IOPS

 3.5-inch Fibre Channel SSD features two independent FC-AL ports. These ports may 

be connected in different loops or the same loop. In addition, the drive can send transfers while 
receiving frames on both ports. This capability is called “full-duplex”.

If the ports are 1) connected in different loops, 2) hard addressing is used, and 3) the drive 
interface address is selected through the interface connector, then both ports will seek the 
same loop address. If there are no duplicate addresses on the different loops, both ports 
will use the same address.

If the ports are 1) connected in the same loop and 2) hard addressing is used, the drive 
reads the settings from the connector. If the SCA connector is configured for a hard 
address, only one of the ports will be seen on the loop; only one port can acquire the ID.

If the drive has 1) its ports connected to different loops, and 2) buffer availability, then the 
drive is able to receive transfers on both ports at the same time. This capability is called 
“concurrent port transfers”.

Table 11 summarizes the FC-AL options supported by the drive.
