本课程是 VMware vSphere 6.0 系列的第四部分，重点关注集群、补丁管理和性能优化。 **核心内容包括：** * **DRS 集群 (Distributed Resource Scheduling):** 学习如何动态平衡虚拟机的 CPU 和内存资源，通过自动迁移避免资源压力。还将介绍增强型 vMotion 兼容性 (EVC)，允许混合不同代数的 ESXi 主机。 * **HA 集群 (High Availability):** 掌握如何通过 HA 集群最小化因 ESXi 主机故障导致的虚拟机停机时间。了解 HA 集群如何监控主机健康，检测故障并自动将虚拟机的所有权转移到健康的主机。重点介绍 vSphere 6 新增的“所有路径故障”和“永久设备丢失”处理策略。 * **容错 (Fault Tolerance, FT):** 学习如何通过 FT 完全消除虚拟机在 ESXi 主机故障时的停机风险。FT 通过热复制虚拟机到另一台 ESXi 主机，当原主机故障时，自动接管服务。课程将演示 FT 的配置、运行和测试。 * **VMware Update Manager (VUM):** 了解如何使用 VUM 安全高效地为 ESXi 主机打补丁和更新。学习补丁基线（Patch Baselines）、如何将基线附加到主机或集群、检查补丁合规性以及执行补丁操作。 * **性能优化:** 深入研究 ESXi 主机和虚拟机的性能。了解 vSphere 内核（VMkernel）如何高效利用物理 CPU，如何正确配置虚拟 CPU (vCPU)。掌握 VMkernel 的五种内存管理技术，以及如何启用透明页共享（Transparent Page Sharing）以最大化内存利用率。学习配置存储 I/O 控制（Storage I/O Control），并找出和解决主机及虚拟机的性能瓶颈。 完成本课程后，您将能够更有效地管理 vSphere 6.0 集群，提高系统的可用性和性能。 **附加优势：** 本课程内容100%可下载，方便您根据自己的时间安排进行学习。
VMware vSphere 6.0 is the platform businesses depend on to deploy, manage and run their virtualized Windows and Linux workloads. In this course you will learn how to effectively manage host CPU/Memory resources with DRS clusters, to minimize VM downtime caused by ESXi host failures with HA clusters, to eliminate unplanned VM downtime with Fault Tolerance, to patch and update ESXi hosts with VUM and how to maximize ESXi host and VM performance. Learn DRS & HA Clusters, Fault Tolerance, VMware Update Manager and Performance This course covers five major topics that all vSphere 6 vCenter administrators must know: We start with a thorough presentation of VMware Distributed Resource Scheduling (DRS) clusters. DRS clusters dynamically balance VM CPU and memory demands by automatically VMotion migrating VMs experiencing CPU/Memory resource stress. We also look at Enhanced VMotion Compatibility (EVC) - a feature that lets you safely mix newer and older ESXi hosts in a DRS clusterNext, we will learn how to minimize VM downtime due to unplanned ESXi host failures by implementing High Availability clusters (HA). HA clusters monitor ESXi host health, detect ESXi host failures and re-assign VM ownership from failed ESXi hosts to healthy ESXi host peers. We will also learn about key HA policies like All Paths Down and Permanent Device Loss handling - new to vSphere 6We move on to look at how to completely eliminate unplanned VM downtime (even if an ESXi host fails) through VMware Fault Tolerance (FT). FT hot replicates a running VM to a peer ESXi host. If the ESXi host running the primary copy of a FT protected VM fails, FT automatically places the replicated copy into service. We'll see how to configure, run and test FT protected VMs.Next we will see how to use VMware Update Manager to safely and efficiently patch and update ESXi hosts. We will learn about Patch Baselines (patch sets), how to attach Baselines to an ESXi host or cluster, how to check for patch compliance (all needed patches present on a host) and how to patch ESXi hosts.Finally, we will take a close look at ESXi host and VM performance. We will see what the VMkernel does to efficiently utilize physical CPU and how we can right size vCPU in VMs. We will see the five memory management techniques used by the VMkernel to efficiently manage memory and how to turn on Transparent Page Sharing to maximize memory use. We will see how to configure Storage I/O Control and how to identify and fix host and VM performance bottlenecks. The skills you will acquire in this course will help make you a more effective vSphere 6 administrator.Added Bonus! This course is 100% downloadable. Take it with you and learn on your schedule.
