I have been out of the Remedy/ARS game for about a year now so I won't speak directly to that but I have been active in virtualization (VMware specifically) so I will comment on that aspect of the question. As long as the back-end storage is configured to support sufficient I/O (i.e. sufficient number of drives in the RAID group) I don't see why a virtualized solution would run into any issues. I know with VMware you can "reserve" server CPU/RAM resources for a given VM so there should not be any issues there either. Will you take a performance hit compared to a dedicated physical box? Perhaps, but if the implementation is sized and configured properly I doubt it would be noticeable. If you've got the funds to blow, putting the DB storage on its own dedicated 5-6 SSD disk fibre-channel or iSCSI storage array should provide plenty of disk I/O and the host server can handle CPU/Mem resourcing. Viability of virtualization for an application like this all comes down to knowing the size of your organization and being able to model the server load. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of LJ LongWing Sent: Friday, July 30, 2010 1:39 PM To: [email protected] Subject: [AKO Warning - Message fails DKIM verification] Re: MSSQL Virtualization? Drew, I can't talk directly regarding the problems BMC was talking about....but just from my own understanding, SQL Server is a very 'heavy' application...it requires lots of RAM and lots of CPU, typically virtualization would make an OS share those resources, which isn't 'best' for this type of application...any time you want something from a DB, you want it as fast as possible....won't be as good in virtual as it would with Physical... -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Drew Shuller Sent: Friday, July 30, 2010 10:59 AM To: [email protected] Subject: MSSQL Virtualization? Hello all, While helping use architect a new Remedy system, BMC suggested to NOT virtualize the MSSQL server, without giving any reasons except that there were "problems." Could I get some insight please? I would like to virtualize AR Server 7.1 and eventually 7.6 ITSM on a virtualized MSSQL server. What issues should I expect? Thank you in advance.
