Independent Research: IBM iSeries AS/400 vs Windows NT

Lowest Total Cost of Ownership

The IBM iSeries – AS/400 has the lowest Total Cost of Ownership (TCO) of any leading midrange server. On an annual cost-per-user basis, the AS/400 is 63% more cost effective than Windows NT and 42% more cost effective than Unix.

According to IDC, the IBM iSeries has the lowest total cost of ownership among the top midrange servers.

Consider that for 10 users over five years, the savings afforded by the iSeries versus Windows NT is $120,000, and the iSeries versus Unix is $80,000

Fewest Unplanned Outages

Server downtime is costly and frustrating. Just ask Windows NT users, who see an average of 224.5 hours of unplanned outages per year, per server. On the basis of 2,080 work hours per year, that equals an unplanned outage rate of 10.8%. By comparison, the iSeries is 43 times more reliable, with only 5.2 hours of unplanned outages.

Outage Costs per Employee per Year

NT: 224.5 hours @ $20/hr = $4,490/yr per worker
Unix: 23.6 hours @ $20/hr = $472/yr per worker
iSeries: 5.2 hours @ $20/hr = $ 104/yr per worker

Quickest Deployment

The iSeries is about 3 times faster to deploy than Windows NT and Unix servers… and consistently takes less time than planned. This means iSeries users can begin recapturing their investment almost two months earlier:
