I recently acquired another SAS expander (basically for free...) that daisy chains to my existing expander and have confirmed that FreeNAS can see drives from both SAS expanders in my current configuration. The new SAS expander came with 4x1tb enterprise (Seagate/Dell) drives, which brings the total count of NAS dedicated drives to 8, all of which are 1TB capacity. I am seeking advice/insight into the following questions:
1. Are there any advantages to using both SAS expanders with only 4 drives each, or will performance be the same with more power consumption?
2. Should I just get rid of the SAS expander since the 1TB storage to 1GB RAM rule will likely preclude the need to ever go above 16 drives? (I am in the process of upgrading to 32GB of RAM on the c1000).
My default plan is to put all drives in one expander until I need more room, which may not happen, since I'll likely be investing in drives above 1TB capacity in the future, meaning I could easily get to 32TB of storage by adding 8x3TB drives from here on out. The obvious thought is that heat buildup would be less by diving the drives across 2 expanders.
Thoughts?
