vSAN Beyond The Basics

This session tells the VMware Virtual SAN story. It includes some of the basics and what is new for VSAN 6.2.

VMware NSX provides a platform for deployment of software-defined network (SDN) and network function virtualization (NFV) services across physical network devices in a way that is analogous to server virtualization.

1) The document discusses using VXLAN, BGP and EVPN to implement a layer 3 network for a cloud deployment using Ceph and CloudStack. This allows scaling beyond the limits of layer 2 networks and VLANs. 2) Key infrastructure components discussed include Dell S5232F-ON switches running Cumulus Linux, SuperMicro hypervisors and Ceph storage servers using NVMe SSDs. 3) The deployment provides high performance private and public cloud infrastructure with scalable networking and over 650TB of reliable Ceph storage per rack.

We are observing different network throughputs on Intel X710 NICs and QLogic FastLinQ QL41xxx NIC. ESXi hardware supports NIC hardware offloading and queueing on 10Gb, 25Gb, 40Gb and 100Gb NIC adapters. Multiple hardware queues per NIC interface (vmnic) and multiple software threads on ESXi VMkernel is depicted and documented in this paper which may or may not be the root cause of the observed problem. The key objective of this document is to clearly document and collect NIC information on two specific Network Adapters and do a comparison to find the difference or at least root cause hypothesis for further troubleshooting.

1. A distributed switch functions as a single virtual switch across all associated hosts and is configured in vCenter Server at the data center level. It consists of a control plane in vCenter Server and I/O planes in the VMkernel of each ESXi host. 2. Key components of a distributed switch include distributed ports, uplinks, and port groups. Distributed ports can connect VMs or VMkernel interfaces. Uplinks associate physical NICs across hosts. Port groups define connection configurations. 3. Configuring a distributed switch involves adding the switch in vCenter Server, creating distributed port groups, and defining properties like uplink ports and multicast filtering mode. This provides a consistent network configuration template across

The document provides an introduction to VMware vSphere distributed switches. It lists the benefits of distributed switches over standard switches, describes the distributed switch architecture, and discusses how to create, manage, and configure distributed switches and their properties. It also covers topics like distributed port groups, VMkernel networking, NetFlow, private VLANs, and troubleshooting distributed switch issues.

This document summarizes a talk given by Dave Voutila about hardening emulated devices in OpenBSD's vmd hypervisor. The talk discusses how vmd currently uses a single process model that shares memory between the hypervisor and VMs, presenting security risks. It proposes moving to a multi-process model where each VM is launched via fork and exec to isolate it and remove leftover state. This would help prevent guest-to-host escapes by isolating device emulation and limiting information leaks between VMs. Some initial benchmarks show the changes have little performance impact on disk and network I/O. Future work is planned to further isolate guest memory and expand device support.

This document summarizes a presentation about SUSE Linux Enterprise High Availability Cluster Multi-Device. It discusses the main features of SUSE HA including policy driven clusters, cluster aware filesystems, and continuous data replication. It then describes the HA storage stack architecture and various options for doing HA storage including DRBD, clustered LVM2, and Cluster-MD. Cluster-MD is presented as a software-based RAID storage that provides redundancy at the device level across multiple nodes. Performance comparisons show Cluster-MD outperforming clustered LVM mirroring. Extensions to Cluster-MD are discussed including expanding the size of a Cluster-MD device.

Third Workshop on Accelerator Programming Using Directives (WACCPD2016, co-located with SC16) While GPUs are increasingly popular for high-performance computing, optimizing the performance of GPU programs is a time-consuming and non-trivial process in general. This complexity stems from the low abstraction level of standard GPU programming models such as CUDA and OpenCL: programmers are required to orchestrate low-level operations in order to exploit the full capability of GPUs. In terms of software productivity and portability, a more attractive approach would be to facilitate GPU programming by providing high-level abstractions for expressing parallel algorithms. OpenMP is a directive-based shared memory parallel programming model and has been widely used for many years. From OpenMP 4.0 onwards, GPU platforms are supported by extending OpenMP’s high-level parallel abstractions with accelerator programming. This extension allows programmers to write GPU programs in standard C/C++ or Fortran languages, without exposing too many details of GPU architectures. However, such high-level parallel programming strategies generally impose additional program optimizations on compilers, which could result in lower performance than fully hand-tuned code with low-level programming models.To study potential performance improvements by compiling and optimizing high-level GPU programs, in this paper, we 1) evaluate a set of OpenMP 4.x benchmarks on an IBM POWER8 and NVIDIA Tesla GPU platform and 2) conduct a comparable performance analysis among hand-written CUDA and automatically-generated GPU programs by the IBM XL and clang/LLVM compilers.

http://adl.tw/~jeremy/slides/presentation2.pptx Attached detailed Analysis of CVE-2013-2094 (&on x86-32). Exploit the CVE-2013-2094 with animation There have been more vulnerabilities in the Linux Kernel in 2013 than there had been in the previous decade. In this paper, the research was focused on defending against arbitrary memory overwrites in Privilege Escalation. To avoid malicious users getting root authority. The easiest way is to set the sensitive data structure to read-only. But we are not sure the sensitive data structure will never be modified by legal behavior from a normal device driver; thus, we posed a compatible solution between read-only solutions and writable solutions to enhance compatibility. The main idea that we posed not only solves the above problem, but also the general problem which is ensuring that important memory values can only be changed within a safe range. It is not just set to read-only. Key Word : Linux Kernel Vulnerabilities、exploit、Privilege Escalation

Locating objects in images (“detection”) quickly and efficiently enables object tracking and counting applications on embedded visual sensors (fixed and mobile). By 2012, progress on techniques for detecting objects in images – a topic of perennial interest in computer vision – had plateaued, and techniques based on histogram of oriented gradients (HOG) were state of the art. Soon, though, convolutional neural networks (CNNs), in addition to classifying objects, were also beginning to become effective at simultaneously detecting objects. Research in CNN-based object detection was jump-started by the groundbreaking region-based CNN (R-CNN). We’ll follow the evolution of neural network algorithms for object detection, starting with R-CNN and proceeding to Fast R-CNN, Faster R-CNN, “You Only Look Once” (YOLO), and up to the latest Single Shot Multibox detector. In this talk, we’ll examine the successive innovations in performance and accuracy embodied in these algorithms – which is a good way to understand the insights behind effective neural-network-based object localization. We’ll also contrast bounding-box approaches with pixel-level segmentation approaches and present pros and cons.

This talk will start with brief introduction to streaming processing and Flink itself. Next, we will take a look at some of the most interesting recent improvements in Flink such as incremental checkpointing, end-to-end exactly-once processing guarantee and network latency optimizations. We’ll discuss real problems that Flink’s users were facing and how they were addressed by the community and dataArtisans.

1. The document discusses various architectures for running Kafka in a multi-datacenter environment including running Kafka natively in multiple datacenters, mirroring data between datacenters, and using hierarchical Zookeeper quorums. 2. Key considerations for multi-DC Kafka include replication settings, consumer reconfiguration needs during outages, and handling consumer offsets and processing state across datacenters. 3. Native multi-DC Kafka is preferred but mirroring can be an alternative approach for inter-region traffic when latency is over 30ms or datacenters cannot be combined into a single cluster. Asynchronous mirroring acts differently than a single Kafka cluster and impacts operations.
