DEEP FREEZE™

The Deep Freeze™ blade server cooling concept is the chief component of
an overall data center design strategy. It is a “cold-plate” technology
evolution that is both “closed-loop” and “chassis-based”, representing the
most efficient cooling design in the market.

It is an independent (after-market, retro-fit product), closed cooling
system (100% self-contained), based on cold plate technology
(metal composites as the cooling structure), using ionized water (non-
damaging electro-sensitive fluid) circulating through a chassis-based
(an actual blade-server component, replacing the relatively inefficient
fan) cooling design.

Beneficial Highlights

As a product, Deep Freeze™ is an
•Independent unit
•Based upon a Retro-fit design
•Designed as an after-market unit serving the $6B blade server industry

1 A blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades.
Each blade is an individual server, often dedicated to a single application. The blades are literally servers on a card,
containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adaptor (HBA)
and other input/output (IO) ports. Blades typically come with two advanced technology attachments (ATAs) or SCSI
drives.

within the hardware's operating limits.

3 Blade servers allow more processing power in less rack space, simplifying cabling (up to an 85% reduction) and
reducing power consumption. The advantage of blade servers comes not only from the consolidation benefits of housing
several servers in a single chassis, but also from the consolidation of associated resources (like storage and networking
equipment) into a smaller architecture that can be managed through a single interface.

4 U is the standard unit of measure for designating the vertical usable space, or height of racks (metal frame
designed to hold hardware devices) and cabinets (enclosures with one or more doors). This unit of measurement
refers to the space between shelves on a rack. 1U is equal to 1.75 inches. For example, a rack designated as 20U,
has 20 rack spaces for equipment and has 35 (20 times 1.75) inches of vertical usable space. Rack and cabinet
spaces- and the equipment which fits into them- are measured in U.

Benefits of Closed Loop Cooling

There are basic fundamentals to contemporary data center management: (1)the
higher power consumption of modern blade servers produces more heat 6; (2)
almost all power consumed by rack-mounted equipment is converted to sensible
heat; (3) which increases the temperature in the environment.

A 2010 HP Technical Study7 surveyed the various cooling strategies and the effects
upon a representative example of power consumption in 42U IT equipment rack:
ProLiant DL160 G6 1U servers (42 servers @ 383 W per server). The cooling
requirement was computed:

54,901 BTU/hr ÷ 12,000 BTU/hr per ton = 4.58 tons

HP determined that the increasing heat loads created by the latest server systems
require more aggressive cooling strategies than the traditional open-area approach.

Power (kW per rack)

6 The sensible heat load is typically expressed in British Thermal Units per hour (BTU/hr) or watts, where 1 W
equals 3.413 BTU/hr. The rack’s heat load in BTU/hr can be calculated as follows:

Heat Load = Power [W] × 3.413 BTU/hr per watt

In the United States, cooling capacity is often expressed in "tons" of refrigeration, which is derived by dividing the
sensible heat load by 12,000 BTU/hr per ton.

Deep Freeze™: A Comparative Study

In October 2010, Harcore Computer engaged a Third party vendor to develop
construction budgets for two 3.2 megawatt datacenters: one using air-cooling
architecture and the other equipped with Liquid Blade™ servers. In that study of
equivalent compute power facilities, each datacenter was designed to house 6,397
servers utilizing the same 2-CPU-per server technology.

Not surprisingly, the Liquid Blade™ servers significantly outperformed its
competitor in the three key areas: physical space needs, power density and cooling
load.

In June 2011, Deep Freeze™ was comparatively tested, using the same
methodology and criteria. The results are as follows:

Comparative Capacity

Deep Freeze requires far fewer physical servers due to virtualization methodology.

Cooling Load

As each source of heat generation is examined and compared, the cooling load of the
exterior walls, host, lighting servers and the UPS system were accounted. As
demonstrated in Table 4, the chiller capacity for both the Liquid Blade™ and Air-Cooled
suites is substantially greater than the chiller-less solutions- the primary reason being
that Deep Freeze™ facilitates a smaller footprint to cool, while still being able to
maintain the data center computing capacity.

Power Consumption

Comparing the Deep Freeze™ design with the Air-Cooled and Liquid Blade™ suites
illustrates that the cost from auxiliary equipment is significantly higher.

Construction Costs

Table 6 compares construction costs. Though all suites have identical computing
capacity, the capital costs to construct both the Air-cooled and the Liquid Blade™
Architecture is, on-average, 175% higher than the Deep Freeze™ suite.

Total Cost of Ownership (TCO)

The Deep Freeze™ approach to data center design, architecture and cooling
methodologies (after-market, retro-fit design) results in a significant overall savings in
estimated TCO. As a retro-fitted, after-market product, Deep Freeze™ units
(replacing the fans installed in blade-server manufacture) will substantially decrease
the TCO due to power efficiencies realized and cooling expenditures reduced.

SIPNOC CASE STUDY
Antonis Valamontes, President, Mobee Communications, LTD

Mobee Communications, Ltd contracted NGN Data Services in 2010 to deploy the
Deep Freeze™ product in their SIPNOC and to design a Tier-3 class data center in
the United States. The data center had to reliably support a 1500 server computing
capacity, while integrating solar and natural gas options as part of a self-sustaining
micro grid design within a 1500 sq. ft. environmental footprint.

Mobee Communications, LTD is a venture-backed start-up that offers Mobile IP
telephony through its Virtual SIPNOC design. By designing their SIPNOC site with
Deep Freeze™ technology, NGN Data Services provided Mobee with the
confidence that Mobee’s environmental needs regarding power, cooling, humidity
and micro grid capability would be met.

The primary goal was to build a self-sustainable facility that could operate efficiently
on and off the grid. Building the facility in Florida presented its set of unique
challenges due to the intense heat and humidity levels. NGN’s solution was to
integrate solar energy and natural gas power generation as the primary sources of
energy, while designing the grid as a backup system; i.e., what could be considered
an “on-grid UPS”; making the grid available should we choose to use it, but not
mandatory.

In effect, NGN created the “micro grid”. The micro grid approach is extremely cost
efficient due to its ability to build excess energy and then push it to the grid.
Everything produced in the system is made for consumption and not for return.

The design incorporates a two-shell building- a building within a building- creating a
6” air pocket in between the outer and inner walls. The purpose of this approach
was to create a natural insulator- the same way feathers create tiny air pockets in
sleeping bags and comforters to insulate and reduce the escape of heat. For the
under-lining of the roof space, NGN used an “icing” approach, to create an R-factor
and further insulate the building to prevent any outside air from entering the
building.

The need to retain the computing capacity in a confined space, as well as Mobee’s
specific requirements for virtualization, made the HP Matrix blade system with the
C7000 enclosures our top choice. The HP Matrix’s superior

16

DEEP FREEZE™

energy management solution aligned perfectly with the NGN Data Services green
energy data suite model- and by combining it with the Deep Freeze™ solution-
cooling optimization with no additional energy consumption costs were achieved.

While designing the server room NGN isolated the servers in their own space.
Every other accessory, hardware and storage device was designated for
assignment to a smaller space with a controlled air environment. When completed,
the network had an estimated storage capacity of 850 terabytes and a computing
capacity of over 900 virtual servers- all with dedicated NIC interfaces.

The data center server room where heat is generated by the blades is referred to
as the “hot room”; the adjacent room where the storage and UPS are located is
referred to as the “cold room.” The temperatures in both the hot and cold rooms are
maintained at a constant 70F. The temperature is controlled electronically by
variable airflow vents located throughout the building.

17

DEEP FREEZE™

Since the Deep Freeze™ modules were deployed to extract heat at the CPU level,
the need to use large heavy chillers to cool down the server space was eliminated.
NGN anticipating the higher heat/temperature of the server room designed the
adjacent room to act as a natural heat exchanger and divided the two rooms with a
glass wall- resulting in an efficient heat “exchanger” incorporating an holistic
method of temperature control that required no additional energy consumption. As
a result, the glass became a natural heat exchanger transferring 14,000BTUs/hr of
heat, the equivalent of cooling 1900 virtual servers or two full racks of eight C7000
enclosures. NGN also selected a green, carbon-neutral fire suppression system
called Aero-K that creates zero ozone depletion, zero ecological hazards and zero
contribution to global warming.

A main objective of Mobee Communications, LTD was to become a premier mobile
IP carrier and to operate a globally distributed system. Our need for extensible grid
computing in a totally virtualized environment that could be rapidly deployed
anywhere in the world, with no loss in reliability or performance, was actualized by
the Deep Freeze Technology Corp’s green energy micro grid model.

green energy data centers. Deep Freeze’s™ “plug & play”,, retrofitted liquid cooling
technology provides an after- market, close-looped liquid cooling solution at the
CPU level. Deep Freeze™ obviates the need to replace existing blade servers and
reduces dependencies upon external CRAC architectures.

Deep Freeze™ technology is the prime cost-effective cooling technology in the
industry today, representing the paradigm shift in deploying and cooling high-
performance computing environments. No other cooling method delivers such a
marked reduction in cost, energy consumption and space, simultaneously providing
the ultimate green energy eco-friendly data suite solution.

Beyond the benefits of Deep Freeze™ as the ultimate unified solution to cooling
optimization and overhead cost reduction, the virtualization methodology and “green
data center architecture” saves money, increases computing power and conserves
energy. By offering environmentally and spatially conscious solutions, Deep
Freeze™ nano-chiller technology has become the next evolution in green energy
data centers.

The Deep Freeze™ CPU chilling technology + the NGN virtualization methodology
+ the NGN “green” Data Center architecture model = an across-the-board solution
for reducing costs, and operating with an environmental footprint of high
performance computing. Benefits include:

• Environmentally-friendly approach/design
• Enhanced space, performance, efficiency and liquid cooling
• Energy selective- deployable in areas where energy is limited or expensive
• Increases capacity of existing stand-alone data centers
• Designs can be rapidly deployed as a “one-offs” or in pod-like units
• Ideal for advanced military applications or natural disaster recovery efforts
