Deduplication removes redundant data blocks, whereas compression removes additional redundant data within each data block. These techniques work together to reduce the amount of space required to store the data. applies deduplication and then compression as it moves data from the cache tier to the capacity tier.

2024年9月5日 · 本文介绍了如何安全地从 vSAN 环境中移除硬盘，包括检查磁盘健康状态、使用命令行工具排查故障以及处理常见的硬盘移除失败问题。 针对不同场景，提供了详细的操作步骤和故障解决方案，如启用去重模式或处理硬盘通信丢失问题。

VMware vSAN storage clusters (previously known as vSAN MaxTM) is a new deployment option within vSAN that provides highly flexible and scalable disaggregated storage for vSphere clusters, powered by the vSAN Express Storage ArchitectureTM, or ESA.

在安装部署 VSAN 前，先检查一下当前环境是否满足要求。 1、标准部署，最少不低于3台esxi主机； 2、每台 esxi 主机至少 6GB内存. 3、VMware vCenter Server 至少一个容量层设备，对于给VSAN数据存储提供存储的主机而言，混合配置至少. 一块磁盘，全闪存配置至少一块 ...

Use vSAN Direct to enable stateful services to access raw, non-vSAN local storage through a direct path. You can claim host-local devices for vSAN Direct, and use vSAN to manage and monitor those devices.

You can use the vSAN Sizer tool https://vsansizer.esp.vmware.com/ to assist with capacity requirements, and to determine how vSAN can your meet performance requirements.

本文详细介绍VMware vSphere 6.7环境下vSAN的配置过程，包括分布式交换机创建、主机添加、网络配置、集群建立及HA与DRS设置等关键步骤。 也可以不勾选创建默认端口组，随后手动创建。 我这里手动创建，见如下： 完成之后，验证：这时对应主机上出现vsan刚才新增的vmkernel适配器. 因分布上交换机上联端口环境中均采用了动态链路聚合，这里使用LACP，将2张上链网卡放在一个LACP标签下（注意：需与网络人员确认是否上层做了端口链路聚合，且上联端口是否 …

2024年11月26日 · vSAN 是 VMware 推出的软件定义存储方案，通过聚合 vSphere 集群中 X86 服务器的本地磁盘并形成一个抽象的存储池以供虚拟机/容器等负载使用。 VMware vSAN 最早于 2014 年发布，至今已过去 10 年时间，每一年里都发生了许许多多的变化，有的可能是版本功能的增强，有的可能是新功能新特性的增加。

What is vSAN Direct Configuration, and how does it relate to the vSAN DPp? 26 For eligible applications, what are the key considerations when determining whether to use a cluster providing storage using “vSAN SNA” versus “vSAN Direct Configuration?” 26

VMware® vSANTM is a hyper-converged, software-defined storage (SDS) platform that is fully integrated with VMware vSphere®. vSAN aggregates locally attached disks of hosts that are members of a vSphere cluster to create a distributed shared storage solution. vSAN activates the rapid provisioning of storage within VMware vCenterTM as part of virt...
