Hi All
I'm interested to know if anyone have done or know a performance comparison between Ms iSCSI initiator and Vmware iSCSI initiator, with multipath enabled.
Which deliver the best throughput? In other words, is best to configure the initiator at VM or at HOST level, from performance perspective?
Thanks for the info,
Carip.
What are you trying to do? Attach storage to the VM or the Host?
It's similar to say "is better a VMFS or a RDM disk?"
From a performance point of view could be a minimal difference.
From a feature point of view you loose some features (for example you cannot use VCB or similar backup on guest iSCSI disks), but you can have new features (for example use storage snapshots or have a Failover Cluster 2008 also on a ESX 3.x).

Thanks,
sflanders,
while reading about MPIO and esxi multipath (both with MS iSCSI target) seems that MS initiator with vmxnet3 net card outperform throughput of ESXi iSCSI sw initiator (Windows 2008 guest). Having a iscsi maped inside a VM have some advantage, so I'm tryin to identify if exist a real advantage in terms of I/O.

Well... MS did much better job
