VCENTER SERVER APPLIANCE
Pro
It’s a VA with all-in-one (included the Web Client)
Simple and smaller (OVA is smaller than ISO)
Faster to deploy (or re-deploy)
Does not require a Windows license
Cons
Not the same features
Not compatible with other components (ie: VUM)

DATABASE EMBEDDED OR NOT?
Actually there are some limits using the
embedded (v)Postgres
In 5.5:
Max 100 hosts or
Max 3000 VMs
What about next version?
External DBMS?
Only Oracle
14/10/2014 vCSA pro and cons
5
LINKED MODE
Windows only (ADAM/AD-LDAP) based
Max 10 vCenters
Max 3.000 hosts
Max 30.000 powered on VMs
Max 50.000 registered VMs
No way with vCSA
What about next version?
Do you really need Linked Mode?
14/10/2014 vCSA pro and cons
6
SCALABILITY CONSIDERATION?
Actually vCSA is a monolithic VM
optional can have an external DBMS
SSO and other platform services are not
sharable
Can be used a Windows Server with vCenter
components
What about next version?
14/10/2014 vCSA pro and cons

VA DEPLOYMENT
Faster than the Windows version
Could be faster?
Could be easiest?
Guided or scripted installation?
What about next version?
14/10/2014 vCSA pro and cons
8
VA PATCHING
The vCSA upgrade process is quite easy
Single point, single updade/upgrade
But could be better?
What about security patches at the OS level?
Multiple repositories or patch levels?
What about next version?
