Is there no version of the acceleration kit without operations management?
yes, there are two kind of vSphere licenses now.
1. vSphere with operations management.
2. vSphere
The vSphere only lincesne has 3 packages Standard, Enterprise and Enterpriseplus. None of this has VCOPs license included.
In your case, since you dont need Operations Manager you can go for a Standard license and bur six additional CPU license to accomodate all CPUs.
Refer the following white paper for more details on vSphere 5.1 licensing.
