Hello elearning  , Interesting username choice by the way. Anyway I think we need to clarify, there is no such thing as an 'admin' node in an Isilon cluster, nor are their special interfaces dedicated to management that are out of band like you may be familiar with on other NAS platforms, like the EMC VNX.  All interfaces are available for data access and management access. In general if you have 10Gbe NICs connected to the nodes (like most of our customers do these days), then plugging in one or both of the 1Gbe NICs adds very little value, and increases the complexity of the configuration. I wrote a section in this guide on the subject (see page 9): [URL] Since you are new to the product, hopefully this guide can shed some light on some other topics for you as well.   As to changing client-facing IP addresses of a cluster that's in production of course you can do that, but be advised that it'll likely involve at least a brief disconnection of your clients, and in some cases depending on the application or protocol, may require unmount/remounts.   Hope this helps, Chris Klosterman Advisory SA EMC Enablement Team
