iSCSI Multipathing

[John_S1]

Is this feature being included?

Presume you mean the S/W iSCSI initiator because the H/W ones already support it under ESX 3.5. If you do, I think the answer is yes, in fact I think 3.5 does this since Update 2 or 3....

Hi John

When you say iSCSI multipathing are you askingif the iSCSI s/w initiator supports iSCSI CIDs? As other posters have said, even in 3.5.x iSCSI load balancing / redundancy is supported. One of the best decks to seek out (over and obove the iSCSI SAN Config guide) is "TA2213 - VMware Infrastructure 3 Storage: iSCSI Implementation and Best Practices" presented at VMworld 2008.This deck covers some very good implementation specifics around load balancing and multipathing configurations.

In vSphere we have made many iSCSI improvements. For example we have ways of setting up the ESX iSCSI initiator to use each port to establish a session to a target. This means more paths for load balancing or failover. This is documented in the new iSCSI SAN config guide for vSphere which will be online soon.

hope this helps

iSCSI Multipath (MPIO) should be included as far as articles/blogs described so it would be yes and its not a big features that would exclude from vSphere 4.0 though!
