Datallegro did not disclose the amount but said the additional capital would be directed at product sales and marketing.

Datallegro and Intel have also signed a collaboration agreement.

Datallegro is rolling out a turnkey appliance-based system built using commodity, off-the-shelf hardware, an open source operating system (Novell’s SUSE Linux) and an open source database (CA’s open source Ingres).

It’s no coincidence that all the new venture-backed BI and data warehousing start-ups that have recently debuted in the market build all or some of their solutions around open source.

Open source is making the difference between getting funded and not in today’s business climate, notes Datallegro’s CEO Stuart Frost.

After a seed investment of $6 last summer, Datallegro closed a $15m round of funding in May 2005 led by Adams Capital Management (ACM).

Interest in so-called data warehouse appliances is being sparked by much lower price-performance capabilities than conventional high-end data warehousing systems. Datallegro is banking on low cost of its appliance – $150,000 per terabyte (a 3 terabyte system sells for $450,000) to make it the industry leader in price-performance.

Datallegro says its appliance competes against Netezza Corp and NCR Teradata Corp.
