Known Issues primarily amount to data errors:
- main memory
- cache ram and CPU internal state
What can be done about these?
My thoughts include
- Use EEC Ram
- Shield the CPU and cache with tungsten because it's a good conductor and IIRC a good radiation shield.
- Use RAID 5 (or RAID 6) disks with some sort of hacked setup to correct errors in place rather than just writing off the whole disk as bad.
- Use ROM disks built out of sold state HDDs with the flash chips replaced with ROMs or just a stack of CD/DVD/HDDVD drives.
Note: I'm not just thinking of embedded system. I'm also interested in high end system right on up to supercomputers if anyone has any info of them.
