2Gb in each direction. So 2Gb Tx and 2Gb Rx.  There even used to be 1Gb SAN switches about 10 years ago, which were actually 1.0625Gb in each direction. 2Gb is actually 2.125Gb 4Gb is actually 4.25Gb 8Gb is actually 8.5Gb  Each data block (frame) which is sent uses 8/10 translation (ECC like behavior), so the actual maximum throughput is: 1Gb is actually 1.0625Gb = 106.25MBps (Megabyte per second) 2Gb is actually 2.125Gb = 212.5MBps 4Gb is actually 4.25Gb = 425MBps 8Gb is actually 8.5Gb = 850MBps  1MB = 1,000,000 Bytes of course. And all speeds are full duplex, so the named speeds are in both directions !!!
Hi guys,  Can you please let me know 2 Gbps Full duplex SAN connection means 1 Gb in each direction or 2 Gb in each direction.  Pls suggest Regards
