looks like broadCON being broadCON.  No wonder everyone who can is jumping ship!  Best bet might be someone on here has the copy you need, what version do you require?

Unfortunatly you need to contact a Broadcom partner to get these bits. Or maybe ask for it on the vmware/broadcom forums. 

as I said BroadCON being BroadCON

Thank you.

I need the following two items:

VDDK-7.0.3.1

VDDK-8.0.3.2

I haven't received any response at all after posting on the Broadcom Community.

i thought I had  a copy of  7.0.3.1 but I can’t find it :-( i’ve logged in to broadCONs dev portal but can’t find anything there either.  It looks like they have changed some stuff and all the links seem to be dead.  Typical BroadCON what a shambles

Can I post both of them? Do I have permission?

I’ve checked both of 2 version:

VDDK 7.0.3.1 — this is the older branch. On the Broadcom Support Portal it lives under the vSphere 7.x SDKs. You'll only see it if your (or the customer's) account has a vSphere 7 entitlement attached, because downloads are gated by license version.

VDDK 8.0.3.2 — this is the 8.0 Update 3 branch, under the vSphere 8.x SDKs, gated the same way behind a vSphere 8 entitlement.

The only sanctioned way to get either right now: log in to support.broadcom.com (the support portal, not developer.broadcom.com) → switch the division selector top-right to VMware Cloud Foundation → My Downloads → find the vSphere SDKs. If the VDDK doesn't show up there, it means your account has no matching VMware entitlement, and that's the real blocker — you'd need your Broadcom account team to sort out access. There's no clean workaround for a missing entitlement; that's a licensing conversation, not a technical one.
