The first three (Bus logic, LSI Logic Parallell and Serial) are emulated controllers
These exist in real hardware and most operating systems have a builtin driver for these,
which makes them able to detect the controller and disk at installation and later use for accessing the drives.
 
The Paravirtualized PVSCSI is not a "real" controller, but a special VMware made SCSI controller, 
with lower overhead and increase disk IO performance and throughput
The operating systems does not have a builtin driver for that and need a driver supplied before the controller could be used. 
This is installed together with VMware tools.
 
Only a few of the most common guest operating systems have a PVSCSI driver.

구분 (윈도 기준)
BusLogic Parallel = Windows NT/2000
LSI Logic Parallel = Windows 2003
LSI Logic SAS      = Windows 2008
Use for second scsi controller for data disk with high IO: VMware Paravirtual

최종정리
 
5.x의 경우 RHEL 5 이외에는 반가상화를 쓰면 무난한 것 같습니다.

* 주의사항
PVSCSI adapters are not suited for DAS environments.
