A terabyte of RAM is pretty cheap. Around $12K for the RAM. Last I quoted out a system for VoltDB, the total cost (complete servers with CPU, disk, RAM) came to ~$17/GB to $22/GB.
If you actually have transaction processing at this scale and need that performance, the RAM cost is not a major issue.
