Subsea 7
HPE upgraded all major land-based
operations to Microsoft Skype for Business.
HPE consultants also migrated Subsea 7’s
data from one datacenter to four datacenters
around the world and implemented a highly
available disaster recovery solution.
Implementing a
global solution
The original datacenter is located in Redditch,
England, and HPE designed a solution based
on distributing the call loads worldwide. HPE
designed and built additional datacenters
in Houston, Singapore, and Aberdeen, and
implemented a disaster recovery solution
to ensure continuous operations. This has
not only reduced bandwidth costs, it has
improved the performance of voice calls by
reducing delays.
“We didn’t have a disaster recovery solution
in place and we needed to ensure reliable
failover so we could successfully implement
SIP trunking to carry calls over the Internet
while ensuring performance and reliability,”
states Leport. “HPE established Skype for
Business mediation pools in each datacenter
with an eicient disaster recovery solution.”
The new Singapore, Houston, and Aberdeen
datacenters failover to the original datacenter
in Redditch. In the event of a failure at the
Redditch datacenter, it will failover to the
datacenter in Aberdeen.
“We worked with our service provider to
deploy SIP trunks to all of our land-based
locations worldwide, except for our smallest
oices and locations in countries like Egypt
that do not allow SIP trunking,” says Leport.
“SIP trunking now allows us to consolidate
our voice traic worldwide and dramatically
reduce our calling costs by virtually
eliminating international calling costs by in
eect routing all of our calls as local traic.
We estimate that the company will save more
than 50% in calling costs in our first year.”
HPE implemented Microsoft Skype for
Business at the four datacenters on HPE
ProLiant BL460c Gen9 Server Blades, and
also deployed Skype for Business at Subsea
7 locations on five continents. Among the
locations deployed include: 8 in the UK; 3
in Brazil; 2 each in the U.S., Singapore, and
Australia; and one each in Gabon, Nigeria,
Canada, France, Portugal, and Angola.
Subsea 7 also deployed Microsoft Skype for
Business on all Subsea 7 vessels, providing
them with conferencing, presence, calendar,
and desktop sharing capabilities. “We
consider our vessels ‘floating oices’ and have
provided them with collaboration features,”
explains Leport. “But because they’re at sea
they still rely on satellite calling services to
make voice calls.”
