Hi all,

I think about the directly connectable Storage Enclosure Processors (SEP)
which has SAS interface as follows.
  a) The SEPs are wasteful with a SAS port.
  b) It takes several years that the SEPs are released.

Now SATA-2 standard provides the bridge between SATA and I2C. It is called 
SATA Enclosure Management Bridge (SEMB).

I thought it is economical that the expander has a bridge function 
like SEMB. Do you have any plan like that in SAS standard?
