Installation scope

Check before ordering

Match the full manufacturer model, including its suffix, to the offered label. OEM firmware and carrier requirements need a separate check.
A matching capacity and connector do not establish server compatibility. Check the host support list, controller, backplane, firmware and power budget.
Requires a supported SAS controller and SAS backplane. A SATA-only connection cannot operate this SAS drive.
Verify the active logical sector format and RAID-controller support before adding the drive to an array. Sector conversion, where supported, must be planned separately.
Request SMART data, power-on hours and exact-item photos; agree whether the offered unit is new, used or recertified.
Confirm the security variant, encryption state and key-management compatibility of the exact delivered drive.
Check the documented pin-3 Power Disable behavior against the enclosure power connection.

Use the complete model number for the requested drive. A carrier or OEM spare number is a separate identifier.
