Topic 1, Assessing the Current EnvironmentExecutive SummaryProject OverviewCGE is
a global, diversified, upstream (exploration and production) oil and gas company
headquartered in North America. CGE's three main operating areas are North America,
Europe, and Southeast Asia. CGE also has a portfolio of international exploration
CGE began in North America as a small, upstream oil and gas company. Through acquisitions,
CGE grew quickly and acquired companies global y. This led to a decentralized IT model, both
from systems and personnel perspectives.
CGE currently utilizes several Citrix technologies to provide application virtualization to a global
end-user base spread across several continents. Its current IT model for application
virtualization is based on regional locations; each region hosts its own Citrix environment to
support its local end-user base. CGE is moving toward a global IT model in which the entire
application and desktop virtualization environment wil be hosted in three data centers, each
with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some
end-user groups to alleviate past issues with applications and performance. In addition, an
Internet upgrade project is underway to eliminate slow connections at all sites. This wil improve
latency and bandwidth issues throughout the environments.
CGE engaged Citrix Consulting to determine whether best practices are being followed in its
existing Citrix environments; to provide a design document for a new, consolidated Citrix
environment; and to point out risks that should be resolved before moving to this new
environment. This deliverable represents the output of the requirements gathering phase and
wil be used as an input during the architectural design phase of this engagement.
Through interactive meetings, Citrix Consulting obtained information regarding CGE's existing
Citrix XenApp environments and strategic goals. By reviewing this information, CGE can
understand and methodically address those areas that represent the most profound risks,
improve various facets of its current environments, and prepare for the future design phase of a
Project GoalsDuring the course of the project, CGE and Citrix Consulting identified a number of
project goals. The following summarizes these goals:
? Perform a detailed assessment of the Citrix components supporting the existing Citrix
environments, which include XenApp 6.x, XenServer, and NetScaler Gateway.
? Review relevant peripheral components that support the existing Citrix environments (for
example, Active Directory, storage, SQL, networking) to determine if each can support current
production workloads and a new Citrix environment.
? Identify operational and environmental improvements to better account for the environments'
OverviewCGE has locations spread across three primary regions--North America, Europe, and
Southeast Asia--with its primary headquarters located in Houston. Sub regions exist within each
region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee,
Houston wil be the primary datacenter and London will be the secondary datacenter.
