When we need CAS in SCCM1012

I was working on  SCCM2012  design for a small environment and wanted to figure out if I need to incorporate CAS ( Central Administration Site ) in the design. Initially I was assuming that CAS will provide HA in the environment, but I was wrong . CAS is only required when we want to manage 100K+ clients  and when we have multiple primary sites. For a relatively small environment,  people are recommending to go with stand alone primary site.

Here are some links for a good reference on CAS:

How to Remove Plug-ins from vCenter

Some back ground about the issue :

I removed a plugin from Add/remove Programs of vCenter server but still it was showing up in the vSphere client. I was able to  enable/disable it but could not remove it from the list of available plug-ins in Plug-in Manager. This becomes an issue specially when you don’t want people ( vmware admins and non-admins)  to see any such plugin when they  connect to vCenter server from the vSphere client.

To resolve the issue I followed this VMware KB article, which worked like a charm:

Creating CentOS template for vSphere ESX

I came across of online resources for creating CentOS template for vShphere/ESS, keeping here for self notes:

mentioned on this blog (http://ninet.org/2012/09/deploy-centos-6-from-vmware-template/) - Before you convert the VM to a template.

rm /etc/udev/rules.d/70-persistent-net.rules

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

(This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth)

I came across this link on how to create a Server 2012 template for VMware workstation, which can be also helpful in case we have vSphere and vCenter:

While running sysprep  you might see this error “A fatal error occurred while trying to sysprep the machine” .

This is a know issue and Microsoft has released a Hotfix for it.
