<p class="MsoNormal">I'm definitely going to ask for that option. I think in this situation DAS is the way to go. The only issue is that it's going to be the odd duck out. They're going to have to design a RAID array configuration for the chassis. If we want
chassis redundancy, it means duplicating the disk array configuration. <o:p></o:p></p>

NAS/SAN? I'm wondering, if we bite the bullet and use DAS, we might eliminate some of the complexity and have (almost) guaranteed performance.<br>

I've been asked to produce a short report, comparing the resources and support options of Cisco UCS vs Spec's based solution, i.e. an existing infrastructure.<br>
<br>
There is a lot of information out there that I will be using, but I'm also interested in hearing from others who have produced a similar report.
<br>
<br>
Also, if others are willing to share support issues that have cropped up which you had difficulty dealing with, that would be great too. I'd like to be able to include some real world examples.<br>
