问题解答

阵列的最大可配置SSD缓存量与控制器的主缓存大小相关。此图表显示了可为控制器的各种主缓存大小配置的SSD缓存容量:

 

SANtricity OS 11.80GA或更高版本
控制器缓存大小 SSD缓存大小可配置
最多2 GB 1 TB
> 2 GB到4 GB 4 TB
大于4 GB到8 GB 5 TB
> 8 GB 10 TB

 

SANtricity OS 11.70.5R1或更早版本
控制器缓存大小 SSD缓存大小可配置
高达1 GB 1 TB
> 1 GB到2 GB 2 TB
> 4 GB到8 GB 4 TB
> 8 GB 8 TB

追加信息

  • 控制器的主缓存大小将小于控制器安装的内存大小
  • 大小差异因版本和阵列配置而异。
