大家好，

我在Nutanix的支持下为此提供了一个案例，但是，当我在等待时...

我想知道是否有人可以解释为什么在包含12hdds和6SSD（3节点块）的块中，仅显示SSDS的磁盘统计信息，而列表中HDD的值没有值（所有指标均为0）。

\nThe other case is when the overall tier utilization breaches a specific threshold [curator_tier_usage_ilm_threshold_percent (Default=75)] where DSF ILM will kick in and as part of a Curator job will down-migrate data from the SSD tier to the HDD tier. This will bring utilization within the threshold mentioned above or free up space by the following amount [curator_tier_free_up_percent_by_ilm (Default=15)], whichever is greater. The data for down-migration is chosen using last access time. In the case where the SSD tier utilization is 95%, 20% of the data in the SSD tier will be moved to the HDD tier (95% \u2013> 75%).","className":"post__content__best_answer"}">

    \nI have a case open for this with Nutanix Support, however, while I'm waiting...

    \nI'm wondering if anyone can explain why in a block that contains 12HDDs and 6SSDs (3-node block), only shows disk statistics for the SSDs and no values for the HDDs in the list (all metrics are 0).

    从Nutanix圣经中。。。您的SSD不够饱满，以至于ILM无法启动并将容量移至HDD。

    另一种情况是，当总体利用率违反特定阈值[curator_tier_usage_ilm_threshold_percent（默认= 75）]中，DSF ILM将启动，并且作为策展人的一部分，策展人工作将下降从SSD Tier到HDD Tier。这将带来上述阈值的利用率，或者以以下数量释放空间[curator_tier_free_up_percent_by_ilm（default = 15）]，以更大为准。使用最后一次访问时间选择下降迁移的数据。在SSD层利用率为95％的情况下，SSD层中20％的数据将移至HDD层（95％ - > 75％）。
