BL460 Gen8 drivers

Hi,

I have RHEL 6 update 2 installed on a bl460c Gen8 server. I have applied latest security updates , and my kernel version is changed from 2.6.32-220 to 2.6.32-220.46. I would like to know what are latest drivers for the bellow listed devices:

1. Emulex 554FLB adapter
2. HP Smart Array P220i

I found that drivers available for RHEL 6 update 2 are prety old (no newer version for this release) and they are build for initial kernel version 2.6.32-220. Please advice what drivers should I use.

Thanks
