Technical Specifications

FAQs

Q: Will this work in my UCS C-Series server?
A: Yes, if your backplane and RAID/HBA controller support 12Gb/s SAS and 4Kn sectors. Consult your server’s HCL and firmware requirements.

Q: Is a carrier/tray included?
A: Typically supplied as a bare drive only. Use the correct UCS carrier for your chassis.

Q: What happens if my OS does not support 4Kn?
A: The drive may not be recognized or usable. Choose a 512e-compatible model or update to a controller/OS supporting 4Kn.

Q: Can I mix SED and non-SED drives?
A: Mixing SED and non-SED in the same array can complicate policy enforcement. Keep encryption capabilities consistent within a pool.

Q: Is this drive helium-filled?
A: Drive internals vary by OEM batch and are not specified; performance and interface remain per listed specs.
