What type of usage does it need to scale for? How many concurrent
connections? What size database? Data warehousing or OLTP-type
workloads? Ratio of reads/writes? Do you care about losing data?
One question that's likely going to be important depending on your
answers above is whether or not you're getting a battery-backed write
cache for that ServeRAID-8K.
