Case Study:
Move of Server Room Infrastructure for International
Information Technology Corporation
Background:
An international information technology corporation
wanted to consolidate over one hundred technical staff
into a new building. The company had two existing offices,
both with server rooms, housing thirty-five servers,
and associated devices such as disk arrays, tape drives,
monitors, consoles, and networking equipment. Most of
the equipment was not housed in server racks.
Requirement:
Arrange the move of all necessary equipment over a weekend
and ensure minimum business hours downtime. Consolidate
the infrastructure into a racked environment to ensure
minimum floor space wasted in new data centre. Ensure the
new server room racks and accessories are in a position
to accommodate future growth.
Solution:
The environment was documented in two spreadsheets,
one containing all servers and their associated accessories,
the other containing all network equipment and associated
network links. All equipment in the server rooms was
labelled with the server or device hostname, or the hostname
of the server or device to which they were attached.
The
amount of infrastructure that would need to be moved
or provided in the new premises was reduced by making
better use of existing resources. Network audits determined
that more switch ports, and therefore switches, were
provided than necessary. Audits of servers determined
duplication of services and allowed for server consolidation
and retirement.
A Visio plan was drawn up of the future
racked environment with all devices that would be relocated.
This plan was
used to help put together a comprehensive parts list
and subsequent order of six racks, Power Distribution
Units (PDUs), Internet Protocol Keyboard Video Mouse
(IPKVM) and accessories, rack monitor, and various
server racking parts.
When the new equipment arrived work that
was able to be carried out in advance of the move was
completed.
Fifteen consoles and monitors and a six port KVM, used
by mixture of Windows and UNIX servers, were retired
and replaced by a single keyboard, monitor and mouse
with IPKVM that was capable of supporting one hundred
and forty four servers. HP-UX servers were configured
for use with IP network consoles which had not been
previously utilised. All racks and accessories were set
up in the
new data centre.
Plans were completed detailing the order,
timing, and instructions for server shutdowns and
cutover of network
links, including details of any staff that needed
to be advised or contacted at the time. A plan also detailed
priority of servers’ start-up order, and the
testing of them once running, to confirm normal functioning.
A moving company was organised, and supervised, in
bubble-wrapping, externally labelling, and moving
all server room equipment
to vacant floor space allocated to each rack’s
equipment in the new data centre. A team of six technical
staff from within the company were organised to assist
during the move weekend.
Servers were shut down from
4pm on Friday afternoon. The movers started around
the same time and had all
equipment placed in the data centre by midnight.
The technical
team started work at 7am on Saturday and had all
the servers racked and cabled into the six racks
by 7pm.
On Sunday morning testing was carried out and the
move was officially complete by lunchtime.
