We have a couple of customers with ARS & ITSM 7.6.04 under VM's, using VMWare VCenter Server and ESX Server. As far as now we haven't faced issues regarding performance due to using VM's. BMC supports VMWare and Hyper-V environments. If your Vm's have all virtual resources (Disk, RAM, CPU) dedicated, there should be no problem in deploying ARS & ITSM. But if you have several VM's using same resource pool, you may need to consult to VM's Admin in order to ensure overall performance. If you're using VMWare Workstation you can "reserve" resources i.e minimum 2 GB and 3600 MHz (sum of frecuency for all processors dedicated to VM) There´s a concept in Virtualization named "Memory Balloon" which refers to "real time assigned Memory" vs. "declared assigned Memory" per VM. Your VM could have 8 GB assigned but meanwhile it's not using all memory assigned, host's memory will be assigned to another VM. In simple words, memory is assigned "On Demand" regardless declared assigned memory. If you have not configured Memory Baloon in a well manner you would face disk pagination which makes VM slower. Here´s a white paper http://www.usenix.org/events/osdi02/tech/full_papers/waldspurger/waldspurger_html/node6.html for understanding Memory Baloon.
Also your VM's admin may consider using Virtual Switchs for grouping all VM's related (ARS, DB, MidTier) in order to ensure network performance. Finally you may want to consult your DBA in order to ensure Database Performance in VM's (assuming your DB is virtualized too) HTH, Alejandro -----Mensaje original----- De: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] En nombre de Brittain, Mark Enviado el: Jueves, 21 de Julio de 2011 10:58 Para: arslist@ARSLIST.ORG Asunto: Re: 7.6.04 sp1 server specs Might want to check the compatibility guide. Different VM's are fully or partially supported. Also Known incompatibilities for virtual environments BMC recommends against running server components of BMC Atrium technologies or BMC Remedy IT Service Management applications within VMware Workstation in a production environment.

I am running a 7.6.04 64bit POC setup on VMs and it is as fast as molasses (with a user load of 1). -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Larry Barnes Sent: Wednesday, July 20, 2011 4:17 PM To: arslist@ARSLIST.ORG Subject: 7.6.04 sp1 server specs I just upgraded my dev server to ITSM 7.6.04 sp1 on a VM box with 2 processors and 8 gb of ram. We are running SQL 2008 on it's own server. This setup is really slow so it concerns me what would happen if I move to a VM for production. I'm curious what others are using that are running a production version of ITSM 7.6.04 on a VM. Are you experiencing any response issues? What type of hardware setup are you using? Thanks for your input.
