i saw this cable and i am wondering what de purpose of this cable
SAS Cable external SFF-8088 to 4x SFF-8088, 2m
does this mean that i can connect 4 jbod cases to 1 external sff-8088 port of hba card?
an example...jbod case has 16 hdd's and internally connected to internal ports of a sas expander (to sff-8087 ports). but this expander has also external sff-8088 port. so i connect 1 of those 4 cables to this external port of the expander. this setup multiplied 4 times and connected to 1 external port of a LSI 16e hba. thus in totally connecting 16hddx4cables/jbods cases = 64hdd's on 1 external port of a LSI 16e hba. and then this 64hdd multiplied 4x hba ports are 256hdd's in totall connected to 1 LSI 16e hba.
are my assumption right about usage of this cable?
another question...is sas2 protocol fast enough for playing 4k video from jbod case?
