Сервер Dell PowerEdge Жесткие диски Замены в горячем режиме BitLocker

It should work, yes. Hardware RAID is listed as supported in the Technet documentation on BitLocker. And here's a quote from a 2006 MS Bitlocker Team chat session.

Jamie [MS] (Expert):

Q: How does BitLocker work with hot swapping RAID drives?

A: BitLocker works at the Logical volume level (technically, above the volume management driver). As long as the hardware presents a logical volume to the OS that is handled by volume management, BitLocker should have no problems with it. Although at this time we have not tested hot swapping RAID drives, I dont forsee an issue with this.

Looks like you're good.
