M630-specific H330, H730 and H730P controllers, matched by part number so the rack-server lookalike never bites you.
RAID controllers for the M630 come in a blade-specific form factor, and that is the trap: a PERC with the same model name pulled from a rack server will not fit the blade. The lineup runs from the cacheless H330 for straightforward HBA-style duty to the H730 and H730P, which add battery-backed non-volatile cache for write-heavy arrays, the P carrying the larger cache. Virtual disks generally import when you stay within the same controller family or move upward, but confirm before swapping rather than after. If your blade lives in a VRTX chassis rather than an M1000e, storage may route through the chassis instead, so check that before ordering. Match the Dell part number from the controller label or send the blade's service tag for a free compatibility check.
No. The M630 takes blade-specific controller form factors, and a controller with the same model name from an R630 or similar rack server is a physically different part. Match the blade part number.
Replacing with the same model, or moving up within the same PERC generation, usually lets the new controller import the foreign configuration from the disks. Back up first regardless, and confirm the specific swap with us before pulling hardware.
The H330 is the cacheless entry controller, adequate for HBA-style use and light RAID. The H730 and H730P add battery-backed non-volatile cache that matters for write-heavy RAID 5, 6 and 10 arrays, with the P model carrying the larger cache. Match what failed unless you are deliberately upgrading.
