When it comes to server sprawl, the big picture is bad.
This looks like a pretty good read...
Analyst firm IDC expects the number of servers in the US to grow from 2.8 million in 2005 to 4.9 million by 2009. Data centres "are becoming more and more swollen," causing IT costs to rise quickly, IDC analyst Vernon Turner said at the IDC Virtualization Forum, which was held here last week.
Desert Schools Federal Credit Union in Phoenix expects to cut costs significantly by running VMware's virtualisation software on two two-way, dual-core Opteron-based blade servers, which were installed last week, said Doug Baer, a systems engineer at the firm. Baer said the new systems are expected to handle the workload that is running on the five two-way, single-core Xeon machines they are replacing. "I can hardly imagine buying another server," said Baer, crediting the virtualisation software from EMC's VMware subsidiary. "Once you build your virtual infrastructure, you are definitely slowing down your server proliferation."
