就是磁盘省电的一些选项。

关于一些限定条件,LZ可以参考这个。

   
What are the conditions for enabling Power Saving on VNX RAID group?
  Product: VNX
  In order for eligible RAID group disks to transition to the low power state, the following conditions must be met:
 
  • Power savings settings for the RAID group and storage system must be enabled.
  • All disks in the RAID group must be qualified and eligible.
  • All disks in the RAID group have been idle for at least thirty minutes.
  • Replication software is not installed on any LUN in the RAID group.
  • The RAID group does not include MetaLUNs.

多谢支持!

这个设置是自动么,开始部分日立硬盘没配置RAID Group,并且只有这部分这个功能是Enable的Yes状态,那这个问题我可以忽略...

关于disk power saving (spin down)这几份白皮书里有详细说明:

http://www.emc.com/collateral/software/white-papers/300013146-unified-storage-fundamentals.pdf

http://www.emc.com/collateral/hardware/white-papers/h6632-clariion-disk-drive-spin-down-wp.pdf

http://www.emc.com/collateral/hardware/white-papers/h6668-clariion-spin-down-celerra-wp.pdf

如果磁盘(或RAID group)在一定时间内(30分钟)没有I/O访问,那就降速甚至停止电动马达起到省电的目的。一般热备份盘或unbound的盘可以考虑开启,一些买来VNX、CLARiiON只用来做周期性备份或轻量文件访问(非上班时间无I/O)的也可以开启。如果是普通的数据库、交互型应用的,在生产LUN上开不开都一样,通常很少30分钟都没有I/O的。
