University
of Malaga Hits 2 Terabytes!
Universidad de Málaga (University of Malaga, UMA) is a center
for higher education covering 4 campuses, 19 faculties, 65
undergraduate
courses and postgraduate programs, with some 3800 staff and 40,000
students,
located on the Costa del Sol in southern Spain. Many thanks to
UMA
Administration for permission to publish this data.
UMA is a
significant user of VMS and the largest WASD site, both in terms of
deployment and throughput, that the author is aware of.
The UMA
front-end
system is an ES40 with four EV68A, 833MHz CPUs, 4GB memory, running
OpenVMS 7.3-2 and TCP/IP Services 5.4.
During a 131 day
period, basically March through to June 2007, UMA WASD registered some
two terabytes in network traffic. While UMA has been utilising
WASD since 2003, for various statistic-gathering reasons (WASD updates,
system shutdowns, etc.) this is the first time the (somewhat) magical 2,000,000,000,000 milestone has
become visible (yes - that's two thousand, thousand, million bytes!) This
has been distributed across some 49 million network connections and from that
181 million requests actively processed. As an aside; UMA employs GZIP
encoding and this statistic (not shown) indicates 864GB was compressed to 328GB
meaning an additional 536GB generated during this period never needed to go to
the wire!
The following
three images show selected statistics from WASD's reporting facility.

Note: This final
graph has it's Y axis distorted by a significant peak on June 28th when
results were published online at midnight.
August 2007 Postscript:
UMA reached in excess of 2.5TB after approximately 160 days before before power
grid maintenance in one of it's equipment rooms required a shutdown during the
Summer vacation period.
