1) If data availability and redundancy is most important, you would go
So for a 180 TB cluster you would go with a 6 - 8 drives bare-bone?
What about 500 TB?
I see, thanks.
with multiple 2U boxes to minimize cluster impacts in case of any downtime?
My general feeling here is that it depends on the size of the cluster. For small clusters, 2U or even 1U boxes may be ideal. For very large clusters, it is probably fine to use a denser chassis. It's all about the ratio of how many nodes are left to absorb the loss when a single node fails. I don't have any hard numbers, but my instinct is that in production I wouldn't want to lose more than about 10% of my cluster if a node dies.

I've had great experiences with both Supermicro hardware and HP hardware. Products from both companies can work great for Ceph, but they are different companies and have different benefits and downsides. Service, support, and price are all things that may make one or the other a better fit depending on your needs.
2) Barring service and SLA, is it really worth taking HP over
SuperMicro, or it's simply overpaying for a brand?
I see, thanks.
