• Pre 5.5 – No real scale up
• Now with 5.5 we scale up into 64 cores
• x86_64 - 64 bit for more memory is important
• Linux or Solaris best, Windows and Unix also fine
• Big gains on Windows with 5.5
• RAID 10 for most, RAID 5 OK if very read intensive
• Hardware RAID battery backed up cache critical!
- More disks are always better!
- 4+ recommended, 8-16 can increase IO performance if needed
• Memory should be at least 1/3 to 1/10 data size
- The more, the better
