You have seen the ads.. Sun is faster, less energy, cheaper...
What does this mean for UPSes?
The IBM Power 595 uses 9900va of power, where the Sun Sparc only uses 1400va
So, instead of having to get a APC Symmetra 16kva system for about $10,000 new or $4995 from me for the IBM
You can get a APC 2200va system for $879 new or $249 from me.
So, if the ad is true, you can get all that performance AND still save $9000 on the UPS.
