戴尔机架式服务器的优缺点

戴尔已经淡化了服务器市场，现在一个城市的戴尔服务器服务站很少，有的就一个，还有的就没有，他们只管买，售后麻烦的要死，像深圳这样的城市都没一个服务站，除了代理戴尔的卖家外，其技术工程师还要从厦门那叫过来，要是出了服务期，呵呵花销吓人啊，由此可见其售后和市场形势多不好
价格是个优势，可维护等问题也要考虑，不要贪便宜，IBM的服务器还是首选，什么叫专业，个人建议

通过Fan Speed Offset(风扇转速抵消)的设置可以将风扇转速提升，以提供更多的散热。低风扇转速抵消（Low Fan Speed Offset ）设置可以使机器稳定在适度的风扇转速中（接近50%），高风扇转速抵消 (High Fan Speed Offset） 设置可以使机器稳定在全速运转的状态（接近90%-100%）。
12G/13G可通过BIOS设置FAN Speed Offset：
BIOS-> iDrac settings->Therma->Fan Speed Offset
