You will want more RAM and probably more cores; when mid-tier
preloads/prefetches it will put everything we have available to work.
These are production 7.6.04.01 hotfix 1 systems on Windows Server 2003 R2
Enterprise x64 except the db.
Our mid-tier servers are 12 gb RAM with 16 cores. The production mid-tier also
has Kinetic Request so that is two tomcats, plus currently has BOXI and
Analytics which is a couple more. 5.15 gb of RAM are in use right now, with
mid-tier tomcat highest at 1,819,280K peaking to 1,863,584K. Kinetic Tomcat is
612,752K to 714,540K.
SQL 2008 server and AR 7.6.04.01 server are both 24 gb RAM with 16 cores.
The db server usually has 17 gb of RAM in use - the ARSystem db is currently
17 gb in size - SLQ Server max ram is 16384; a second instance is limited to
6144.
The AR Server also has admin mid-tier and flashboards, aremail, another
tomcat for SLM Collector - usually runs with 8.1 gb of RAM in use
ARServer is at 1,800,464K peaking to 3,083,060K, mid-tier tomcat at
1,154,852K peaking to 1,186,00K, AREmail is 641,900K to 725,636K.
All are 64-bit OS and java although only the DB server is 2008 R2 - rest are
2003 R2. Nothing is virtual. CPUs are various flavors of early i7s, so 2 CPUs
with 8 cores each. Dell R610 and R710.
Make darn sure that you set parallelism on SQL Server to half of your cores
(see BSM Performance Tuning).
Stated out with 73 gb drives in RAID 1, RAID5, (another RAID 1 on SQL Server)
and had to move to 146 gb drives to accommodate data files. Today would use
300s. I you are using SAN or something it may not matter ; I like my ARS
dependent on as few external systems as possible - basically network and LDAP.

Subject: Sizing 7.6.4
**
Hi,
We are installing AR Server / Asset Management / CMDB / ADDM / Mid Tier 7.6.4
on SQL 2008:
Currently the specs for AR Server are:
Cores: 4 x 2.0 GHZ+
RAM: 4 GB
Disk: 40 GB
OS: RHEL 5.5 -64 bit
Servers: 2
Mid Tier:
Cores: 4 x 2.0 GHZ+
RAM: 4 GB
Disk: 20 GB
OS: Windows 2008 64 bit
SQL
Cores: 8 x 2.0 GHZ+
RAM: 4 GB
Disk*: 40 GB
OS: Windows 2008
64 bit
Storage is in the SANS. Each server is virtual. The next phase we may
implement Incident Management / Change Management. What is a reasonable size
for RAM and Hardware? I thought 64 Bit should be at least 8G RAM. The users
are saying the documentation says "minimum requirements of 4G RAM." What are
your thoughts in terms of RAM? What would drive the sizing? Are there some
metrics that would help us to better calculate the size?
The documentation stated that it should be 3.0GHZ.
