We are installing HP DL380 Gen9 servers with HP Smart Array P440ar contollers and SED drives that conform to the TCG Opal v2.0 standard, compatible with the Microsoft eDrive IEEE 1667 protocol.

We plan to use Server 2012 BitLocker to secure data at rest. According to BitLocker literature, the 2012 implementation uses SED drive hardware to accelerate drive encryption and also that BitLocker works with hardware RAID arrays. I can find no information that indicates whether BitLocker can use [take advantage of] SED hardware to accelerate encryption on drives connected to an array controller configured in RAID [10] or not.

Can BitLocker use SED hardware to accelerate encryption on drives connected to an array controller configured in RAID [10]?

No it can't. Only with single drives - each drive has a single key. But feel free to try, setup a RAID, BL will not allow the option to use hw encryption.
