RAID 2.0+ Disk Groups: Which Disk Type Is Not Supported?
Short answer
C SATA is the disk type not supported by RAID 2.0+ disk groups, which use SSD, SAS, and NL-SAS drives.
Question
Key Takeaways
This question tests the supported physical disk types for RAID 2.0+ disk groups; the main trap is confusing generic SATA connector compatibility with Huawei's documented enterprise media support.
Huawei RAID 2.0+ disk groups are built from SSD, SAS, and NL-SAS media, so SATA is the unsupported disk type in this H13-611 question.
Common mistake: A candidate may select SSD or NL-SAS because those sound newer or capacity-oriented, but both are explicitly supported; the only unsupported option is SATA (C), even though SATA drives can sometimes attach to SAS controllers.
Expert Analysis
Governing rule: supported media, not connector compatibility. RAID 2.0+ in Huawei storage virtualizes physical disks through a disk domain and forms disk groups from the disks the platform officially supports. The relevant exam doctrine is the OceanStor RAID 2.0+ feature set: disk groups are built from enterprise media types—SSD, SAS, and NL-SAS—while SATA is not listed as a supported disk type for these groups. The question asks for the exception, so option C is the answer.
Applying the rule to the four options. A (SSD) is supported for performance tiers; B (SAS) is a standard enterprise HDD interface; D (NL-SAS) is supported for capacity tiers. C (SATA) is the outlier. The community comment points in the same direction, noting that SATA is not supported and that the usable set is SSD, SAS, and NL-SAS. That comment is useful as corroboration of the product-support boundary, not as a popularity vote.
Why SATA is the trap. SATA drives can often attach physically to SAS controllers, and many generic arrays support SATA. That can tempt a candidate to choose an interface that sounds too old or too new. But H13-611 asks about Huawei RAID 2.0+ disk-group support, not whether a connector is mechanically compatible. The platform's documented media list is what matters; if SATA is absent from that list, it cannot be selected merely because a SAS backplane might accept it.
Elimination check. If A, B, and D are all valid RAID 2.0+ disk-group media, then the only answer that satisfies 'not supported' is C. The question wording does not ask about mixing media in one group, hot-spare rules, or RAID levels; it asks which disk type is excluded from disk groups. Therefore select C.
Exam Strategy
When a question asks which media type is excluded from a RAID 2.0+ disk domain, eliminate options by Huawei's supported enterprise drive set rather than by generic SATA compatibility. Remember that SATA can attach to SAS controllers in general, but Huawei's RAID 2.0+ disk-group design lists SAS, NL-SAS, and SSD. If the exam offers SATA as the outlier, treat it as the exclusion unless the stem explicitly mentions compatibility mode or third-party media.
