# Show Memory Resources

Show the total Intel Optane DC persistent memory resource allocation across the host server.

```
ipmctl show [OPTIONS] -memoryresources
```

## **Example**

Show persistent memory module resource allocation.

```
$ ipmctl show -memoryresources

Capacity=1517.0 GiB
MemoryCapacity=0.0 GiB
AppDirectCapacity=1512.0 GiB
UnconfiguredCapacity=0.0 GiB
InaccessibleCapacity=5.0 GiB
ReservedCapacity=0.0 GiB
```

## **Return Data**

* `MemoryCapacity`: Total usable system persistent memory for Memory Mode.
* `AppDirectCapacity`: Total usable system persistent memory for App Direct mode.
* `UnconfiguredCapacity`: Total system persistent memory capacity that is unusable because it has not been configured.
* `ReservedCapacity`: Total system persistent memory capacity that is reserved. This capacity is the persistent memory partition capacity (rounded down for alignment) less any App Direct capacity. Reserved capacity typically results from a Memory Allocation Goal request that specified the Reserved property. This capacity is not mapped to system physical address (SPA) space.
* `InaccessibleCapacity`: Total system persistent memory capacity that is inaccessible due any of:
  * Platform configuration prevents accessing this capacity. e.g. MemoryCapacity is configured but MemoryMode is not enabled by platform FW (current operating mode is 1LM).
  * Capacity is inaccessible because it is not mapped into the system physical address space (SPA). This is usually due to platform firmware memory alignment requirements.
  * Intel Optane DC persistent memory is configured but SKU prevents usage. e.g. AppDirectCapacity but  SKU is MemoryMode only.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.pmem.io/ipmctl-user-guide/v1.x/module-discovery/show-memory-resources.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
