# Supported machine types and storage

## Supported machine types for backends

The following table provides the supported machine types (VM instance) for backends (and clients) applied by the Terraform package:

<table><thead><tr><th width="183">Machine series</th><th>Machine types</th></tr></thead><tbody><tr><td>C2</td><td>c2-standard-8, c2-standard-16</td></tr><tr><td>N2</td><td>n2-standard-8, n2-standard-16</td></tr></tbody></table>

{% hint style="info" %}

* WEKA supports deploying the C2 machine type with 2, 4, or 8 local SSD drives and the N2 machine type with 2, 4, 8 or 16 local SSD drives. Each drive has 375 GB (maximum 3 TB per instance). These drives are not individual SSDs but partitions locally to the physical server.
* The data in a WEKA cluster is protected with N+2 or N+4. However, use snap-to-object if the data needs further protection from multiple server failures.
* The C2 series may not be available in your chosen [GCP region](https://cloud.google.com/compute/docs/regions-zones).&#x20;

## Supported machine types for clients

Explore the two key technologies in network virtualization: **VirtIO in DPDK mode** and **gVNIC in UDP mode**. VirtIO in DPDK mode offers high-performance network interfaces in virtual machines, while gVNIC in UDP mode provides reliable, high-speed network connectivity.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.weka.io/4.3/planning-and-installation/weka-installation-on-gcp/supported-machine-types-and-storage.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
