Marking its 20th consecutive quarter of server shipment leadership, HP once again was No. 1 in total server units shipped, according to first calendar quarter 2007 server market figures released today by industry analyst firm IDC. In the high-performance computing market, HP maintained its No. 1 spot for the first quarter of calendar year 2007 with 33.7 percent revenue share. While high-performance computing industry revenue declined 4.7 percent quarter-over-quarter, HP experienced 3.7 percent growth quarter-to-quarter. HP grew overall server shipments by 16.6 percent in the first quarter, growing faster than the top 10 vendors in the worldwide server market. Driven by strong growth across its ProLiant, Integrity and BladeSystem families, HP captured 33.6 percent shipment share in the first quarter, shipping more than one out of every three servers in the world. These strong results were underscored with the fact that HP again tied for No. 1 in worldwide Q1 server factory revenue for the third year in a row.
