Scope
The POC will include
• Installation and configuration ofa maximum ofthree XenServer hosts
• Setup of local & shared storage repository(Does notinclude SAN / NAS configuration)
• Setup basic network connectivity using the hostnetwork (Maximum of six server network card)
• Installation ofXenCenter on an XP or Vista workstation
• Create a new Windows Server 2003/2008 and a XP/Vista VM
• Import/P2V a known good Windows 2003 Server VM onto the XenServer
• Test network connectivity to hostnetwork
• Ensure start-up,shutdown,suspend and rebootoperations ofthe VM
• High availability aspects ofXenServer
• This includes the XenMotion or VM automatic restartfunctions
• Setup of multipath and/or network card bonding
• Conference call or online GoToMeeting session prior to the site visit to discuss the POC to ensure that
prerequisites are metand to further discuss anyspecial arrangements Itis also critical to get an idea of the
success criteria ofthe POC from a customer perspective.
• Mutual agreementofsuccess criteria for the POC.
• An hour set aside (on site) for discussions regarding the completed POC and to look at how this can be
moved into a production environment This will also include a time where any questions regarding anyother
aspects ofthe POC system can be asked
The POC will not include
Setup of the following
9. Page 9 of 18
• Setup or configuration ofexternal storage systems such as SAN or NAS technologies,(see below for further
details)
• Setup or configuration ofthe following
• Networking hardware such as routers or switches
Any software applications (such as SQL,Exchange, and SAP) other than those stated as part of the XenServer
system.
Responsibilities
Customer/Citrix Systems/Citrix Partner Responsibilities:
Staffing Requirements
On-site Requirements
Additional Requirements
It is necessaryto be accompanied byauthorised personnel thatcan assistwith anything that is needed to
complete the POC. They should be fully familiar with the testing environmentand available throughoutthe
implementation ofthe POC
For a POC, any integration with existing production services is discouraged.If any componentof the POC is
to be integrated with an existing production system (e.g.DHCP server changes,Active Directory integration,
XenApp farm inclusion etc.) a legal disclaimer will need to be signed by the customer prior to the POC
engagement.
An elementofeducation will be provided during the building ofthe POC if desired which can be extremely
useful to continue the POC into production butthis is not to be confused with structured training that can be
obtained though Citrix authorised training partners which can be obtained atany time.
Valid application software and operating system licenses will be provided by the customer for the duration of
the POC.
The following points should all have been agreed,completed or provided before the Engineer be dispatched to site
All prerequisites listed in the following section are metin full
A conference call or meeting has occurred that has allowed the success criteria to be agreed
Make, model number and specification ofserver hardware and shared storage to be used
What is the workload being virtualised i.e.Windows Server 2003,XenApp and MS Office 2007,SAP R/3 or
Linux, etc
Virtual Machines,(VMs) will be built via whatprocess i.e.standard install,scripted installation,PXE
deploymentsolution,P2Vor CD Image,etc
Please note that 30-day evaluation licenses will be provided along with all XenServer skills. However any
workload specific skills such MS Exchange, SQL Server, SAP and even Citrix XenApp may need to be
provided by the CSA partner or the end-user to ensure a successful POC
Mutually agreed date set for the work to be carried out
Remote facilities to the systems thatare being worked on as well as access to the consoles ofthese
systems
Completion ofthe Citrix Systems demonstration agreement.
Failure to comply with any of these prerequisites will resultin the engineer leaving site and not returning until they are
metin full.
The POC is focused on proving the basic conceptof a XenServer system.Anything further may involve further
consultancyand is likely to be chargeable. A full working day starting is normallydeemed to be sufficienttime for the
POC, however if Platinum Edition is being evaluated as partof the POC a second daymay be required. Any
additional time required maybe chargeable.
10. Page 10 of 18
Supportof the POC will be on a bestendeavors basis bythe engineer that installed the system plus anyother
supportarrangements setup prior to the POC.
It is in the interestof both Citrix and the customer to have a successful POC but this relies on preparation and a
mutuallyagreed time scale and desire to work together If this is possible then the POC should occur in a timely and
costeffective manner and its objectives be metin full.
