thorough and consistent with the #793 lab: annotation names, metric rename with the legacyMetrics fallback, upgrade ordering and the mig manager boundary all line up. frozen versioned docs untouched, correct. the scoped zh notes are a pragmatic interim, please open a follow up issue for the full zh retranslation so the v2.9 body text does not linger on next.

The snapshot was cut before the v2.10 feature documentation PRs (Project-HAMi#794, Project-HAMi#734, Project-HAMi#759, Project-HAMi#775) merged, so it described v2.9 behavior for flagship features. Keep only the changelog and the homepage release badge for now; re-cut the snapshot once those PRs land. Signed-off-by: Jimmy Song <jimmy@dynamia.ai>

this banner says everything below is v2.9 and does not apply, but line 69 in the same file now points at the v2.10.0 chart. a reader following the body will still configure knownMigGeometries. is a banner enough here?
There was a problem hiding this comment.
Fair point. In bb8e3aa I added a scoped v2.10 note directly above the knownMigGeometries example that says it is the v2.9 format, points at the v2.10.0 configmap linked on line 69 for the current migProfileAllowlist shape, and links the English migration steps. The full zh rewrite is tracked in #836 and sequenced after this PR so it starts from the final English text.

#815 also edits this file, in the version of it that this pr deletes. one of the two will need a rebase. which should land first?
| - v2.10 使用预留优先模型。`migProfileAllowlist` 只定义集群允许使用的配置文件名称；显存、算力、切片数量及合法 placement 由每个节点通过 NVML 发现，并以 `migProfiles` 发布给调度器。当前 Chart 还包含 **RTX PRO 6000 Blackwell Server Edition** 的 `1g.24gb`、`2g.48gb` 和 `4g.96gb`。 | ||
| - 调度器在绑定 Pod 前预留物理 GPU、profile 和 placement，并写入内部注解 `hami.io/vgpu-mig-allocations`。device plugin 在 `Allocate` 阶段按该预留创建每个 Pod 的 GI/CI，随后补充 MIG UUID、GI ID 和 CI ID；用户不得自行创建或修改此注解。 | ||
| - Pod 删除、成功或失败后，device plugin 会回收该 Pod 对应的 CI/GI。重启时，具有完整运行时身份的活动实例会经 NVML 校验后被接管；旧模板/slot 标识无法安全接管。 | ||
| - 当前 MIG 指标为 `hami_node_gpu_mig_instance_info`，包含 profile、placement、MIG UUID、GI ID 和 CI ID。仅当 `legacyMetrics: true` 时才额外输出旧指标 `nodeGPUMigInstance`，Chart 默认值为 `false`。 |

the zh page now names hami_node_gpu_mig_instance_info while its own metrics block further down still prints nodeGPUMigInstance. should that block move behind the legacyMetrics note too?

Done in bb8e3aa. The zh monitoring section now leads with hami_node_gpu_mig_instance_info and its labels, and the nodeGPUMigInstance sample sits behind a note saying it is only emitted with legacyMetrics: true (Chart default false).

checked this against pkg/device/nvidia/mig_allocations.go: the annotation key, all eight field names and their order match, and the three omitempty pointers line up with the runtime identity being absent at first. same for MigProfile and the scheduler metric. nothing to change here.

Thanks for checking it against the source.

| GPU Operator may continue to provide the NVIDIA driver, Container Toolkit, DCGM, and other infrastructure. Before HAMi assumes mutation ownership, stop MIG Manager reconciliation and ensure a controller cannot recreate it or reapply `nvidia.com/mig.config`. Deleting one MIG Manager Pod without changing its controller policy does not establish that boundary. | ||

doc links in this repo carry the .md extension. does this one still resolve from the developers folder?
There was a problem hiding this comment.
Fixed in bb8e3aa: both relative doc links this PR introduced now carry the .md extension, this one and the ../monitoring/device-allocation link in the user guide.
- Put the zh knownMigGeometries example and the legacy nodeGPUMigInstance metrics sample behind explicit v2.10 notes, so a reader following the body knows both describe v2.9 and where the current format lives. - Add the .md extension to the two relative doc links this change introduced, matching the repo convention.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Mirror the applicable v2.10 guidance in this Chinese page before merge.
This note sends Chinese readers to the English migration section and leaves the remaining configuration procedure centered on the legacy knownMigGeometries workflow. The English update covers capability discovery, reservations, lifecycle, ownership, and migration. Add the applicable Chinese sections here, or remove and clearly scope the legacy procedure so it cannot be followed as current v2.10 guidance. Tracking issue #836 does not satisfy the repository parity rule for this change.
As per coding guidelines, applicable English documentation changes must be mirrored in the Chinese current documentation.

this points at /docs/ which serves v2.9.0, so after merge the v2.10 sample sits at /docs/next/ and this link lands on the old page.

What type of PR is this?
/kind documentation
What this PR does / why we need it:
The current website still describes the v2.9
knownMigGeometriesand whole-GPU template workflow. HAMi #2378 replaced that with a reservation-first Dynamic MIG implementation for v2.10.This updates the Next documentation to cover:
migProfileAllowlistand NVML-discovered capacity and placements;hami.io/vgpu-mig-allocations;hami_node_gpu_mig_instance_infometric;The workload example now explains profile selection and placement-dependent Pending behavior. The Chinese current pages include a scoped v2.10 behavior note so readers are not misled by the retained v2.9 translation.
Frozen versioned documentation is unchanged.

Testing:
Both English and Chinese builds pass.
AI assistance disclosure:
AI assistance was used to compare the website pages with the current HAMi architecture and migration documents. I reviewed the resulting contracts, examples, links, and rendered build.
