Subject: Architecture for ARS 7.6.04 ITSM7.6.04 - 32bit vs 64bit OS
**
Hi all:
I have a question about 32bit v. 64bit OS in a 3-tier architecture for ARS
7.6.04 ITSM 7.6.04 (Asset Management only).3
Our current PRD environment is an ARS 7.6.04 SP2 on a Win2003Server 32bit OS
with a SQL Server 2005 DB. DB, Application, and Mid-Tier all on one server for
a small environment with no approximately 50 concurrent users. Our service
ticketing application is 100% custom built.
I have installed a development ennvironment ARS, CMDB, and ITSM (Asset Only)
7.6.04 SP3 on a single Win2008 32 bit server to to learn the ITSM
Administration and Asset Management Admin User functionality - all seems to
be working OK with only a few minor glitches.
We're currently planning a PRD implementation involving a three-tier
architecture with separate for DB (SQL2008 64bit), Application, and Midtier.
Our Server Team is wondering if we can make do with a single Win2012 64-bit OS
for the DB and two Win 2008 32 bit servers for Mid-Tier and Application
functions.
Not being a networking or OS expert, (just a lonely applicaiton admin) my
initial understanding of the differences in the two OS's leads me to believe I
should be making a case for a homogeneous server architecture. I think that
any performance enhancements resluting from movement to a 64-bit OS on the DB
Server would be nullified by the slower performance of a 32bit Mid-Tier server.
And, I would think the larger file and app sizes associated with the CMDB and
the Mid-Tier processing should realize greater processing improvements in a
64bit environment. It may be that in a small environment such as ours, the
differences would not be so great. But I could use some assistance getting my
head around the concepts so I can make the appropriate recommendations.
Any feedback on these considerations?
Regards,
Trez
