It looks like the bidding war for 3PAR could be over. Dell has just issued a release indicating that it will not increase its most recent $2 billion proposal to acquire 3PAR, and the company’s has ended acquisition talks for the data storage company. Dell is entitled to receive a $72 million break-up fee from 3PAR upon the termination of its merger agreement.

This morning, HP upped the ante today with an offer worth $33 per share or $2.4 billion. 3PAR has accepted HP’s bid. Dell also said that it’s improved offer included a proposed commercial relationship and an increased break-up fee.

It looks like we’re back to square one again. Dell has matched HP’s $2 billion offer to buy 3PAR, and HP upped the ante today with an offer worth $33 per share or $2.4 billion. 3PAR has accepted HP’s bid.

Dell had previously signed an agreement to acquire 3PAR for $18 per share or $1.13 billion, with a provision for matching competing bids. HP then effectively outbid the company and offered $1.6 billion, but Dell matched that offer yesterday, after which HP made a renewed bid for $1.8 billion. HP then offered $2 billion last Friday.

Cisco this morning announced its intent to acquire privately-held Arch Rock, which specializes in IP-based wireless sensor network technology with a focus on energy and environmental monitoring and Smart Grid applications.

Financial terms of the transaction are not being disclosed.

When Salesforce.com bought crowdsourced business contact database Jigsaw for $142 million earlier this year, the CRM giant said that it would combine its suite of applications with Jigsaw’s model for the automation of acquiring and keeping up-to-date business contact data. Today, Salesforce is unveiling Jigsaw’s deep integration into the company’s platform, Jigsaw for Salesforce CRM.

Jigsaw will now deliver real-time updates to contact and company information within Salesforce CRM through communication platform Salesforce Chatter. Jigsaw, which uses a Wikipedia-style crowd-sourcing model to bring in data around business contacts, has been incorporated into CRM applications to provide on-demand data, and analytics on the health of data and on usage.

Electronic payment solutions provider VeriFone Systems this morning announced it has acquired the assets of WAY Systems, a provider of mobile POS solutions and gateway services for mobile merchants.

The purchase price consisted of an upfront payment of $6 million and an earn-out payable in one year of up to an additional $3 million dollars should certain performance targets be met.

VeriFone says the acquisition will not have a material impact on its financial results.

At VMworld today, VMware has announced that it has acquired two enterprise companies today–IT performance analytics company Integrien and TriCipher, an authentication system for cloud hosted SaaS applications. Both acquisitions are expected to close in the third quarter of 2010. Financial details of the transactions were not disclosed.

TriCipher’s myOneLogin is an on-demand identity and access management service that allows users one single sign-on to more than 4,000 apps, including Salesforce, WebEx and Google Apps. The company has raised $33 million to date. TriCipher’s technology will be added to “multiple VMware initiatives, including identity-based security, integration of hybrid clouds and managed access to SaaS application from any device, where and when a user needs it.”

In a short amount of time since its launch in April, 2009 and its redesign a year later, realtime analytics startup Chartbeat has gained an impressive following of more than 2,500 paying corporate customers. All of this was done so far with 5 employees, led by general manager Tony Haile.

Now, the betaworks-incubated company has gained an impressive roster of investors in a $3 million Series A financing. The round was led by Index Ventures, and includes some serious superangels such as Ron Conway’s SV Angel, Chris Sacca’s Lowercase Capital, Chris Dixon’s Founder Collective, Lerer Ventures, O’Reilly AlphaTech Ventures, Freestyle Capital, betaworks, Jeff Clavier’s SoftTech VC, and Jason Calacanis. With the funding, Chartbeat will be spun off as its own separate company, just as betawork’s bit.ly was before it.

Apptio, a Bellevue, Washington-based provider of SaaS-delivered Technology Business Management solutions this morning announced that it has closed a $16.5 million Series C round – the company has now raised up to $37.5 million in venture capital.

Yottaa, web analytics and performance platform, has raised $4 million in series A funding from General Catalyst Partners, Stata Venture Partners and Cambridge West Ventures.

As I was writing this, news of the HP / Dell bidding war for 3PAR broke on the front page of Yahoo. This made me laugh, as it typified just how crazy this story has become—few things outside of a bidding war will make a storage acquisition sexy enough to make mainstream news.

At $30, HP’s current offer is the sixth bid, a 200 percent premium over 3PAR’s previous $10 share price. Not only is this insane, but it’s also nearly unprecedented in M&A history. And since 3PAR is trading above $32 the market thinks Dell will bid even higher.

First Off, Is 3PAR Really THAT Unique?

Yes and no.

3PAR is a classic disruption play, its value proposition based on the premise that unused storage is wasteful—often times just 10% to 25% of allocated disk space is actually used.

3PAR’s “thin provisioning” technology enables disk space to be allocated only when applications need capacity, greatly reducing IT management costs. Think of it as storage on a just-enough and just-in-time basis.

In the cloud era, pre-allocation of storage is especially wasteful, because on-demand storage and computing services delivered via the internet have wide variability and less deterministic usage patterns. This makes 3PAR a great fit for data centers, and it’s partly why the technology is suddenly perceived as very valuable.
