Stop Systems announced the 4U Flash Storage Array with Mangstor MX6300 NVMe SSDs. OSS’ FSAe-4 can accommodate 32 of the MX6300 providing up to 172TB of shared Flash storage. The FSAe-4 is a fully redundant, hot serviceable configuration with 4 independent 1U servers attached to the PCIe expansion chassis. The expansion system can support Ethernet (RoCE) or Infiniband fabrics and network speeds up to 100Gb/s.
“We’ve seen the rapid evolution of SSDs and have been contributing to the NVMe over Fabrics standard and community drivers,” said Michael Kagan, CTO at Mellanox Technologies. “Because faster storage requires faster networks, we designed the highest-speeds and most intelligent offloads into both our ConnectX-5 and BlueField families. This lets us connect many SSDs directly to the network at full speed, without the need to dedicate many CPU cores to managing data movement, and we provide a complete end-to-end networking solution with the highest-performing 25, 50, and 100GbE switches and cables as well.”
Today E8 Storage launched the storage industry’s first-ever centralized, highly available rack scale flash appliance based on Non-Volatile Memory express (NVMe) drives. The E8-D24 is the first array that combines the high performance of NVMe drives, the high availability and reliability of centralized storage, and the high scalability of scale-out solutions.
“We have partnered with Liqid to provide our customers with a leading option for enterprise-class flash storage. OSS is one of the only companies currently producing expansion products as dense as this FSA. By combining our PCIe expertise with Liqid’s PCIe flash storage and software expertise, we have created a state-of-the-art flash array that can provide fast response time, high-availability, and high-speed data processing in data centers, cloud environments, mega websites, and high-performance applications.”
