Rackable Systems Announces ICE Cube(TM) Modular Data Center.

Next Generation Containerized Mobile Data Center Environment Features Even Higher Computing Density and Flexibility with Rapid Production Times

SAN FRANCISCO -- Rackable Systems, Inc. (NASDAQ: RACK), a leading provider of servers and storage products for large-scale data centers, today unveiled ICE Cube, the company's new modular data center environment. Designed to augment or replace traditional data centers of any size, ICE Cube features computing density levels of up to 11,200 processing cores or up to 4.1 Petabytes of storage in a standard 40' x 8' ISO shipping container. ICE Cube enables IT administrators to quickly and easily deploy a cost-effective and high-performance data center environment in virtually any location.

Based on Rackable Systems' award-winning Concentro[TM] modular data center design--first deployed in March, 2007--this newest generation of the Integrated Concentro Environment (ICE) features nearly 20 percent greater density levels, a broader choice of container sizes and configurability of Rackable Systems' Eco-Logical[TM] servers and storage, as well as more rapid production times. Customized and built-to-order, ICE Cube can be deployed with Rackable Systems' broad range of space-saving, half-depth servers and storage, including its new V Series line of virtualized servers. With advanced production capabilities, Rackable Systems can design, build and deliver a fully-populated ICE Cube to customers in a matter of weeks.

"ICE Cube changes everything," said Mark J. Barrenechea, president and CEO of Rackable Systems. "The data center is now mobile and modular, achieving reductions in energy and facility costs by as much as 50 percent. And ICE Cube can dramatically reduce deployment times--enabling design to deployment of a fully-functional, built-to-order data center in a mere 90 days or less."

As a mobile, self-contained data center environment that can house up to 1,400 of Rackable Systems' award-winning Eco-Logical rack-mount DC powered servers or storage systems, ICE Cube provides a fully-customizable, energy-efficient and flexible solution for any growing enterprise. It leverages Intel[R] Xeon[R] Quad-Core processors in Rackable Systems' half-depth servers and storage, enabling extremely high density per square foot. ICE Cube's unique, highly-efficient cooling technology can reduce cooling and air handler power costs by up to 80 percent over traditional brick-and-mortar data center environments.

Well suited for a broad range of deployment scenarios--from military applications to disaster recovery scenarios to basic data center expansion--ICE Cube provides tremendous flexibility for expansion to areas in which traditional data center facilities are unavailable, cost prohibitive or cannot otherwise capitalize on alternative energy sources in remote locations. The ability to deploy ICE Cube rapidly and in any location helps enable business continuity, allowing for easy hardware migration and an expedited disaster recovery process.

"We continue to be thrilled with the broad and increasing levels of innovation that the Rackable Systems and Intel collaboration is bringing to next generation data center design. The Intel Xeon processor is specifically designed for this type of energy efficient, high performance modular building block approach, and will help ICE Cube solve the significant density, power and cooling challenges that legacy data centers face today," said Kirk Skaugen, vice president, Intel Digital Enterprise Group, general manager, Server Platforms Group.

Rackable Systems' innovative design breaks down geographic barriers to expansion, enabling units to be deployed in a building block approach--either augmenting existing data center facilities or providing remote data center sites, which can be efficiently managed at the server, rack and container level using Rackable Systems' Roamer[TM] remote management technology.

Features and Functionality

Key features that ICE Cube offers include:

* Leading Density - ICE Cube accommodates up to 1400U of Rackable Systems' half-depth servers and storage in a single 40' x 8' shipping container for total compute capacity of up to 11,200 cores, or storage capacity of up to 4.1 Petabytes;

* Container Flexibility - ICE Cube can now be deployed in 20' or 40' container sizes to accommodate a range of space requirements;

* Cost Reduction - ICE Cube is a fraction of the cost of traditional brick-and-mortar data center facilities housing comparable density levels;

* Power Friendly - ICE Cube leverages reliable DC power technology and Rackable Systems' low wattage servers and storage, while featuring revolutionary, ultra-efficient UPS systems built directly into containers, helping to minimize typical power conversion losses;

* Self-contained Cooling - ICE Cube uses self-contained cooling technology, which can enable a cost savings of up to 80 percent versus traditional data center air handling expenses--while improving system reliability;

* Rapid Deployment - Instant-on, a fully-configured data center can be deployed in minutes when plugged into standard power and network connections for immediate functionality;

* Configuration Flexibility - ICE Cube is available with Rackable Systems' hallmark half-depth Eco-Logical servers and storage--including the award-winning RapidScale[TM] clustered storage--in a broad range of customizable x86 configurations tailored to each customer's specific needs;

* Environmentally Responsible - ICE Cube diminishes geographic barriers to alternative energy sources, reduces excess energy expenditure and is recyclable at the end of its life;

* Highly Mobile - ICE Cube enables a variety of site selection and power options, enabling customers to leverage alternative energy sources such as hydroelectric or solar power, while reducing physical space costs and requirements;

* Disaster Recovery and Security - Offsite systems administrators can take advantage of geographical diversity for redundancy, while providing emergency backup in the event of disasters. No-frills reusable ICE Cube shipping containers discreetly house full data center functionality while providing wireless GPS tracking and alarm/security protection;

* Ease Of Migration - Containerized approach expedites migration of old hardware when upgrading data center equipment.

Rackable Systems will be hosting a touring road show of ICE Cube at Raytheon facilities in the Washington DC and Northern Virginia areas over the coming weeks. It will be on display September 18-20 in Chantilly, Virginia; September 25-27 in Reston, Virginia; and October 2-4 in Falls Church, Virginia. Government organizations interested in a private tour of ICE Cube should contact Freelann Clark from Raytheon at [e-mail].
