Hi, We are currently using Mellanox NICs which support RDMA

Can we run all the normal VMware services (vMotion, Management, etc) on these NICs? I ask because in https://support.purestorage.com/?title=Solutions/VMware_Platform_Guide/How-To%27s_for_VMware_Solutions/NVMe_over_Fabrics/How_To:_Setup_NVMe-RDMA_with_VMware|this KB it says these NICs should not be used. The KB states configuring an RNIC with multiple services is not recommended by VMware. Is there a source?

vmware

    That was traditionally the same case for iSCSI vmks as well, that you wouldn't want to set other services on those vmks. I'm not sure the specific vmware documentation on it, might be from their storage hub best practices. I know I've read it before, just can't remember where.
