Planning a Sangfor HCI Deployment: Network and Storage Design Checklist

Intro
Sangfor HCI brings compute, storage, and networking into a single platform, which makes it quick to deploy and simple to manage once it is running. That simplicity depends on the groundwork done before the first node is powered on. In my experience supporting HCI environments, most post-deployment problems are not product bugs. They trace back to decisions made during planning: a NIC layout that differs between nodes, storage traffic sharing links with VM traffic, switch ports that were never configured, or version and hardware compatibility that was never checked.

These problems are frustrating because they often appear weeks later as slow storage performance, random disconnects, or cluster alerts that are hard to link to a root cause. By then, fixing them can mean re-cabling, changing switch configuration, or even a maintenance window.

This post is the checklist I use before every multi-node deployment. It is not a replacement for the official Sangfor documentation, but a practical guide to the points that are easiest to miss. Whether you are a partner engineer, a customer administrator, or someone preparing for your first HCI project, I hope it saves you time and avoids repeat visits.

1. Define the NIC layout per node first

Map every physical port to a role before touching the hardware: management, VM/business traffic, and storage.
Keep the layout identical on every node. Inconsistent cabling is a common cause of hard-to-trace problems.
Label cables and ports so anyone can verify the layout later.

2. Give storage its own network

Keep storage traffic physically separate from VM and management traffic.
Confirm the switch-side configuration (VLANs, link aggregation, MTU) with whoever manages the switches before deployment day, and send them a written port map.

3. Verify before you deploy

Check link speed and negotiation on every port.
Test connectivity between all nodes on each network.
Confirm time sync (NTP) across nodes.

4. Check versions and compatibility

Confirm the HCI version, the hardware compatibility list, and the firmware levels of the nodes.

5. Document what you built

Record the IP plan, port map, and VLANs, and hand them to the customer.

Common mistakes

Cabling that differs between nodes
Switch ports not configured when the engineer arrives
Mixing storage and VM traffic on the same links
Skipping pre-deployment connectivity tests

Closing
A good HCI deployment is mostly decided before installation day. Spending an extra hour on port mapping, switch coordination, and pre-checks can save days of troubleshooting later. I hope this checklist helps you plan your next deployment with more confidence.

I would like to hear from the community: which step do you find hardest to get right, and what would you add to this list? Please share your experience in the comments so we can build a more complete guide together.
