Lee - Thin clients have enough smarts to connect but typically not enough to do much on their own, so without a high speed network connection they are useless. A study done last year in several large and medium size businesses using thin clients addressed this issue. 1 - loss of "thin client" capability because of network problems accounted for less than 3% of all downtime. 2 - loss of capability on "fat clients" because of network problems amounted to about 2% of all downtime. not a lot to differentiate there. But elsewhere in the study, they pointed out that "fat clients" had more than 20 times the downtime of the thin clients - so taken from that perspective, any thin client network problems appear to be insignificant. Some of the "fat client" downtime areas were: - loss of service because of configuration conflicts or incompatible software accounted for more than 20% of downtime - loss of service due to disk failure or disk problems accounted for 15% of downtime - The combination of these two factors alone gave "fat clients" more than twice the total downtime of "thin clients". Lack of downtime (through simplification of the configuration, and reduction of potential downtime sources) is one of the big reasons to use a "thin client". Many thin clients have the ability to support multiple network interfaces. When things are working right, the network traffic is shared among the interfaces. If there is a network or interface failure, the remaining interface provides service. There are still many reasons to use "fat clients" - especially if compute-intensive tasks like image rendering or modelling are involved - but increasingly, the data suggests that for most routine "office productivity" tasks, as well as the dedicated tasks we have discussed, "thin clients" provide more than twice the availability at about 20% of the overall cost of ownership. Another source of "thin clients" is older machines which are not competitive as stand-alone PCs but which can easily do the thin client job. However, older machines also have lots of potential downtime components so although the initial capital cost may be low, the overall ownership cost for "retreaded" old PCs is actually not much better than new PCs.
