I am just starting to understand SAS backplane and HBA. I am a little confused when you have 24 drives connected to only 8 SAS lanes, wouldn't there be a bottleneck if you had to access all 24 drives at once?
Since 8 * 12Gbps = 96Gbps total bandwidth. With 24 SATA3 (24 * 6Gbps) you would need 144Gbps total bandwidth. More if you use SSD SAS drives.
Wouldn't the ideal scenario for a 24 drive chassis is to have at least a backplane with 6 SAS ports giving you 24 SAS lanes? Or is this the case where no mechanical drive can achieve the 6Gbps rate.
