Amps and Vprocs

[baycolor]

Can someone explain exactly what an AMP and a VPROC are?

Is an AMP hardware or software (is an AMP a disk)?

VPROC stands for virtual processor. Correct? So it is a software version of a processor?

Thanks in advance.

AMPs are a type of VPROC, the other being a PE (parsing engine). VPROCs, AMPs and PEs are all virtual, created by software. PE do the query parsing and session control, AMP perform the query steps.
