Hello,
I cannot make an accurate statement, because the actual
efficiency of the system complex depends heavily on the usage scenario. However
the devices should be able to handle most scenarios at a greater cost and power
efficiency than a lot of systems in use today.
One of the storage units should roughly have a maximum
power draw of 600 watts. 24 hard drives (10.7W at peak each) + ~300W for the other
electronics.
The virtualization units should draw a maximum of ~800
watts, each. That totals to about 7600 watts. Given the cooling and the network
switch also draws power, it is safe to say that the rack draws around 8000 watts
at a power supply efficiency of 87-90%.
Given that most power supplies, only have an efficiency
of 67-79%, the system is highly power efficient.
The next thing is the use of virtual machines, rather than
using real ones. The use of a virtual machine over a real one has the advantage
of sharing unused resources of the host machine and a higher workload for the host.
Whilst higher workload means a higher current draw from the power outlet, there
are two ways to save:
1. Savings in hardware costs and space requirements.
2. Savings in power overhead through the use of a single
instead of multiple power supplies. This reduces the lost energy through power conversion
greatly.
3. Savings in power draw through sharing devices that are
otherwise mostly unused by the system but need to be constantly supplied with power.
Also, the usage of liquid cooling allows a closer placement
of racks in the data center. This means more racks could fit into a larger datacenter.
This is space efficient.
To sum it up: The system could allow 384 redundant virtual
machines, each with 512MB of RAM and 640GB of storage space (they would make great
web servers or servers for video broadcasting, for example). Those systems might
as well draw up to 700 watts from the power outlet, each.
384 * 700W = 268800W
Compared to the low value of 8000W the new system would
use about 3% of the power the old systems would have used. Even less if some storage
units are turned off, because there is currently no demand.
The hardware costs should be lower as well, but if they
aren’t the power savings should justify a slight price increase. I don’t have access
to commercial pricing quotes.

Hi Dorian,
In reviewing your
submission, the judges were wondering if you could please quantify the power and
cost savings of your proposal and provide an explanation for how you arrived at
those numbers. Pending your response, we hope to finalize our selections and notify
the winners next week. Thanks, let me know if you have any questions.
Best,
Heather

Hello,
This is a written proposal for the efficient use of a 45U rack in a small business
datacenter with a standard room height of 2.30m to 2.35m.
This design consists of custom built units, that do not outline the use of vertical
space or the type of rack equipment used. Any 45U or higher rack will suffice.
All units must use 80+ Gold certified power supplies to achieve maximum usage of
drawn current. The units will use liquid cooling combined with silent air cooling
for the components where water blocks cannot be attached. The liquid coolant will
be either thermoelectrically cooled in dry room environments or employ radiated
active cooling to enable most efficient use of volatile storage performance, which
may degrade greatly through loud noises or vibration.
The rack will be filled with a 1U 10GBit network switch at the top, two 1U virtualization
units, 10 storage units and a cooling unit at the bottom. Components outlined as
follows:
High performance virtualization units (each):
1x 1U server chassis with two 2.5” hot-swap SATA drive bays
1x Intel® Server Board S5520UR
2x Intel® Xeon W5580
12x 8GB DDR3-1333 ECC registered memory module
2x Intel® X25-E Extreme 32GB SATA Solid-State Drive
1x Intel® 10 Gigabit XF SR Dual Port
Will run a version of Windows Server 2008 with Hyper-V or VMWare Virtual Server
to enable the use of scalable, power efficient virtual servers to provide services
to the end user. The SSDs will run in RAID1 to provide redundancy and serve as storage
for the host operating system, and error dump files. Each virtualization unit will
enable the use of up to 192 virtual servers running Windows Server 2008 Server Core
or a Linux operating system. This can save the power costs of up to 370 hardware
units that would need to be used otherwise.
Storage units (each):
1x 4U 24 hot-swap SATA drive bay rackmount chassis
1x Intel® Server Board S5500WB
3x 1GB DDR3-800 ECC registered memory module
1x Intel® RAID Controller SRCSASJV
24x 2TB 7200RPM SATA hard drive
1x Intel® 10 Gigabit XF SR
Will run a version of Windows Storage Server 2008 or any other type of iSCSI target
enabled operating system to provide large amounts of storage to the end user for
RESTful resources or the virtualization units in the same rack. The drives will
be combined to RAID6 arrays which will be striped with RAID0 to build a large RAID60
storage array. Optionally the iSCSI targets will be assigned in partial blocks of
their total storage, which will be striped again. The remaining storage on a storage
unit will then be used to provide the end user with RESTful services. Those services
aren’t very hardware demanding and can be run on the storage units to increase efficiency.
The storage units will use low power mainboard and CPU components as well as the
amount of memory which provides the best power to performance ratio. A storage unit
will not be demanding in CPU power and this will enable the low power CPU to turn
off additional cores and further lower the clock speed using Enhanced Intel® Speed
Step technology to keep the power draw for those units at a minimum to allow the
power supplies to work efficiently. Storage units can be turned off when they are
not needed and turned on, when the storage demand increases.
With up to 384 virtual servers (512MB RAM, demand switched CPU clock cycles, and
an average storage of 640GB) one single rack can replace a small datacenter, greatly
reduce power costs and the costs for sound proofing in urban areas. The power draw
for a single rack can be projected to range between 5000 and 10000 watts, when all
units are powered on and on average to full workload. Additionally to saving power
the equipment costs may be reduced as well, which means again less harm for the
environment with contaminates. It is recommended to run two racks combined for additional
redundancy and the system is highly scalable to be suited for enterprise usage as
well.
