Ah, thanks. After issuing these commands I get better performance with
STGT and iSER. The updated table is as follows:
STGT read SCST read
performance (MB/s) performance (MB/s)
Ethernet (1 Gb/s network) 77 89
IPoIB (8 Gb/s network) 82 229
SRP (8 Gb/s network) N/A 600
iSER (8 Gb/s network) 324 N/A
Can we conclude that with the tested software versions SCST performs
significantly better than STGT on an InfiniBand network ?
Bart.
