Press Release
New World Record Set for TCP Disk-to-Disk Bulk Transfer
Kirkland, WA; -
December 10, 2002. YottaYotta (www.yottayotta.com), the Yottabyte NetStorageTM
Company, today announced a new world record for TCP disk-to-disk data transfer
using the company's NetStorager® System. The bulk data transfer
used a Storage Wide Area Network architecture consisting of conventional fibre
channel over TCP/IP encapsulation. The record-breaking demonstration transferred
5 terabytes of data between Chicago, Illinois to Vancouver, British Columbia and
Ottawa, Ontario, at a sustained average throughput of 11.1 gigabits per second.
Peak throughput exceeded 11.6 gigabits per second. These results are more than
15-times faster than previous records for TCP transfer from disk-to-disk. The
average utilization of available bandwidth was in excess of 93%, with available
WAN bandwidth being the primary constraint on transmission. This record was achieved
in conjunction with seven key partners: CANARIE, WestGrid, BCNET, StarLight, Netera
Alliance, The Logistical Computing and Internetworking Laboratory at the University
of Tennessee and The Physics Department at Carleton University.
"This
is a new world record, equivalent to transferring all printed collections from
the Library of Congress within two hours time," said Wayne Karpoff, vice
president and CTO for YottaYotta. "It's proof that YottaYotta uniquely
enables the global sharing of massive amounts of information in ways that today's
business applications and recovery schemes require. Additionally, emerging GRID
computing schemas will demand the type of data accessibility and transfer that
YottaYotta is delivering today."
Loop-back experiments were
also conducted where data was transmitted "round-trip" from Vancouver
to Chicago and then back to Vancouver again, a distance of approximately 6,214
miles or 10,000 kilometers. YottaYotta's NetStorager System provides extra
reliability and error correction services in addition to those provided by conventional
TCP. The end result is a far greater assurance of data integrity than can be achieved
with TCP alone.
YottaYotta's achievement
is unique in several ways.
-
YottaYotta
has chosen to employ TCP transmission techniques to ensure that the target receives
every single packet sent. Other transmission techniques, such as UDP, provide
no such guarantee.
-
Data was
both read and written onto physical media at both locations.
-
The NetStorager
System demonstrated 93% sustained utilization of bi-directional bandwidth.
-
The total
throughput for this trial was limited only by the available bandwidth on the test
network, 12 gigabits per second.
YottaYotta provided the
NetStorager System, the high-performance storage wide area network solution, and
the overall project management for the collaborative test. CANARIE, BCNET, and
StarLight contributed optical network infrastructure to the project. WestGrid,
Netera Alliance, the Logistical Computing and Internetworking Laboratory at the
University of Tennessee and the Department of Physics at Carleton University supported
the project with WAN networking expertise and assisted in securing network infrastructure.
About YottaYotta
YottaYotta's NetStorager®
System, the next generation storage solution, converges storage and communications
technologies to enable globally networked, coherent storage. The YottaYotta distributed
system architecture delivers continuous information access, while providing unprecedented
levels of data protection. Operated and managed as a single entity, the NetStorager
System improves operational costs and maximizes resource utilization through sharable
infrastructure. YottaYotta's business solution enables the creation of differentiated
value added services that can be managed, delivered and tracked on a subscriber
basis. Founded in January 2000,YottaYottaÒ is privately funded with
offices in Kirkland, WA; Edmonton, AB; and Boulder, CO.
