vmware iscsi performance tuning?

[Al-S]

And please keep in mind when using latest builds of DSS, MaxBurstLength variable cannot be set to 16776192 because such value was only supported in iSCSI Enterprise Target (IETD), additionally With reads variable also works only with (IETD).

Max value in SCST for MaxBurstLength is 1MB, 10485760.

In case when you use MaxBurstLength=16776192 and make the update, scripts during starting the system fix the values to default one (262144).

So you may leave MaxBurstLength variable values as the default value or you may use the max value which is 10485760.
