&lt;OL&gt;
&lt;LI&gt;Se o hardware não suporta plataforma 64 bits&lt;/LI&gt;
&lt;LI&gt;Se o software utilizado não suporta plataforma 64 bits&lt;/LI&gt;&lt;/OL&gt;
&lt;P&gt;Segue o link de um artigo bem interessante sobre as “infinitas” vantagens do SQL Server 2005 (64 bits) x SQL Server 2005 (32 bits).&lt;/P&gt;
&lt;P&gt;&lt;A href="http://download.microsoft.com/download/a/4/7/a47b7b0e-976d-4f49-b15d-f02ade638ebe/Adv64BitEnv.doc" mce_href="http://download.microsoft.com/download/a/4/7/a47b7b0e-976d-4f49-b15d-f02ade638ebe/Adv64BitEnv.doc"&gt;http://download.microsoft.com/download/a/4/7/a47b7b0e-976d-4f49-b15d-f02ade638ebe/Adv64BitEnv.doc&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;Na introdução deste artigo temos a seguinte frase: “Microsoft SQL Serverä 2005 Standard and Enterprise Editions (64-bit) offer dramatic improvements in memory availability and parallel processing performance when compared to SQL Server software running in a 32-bit environment”&lt;/P&gt;
&lt;P&gt;Além disso, se olharmos os benchmarks de SQL Server, só aparecem servidores 64 bits, conforme link: &lt;A href="http://www.tpc.org/tpce/results/tpce_results.asp?orderby=hardware" mce_href="http://www.tpc.org/tpce/results/tpce_results.asp?orderby=hardware"&gt;http://www.tpc.org/tpce/results/tpce_results.asp?orderby=hardware&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;Outro ponto que é super importante é a facilidade de migração do ambiente 32 bits para 64 bits conforme página 22 do artigo: “The migration of data from SQL Server 2000 (32-bit and 64-bit) and SQL Server&amp;nbsp; 2005 (32-bit) to SQL Server 2005 (64-bit) is a straightforward task, as both share the same on-disk data and log file format. The mechanisms available include using detach and attach or backup and restore.”&lt;BR&gt;&lt;/P&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3142880" width="1" height="1"&gt;</description><category domain="http://blogs.technet.com/mhunecke/archive/tags/64bits/default.aspx">64bits</category><category domain="http://blogs.technet.com/mhunecke/archive/tags/SQL/default.aspx">SQL</category><category domain="http://blogs.technet.com/mhunecke/archive/tags/TPC/default.aspx">TPC</category></item></channel></rss>
