Hi, What about this type of blades, which gives you about 12 (commodity) servers in 3U:

That is a solid choice. You can even configure each blade with two 15TBytes SSDs (may not be wise), but that would yield ~430TBytes of SSD across 14 nodes in 4u space for around $150k. -Joe On 8/2/2021 4:29 PM, Max C. wrote: Have you considered a blade chassis? Then you can get most of the redundancy of having lots of small nodes in few(er) rack units. SuperMicro has a chassis that can accommodate 14 servers in 4U: https://www.supermicro.com/en/products/superblade/enclosure#4U - Max On Aug 2, 2021, at 12:05 pm, Joe Obernberger <mailto:joseph.obernber...@gmail.com> wrote: Thank you Jeff. Consider that if rack space is at a premium, what would make the most sense? -Joe On 8/2/2021 2:46 PM, Jeff Jirsa wrote: IF you bought a server with that topology, you would definitely want to run lots of instances, perhaps 24, to effectively utilize that disk space. You'd also need 24 IPs, and you'd need a NIC that could send/receive 24x the normal bandwidth. And the cost of rebuilding such a node would be 24x higher than normal (so consider how many of those you'd have in a cluster, and how often they'd fail).

Dell has machines with 24, 8TByte drives in a 2u configuration. Given Cassandra's limitations (?) to large nodes, would it make sense to run 24 copies of Cassandra on that one node (one per drive)?
