为什么我不能将AWS的新st1/sc1 EBS卷用作根卷 [英] Why can't I use the new st1/sc1 EBS volumes by AWS as root volumes

问题描述

AWS最近启动了sc1和st1 HDD EBS卷类型，在启动新的EC2实例或从已经创建的AMI启动时，我似乎无法将它们用作根卷.

AWS launched sc1 and st1 HDD EBS volume types recently, I can't seem to use these as root volumes while launching new EC2 instances or launching from already created AMI's (tried both).

我选择了一台m4机器，无论如何，根卷是EBS本身，下面是截图，我添加的第二个卷获得了新选项，但是第一个我不能选择相同的卷.这是特意为AWS的人吗?

I chose an m4 machine, in any case, the root volume is EBS itself, below is a screenshot, the second volume that I add gets the new options, however the first one I can't choose the same. Is this by design AWS people?

推荐答案

如果您从 http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html

表示

不能是启动卷

Cannot be a boot volume

及以下

吞吐量优化的HDD(st1)卷可提供低成本的磁性 根据吞吐量而不是性能定义性能的存储 IOPS.此卷类型非常适合大型顺序工作负载 例如Amazon EMR，ETL，数据仓库和日志处理. 可启动 不支持st1卷.

Throughput Optimized HDD (st1) volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. This volume type is a good fit for large, sequential workloads such as Amazon EMR, ETL, data warehouses, and log processing. Bootable st1 volumes are not supported.

和

冷HDD(sc1)卷提供了低成本的磁存储，该磁存储定义了 性能方面的吞吐量，而不是IOPS.用较低的 吞吐量限制比st1大，sc1非常适合大型， 顺序冷数据工作负载.如果您不需要经常访问 您的数据并希望节省成本，sc1提供了廉价 块存储. 不支持可启动sc1卷.

Cold HDD (sc1) volumes provide low-cost magnetic storage that defines performance in terms of throughput rather than IOPS. With a lower throughput limit than st1, sc1 is a good fit ideal for large, sequential cold-data workloads. If you require infrequent access to your data and are looking to save costs, sc1 provides inexpensive block storage. Bootable sc1 volumes are not supported.
