问题解答

  • 这取决于固件是脱机(并行)还是联机升级。
  • 驱动器固件下载操作的时间:
    • 如果在24驱动器系统上更新所有驱动器、则并行驱动器固件下载操作可能需要长达90秒才能完成。在较大的系统上、执行时间略长。
    •   每个驱动器大约需要两分钟才能完成联机驱动器固件下载操作。实际时间取决于多种因素、包括以下因素:
      •  存储阵列上的I/O负载以及联机固件下载操作期间发生的I/O活动量(写入量大的工作负载会发生原因增加联机固件下载时间)
      • 参与下载的驱动器数量
      • 提高性能
      • 参与下载的驱动器上的卷数量和卷大小
      • 关联磁盘池或卷组的RAID级别

注意: 要完成升级、SSD缓存驱动器必须脱机并暂停。
