Following Broadcom's acquisition of VMware, the file hosting ecosystem changed. Do not download hypervisor images from third-party forums or unverified file-sharing links, as modified ISOs pose significant security and stability risks. There are two official, trusted pathways to acquire verified images. 1. The Broadcom Support Portal (Primary Method)

If you manage a Cisco Unified Computing System (UCS) environment, you know that reliability is non-negotiable. While VMware provides generic ISO images for ESXi, running a stock build on Cisco UCS B-Series or C-Series servers can lead to driver mismatches, storage incompatibilities (especially with the Cisco Virtual Interface Card (VIC)), and unsupported configurations. download cisco custom image for esxi 70 u3 verified

If you are using UCS Manager to centrally manage your infrastructure, Cisco also provides that can be mounted via the service profile. These ISOs contain only the Cisco VIBs (not the full ESXi) and are used to update drivers without reinstalling the hypervisor. You can find those by searching for your specific server model on software.cisco.com and filtering by “Unified Computing System (UCS) Drivers”.
: Keep your UCS firmware and ESXi drivers in sync. If you are doing a clean install, upgrade the firmware to version 4.3.2 (or higher) before installing the custom ISO. If you have an existing system with older firmware (e.g., 4.2.x), it is generally safer to upgrade the drivers first (by applying the custom ISO or offline bundle) and then upgrade the firmware later. In the words of a Cisco community expert: “Newer drivers with older firmware: I have never seen an issue with this combination. What you want to avoid is newer firmware with older drivers.”
