IDC称未来四年中国将新增15000家IT企业

Tuesday, December 8, 2009 12:56

据研究机构IDC公布最新数据显示,中国软件外包业近十年发展迅猛,截止去年底,各类外包企业已达3300家,合同执行额46.9亿美元。预计未来四年,中国还将迎来新一轮发展高峰,至2013年,中国将新增15000家IT企业。   IDC研究报告预测,金融危机带来全球资源调整,中国充裕的人力资源及庞大内需市场成为众多跨国企业的追逐焦点。未来五年内,中国离岸软件外包市场将以年均35.5%的速率增长,对欧美市场的年增长率可达44.7%,并将在2012年产生近89.5亿美元的总收入。   出于对成本的考虑,中国二线城市逐渐受国际外包商的青睐。无锡、苏州等二线城市,以及南昌、西安、成都等中西部城市也成为国际外包上考虑的重点。   不过,对于中国软件外包产业来说,还存在高层次人才缺乏、核心竞争力不高等问题,但随着外包产业成熟度提升,中国庞大的中低层从业人员将是其发展的最大优势。目前,中国拥有476万的IT从业人员,预计到2013年,这个数字将达642万。 This article is from http://news.chinaunix.net

Windows server 2008 R2 Hyper-v

Thursday, December 3, 2009 10:27

继一个月前完成RTM后,微软今天终于放出了Hyper-V Server 2008 R2最终正式版的公开下载。这是一款基于Hyper-Visor的独立虚拟化产品,免费提供。 与之前的Hyper-V Server 2008相比,新版本增加了大量新特性,特别是动态迁移(Live Migration)、故障转移集群(Failover Cluster)、新版服务器配置工具等等,同时物理系统处理器、内存支持从四路/24核心、32GB扩展到了八路/64核心、1TB,另外最多可运行的虚拟系统也从192个翻番到了384个。 微软表示,Hyper-V Server 2008 R2可以让企业组织把大量分散工作集中到一台物理服务器上,以可靠、优化的虚拟化方案提高服务器利用率、降低成本。 系统需求: - 操作系统:Hyper-V Server 2008 - 处理器技术:64位、Intel VT或AMD-V、硬件DEP、Intel XD bit或AMD Nx bit - 处理器频率:最低1.4GHz,推荐2.0GHz或更快 - 内存容量:最少1GB,推荐2GB或更多 - 硬盘空间:最少8GB,推荐20GB或更多 支持虚拟操作系统(括号内为可分配物理处理器数量): - Windows Server 2008 R2 (1/2/4) - Windows Server 2008 x64/x86 (1/2/4) - Windows Server 2003 R2 x64/x86 (1/2) - Windows Server 2003 x64/x86 (1/2) - Windows Server 2000 (1) - ...

Windows server 2008 Hyper-v

Thursday, December 3, 2009 10:25

Hyper-V是一个只有几百KB的小程序,Hyper-V介于物理硬件和虚拟机之间,代码非常少,不含任何第三方的驱动,非常的精简,这种构架使得虚拟机和硬件之间只通过很薄的一层进行连接,不像Virtual Server那样虚拟机和硬件之间需要经过多层的转换,因而虚拟机执行效率非常高,可以更加充分的利用硬件资源,使虚拟机系统性能非常的接近真实的操作系统性能。 正式发布的Hyper-V基于32位和64位系统,不过由于32位系统的内存寻址空间只有4GB,所以对于虚拟化应用没有太大的现实意义。Hyper-V对于硬件的支持大大提升,支持4颗虚拟处理器,支持64GB内存。 Hyper-V提供了对多个操作系统的支持如Windows Server 2003 SP2、Novell SUSE Linux Enterprise Server 10 SP1、Windows Vista SP1 (x86)和Windows XP SP3 (x86)等。Hyper-V也支持远程管理功能,基于Vista的远程管理补丁目前也已经发布,用户可以在Vista客户端打开Hyper-V控制台远程对服务器进行操作。
