ESXi Networking in Metro Configuration


Forum|alt.badge.img+1

Hi all,

 

I'm in the process of creating two new Nutanix clusters and configuring Metro availability for replication.

 

Our network uses a spine-leaf architecture, with 10 nodes on each site. Latency for site-to-site connectivity is under 5ms

 

VLANs can be stretched between sites for seamless failover of all VM workloads. Additionally, I plan to use network segmentation to isolate storage/RF traffic for each cluster.

 

I’m aware the all ESXi hosts need to part of the same ESXi Cluster for a supported Metro Availability configuration.

I would like some advice on whether the ESXi hosts should be on the same stretched Layer 2 network or if they can be independent. For example, having ESXi hosts on site A use 192.168.5.0/24 and ESXi hosts on site B use 172.16.2.0/24.

Are there any downsides to this approach? It feels more straightforward not to stretch the VLANs for host management networks.

 

Has anyone else managed something similar? Any insights or best practices would be greatly appreciated.

 

Thanks in advance

They can be on different vlan’s/subnets. Hereby a blog post i created some years ago: https://next.nutanix.com/community-blog-154/step-by-step-guide-to-deploying-nutanix-metro-availability-40808
