FAQs

Q: Will this work alongside existing 512e drives?
A: You can mix in the enclosure if the controller supports both formats, but do not mix 4Kn and 512e within the same virtual drive/RAID group.

Q: Is any firmware customization required?
A: Use the drive with the appropriate UCS firmware baseline supported by your platform. Check release notes/HCL for exact compatibility.

Q: Is a caddy included?
A: No, the UCS drive tray is not included unless explicitly listed.

Q: Does this support dual-path failover?
A: Yes. The 12G SAS dual-port interface supports multipath configurations when the system is configured accordingly.
