This article has focused on sizing a solution to support a community of users running wintel applications, on stateless Sun Ray appliances. The new SunPCi IIpro card enables Sun Enterprise servers to support the server versions of Microsoft operating systems. Using the SunPCi IIpro coprocessor in coordination with Citrix's MetaFrame XP product, a full solution can be offered to Sun Ray appliances on one server. This article has shown how the sizing tools, used to size a server for each software component, can be used together to size a total solution. Specific sizing "rules of thumb" for a "knowledge worker" load have been developed.
