Sparks, Maryland-based Systems Alliance will resell Greenplum’s data warehousing appliance to customers in its mid-Atlantic and Southwestern US states, and provide services as well.

Systems Alliance said it has already signed up a global wireless services provider as its first Greenplum customer.

Greenplum’s appliance combines a massively parallel PostgreSQL open source database with server and storage components from Sun Microsystems.

Greenplum is privately-held and based in San Mateo, California.
