FDB has a substantial per-node license cost. It makes sense to beef up the hardware on individual nodes as much as possible first, then scale out to more nodes

- jedberg 12y agoIt would be unfortunate if their pricing model drove poor architectural decisions, but in this case that doesn't apply. I suggested getting more storage by using the same number of nodes differently.
- ansible 12y agoAh, I mis-read your post, and was thinking you were suggesting more nodes rather than more disks. Sorry for that. At any rate, I have quite a distaste for RAID-5, so I agree that it would be preferable to go with the higher RF instead. Even more preferable to me would be to not use RAID-0, if FDB can just use multiple drive partitions as storage directly.
- jedberg 12y agoYeah, JBOD is preferable to RAID if your workload supports it. Less overhead and less things to break.
