Virtualization software developer ScaleMP on Tuesday announced that it has raised $8 million in a Series D round of venture capital.

The Herzliya, Israel- and Cupertino, Calif.-based company will use funding to try to boost sales of its high-performance clustered computing technology and expand into lower-end systems for core business applications. ScaleMP turned to insiders Sequoia Capital and Lightspeed Venture Partners, both of Menlo Park, Calif., TL Ventures of Wayne, Pa., and ABS Ventures of Waltham, Mass., for the additional funding. ScaleMP founder and CEO Shai Fultheim, who said the funding will be the company’s final private round, noted that the technology maker won an increase in valuation from its Series C round last year and opted not to take the deal to new investors.
