Network Speed from Software iSCSI to the SPs

[CSllama]

Should the network speed be the same from the NICs on the ESXi hosts through the switch to the storage? I currently have 1GB NICs on the ESXi hosts going to the Nexus switches then 10GB from the Nexus switches to the VNX SPs.

Thanks in advance.

Welcome to the Community - I am not sure I understand your question - the network bandwidth between the ESXi host and the NExus switch will be 1 GB the bandwidth between the NExus switch and your SAN will be 10 GB - in an ideal world the most that your iSCSI traffic will ever occuoy is 1 GB

It does not need to be equal end to end.  However, if its not, obviously you will be limited by the performance of the slowest link.

Thanks, this was what I was looking for - I knew it was limited to the slowest link but was curious about the entire speed from end to end, if it needed to be the same.
