超融合平台竞争分析-Nutanix与vSAN.pptx

超融合平台竞争分析Nutanix 与 vSAN;无意鼓吹”我们是最好” 世界不是非黑既白 更好的理解和掌握竞争情景;基因决定格局;架构和设计决定成败;VSAN的视野;Web-Scale Engineering… A Different Approach;远景决定能力;vSAN架构上的局限性;无数据本地化能力 无数据分层 – SSD仅仅提供读写缓存 单个虚拟机不能使用超过自身节点外的SSD 写缓存最大只能600 GB，严重浪费SSD容量和性能保证 默认配置，VMDK没有条带化配置(IOPS 仅仅来之2个物理磁盘) 数据重建只能从1个主机和1个磁盘进行，群集规模大小对重建没有意义 数据重建都需要到SSD，即使是冷数据(SSD容易溢出) 在三个节点配置下，如果有节点故障，系统不会重建数据;驳斥VSAN;自愈系统 vs 救火式系统;VSAN 消重和压缩的限制;虚拟化层缺乏存储感知的困惑;没有任何关注情况下如何革新?;;通过参数指标提高竞争门槛;What’s new in 6.6?
