Agenda
• 介绍 – 基础架构,四要素,内容和相关文档

• Availability(可靠性)

• Secure Separation(安全隔离)

• Service Assurance(服务保证)

• Management (可管理性)

• Storage in SMT Architecture(SMT架构中的存储系统)

• Summary(总结)
SMT架构与VCE架构的对比
                  Secure Multi-Tenancy       Virtual Computing Environment
底层存储架构     建立在统一存储架构之上的云计算        主要是建立在SAN存储架构上的云计算
                                  Vblock0/Vblock1/Vblock2三种固定配置(Vblock0暂时
配置组合       无固定配置,可根据实际需要选择不同级别的产品 未发布)
                                  Vblock1采用CX4-480(NS-G2为可选);
适用存储类型     NetApp全系列存储产品          Vblock2采用Symmetrix Vmax(NS-G8网关可选);

                                          Vblock1:
                                          Min:CX480/6*SSD/83*FC Disk/21*SATA
                                          Max:CX480/6*SSD/151*FC Disk/27*SATA
                                          估计可用容量38-64TB
                                          Vblock2:
                                          Min:Vmax/9*SSD/124*FC Disk/76*SATA
                                          Max:Vmax/9*SSD/240*FC Disk/110*SATA
配置组合       组合灵活                           估计可用容量96-146TB
           FC SAN:ESX操作系统SAN Boot用;       FC SAN:ESX操作系统SAN Boot用;
           NFS NAS:Datastore存储协议          ISCSI:Datastore存储协议
存储协议       iSCSI(Option)                  NAS(Option):作为VM上应用的补充
数据分级管理     基于SSD的PAM技术实现数据的智能调度           FAST(全自动存储分层)实现LUN级别的存储分层
存储架构扩展     支持纵向、横向线性扩展                    存储网络将存在三种不同类别的存储系统
                                          存储网络可能存在三种不同类别的存储系统,管理将
存储系统可管理性   一套存储OS,维护管理简单                  复杂
           NetApp提供云存储架构下的数据流动性功能-
数据流动性      DataMotion,数据的迁移无需进行服务的中断      由于存在三种存储系统,未提供类似功能
租赁模式支持     是一种充分考虑租赁业务模式的云计算架构            是一种提供主机虚拟化的硬件架构
