Storage
信息来源：http://searchservervirtualization.techtarget.com 据报道，明年早些时候 VMware 及其存储领域的合作伙伴将联合发布新的和存储相关的 API，目前命名为 VMware Aware Storage APIs (VASA)，其功能是加强对物理存储基础架构的可视化，可以通过 vCenter 和 CapacityIQ 工具获得对物理存储阵列的一些细节信息，如 RAID 信息，磁盘数量等等。 有分析人士称，通过 VASA VMware 将要实现对存储的可视化，下一步恐怕就是要实现 vCenter 对存储日常配置的接管了。 VASA vs VAAI 这里对 VASA 和已经存在的 vStorage APIs for Array Integration (VAAI) 两个术语做个总结。 VAAI 是存储产品的一个功能，如果存储支持并开启了这个功能，ESX(i) 主机会自动识别并使用，VAAI 可以实现将原来的 ESX(i) 主机部分 CPU 负载迁移到存储设备上，提高整个虚拟环境的效率。如在大规模的 VDI 部署（可以提高虚机启动速度和桌面负载的性能）和大型数据中心服务器虚拟化部署（改善虚机部署性能，thin-provisioned 时）等等。 VASA 则应该只是实现加强虚拟化层对存储物理层的可视化，将原本的存储厂商的管理工具的部分工具合并到 VMware 的管理工具中。
As I have learned from New Concept English III that predicting the future is notoriously difficulty, especially in our modern quick developing world. Ok, but here comes Henry Newman, he self-clamed some successful predicts of the Data Storage industry development in 2009. And here is his storage predictions for 2010 and the year beyond Storage [...]

AoE (ATA Over Ethernet) is a very simple and lightweight protocol which does not rely on network layers above Ethernet, this makes AoE potentially faster than iSCSI, with less load on the host to handle the additional protocols, it also means that AoE is not routable outside a LAN. AoE is intended for SANs only. [...]
Because blade servers may have a limited number of network adapters, it will likely be necessary to use VLANs to separate traffic for the service console, VMotion, IP storage, and various groups of VMs. VMware best practices recommend that the service console and VMotion have their own networks for security reasons. If you dedicate physical [...]
