Q: Is this drive supported in my UCS chassis?
A: If your UCS platform supports 3.5-inch 12G SAS nearline HDDs, it should be compatible. Confirm on the HCL.

Q: What sector format does it use?
A: Sector size can vary by sub-SKU; verify whether your environment requires 4Kn or 512e.

Q: Is a caddy required?
A: Yes, a UCS-compatible carrier is typically needed if not already present.

Q: Can I mix with smaller capacities in the same array?
