Flash Cache: which volume is breaking it?
2012-08-15 05:11 AM
I have a filer with 512Gb FlashCache, please have a look at the graph generated by Performance Manger.
1. Is it ok / normal to have 60% hit rate?
2. How can I tell what volume causes spikes in "miss" ~ every hour? I can not match it against workload of any volume, again looking at PM graphs.

use the following command at ontap prompt:
stats show -p flexscale-access
stats show ext_cache_obj
You will have a better understanding of how flexcache is working.
