So to wrap it up. According to Will, a supermicro chassis using a single lsi expander connected to sata disks can utilize the wide sas port between hba and the chassis. (like a J4500 Richard mentioned. How much I like these systems (thumper etc), they're way out of my budget.) Will did see more throughput than a single link could handle. But due to insufficient disks no more i/o could be generated to better demonstrate the availability off the wide sas port. I assume the J4500 is using dual expanders. Richard, can you confirm that the J4500 is using an active/active sata mux per drive to allow failover between expanders? Aside from this can you also confirm that a wide sas link between a hba and a single expander can be fully utilized when using sata drives? To rephrase, utilization is independent of the disk type (sas or sata) All disclaimers apply.
