vSphere 4.1 upgrade
Hi there,
I am upgrading to 4.1 from 4.0 U1, and I am wondering if using hardware iscsi is better or equal to using the software iscsi solution. Here is some background we have 6 x R610 Servers (2 processors, 32GB ram and 4 x broadcom 5709 1GB iscsi nic) and we have a PS4000X. I have read during the initial setup in 4.0 that I should be using jumbo frames for maximum performance. During the setup of 4.1 the hardware hba's for the 5709 nics I found that it won't accept the jumbo frame configuration and doesn't mount the data stores.
Could we confirm this is correct and that the 5709 doesn't support hardware hba and jumbo frames?
Secondly can anyone tell me if the hardware hba at a MTU of 1500 will keep up to the software hba with a MTU of 9000?
