I have an LSI 9207-8i card (2 ports) connected to an expander (Supermicro SAS-216EL, 3 ports) via a single mini-SAS cable, which is connected to a 24-drive backplane (Supermicro BPN-SAS-216EB, able to hold a 2nd expander). There should eventually be 24 SATA3 SSDs connected to this backplane.
Without changing the backplane, what can we do to increase the performance of this system?
Will it help to:
1. Add another mini-SAS cable to connect the 2nd port of the LSI HBA to another port on the expander? (2 cables connecting HBA to expander)
2. Add a second LSI 9207-8i and connect both HBA to the same expander?
3. Add a second expander to the backplane and connect the first (and only) LSI HBA to both expanders?
4. Add a second expander and a second LSI 9207-8i HBA, where each HBA is connected to both expanders?
Thank you for your help!
EDIT: Corrected backplane model to BPN-SAS-216EB (Thanks Rand_!)
