Update Manager Query

Hello,

I am new to Update Manager and have few questions. I am using vCenter 5.1.

1. If I "Configuration Tab" of update Manager and under download settings, I click download now.  Where are these new updates stored?

2. If I create a new dynamic Host Patch baseline, in criteria section of the wizard, under product, it only shows me EmbeddedEsx 4.0.0, EmbeddedEsx

    4.1.0, EmbeddedEsx 5.0.0, EmbeddedEsx 5.1.0, esx 4.0.0 & esx 4.1.0. It does not show ESXi 5.1? (Check Attachment)

Thanks,

Kind Regards - AG
