虚拟化架构
当前数据中心状态 Gartner – 超过70%的全球1000企业都将在今后5年内对数据中心的设备进行更新与扩展 美国拥有最多的大型数据中心 IDC 评估了 7,000 个企业数据中心 (25k sq. ft.) 大部分都在刀片出现之前设计(7年以上) 按 35 - 70 W/sqft 设计(当前需求150-200 W/sqft - Gartner) 数据中心挑战(IDC) 电源/散热 可用性/冗余/灾备 空间受限 * Tier Level (Weighted Average) Tier 1 Tier 2 Tier 3 Tier 4 Unsure Source: Key Findings from Datacenter Dynamics shows in 8 cities in 2008 Source: Marsan, Carolyn Duffy, Data center power: the cost reality, NetworkWorld, Feb. 18th, 2008 Power Usage in the Datacenter 9.43 19.75 39.99 16.02 14.82 Aging data centers: Last year, The Gartner Group said that any data center built prior to 2000 was likely to be obsolete Increasing power & cooling consumption In 2006, U.S. data centers consumed 61 billion kilowatt-hours of electricity. This is equal to about 1.5% of total U.S. electricity consumption. By 2011, it is estimated that data centers will consume over 100 billion kWh, representing a $7.4 billion annual electricity cost. In 2007, Mellon Financial Corp. announced that it would spend $70 million to expand the power & cooling infrastructure at a Pittsburgh-area data center that was less than a year old. A study done in February and March of this year by IntelliClear for HP showed that the average power consumption per rack in the U.S. is now over 11 kW. Increasing cost of power Last year, the DOE said the average retail price of electricity increased by 9.1%. The largest jump in 25 years.
