50. An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the data. Both vSAN clusters are managed by the same vCenter server.
What should the administrator configure?
- A. NFS volumes on vSAN
- B. iSCSI targets on vSAN
- C. HCI Mesh on vSAN
- D. vVOLs on vSAN
Explaination:
The administrator should configure C. HCI Mesh on vSAN.
HCI Mesh is a technology provided by VMware for vSAN clusters, which allows one vSAN cluster to share its storage resources with another vSAN cluster. This is particularly useful in scenarios where you want to preserve storage policy-based management (SPBM) end-to-end, as is the case here.
Here’s a brief overview of why HCI Mesh is the appropriate choice:
- NFS volumes on vSAN: NFS is a network file system protocol, but using it in this context would not preserve the SPBM capabilities of vSAN.
- iSCSI targets on vSAN: While iSCSI allows block-level storage sharing over a network, it doesn’t fully integrate with vSAN’s native SPBM features in the same seamless way as HCI Mesh.
- HCI Mesh on vSAN: This option allows a vSAN cluster to share its storage with another vSAN cluster in a way that fully supports SPBM. It’s specifically designed for this purpose within vSAN environments, making it the ideal choice for scenarios where SPBM management is a priority.
- vVOLs on vSAN: Virtual Volumes (vVOLs) are an integration and management framework, but they don’t inherently provide a method for sharing storage across vSAN clusters while preserving SPBM like HCI Mesh does.
Given that both vSAN clusters are managed by the same vCenter server and there’s a need to maintain SPBM from the source vSAN cluster, HCI Mesh is the most suitable option.
50. 一名管理员负责将存储从一个vSAN集群共享到另一个vSAN集群。必须从端到端保留SPBM（存储策略基础管理），并且策略必须由存储数据的源vSAN集群应用。这两个vSAN集群都由同一个vCenter服务器管理。 管理员应该配置什么？
- A. vSAN上的NFS卷
- B. vSAN上的iSCSI目标
- C. vSAN上的HCI Mesh
- D. vSAN上的vVOLs
解释：
管理员应配置C. vSAN上的HCI Mesh。
HCI Mesh是VMware为vSAN集群提供的一项技术，它允许一个vSAN集群与另一个vSAN集群共享其存储资源。这在你想要从端到端保留存储策略基础管理（SPBM）的场景中特别有用，正如这里的情况。
以下是为什么HCI Mesh是合适选择的简要概述：
vSAN上的NFS卷：NFS是一种网络文件系统协议，但在这种情况下使用它不会保留vSAN的SPBM功能。
vSAN上的iSCSI目标：虽然iSCSI允许通过网络共享块级存储，但它并没有以与HCI Mesh一样无缝的方式完全集成vSAN的原生SPBM功能。
vSAN上的HCI Mesh：这个选项允许vSAN集群以完全支持SPBM的方式与另一个vSAN集群共享其存储。它专为vSAN环境中的此类场景设计，使其成为在SPBM管理是优先考虑的情况下的理想选择。
vSAN上的vVOLs：虚拟卷（vVOLs）是一个集成和管理框架，但它们本身不提供一种在保留SPBM的同时跨vSAN集群共享存储的方法，如HCI Mesh所做的那样。
考虑到这两个vSAN集群都由同一个vCenter服务器管理，并且需要从源vSAN集群保持SPBM，HCI Mesh是最合适的选项。
