Themis Computer has developed a breakthrough in scalable
computing for mission-critical systems. By housing commercial
computing resources in a standards based, purpose-built enclosure,
the Themis Slice-CT™ provides resilience with superior
thermal and kinetic management. This open and modular design
allows for spiral technology refresh, preserving computing
infrastructure investments for complete lifecycle management.
Themis' Slice-CT accomodates shock and events up to 20G at
20ms without external isolation. Themis Slice-CT blade servers
provide thermal footprint headroom to accommodate aggressive
scaling of commercial microprocessor core density, speed and
power.
Themis’ new Slice-CT blade server is designed for applications
that need a compact, lightweight computing solution that must
operate in demanding environments. Slice-CT uses commercial
off-the-shelf components to bring blade server efficiency
and total cost of ownership to environmentally challenging
applications.
Industry Leading Computing Density
- A 4RU Slice-CT subrack can support up to 12 sockets
(48 Opteron® Cores) or 120 sockets (480 cores) per standard
42RU rack.
- A 10.5RU Slice-CT subrack can support up to 36 sockets
(144 Opteron Cores) or 144 sockets (576 cores) per standard
42RU rack.
Innovative Slice-CT Thermal and Mechanical Design Features
• Rear blowers are integrated into each blade
• Light alloy clamshell design
• Provides mechanical rigidity
• Minimizes EMI emissions
• Isolates electronics from contamination
• Provides conduction cooling path for electronics
• Airflow is directed directly over processor
heatsinks

All Themis Slice-CT blade servers are inherently rugged,
have a uniform mechanical footprint and a standard rack height
(1RU) and depth (22"). Subracks can be interconnected
together, using external switches, to configure highly scalable
grid computing systems.
Slice-CT Processor Module
Themis’ Slice-CT is based on an industry standard four
socket Opteron motherboard that can use either dual or quad
core processors.  The
motherboard is enclosed in a light alloy clamshell, isolating
the electronics from the environment. The clamshell provides
several benefits:
- Mechanical support to mitigate shock and vibration.
- Forms a Faraday cage around the electronics to
control emissions.
- Protects the electronics from dust and dirt contamination.
- Conduction cooling for the electronics.
- Integrated blowers for a scalable cooling system,
with low acoustic emissions.
Slice-CT I/O Module
 The
module contains three slots for I/O cards. Each slot can accommodate
a PCI Express or a PCI-X card. The I/O module connects to
an individual Slice-CT processor blade via a PCI Express bus,
through the system backplane. The I/O module is 1U high and
blind mate connects into the 4U or the 10.5U subrack. I/O
connector access for the three I/O cards, is at the front
of the module.
Slice-CT Subrack
Slice-CT blades installs directly into either a 4RU or
10.5RU high subrack. The 4RU subrack accommodates 3 Slice-CT
blades or 12 Opteron sockets. The 10.5RU subrack accommodates
9 Slice-CT blades or 36 Opteron sockets.  Each subrack
includes a backplane, N+1 redundant power supplies (PSU’s)
and redundant Gigabit Ethernet or InfiniBand switches.
Slice-CT processing modules communicate with each other
and the outside system via the integrated GigE or InfiniBand
switches. Slice-CT PSU’s are hot-swappable. The Slice-CT
Subrack provides internal cable management, minimizing
total cost of ownership.
The Slice-CT Subrack mounts into a standard 42U rack,
for a total of ten 4RU Slice-CT Subracks, or four 10.5RU
Slice-CT Subracks. Slice-CT only occupies 17” rack
depth, ideal for shallow rack applications such as telco
wiring closets.
Slice-CT Switch Fabrics
Slice-CT processor Blades are interconnected by redundant
switch fabrics running through the subrack backplane. Redundant
InfiniBand and redundant Gigabit Ethernet fabrics are available
in a Slice-CT system. The fabrics are implemented in a removable
switch module that plugs into a Slice-CT subrack. The switch
module includes both InfiniBand and Gigabit Ethernet switches.
External InfiniBand and GigE ports allow a subrack to be connected
to other subracks or integrated into a larger system.
Slice-CT Management
A Slice-CT system includes a full complement of server management
features, including redundant shelf maintenance controllers.
Each subrack can be accessed remotely for management purposes.
Each processor blade can be monitored for power control, status
information, sensor readings and system event logging.
