Hi Guys - a customer has pointed out some confusing information regarding FA, ESXi ISCSI and port binding
According to https://core.vmware.com/resource/best-practices-running-vmware-vsphere-iscsi#sec7262-sub12 port binding is unsupported if the FA has iscsi-interfaces in 2 subnets. On https://support.purestorage.com/Solutions/VMware_Platform_Guide/User_Guides_for_VMware_Solutions/FlashArray_VMware_Best_Practices_User_Guide/VMware_and_iSCSI_FAQs#NIC_Teaming_vs_Port_Binding.2C_which_should_I_use.3F|https://support.purestorage.com/Solutions/VMware_Platform_Guide/User_Guides_for_VMware_S[…]ay_VMware_Best_Practices_User_Guide/VMware_and_iSCSI_FAQs it is stated "So which should you use? The answer here is clear, port binding whenever possible. This is not only recommended as a best practice with Pure Storage but by VMware as well."
- So thinking about this as well, this is a better KB to follow. https://kb.vmware.com/s/article/2038869 in this case i wouldnt call it unsupported, but its not recommended and it highlights the reasons why. ISCSI Port binding should only be used wen the source and destination are in a single broadcast domain
