iSCSI target discovery

[ehinkle]

Which is recommended when configuring the iSCSI targets, Dynamic discovery or Static discovery? Is there advantages to doing one over the other?

[jbogardus]

Dynamic discovery is generally the most frequently used method. By specifying the iSCSI Server, all the LUNs on that server which the ESX Host has been given access to will be visible. This makes it a simpler configuration to manage.

With Static discovery the intiator doesn't do any discovery. The list of LUNs the ESX Host should connect to need to be individually specified. This creates an additional management step and the possibility of invalid or out of date entries.

please refer to http://www.vmware.com/pdf/vi3_server_config.pdf;

software iscsi hba, only dynamic discovery supported so far;

hardware iscsi hba,both dynamic and static supported;

for dynamic discovery, if iscsi target ip changed, esx still can find these targets?

If you are using sw iscsi initialisator dynamic discovery is the only way to send targets.

When adding the iscsi target via dynamic discovery if you have two iscsi storage processors, do you add both IP addresses?

[ehinkle]

Never mind I figured it out, I needed to add both SP's so it could determine that there were two paths.

If you want something reliable try Lefthand or StarWind. I`m using the second one - it`s much more cheaper. Try to read how to Increase VMware Availability, and download StarWind Free to test it.
