[Bizgres-general] Sizing a server to host Bizgres...

[Luke Lonergan]

Yes, and do you remember the days on Windows when enabling dma was an
experiment to be tried with some fear of data loss, etc?  That¹s why RedHat
was conservative, but that was 8 years ago. 16 bit IDE? Pullease!
Multi-sector PIO transfers, it¹s been safe for 10 years. Interrupt handling
was an afterthought on desktop drives about 10 years ago, it¹s been solid
over the last 8.

BTW, none of these problems happen on SATA drives because they use the Linux
SCSI layer.
