VMware ESXi 8.0 是一款非常优秀的电脑虚拟化服务器软件。该软件主要针对虚拟机、最大限度降低配置要求和简化部署而设计，我们只需要花费几分钟就可以完成从安装到运行虚拟机的全过程，尤其是在下载并安装预配置虚拟设备的时候。针对vSAN环境的增强型vSphere Lifecycle Manager硬件兼容性预检查：ESXi 7.0 Update 1添加了vSphere Lifecycle Manager硬件兼容性预检查。在某些更改事件（如修改集群所需映像或在vSAN环境中添加新的ESXi主机）之后，预检查会自动触发。此外，硬件兼容性框架还会按预定义的时间间隔自动轮询硬件兼容性列表数据库，以便在必要时触发预检查。
Enhanced vSphere Lifecycle Manager hardware compatibility pre-checks for vSAN environments: ESXi 7.0 Update 1 adds vSphere Lifecycle Manager hardware compatibility pre-checks. The pre-checks automatically trigger after certain change events such as modification of the cluster desired image or addition of a new ESXi host in vSAN environments. Also, the hardware compatibility framework automatically polls the Hardware Compatibility List database at predefined intervals for changes that trigger pre-checks as necessary.
Increased number of vSphere Lifecycle Manager concurrent operations on clusters: With ESXi 7.0 Update 1, if you initiate remediation at a data center level, the number of clusters on which you can run remediation in parallel, increases from 15 to 64 clusters.
vSphere Lifecycle Manager support for coordinated updates between availability zones: With ESXi 7.0 Update 1, to prevent overlapping operations, vSphere Lifecycle Manager updates fault domains in vSAN clusters in a sequence. ESXi hosts within each fault domain are still updated in a rolling fashion. For vSAN stretched clusters, the first fault domain is always the preferred site.
Extended list of supported Red Hat Enterprise Linux and Ubuntu versions for the VMware vSphere Update Manager Download Service (UMDS): ESXi 7.0 Update 1 adds new Red Hat Enterprise Linux and Ubuntu versions that UMDS supports. For the complete list of supported versions, see Supported Linux-Based Operating Systems for Installing UMDS.
Improved control of VMware Tools time synchronization: With ESXi 7.0 Update 1, you can select a VMware Tools time synchronization mode from the vSphere Client instead of using the command prompt. When you navigate to VM Options > VMware Tools > Synchronize Time with Host, you can select Synchronize at startup and resume (recommended), Synchronize time periodically, or, if no option is selected, you can prevent synchronization.
Increased Support for Multi-Processor Fault Tolerance (SMP-FT) maximums: With ESXi 7.0 Update 1, you can configure more SMP-FT VMs, and more total SMP-FT vCPUs in an ESXi host, or a cluster, depending on your workloads and capacity planning.
Virtual hardware version 18: ESXi Update 7.0 Update 1 introduces virtual hardware version 18 to enable support for virtual machines with higher resource maximums, and:Secure Encrypted Virtualization - Encrypted State (SEV-ES)
Virtual remote direct memory access (vRDMA) native endpoints
EVC Graphics Mode (vSGA).Increased resource maximums for virtual machines and performance enhancements:With ESXi 7.0 Update 1, you can create virtual machines with three times more virtual CPUs and four times more memory to enable applications with larger memory and CPU footprint to scale in an almost linear fashion, comparable with bare metal. Virtual machine resource maximums are up to 768 vCPUs from 256 vCPUs, and to 24 TB of virtual RAM from 6 TB. Still, not over-committing memory remains a best practice. Only virtual machines with hardware version 18 and operating systems supporting such large configurations can be set up with these resource maximums.
Performance enhancements in ESXi that support the larger scale of virtual machines include widening of the physical address, address space optimizations, better NUMA awareness for guest virtual machines, and more scalable synchronization techniques. vSphere vMotion is also optimized to work with the larger virtual machine configurations. 新增功能在以下服务器中，ESXi 7.0 Update 1 支持 vSphere 快速引导：HPE ProLiant BL460c Gen9HPE ProLiant DL325 Gen10 PlusHPE ProLiant DL360 Gen9HPE ProLiant DL385 Gen10 PlusHPE ProLiant XL225n Gen10 PlusHPE Synergy 480 Gen9增强了适用于 vSAN 环境的 vSphere Lifecycle Manager 硬件兼容性预检查：ESXi 7.0 Update 1 增加了 vSphere Lifecycle Manager 硬件兼容性预检查。预检查可在某些更改事件（例如，修改集群所需映像或在 vSAN 环境中添加新的 ESXi 主机）后自动触发。此外，硬件兼容性框架会根据需要按预定义时间间隔自动轮询硬件兼容性列表数据库以查找触发预检查的更改。增加了集群上 vSphere Lifecycle Manager 并发操作的数量：在 ESXi 7.0 Update 1 中，如果在数据中心级别启动修复，可以并行运行修复的集群数从 15 个增加到了 64 个。vSphere Lifecycle Manager 支持在可用区之间协调更新：在 ESXi 7.0 Update 1 中，为了防止操作重叠，vSphere Lifecycle Manager 将按顺序更新 vSAN 集群中的故障域。每个故障域中的 ESXi 主机仍以滚动方式进行更新。对于 vSAN 延伸集群，第一个故障域始终是首选站点。扩展了 VMware vSphere Update Manager Download Service (UMDS) 支持的 Red Hat Enterprise Linux 和 Ubuntu 版本的列表：ESXi 7.0 Update 1 添加了 UMDS 支持的全新 Red Hat Enterprise Linux 和 Ubuntu 版本。有关支持版本的完整列表，请参见支持安装 UMDS 的基于 Linux 的操作系统。改进了对 VMware Tools 时间同步的控制：在 ESXi 7.0 Update 1 中，可以从 vSphere Client 中选择 VMware Tools 时间同步模式，而不是使用命令提示符。导航到虚拟机选项 > VMware Tools > 与主机同步时间时，可以选择在启动和恢复时同步 (建议) 或定期同步时间，或者，如果未选择任何选项，可以禁止同步。增加了对 Multi-Processor Fault Tolerance (SMP-FT) 最高配置的支持：在 ESXi 7.0 Update 1 中，可以根据自己的工作负载和容量规划在 ESXi 主机或集群中配置更多 SMP-FT 虚拟机和更多 SMP-FT vCPU（总数）。 虚拟硬件版本 18：ESXi Update 7.0 Update 1 引入了虚拟硬件版本 18，可支持资源最高配置较高的虚拟机，并支持：Secure Encrypted Virtualization - Encrypted State (SEV-ES)虚拟远程直接内存访问 (vRDMA) 原生端点EVC 图形模式 (vSGA)。增加了资源最高配置以增强虚拟机并提高性能：在 ESXi 7.0 Update 1 中，可以创建虚拟 CPU 多三倍、内存多四倍的虚拟机，以使比裸机具有更大内存和 CPU 占用空间的应用程序能够以近乎线性的方式进行扩展。虚拟机资源最高配置如下所示：vCPU 从 256 个最多增加到 768 个，虚拟 RAM 从 6 TB 最多增加到 24 TB。但最佳做法仍是不要超额分配内存。只有硬件版本为 18 且操作系统支持此类大型配置的虚拟机才能设置这些资源最高配置。ESXi 中的性能增强支持更大规模的虚拟机，包括物理地址扩大、地址空间优化、改进对客户机虚拟机的 NUMA 感知以及更具可扩展性的同步技术。vSphere vMotion 也进行了优化，可与较高的虚拟机配置配合使用。具有 AMD 处理器的 ESXi 主机可以支持 vCPU 多两倍 (256)、RAM 多达 8 TB 的虚拟机。对于内存模式和应用直接模式，持久性内存 (PMEM) 支持翻倍，从 6 TB 增加到 12 TB。ESXi hosts with AMD processors can support virtual machines with twice more vCPUs, 256, and up to 8 TB of RAM.Persistent memory (PMEM) support is up twofold to 12 TB from 6 TB for both Memory Mode and App Direct Mode.System requirements: CPU: x86_64 compatible
