Avaya Virtual Services Platform 9000 Series or VSP 9000 is a set of modular chassis switches used in enterprise and data center networks, manufactured by Avaya.

The VSP 9000 was targeted at institutions which were suffering from performance limitations, needed to simplify their network infrastructure in a virtualized environment, or required 10 Gigabit Ethernet with the option to scale to 40 or 100 Gigabit Ethernet.

[1][page needed] It is also an option for companies who are looking to reduce the power and cooling cost in order to maximize the cost-effectiveness of their infrastructures; this unit was also designed, and is expected, to have a lifespan of seven-to-ten years.

[2] In 2013 the Olympics network backbone is built with VSP 9000 Switches supporting 30,000 users and up to 54 terabits per second of traffic.

The primary driver for the 9010 Chassis is where there is an exclusive requirement for front-to-back cooling.
