1 SONA – 数据中心的发展之路 林晓

2 传统的数据中心的问题 现有的基础架构 缺乏灵活性 不足的恢复能力 费用高昂 Enterprise Data Center 应用系统及服务
不一致的安全策略 不一致的业务永续/容灾计划 资源利用率不足 运维复杂, 低效 隔离的应用环境 僵化隔离的基础架构 Enterprise Data Center Internet Data Center Public Web Site 100s of Servers with Integrated Storage E-Commerce Application 4-Tier Application App. Server Supply-Chain Management Traditional Voice PBX In-House Developed Apps 2-Tier CRM Application NCR DB Server Data Warehousing Finance, HR, Payroll and EDI Mainframe Systems Tape Backup Multiple 2-Tier ERP Instances Engineering Services NAS Filers Appliances IP Services DNS RADIUS LDAP JBOD Operations Center 应用系统及服务 通讯的应用 计算的基础架构 存储的基础架构 网络基础架构 基础设施 (电力, 冷却, 布线, 及物理安全)

6 今天: 需要部署一个企业的服务 网络管理员确保访问路由指向新的服务器 假设我们需要增加一台服务器到Web服务器群组…
The challenge is one of ‘coordination delays’. This type of simple scale-out of an existing serve often takes enterprises 90-days. New service turn-ups, after the application has been developed, often take 180+ days. VFrame is designed to eliminate these delays and automate the provisioning of services 安全管理员检查安全策略, 增加防火墙的可通过的端口地址 负载均衡管理员把新的服务器加入到服务器群组中 网络管理员连接以太网, 配置 VLAN 及端口的相关设置 系统管理员安装新的服务器 安装 O/S, 补丁及应用系统 存储管理员配置 LUN, 映射至服务器 存储管理员规划磁盘卷及相关资源

7 VFrame 提供企业服务的资源规划(Provisioning)
VFrame 配置端口, VLAN, 及交换策略 VFrame 可控制服务器启动并连接到对应的 LUN/映象 第三方 资源规划的应用 VFrame 获取对应的 LUN 及 WWN 名称 VFrame 获取可用的存储卷及启动的映象文件

8 未来的服务器资源规划的实现 VFrame Provisioning 60+% 服务器利用率 ~30% 服务器数量减少

9 分支架构文件服务器的膨胀 解决方案: 广域应用加速服务

13 Let me end by stressing that Cisco is commited to developing the technologies, solutions and partnerships that will help customers address the data center challenges of today and in the future. Although he Future Data Center vision is an industry vision – it is one that depends on an intelligent network platform. A platform that allows the secure and reliable sharing and virtualization of resources. One that enhances the replication of data and systems between data centers. A platform that optimizes the performance and delivery of applications. A platform that enables the technologies and innovations of 3rd party hardware and software vendors.
