Adoption of kernel UEK or UEK2

I'm curious to hear stories about Kernel UEK, either one or two and its adoption in the industry. Given that Red Hat seems to be consistently producing great financial results one wonders about the Oracle Linux footprint in the real world.

For me OL 6.2 and 6.3 have been a blessing: free security updates, new kernels with interesting features etc. However when it comes to large organisations and standardisation, the terms change. To be even remotely able to suggest UEK as a kernel to be rolled out to potentially thousands of systems vendor support is crucial. I wonder if HP, Dell and others actively certify UEK. Moving up the stack it requires certification from the SAN vendors for their multipathing drivers, their storage management software etc. Once you reach the OS stack it's simple because you can get support from Oracle.

If those of you on Linux, if you wouldn't mind, let me know your experience with UEK, why it has been adopted or not, and how it went.

Thanks in advance!
