vSphere Paravirtual SCSI testing

I hopped on the wagon to test vSphere with the new Paravirtual SCSI driver.

I used I/O meter, with 10GB test files, one per drive. 32K 100% read.

I did a comparison of 1 LSI VDMK drive, vs 1 paravirtual VMDK drive, vs 1 RDM, vs 1 paravirtual RMD.

1disk_lsi_vmdk

1disk_paravirtual_vmdk

1disk_rdm

1disk_paravirtual_rdm

And then I did a comparison of 3 LSI VDMK drive, vs 3 paravirtual VMDK drive, vs 3 RDM, vs 3 paravirtual RMD.
