VMWAREVSPHERE产品简介.ppt

* Key Points: Server sprawl of underutilized x86 servers creates significant problems for IT departments today (cost, management challenges, etc.) VMware server virtualization allows you to control server sprawl: Consolidate existing servers onto fewer machines using virtual machines to get more value out of existing resources and avoid costly forced migrations of legacy applications to new platforms Contain future server growth by putting new applications in virtual machines rather than buying new servers Script: One key challenge facing IT today is managing the growing sprawl of servers, particularly x86 servers. VMware virtual infrastructure provides you the ability to take control of server growth. For one, it allows you to consolidate existing applications onto fewer servers. Because you can run multiple virtual machines with different OS’s and different applications simultaneously, you can combine heterogeneous servers into a single server. Consolidation allows you to support old applications on new hardware and to retire that old hardware from the datacenter. You can also you virtual infrastructure to contain future server growth. With virtual infrastructure you can provision new virtual machines without needing to provision new servers—the new virtual machines can utilize unused capacity in your existing environment. You can plan your purchases of servers to add overall capacity rather than reactively deploying new server hardware for each request. Result: easier to manage, reduced datacenter costs, reduced procurement and deployment costs * * 服务器整合的效果 35%-75% TCO 节省 通过将整合多个物理服务器到一个物理服务器降低40％软件硬件成本 整合比：生产环境10-15 : 1 ，开发测试环境15-20 : 1 每个服务器的平均利用率从7％提高到60%-80% 降低70-80%运营成本， 包括数据中心空间、机柜、网线，耗电量，冷气空调和人力成本 提高运营效率 部署时间从小时级到分钟级， 服务器重建和应用加载时间从 20-40 hrs =15-30 min， 每年节省10,000 人/小时（300台服务器） 以前硬件维护需要以前的数天/周的变更管理准备和1 - 3小时维护窗口，现在可以进行零宕机硬件维护和升级 提高服务水平 帮助您的企业建立业务和IT资源之间的关系，使IT和业务优先级对应 将所有服务器作为大的资源统一进行管理，并按需自动低动态资源调配 无中断的按需扩容 旧硬件和操作系统的投资保护 不再担心旧系统的兼容性，维护和升级等一系列问
