Terascala, the parallel file systems and Lustre-based high-throughput storage appliance house, has switched horses.

Founder and CEO Larry Genovesi has stepped down to be CTO and the company has brought in Steve Butler as CEO.

Prior to joining Terascala, Butler was CEO of ManageSoft, the enterprise software management firm acquired by Flexera Software last month, and before that CEO of Segue Software, which was acquired by Borland.

His resume suggests he's good at selling the things he runs.

As it happens, the five-year-old company is partnering with Dell on an HPC-targeted Dell | Terascala HPC Storage Solution for Linux clusters meant to scale to support massive amounts of data.

The widgets are available in the U.S. in 30TB, 60TB and 90TB configurations, providing up to 180 Terabytes of fast-scratch storage, and use Dell PowerVault MD3000 and MD1000 storage technology and Dell PowerConnect networking.

IDC predicts the HPC storage market this year will expand about 8% to $3.1 billion. By 2013, IDC expects storage to grow to $4.1 billion or 39% of HPC server revenue, compared to 35.5% in 2010.

IDC also pointed out that "The supercomputer segment for HPC systems sold for more than $500,000, which is dominated by government and academic purchases, actually grew 25% even in the difficult recession year of 2009."
