I'm currently looking around at options for Exchange 2003 Mailbox Servers. I'm looking for something which would hold thousands (~5,000) mailboxes. I'm looking for something which utilizes Exchange and VSS like referenced in this article... http://www.windowsitpro.com/Windows/Article/ArticleID/39187/39187.html NetApp, as I understand it, is the most commonly chose option. I'm wondering what experience people have with creating highly available solutions. Are there any solutions out there which are "Exchange Cluster in a box" type things? What products and solutions do people recommend? Thanks in advance, C. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
