增强的高可用性 – 虚拟机故障监控 整合的备份 (VCB) 增强功能 30 VCB 现可支持通过 iSCSI、NAS 连接到虚拟机或本地连接的存储器（已在 3.0.2 中发布，但很多人并不了解）。这是一种节约成本的元素，使 VCB 在 SMB 空间更具吸引力。 能够在虚拟机中运行 VCB，且不需要在 Windows 上运行专用的备份代理服务器。这是一种节约成本的元素，使 VCB 在 SMB 空间更具吸引力，也使得如 VMotion 和 DRS 这类 VI 功能可以最大程度地利用现有资源。 VMware Converter 用来恢复 VCB 映像（与 3.0.1 一起发布，但很多人并不了解），它能够将虚拟机的 VCB 影响恢复为正在运行的虚拟机。这是将虚拟机从磁带中恢复并将其放回到 VI 的简单 1 步式图形方式。 图形用户界面与主要合作伙伴的全面集成 – 使用 NetBackup 6.5 示例（8 月份刚刚发布），该示例使 VCB 无需脚本编制即可运行，并可通过 NetBackup 图形用户界面来进行全面配置。 * VMware Fault Tolerance is a component of VMware vSphere? that ensures continuous availability for virtual machines against hardware failures. VMware FT creates virtual machine “pairs” that run in lock step - essentially mirroring the execution state of a VM. To the external world they appear as one instance (one IP address, one application) – but they are fully redundant instances. In the event of an unexpected hardware failure that causes the active, primary VM to fail – a secondary, formerly passive VM immediately picks up where the primary left off, and continues to run, uninterrupted, and without any loss of network connections or transactions. This technology will also work across any application any OS without modifications, without scripting, and provides a much more cost-effective way of running mission critical workloads than fault-tolerant hardware dedicated entirely to individual applications. At VMware, we say that “virtual is better than physical” very frequently, and our advanced development work on providing continuous availability for VMs – to enable VMs to keep executing, completely uninterrupted by unexpected hardware failures - is one of the great examples of why this is true. We have taken technology implemented with very complex custom hardware and delivered it for commodity x86 hardware. We believe this technology, and all of the other business continuity benefits of virtualization will drive more and more mission critical workloads into virtual machines because they can enable HIGH
