cluster tff=2

[olicata]

I have to build a cluster on 1 site, I need to configure tff = 2, how many nodes should I put?

It's hybrid Clarification is not a stretched cluster

Hello olicata,

I assume you mean FTT=2 (Failures To Tolerate).

This requires a minimum of 5 nodes contributing storage as each Object (without striping) will have 5 components (3 data + 2 witness components) thus requiring 5 nodes to be split across.

Also, just so you know, 'Hybrid' refers to a configuration using HDDs for capacity-tier drives (as opposed to All-Flash which uses all SSDs), 'stretched' cluster refers to a multi-site set-up
