Thanks for the context 🙂 KVM 8 is our largest VPS plan (8 vCPU, 32 GB RAM, 400 GB disk, 32 TB bandwidth), and there's no plan above it. We don't offer custom configurations either, so 128 GB of RAM on a single VPS isn't something we can provide.
My suggestion for a project this size:
1. Validate on a KVM 8 first. Run your test there and check in hPanel (Backups & Monitoring → Server Usage) how much RAM your system really needs
2. Split the workload. If your system can be spread across servers, you can run several VPS plans, for example app, database and web server separately. That adds up to more total RAM, but it's not a single 128 GB machine
What kind of system is it, and can it be split across several servers?
If you want to test your system, a KVM 8 is a good place to start. If you'd like to try our servers, you can use the code BLACKFRIDAYDISCORD at checkout for an extra Black Friday discount. KVM VPS plans also have a 30-day refund window in case it doesn't fit https://www.hostinger.com/legal/refund-policy>
