Industry term for vCenter server appliance is vCSA. VCSA is pre-configured Linux appliance based on SUSE Linux enterprise version 11. A default credentials for VCSA is username/Password: root/vmware.
Good Things
You can deploy vCenter on ESX4.x/ESXi4.x or later
Installation is easy, needs no additional software e.g. AV
License for Windows OS and VC Database is saved
Tuning of OS is not needed
Other agents which run on OS it’s CAPEX and OPEX is saved
Can be easily integrated with AD
vSphere web client is built into it, so no separate installation needed
Te syslog collector is bundled with the vCenter Server Appliance (VCSA) and requires no extra setup
Bad Things
IBM DB2 and SQL Server are not supported for VCSA
Linked mode not supported
VSA not supported
IPv6 not supported
vCenter heartbeat not supported
No plug-in support
Embedded database is limited to small inventory
Software and Hardware Requirements
|
Platform |
vSphere4.x or later |
|
Hosts |
ESX4.x/ESXi4.x or later |
|
Disk Space |
Minimum 7 GB and maximum 80 GB |
|
Memory |
8 GB (not sure why this is default memory picked when it is deployed) |
|
CPU |
2 vCPU |
Network is automatically selected and it is VMXNET3. SCSI controller is LSI logic. All these options are automatically selected. VM hardware is base d on version 7.0 to make it compatible with vSphere 4.x
Memory requirements
4 GB
is the minimum needed for 10 hosts & 100 VM’s –very small inventory
8 GB
is the minimum needed for 100 hosts & 1000 VM’s –small inventory
13 GB
is the minimum needed for 400 hosts & 4,000 VM’s –medium inventory
17 GB
for anything above than 400 hosts and 4,000 VM’s –large inventory
Up to small inventory you can use embedded database but anything other than i.e. medium & large inventory you have only one choice which is Oracle.
VCSA can be configured using web interface which runs as 5480 port

migration FROM CLASSIC ESX4.0 TO ESXI5.0 SCREEN CAST-post 03
Screen cast of How classic ESX was upgraded to ESXi5.0
1) Server was booted with ISO, Selected to boot from ISO
2) INSTALLER PROCEEDS, PRESS ENTER TO CONTINUE
3) ACCEPT EULA, BY PRESSING F11
4) INSTALLER SMARTLY DETECTS PREVIOUS INSTALLATION GIVING YOU OPTION TO INSTALL OR UPGRADE
5) SELECT OPTION FIRST AS WE WANT TO MIGRATE AND NOT INSTALL
6) AS IN MY CASE I’M INSTALLING ESXI5.0 ON VM, BELOW WARNING CAN BE IGNORED
7) LAST STEP – CONFIRM YOU WISH TO MIGRATE
