适用场景

  • ONTAP 9
  • ONTAP Select
  • VMware 数据存储库

问题描述

  • 在部署新ONTAP Select集群时、您必须指定适当的存储池容量限制、以便可以安全地部署和使用此集群。
  • 在创建新的Select集群或向现有集群添加容量时、计算存储池开销的方法有所不同。
  • 在计算所需的最小存储池容量时、需要考虑以下注意事项:
    • 要使用的ONTAP Select节点所需的容量。
    • 为ONTAP Select系统后端操作预留的开销:每个节点130 GB - 272 GB
    • 为整个存储池预留2%的缓冲区。

注:

  • 每个存储池中会保留2%的未使用缓冲区、该缓冲区仅用于可用容量检查。
  • 在存储池上创建的ONTAP Select虚拟机会尝试使用精简配置、但受底层存储策略的限制。
  • 如果接受、ONTAP Select不会立即占用指定的全部存储量。
  • 如果ONTAP Select尝试使用已分配给它的存储、而没有足够的可用存储、则会发生数据服务中断。
