<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">> storage is going to want to do that? The logic behind this escapes me,<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">The reasoning behind this rule is for support. Many Scale support issues - often the toughest ones - are not about a single node, but about the cluster or network as a whole.
So if you have a mix of IBM systems with systems supported by an OEM (this applies to any OEM by the way, not just Lenovo) and a cluster-wide issue, who are you going to call. (Well, in practice you’re going to call IBM and we’ll do our best to help you despite
limits on our knowledge of the OEM systems…). <o:p></o:p></span></p>
