# 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.
