VCF Pre-Deployment Checklist
Every VCF deployment failure that isn't a bug is a missed prerequisite. This interactive checklist walks through every category — DNS records, NTP, networking, hardware, licensing, certificates, firewall ports, accounts — and produces a signed-off PDF you can hand to your project team.
Quick start
- Pick your deployment mode — Proof of Concept (relaxed) or High Availability (full production checks).
- Work through each category — DNS, NTP, Physical Networking, Hardware, Licensing, VCF Installer, Certificates, Passwords, Firewall, Final Pre-Flight.
- Tick items as complete — checklist persists in your browser, so you can come back later.
- Add notes — record IP addresses, account names, ticket numbers next to each item.
- Export to PDF — when complete, generate a signed-off PDF for your team or change record.
When to use this tool
Use this tool:
- Before kicking off any VCF deployment — every install fails for the same reasons (missing DNS records, wrong NTP, hardware not on HCL, firewall ports closed). This catches them before they cost you a day.
- As an audit document — exported PDF demonstrates due diligence to change advisory boards.
- For team handover — the network and storage teams can complete their sections independently before the deployment day.
- For PoC and lab builds too — the PoC mode skips production-only items but still catches the deal-breakers.
How it works
VCF deployment fails when one of about 50 prerequisites isn't met. This tool catalogues every one of them, organised into 10 categories. Each item is either:
- Universal — needed for any VCF deployment
- HA-only — additional production-grade requirements (multiple DNS, redundant NTP, certs from real CA)
Choose PoC mode to hide HA-only items for a faster lab walkthrough. Choose HA mode to see everything required for production.
Your progress is saved in browser local storage — close the tab and come back later, work resumes where you left off. Export to PDF when done for an auditable record.
Step-by-step walkthrough
1. Pick deployment mode
At the top: Proof of Concept (PoC) for labs and demos, High Availability (HA) for production. HA mode adds items like redundant DNS, secondary NTP, real CA-signed certificates, and resource sizing checks. PoC mode skips them so you can build a lab faster.
2. DNS Records
Every VCF appliance and ESXi host needs both forward (A) and reverse (PTR) DNS records. The checklist enumerates them by component:
- ESXi hosts (one per host)
- vCenter Server appliance
- SDDC Manager
- NSX Manager (×3 + VIP for HA)
- VCF Operations / Operations Collector / Automation
Use the DNS Zone Designer to generate all the records, then check them off here as you verify resolution from a test workstation.
3. NTP & Time Sync
Time skew breaks SSO, certificate validation, and clustering. Verify NTP servers are reachable, accurate, and configured on every appliance. HA mode adds: redundant NTP servers, time skew monitoring.
4. Physical Networking
VLANs configured on switches, jumbo MTU end-to-end, port-channels/LACP set up, BGP peering ready for NSX edges if applicable. The Network Config Generator produces the switch configs; this checklist confirms they're actually deployed.
5. Hardware & ESX
Each host on the VCF HCL, BIOS settings reviewed (VT-x/AMD-V, EPT, performance profile), TPM 2.0 if using vTPM, NICs at correct firmware level, drives meet vSAN requirements. The Host Sizing Calculator validates host count first; this confirms each host is actually fit for purpose.
6. Licensing
VCF licenses present in the Broadcom Business Console, sized for your core count. Distinct from per-product licenses (vCenter, NSX, vSAN) — VCF uses a single SKU at the right tier.
7. VCF Installer
The Cloud Builder appliance (or VCF Installer in 9.x) downloaded, deployed, reachable from the management network, with the right version for your target VCF release.
8. Certificates
For HA: certificates from a real CA, with SANs covering every component FQDN. For PoC: self-signed is acceptable but document the security exception. Microsoft AD CS, Let's Encrypt (with appropriate ACME automation), or commercial CA all work.
9. Passwords & Accounts
VCF 9 enforces minimum password lengths (15+ chars). Document the password vault, set per-component passwords (don't use one global password for prod), have the SSO admin and AD service accounts pre-created.
10. Firewall — DNS & NTP Access
Common gotcha: management network can't reach corporate DNS or NTP because of segmentation rules. Verify each port and protocol explicitly — use nc -zv dns-server 53 from the management VLAN.
11. Final Pre-Flight
The last-mile items: maintenance window approved, change record raised, stakeholders notified, rollback plan documented. These are the meta-prerequisites — easy to forget when you're focused on the technical ones.
12. Export PDF
When everything is ticked, click Export PDF. Get a printable document with each item, your notes, the sign-off date, and a unique deployment reference. Drop it in your CMDB/change record as evidence.
Common mistakes
ntpq -p or chronyc sources, not just "I configured the server."
nslookup from the right network.
