1. Re: vSAN Networking Design - 10GbE Base-T
yezdi Nov 15, 2019 6:11 AM (in response to NhutVu)1 person found this helpfulThe requirement is 10GB end-to-end (Between all the hosts in the vSAN cluster) connectivity, that includes Physical NIC, ToR switches etc. If its available then all flash vSAN should be fine. We've multiple all flash vSAN environments with 10Gig network.

NhutVu Jul 17, 2019 2:26 AM (in response to yezdi)Yes, as we also understood that the connection just need to be 10GbE, does not need to be a specific 10GbE like Fiber, DAC or Base-T.
What our team worrying is the latency of network. As the 10Gb BASE-T network latency is usually a little bit higher than 10GbE Fiber or 10GbE DAC connection.

yezdi Jul 18, 2019 1:31 AM (in response to NhutVu)1 person found this helpfulOur all flash vSAN environments are on 10GB Base-T network. I couldn't find best practice articles on vSAN Network design which compares 10GbE Fiber cs 10GbE Base-T. The vSAN network design guide doesnt say to not to use copper. But definitely you can reach out to VMware and ask their recommendation.
