Question
Part 2 after the photo: Once the initial
meeting is conducted Brian can hire the
contractors to renovate the new data
center. During this time Brian will figure out
how to design the network. Brian es Part 2
after the photo: Once the initial meeting is
conducted Brian can hire the contractors to
renovate the new data center. During this
time Brian will figure out how to design the
network. Brian estimates that screening
and hiring a contractor will take about one
week and that the network design will take
about two weeks. The new center requires
a new ventilation system. The
manufacturer's requirements include an
ambient temperature of 67 degrees to keep
all of the data servers running at optimal
speeds. The ventilation system has a lead
time of three weeks. Brian will also need to
order new racks to hold the servers,
switches, and other network devices. The
racks have a two-week delivery time. The
data center supervisor requested that Brian
replace all of the old power supplies and
data cables. Brian will need to order these
as well. Because Brian has a great
relationship with the vendor, they guarantee
that it will take only one week lead time for
the power supplies and the data cables.
Once the new ventilation system and racks
arrive, Brian can begin installing them. It will
take one week to install the ventilation
system and three weeks to install the racks. The renovation of the new data center can
begin as soon as the contractors have been
hired. The contractors tell Brian that
construction will take 20 days. Once the
construction begins and after Brian installs
the ventilation system and racks, the city
inspector must approve the construction of
the raised floor. The city inspector will take
two days to approve the infrastructure.
After the city inspection and after the new
power supplies and cables have arrived,
Brian can install the power supplies and run
the cables. Brian estimates that it will take
five days to install the power supplies and
one week to run all of the data cables.
Before Brian can assign an actual date for
taking the network off line and switching to
the hot remote site, he must get approval
from each of the functional units
("switchover approval). Meetings with each
of the functional units will require one week.
During this time he can initiate a power
check to ensure that each of the racks has
sufficient voltage. This will require only one
day. Upon completion of the power check,
he can take one week to install his test
servers. The test servers will test all of the
primary network functions and act as a
safeguard before the network is taken off
line. The batteries must be charged,
ventilation installed, and test servers up and
running before management can be
assured that the new infrastructure is safe,
which will take two days. Then they will sign off the primary systems check, taking one
day of intense meetings. They will also set
an official date for the network move. Brian
is happy that everything has gone well thus
far and is convinced that the move will go
just as smoothly. Now that an official date is
set, the network will be shut down for a day.
Brian must move all of the network
components to the new data center. Brian
will do the move over the Page 209
weekend-two days-when user traffic is at a
low point. ASSIGNMENT 1. Generate a
priority matrix for AET's system move. 2.
Develop a WBS for Brian's project. Include
duration (days) and predecessors. 3. Using
a project-planning tool, generate a network
diagram for this project. Note: Base your
plan on the following guidelines: eight-hour
days, five-day weeks except for when Brian
moves the network components over a
weekend, no holiday breaks, and March 1,
2010, is the project start date. Ordering
ventilation system, new racks, and power
supplies/cables takes only one actual day
of work. The remaining days are the time
necessary for the vendors to fill and ship
the order to Brian. So use finish-to-start
lags here. Assume that five days after the
start of the renovation of the data center
that the raised floor will be ready for
inspection (a start-to-start lag)
