    iSCSI MPIO throughput limited to 1G

    gamania Novice

      I have followed the VMware's "iSCSI SAN Configuration Guide" (filename vsp_40_iscsi_san_cfg.pdf) to set up vSphere 4 with software iSCSI MPIO. Round robin is also enabled on the storage to utilize both paths. I can see both paths are active from my Equallogic PS5000X, and are working with active traffic when doing sqoio test. However, the throughput in SQLIO test are maxed out to 1G. Where could the problem be? I imagine the MPIO will result in greater throughput just like what will happen in native Windows set up, but it doesn't seem so.
