# Technical Features

The specifications of a Plenit server. To decide what size you need, go to [Size your server](/docs-en/productos/servers/concepts/size-cpu-ram-disk.md) in Concepts.

### Compute

|           |                           |
| --------- | ------------------------- |
| vCPU      | Up to 32                  |
| RAM       | Up to 128 GB              |
| Processor | Intel Xeon Scalable       |
| Scaling   | Hot, without reinstalling |

### Storage

|             |                                 |
| ----------- | ------------------------------- |
| Technology  | NVMe · NetApp All-Flash (ONTAP) |
| System disk | From 60 GB                      |
| Data disks  | Additional, each with backup    |
| Resizing    | Hot expansion                   |

Shrinking a disk is more delicate than expanding it; the procedure is in How-to.

### Hardware

|              |                         |
| ------------ | ----------------------- |
| Servers      | Dell                    |
| Processor    | Intel Xeon Scalable     |
| Memory       | DDR5 ECC                |
| Redundancy   | N+1 cluster             |
| Power        | Dual power supply (PSU) |
| Host network | Aggregated links (LAG)  |

If a cluster host fails, its virtual machines restart on another available host. This is the resilience of the physical infrastructure; the zone-based high availability design is up to you (you'll see it in Concepts when it's available).

### Virtualization

|               |                   |
| ------------- | ----------------- |
| Hypervisor    | KVM               |
| Orchestration | Apache CloudStack |

### Physical network

|                        |            |
| ---------------------- | ---------- |
| Architecture           | Spine-leaf |
| Network virtualization | VXLAN      |

# 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 dynamically by asking a question.

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

```
GET https://docs.plenit.com/docs-en/productos/servers-2/details/technical-specs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
