I would never automatically assume that consolidation equals Linux on System z. Consolidation to z/OS is also quite popular. Or, said another way, if you're a new z/OS customer then by definition (and automatically) you're probably enjoying huge consolidation benefits. We sometimes forget that and/or take it for granted.
I don't know exactly how many frames BC Card is installing, but I can make a safe bet: to support the same (or more) workloads it'll be far fewer machines. This is z/OS we're talking about here, and you just don't need many machines. A couple (in Parallel Sysplex) at the primary site plus one at the DR site is a very nice installation indeed -- and can grow to be enormous (in workload terms) without increasing the machine count.
