Talk about a buyer's market! Microsoft has joined forces with Hewlett-Packard as HP accelerates its targeted raids on Sun customers by promising fully configured systems and specialized services with lower TCO. HP's latest offensive also includes Novell and Red Hat and comes just weeks after a Sun counterpunch offered HP customers "no-risk migration assessments" that were sure to lead to—you guessed it—lower TCO.

Conjuring up images of coordinated carnivores cutting one out of a herd of antelopes or wildebeests, HP proclaims its new four-way partnership will "provide customers with service offerings, incentives and training programs that streamline the migration from Sun to HP-based solutions, while reducing total cost of ownership."

Called "HP CompleteCare," the new bundle of integrated sets of expertise will "ensure that customers' data center environments are fully supported" and will include "proof of concept, initial assessments, application migration, implementation, and total life-cycle services."

This latest hunting party is the latest in a series of offensives HP has staged against Sun's installed base this year and that have intensified since Sun agreed in April to be acquired by Oracle. After that proposed acquisition was announced, HP and IBM and Dell stepped up their recruitment of Sun customers by playing on their concerns over how the new owners might change support, services, and pricing.

After having sand kicked in its face quite openly and aggressively by IBM and HP throughout the summer, Sun early last month stepped up its own counteroffensive against HP by making a slew of promises about what HP customers could look forward to if they'd make the jump to Sun. In a Dec. 1 article called Sun Trying To Snatch HP Customers, we described Sun's efforts to ward off some of the brutal raiding of its customer base in which HP, IBM and Dell were and still are engaged:

Looking to show that turnabout is very fair play, Sun has launched a campaign to snatch customers from HP with a "no-risk migration assessment" aimed at HP enterprise users who "are facing higher support costs, performance and availability issues, and loss of ISV support for critical business applications."

The offer from Sun Professional Services says that Sun's servers, storage solutions, and implementation services will let HP enterprise customers do everything except solve for Pi: "You can reduce complexity and support costs, enhance performance and business agility, improve asset utilization and infrastructure reliability, save money on power, cooling and real-estate and protect your applications, data and business processes."

But for all of that bark, I'm not sure just how much bite is behind the Sun effort to grab customers from HP: a fairly vigorous search of the website for Sun Professional Services failed to turn up any special program for HP enterprise customers, and the only link offered in the press release touting the "Make Your Move" campaign went to a generic registration page. That page made no mention of HP, and only sought contact information from prospects.

But here's the hard truth about Sun:
