Physical switches and vSAN

ScottSzcz — Thu, 31 Mar 2022 15:25:44 GMT

Is MLAG absolutely necessary for all flash vSAN? We are working on a virtualization project, we have quotes ready and are sure about everything except for the switching with vsan at the moment. Long story short we're doing a small deployment, 3-nodes, under 10 VMs, and the switches we have are USW-Pro-Aggregation switches from Ubiquiti. These switches do not support MLAG. Can we achieve an all flash vSAN and manage all the traffic through two switches without MLAG?

We almost never use MLAG. Better get faster NICs and switches.

MLAG is not a requirement. You need redundant networking gear and when you create the ISL just be sure that it have enough bandwidth and redundancy. So a LAG with 2x10 or 2x25 would be fine between your 2 switches.

When speaking of MLAG i must think about HPE(Aruba) where other Vendors have things like VLTi and so on.

Thank you . I figured it was a bit overkill and wanted to make sure I wasn't going to hit a wall with requirements.
