摘要:09年,IBM宣布推出了云计算领域最新存储战略计划,这个被称为“企业级智能云存储”的应用是一种基于私有云的存储和归档技术,旨在为企业客户提供应用程序方面的支持。这种云存储主要是通过存储虚拟化来实现的。这跟EMC等厂商提供给客户现有的低成本云存储应用环境,对二级或三级数据副本或在开发利用和测试环境中存储应用是有区别的。IBM的云存储是基于IBM存储虚拟化配合了各种存储设备来实现的一体化解决方案。IBM云计算解决方案是IBM云计算中心经过多年的探索和实践开发出来的先进的基础架构管理平台。该方案结合了业界最新技术,充分体现云计算理念,已在IBM内部成功运行多年,并在全球范围内有众多客户案例。该解决方 阅读全文
