51. During a vSAN design workshop, a customer expressed a requirement to decommission an existing enterprise NAS device that provides iSCSI services for a clustered application.

Based on the current state analysis, the following information was noted:
• Current utilization is 500 LUNs.
• All clustered workloads are configured for Multiple Connections per Session.
• LUN sizes range between 10 TB to 30 TB.

What should the architect state regarding the requirements?

• A. All requirements can be satisfied without any change.
• B. Only single connection per session is supported.
• C. The number of LUNs require additional licensing.
• D. It is a best practice to maintain a LUN size of 8 TB.

Explaination:

Based on the VMware knowledge base article https://kb.vmware.com/s/article/57344, the correct answer would be:

B. “Only single connection per session is supported.”

In the context of a vSAN design, this response directly addresses the customer’s requirement related to the configuration of clustered workloads with Multiple Connections per Session. According to VMware’s guidelines for vSAN, only single connection per session is supported for iSCSI. This limitation would be a critical point to consider in the design phase, especially when decommissioning an existing enterprise NAS device that currently supports multiple connections per session for clustered applications.

51. 在一次vSAN设计研讨会上，一位客户提出了一个要求，即要淘汰一台现有的提供iSCSI服务的企业级NAS设备，该设备用于一个集群应用。

基于当前状态分析，记录了以下信息：

• 当前使用了500个LUN。
• 所有集群工作负载都配置为每个会话多个连接。
• LUN大小在10 TB到30 TB之间。

架构师应该如何回应这些要求？

• A. 所有要求都可以在不做任何改变的情况下得到满足。
• B. 只支持每个会话单个连接。
• C. LUN数量需要额外的许可证。
• D. 维持8 TB的LUN大小是最佳实践。

解释：

根据VMware知识库文章https://kb.vmware.com/s/article/57344，正确答案是：

B. “只支持每个会话单个连接。”

在vSAN设计的背景下，这个回答直接解决了客户关于配置集群工作负载以支持每个会话多个连接的需求。根据VMware对vSAN的指南，iSCSI只支持每个会话单个连接。在设计阶段，这个限制是一个关键点，尤其是在淘汰当前支持集群应用的每个会话多个连接的现有企业级NAS设备时。
