Hi,
The KX Systems website is a bit sparse on hardware recommendations:

Is a powerful server needed to run kdb+?
“It depends on data volumes, but most customers begin with a 4- or 8-core system and grow from there. As the historical database builds up, multi-terabyte storage may be needed, but kdb+ is flexible — using local storage, SANs, or any combination.”

What systems is anyone out there using and what are the recommendations?
How much ram do I need for a kdb Server?
Blades? SAN? NAS? NFS? Intel? …
