Today's focus: The ups and downs of providing dual access into
the data center
By Steve Taylor and Jim Metzler
In our last newsletter, we discussed the plans that IT
organizations have for providing high-speed access into their
data centers. The basis of that newsletter was a discussion we
had with AT&T and Verizon. This week, we will look at the same
topic but this time, based on conversations we had with almost a
dozen IT organizations.
Some of the IT organizations that we talked to distinguished
between a primary or 'Class A' data center and secondary or
'Class B' data center. Virtually all of the IT organizations
stated that they provided dual access into their primary or
Class A data center, but none provided dual access into their
secondary or Class B data centers.
Where possible, the vast majority of IT organizations prefer to
have separate service providers provide access into their data
centers. This is done in part in an attempt to gain true
physical diversity of the access circuits. This is also done to
minimize the risk of a carrier's problems - whether they be
financial or technical - having an adverse affect on the
operations of the organization's data center. Having multiple
carriers also allows an IT organization to put pressure on both
carriers to perform, and to allow the company an easier
migration path away from a poor-performing carrier.
The general feeling expressed by the organizations that we
talked to was that it is easy to pay for diverse access, but it
is somewhat difficult to ensure that the access is truly
diverse. One of the interviewees related the story of a major
airline whose operations center was knocked out of service by a
backhoe a few years ago. The painful piece is that the airline
had paid for diverse routing - the airline did have their access
circuits in separate conduits but the two conduits crossed each
other and that is where the backhoe hit.
Our next newsletter will reflect what IT organizations have to
say about a number of other topics related to providing
high-speed access into their data centers.

IT PROS SHARE THEIR TALES OF MAKING ITIL WORK
Running an enterprise network is challenging. IT organizational
change can be even more so if managers don't balance efforts

Technology Infrastructure Library (ITIL) can help, but they
