Technical Specifications

FAQs

Q: Is this drive compatible with my Cisco UCS or HyperFlex node?
A: If your system supports 3.5-inch 12Gb/s SAS drives with 4Kn format, it is generally compatible. Check your server/HX node HCL for 4Kn support and required carriers.

Q: Does this include a drive caddy/carrier?
A: Unless specifically stated, drives are supplied as bare drives. Reuse your existing carrier or procure the correct carrier for your chassis.

Q: What is 4Kn and do I need it?
A: 4Kn uses 4096-byte native sectors for improved efficiency and error correction. Your controller/OS must support 4Kn; otherwise choose 512e/512n models.

Q: Can I mix 4Kn and 512e drives in the same array?
A: Mixing sector formats in the same virtual disk is not recommended and often unsupported. Keep arrays uniform for best compatibility and performance.

Q: Is this a self-encrypting drive (SED)?
A: This variant is not specified as SED. If encryption at rest is required, select an SED-designated model.
