课程名称：VMware vSAN：部署与管理 V7 概述：本课程将深入讲解VMware vSAN的核心概念，包括混合和全闪存架构、存储策略的创建、如何构建vSAN集群，以及vSAN如何处理故障等多个重要主题。VMware vSAN（前身为Virtual SAN）是一款超融合的软件定义存储（SDS）产品，由VMware开发，能够将VMware vSphere集群中的直接附加存储设备汇聚在一起，形成一个分布式的共享数据存储。用户可以定义虚拟机（VM）的存储需求，如性能和可用性，而vSAN确保这些策略的实施和维护。 vSAN是VMware ESXi内核的一部分，运行在来自各大原始设备制造商（OEMs）的行业标准x86服务器上，包括思科、Dell EMC、惠普企业、富士通、联想和超微等。由于vSAN是原生组件，因此不需要额外的软件，用户只需几次点击即可启用。 VMware vSAN的分布式架构确保存储策略的参数可以在虚拟机工作负载需求的变化或硬件、网络故障时得到执行。vSphere Web Client用于处理集群管理和存储策略实施。vSAN支持混合以及全闪存配置，采用两层架构。两种配置均包含一个缓存层和一个容量层。缓存层由每台主机的至少一块闪存设备组成，容量层则由每台主机的至少一块闪存设备（针对全闪存）或一块磁盘（针对混合）组成。vSAN将主机的存储资源结合为一个高性能的共享数据存储，供集群中的所有主机使用。 重要特性：VMware vSAN包括多个关键特性，虽然根据许可证类型不同，功能集有所差异。vSAN的主要特性包括基于存储策略的管理、伸缩集群、校验和以及无需自加密驱动器（SEDs）的软件定义数据静态加密等。vSAN 6.6声称比之前版本提高了50%的IOPS，因为它通过使用服务器端闪存设备来减少存储延迟。此外，它还包含新的健康检查功能，使管理员能够一目了然地查看vSAN集群的健康状况，并在检测到问题时帮助诊断。 vSAN集群可以包含2到64个节点。vSAN 6.6企业许可提供了具有本地站点保护的伸缩集群和旨在实现高可用性和安全性的原生数据静态加密，且CPU开销最小。高级及企业许可证支持去重、压缩和纠删码数据服务，适用于全闪存配置。纠删码可以配置为单重或双重奇偶校验以防止磁盘故障。所有vSAN许可证还支持存储质量服务（QoS），允许管理员限制特定VM所能消耗的IOPS数量。 如有任何问题或需要帮助，请通过我的LinkedIn联系我。
You will learn about vSAN concepts like Hyrbird and All-Flash architectures, Storage Policies, how to create a vSAN cluster, how vSAN handles failures, and much much more.*** if you have any questions or need help you can contact me over my LinkedIn ***VMware vSAN (formerly Virtual SAN) is a hyper-converged, software-defined storage (SDS) product developed by VMware that pools together direct-attached storage devices across a VMware vSphere cluster to create a distributed, shared data store. The user defines the storage requirements, such as performance and availability, for virtual machines (VMs) on a VMware vSAN cluster and vSAN ensures that these policies are administered and maintained.vSAN is part of the VMware ESXi kernel and runs on industry-standard x86 servers from original equipment manufacturers (OEMs), including Cisco, Dell EMC, Hewlett Packard Enterprise, Fujitsu, Lenovo and Supermicro. Because vSAN is a native component, it does not require additional software, and the user can enable it with a few clicks.The distributed architecture of VMware vSAN enables the parameters of the storage policy to be enforced despite changes in virtual machine (VM) workload demands or hardware or network failures. The vSphere Web Client handles cluster administration and storage policy implementation.vSAN supports both hybrid and all-flash configurations using a two-tier architecture. Both configurations use a caching tier and a capacity tier. The caching tier is composed of at least one flash device per host. The capacity tier is composed of at least one flash device (for all-flash) or one magnetic disk (for hybrid) per host. vSAN combines the host's storage resources into a single, high-performance, shared data store that all the hosts in the cluster can use.Important featuresVMware vSAN includes a number of key features, although the feature set varies depending on the license type. Some of vSAN's key features are Storage Policy-Based Management, stretched clusters, checksum and software-defined data-at-rest encryption which does not require self-encrypting drive (SEDs).vSAN 6.6 claims to deliver 50% more IOPS than previous versions of vSAN because of the way it minimizes storage latency through the use of server-side flash devices. It also includes a new health check feature that enables the administrator to see at a glance whether or not the vSAN cluster is healthy and, if it detects a problem, help diagnose the issue.A vSAN cluster can include between 2 and 64 nodes. The vSAN 6.6 Enterprise license offers stretched clusters with local site protection, and native data-at-rest encryption designed to achieve higher availability and security with minimal CPU overhead. Both Advanced and Enterprise licenses support deduplication, compression and erasure coding data services for all-flash configurations. Erasure coding can be configured with either single or double parity protection against disk failures.All the vSAN licenses also offer support for storage quality of service (QoS), which enables an administrator to place limits on the number of IOPS that specific VMs can consume.
