Three of the world’s largest wireless-network operators have each signed three-year deals to buy HP’s industry-standard ProLiant servers built on Intel’s latest processors, HP announced Tuesday.

Vodafone (UK-based mobile operator that is second largest in the world by subscribers), Verizon (the largest operator in the US) and the company providing mobile services to most of Russia and to several other former Soviet republics Mobile TeleSystems OJSC (MTS) have all agreed to use ProLiant servers as part of their infrastructure over the next three years.

The deal was a result of collaboration between the three carriers with the goals of aligning on product standards and combining purchasing volumes. Each of the customers is using ProLiant machines to further standardize x86 servers in its data centers, HP said.

The latest ProLiant servers HP announced were its Gen8 product family, which includes both Intel- and AMD-based products. This is a full range of server types – from blades to towers – that feature advanced management features, such as tools for power and thermal monitoring and asset tracking.

Servers are not the only thing HP is selling to the three mobile gorillas. The company also provides its Converged Infrastructure solutions to them, it said.

While HP was not clear on which products from the Converged Infrastructure solution category it provided to which of the customers specifically, it includes its pre-integrated cloud infrastructure solution CloudSystem, its Virtual Connect technology, which automatically connects HP servers wo any LAN or SAN without extra mezzanine cards, as well as its 3Par storage solutions.

Both Gen8 and the preceding Gen7 ProLiant server families fall under the Converged Infrastructure umbrella.
