onservation of the environment and rising power needs have become a growing concern for the enterprise computing community. Technology continues to advance, delivering more processing power than ever before, but in the process it can tax the power and cooling infrastructures in place. In addition to this, as data centers grow the space needed to house and cool them expands, consuming valuable real-estate and using additional resources. IT managers are already paying attention to the return on investment associated with acquiring more energy-efficient equipment but the advantages of a green data center doesn’t stop there. Green data centers don’t just save energy and reduce overhead; they also improve community relations and provide healthy, eco-conscious environments. CIO magazine states “typical data centers consume up to 3% of all the power generated annually in the U.S. That’s equivalent to the electricity needed to power the state of Michigan for one year.” With the help of non-profit organizations such as The Green Grid, Verari Systems® has addressed

environmental issues by employing a company initiative in support of energy efficiency. Verari Systems is promoting the adoption of eco-efficient standards and technologies used by data centers and other computing environments. Through distinctive innovation, Verari Systems has developed and sent to market a revolutionary blade-based server platform that utilizes our patented Vertical Cooling Technology™ and provides unrivaled power efficiency matched with unsurpassable computing density. The best way to harness all that this technology has to offer while keeping costs down and protecting our environment is to think green. Verari Systems’ BladeRack® 2 is built on the industry-leading technology that makes this possible. Verari Systems has made environmental responsibility a manufacturing priority by increasing the overall energy effectiveness of all our product lines, keeping the vision of the green data center in mind.

Patented Vertical Cooling TechnologyTM
The BladeRack 2 was built specifically to solve the data center cooling problem. Verari Systems patented Vertical Cooling Technology is a cooling system that creates a high velocity stream of air driving away hot air created by high performance components and power supplies. Many cluster installations utilize traditional front to back cooling, which creates hot and cold air aisles in the data center as well as causing hot spots that lead to system failure. Front to back cooling draws cool air in through the front of the server and pushes it out the back. Unfortunately, because heat rises, the cool air becomes warm as it enters the upper rack, resulting in inefficient system cooling. This method of cooling also wastes valuable data center real estate by requiring empty rows for cooling and heating. Patented Vertical Cooling Technology in the BladeRack 2 is driven by four levels of fans to maintain intense airflow. The fans used by the BladeRack 2 to initiate vertical cooling are truly cutting edge. These 120mm fans are more efficient at moving air than the smaller fans commonly found in server racks and require less wattage per node.
Traditional Front to Back Cooling Conventional servers and blades are starved for cooling, leading to high failure rates, increased power consumption and reduced density per rack.

Power Efficiency
Energy efficiency savings add up quickly. A watt saved in power consumption saves a watt in cooling. At over 83% total efficiency, the BladeRack 2 is the most power efficient blade-based solution on the market today. The BladeRack 2 converts traditional AC power to more efficient DC power; it is a solution universal to all existing data centers. The Power Distribution Module (PDM) is used to take 480 volts off of the grid and step it up to 800 volts DC power. Lower power requirements at the rack level can mean power savings of up to 35%. BladeRack 2 accepts native power from the power grid. Its 98% power efficiency at the rack level allows it to turn the power into compute cycles without expending excess wattage on cooling any unnecessary heat. Power efficiency will play an increasingly important role over the next several years, as processor wars heat up and the trend towards data center consolidation continues. AC power supplies are often between 68% and 75% efficient; therefore; a server that needs 375 watts would draw about 535 watts of external AC power. In comparison, Verari Systems’ BladeRack 2, with its DC cabinet powered by 480 volts AC data center power, is 90% efficient at the system level, which means that the same server would draw only 416 watts of external AC power. The AC to DC conversion that occurs within the BladeRack 2 infrastructure translates directly into more efficient power usage, especially for the newest and highest watt processors.

Typical 1U power distribution With typical blade configurations, power is lost not only at the UPS but also on the way through the power distribution unit. A 256-node cluster is spread over eight cabinets.

Verari BladeRack 2 power infrastructure Verari Systems’ Direct Power Architecture™ uses native 480V power, avoiding the power loss that occurs with typical distributed power distribution and increasing server density.

Virtualization - Enabling Next Generation IT Infrastructures
A top priority for most IT organizations is improving operational efficiency. Their desire is to reduce TCO while also reducing the complexity and increasing the flexibility of their infrastructure, and doing so within limited floorspace, power and cooling constraints. Blade servers and virtualization each confront these issues in their own right. But, in combination their value is compounded, providing an exceptionally compelling solution. System consolidation, a key industry trend, is directly addressed by the BladeRack 2 product line and our roadmap takes virtualization support to the next level and further enhances the BladeRack 2 offering as a consolidation solution. Several dimensions of virtualization comprise the Verari strategy: server, desktop and storage. Server Virtualization - Verari is currently developing virtual-ready blade form-factor servers for its BladeRack 2 product line that are optimized for VMWare’s ESX operating system, and will meet or exceed all of the VMWare required certifications. These blades will offer a variety of processor capabilities, memory capacity and storage strategies, both diskful and diskless. Verari virtual-ready blades will also be highly effective for use with other hypervisor offerings from vendors such as XenSource and Microsoft, as well as other leading compute virtualization products. Our managment software, Verari Command Center™ (VCC), will directly recognize and support Virtual Machine-based blades later this calendar year. Combinations of physical and virtual servers will be seamlessly manageable from a single interface, including the ability to manage, configure and monitor virtual machines on physical machines based on ESX. Furthermore, VCC will be complementary to VMWare’s VMotion technology, for clustered ESX solution environments. Additionally, Verari is working closely with third-party vendors to offer an additional dimension of server consolidation that enables server pools, failover and SAN provisioning of Verari BladeRack 2 products at present. Storage Virtualization - Verari is delivering utility and high performance storage solutions with industry leading density in a single rack. The BladeRack 2 Storage Subsystems offer the capability to provide up to 24 Terabytes per subsystem, and 432 Terabytes per BladeRack 2 enclosure. These Storage
BladeRack® 2 with VerariIP Diagram Utilizing a centrally located BladeRack 2 configured with powerful workstation blades, information for all traders is easily accessible with no apparent delays. Each user has controlled access via passwords. Maintenance and upgrades are quick, efficient and painless for IT personnel.

Subsystems will be made available with SAN and NAS configurations, supporting storage virtualization strategies and a “Storage Centric Architecture.” Storage Centric Architecture is a key component to consolidation, and complements both desktop and server virtualization efforts underway at Verari. Both “utility storage” and “high end storage” solutions will be offered within a Verari platform. As a further consolidation benefit, BladeRack 2 racks can support heterogeneous combinations of compute, storage and back racked desktop blades in a single rack. The ability to mix and match infrastructure supports the model of a “Data Center in a Box,” including but not limited to the ability to shape the total power density of a data center around this efficient, flexible platform. Desktop Virtualization - Verari has an aggressive development program underway, with plans for a near future release of desktop virtualization for its BladeRack 2 racks. “Back racking” of PC desktops will be supported which enables desktop users with multiple screens to have a seamless compute environment, while all the benefits of cost-of-ownership of the BladeRack 2 systems apply to the PC hardware itself, which is enabled through blade servers. Basic and advanced connection management strategies will be offered, enabling hundreds to thousands of desktops to be virtualized and consolidated.

Computing Density
Empowered by Verari Systems patented Vertical Cooling Technology, the BladeRack 2 blade server platform is an innovative cluster concept that delivers the most computing power in the smallest form factor possible. The greater the density of a system, the greater the heat production from microprocessors and power supplies; which are the two biggest heat producers in servers. Processors alone are responsible for 75% to 80% of the heat that needs to be dissipated. The glaring downside of front-to-back cooling is that it simply won’t evolve to handle the next generation processors at current density levels. Our high density blade servers help reduce the space requirements within the data center, and our patented Vertical Cooling Technology virtually eliminates data center hot spots. The BladeRack 2 allows for unrivaled density by placing the rack directly on top of the perforated floor tiles the need for hot air aisles in the data center is eliminated. This efficiency allows the customer to maximize their real estate investment by getting the most out of their square footage.
