## Resource types
*CPU* and *memory* are each a *resource type*. A resource type has a base unit.
CPU is specified in units of cores, and memory is specified in units of bytes.
If you're using Kubernetes v1.14 or newer, you can specify _huge page_ resources.
Huge pages are a Linux-specific feature where the node kernel allocates blocks of memory
that are much larger than the default page size.
For example, on a system where the default page size is 4KiB, you could specify a limit,
`hugepages-2Mi: 80Mi`. If the container tries allocating over 40 2MiB huge pages (a
total of 80 MiB), that allocation fails.
{{< note >}}
You cannot overcommit `hugepages-*` resources.
This is different from the `memory` and `cpu` resources.
{{< /note >}}
CPU and memory are collectively referred to as *compute resources*, or just
*resources*. Compute
resources are measurable quantities that can be requested, allocated, and

*CPU* 和*内存*都是*资源类型*。资源类型具有基本单位。CPU 的单位是核心数,内存的单位是字节。
如果您使用的是Kubernetes v1.14或更高版本则可以指定巨大页资源。巨大页是Linux特有的功能节点内核在其中分配的内存块比默认页面大小大得多。
例如在默认页面大小为4KiB的系统上您可以指定一个限制`hugepages-2Mi80Mi`。如果容器尝试分配40多个2MiB大页面a总共80 MiB则分配失败。
{{< note >}}
您不能过量使用`hugepages- *`资源。
这与`memory`和`cpu`资源不同。
{{< /note >}}
CPU和内存统称为*计算资源*,也可以称为*资源*。计算资源的数量是可以被请求、分配、消耗和可测量的。它们与 [API 资源](/docs/concepts/overview/kubernetes-api/) 不同。 API 资源(如 Pod 和 [Service](/docs/concepts/services-networking/service/))是可通过 Kubernetes API server 读取和修改的对象。
