M3 Aggregator - Capabilities and Limitations

Last updated July 13, 2022

Objective

This page provides the technical capabilities and limitations of the Public Cloud Databases' M3 aggregator offer.

We continuously improve our offers. You can follow and submit ideas to add to our roadmap at https://github.com/ovh/public-cloud-roadmap/projects/2.

Capabilities and limitations

Supported regions and multi-AZ

The Public Cloud Databases offer is available in the following regions:

• BHS (Beauharnois, Canada)
• DE (Frankfurt, Germany)
• GRA (Gravelines, France)
• SBG (Strasbourg, France)
• UK (London, United Kingdom)
• WAW (Warsaw, Poland)

The entire database instances must be in the same region. Multi-AZ is currently not supported.

M3 Aggregator versions

The Public Cloud Databases offer supports the following M3 aggregator versions:

• m3 aggregator 1.1
• m3 aggregator 1.2

Plans

Two plans are available:

• Business
• Enterprise

Here is an overview of the various plans' capabilities:

Plan	Number of nodes by default	Additional nodes	Network
Business	3	No	Public & Private vRack
Enterprise	6	No	Public & Private vRack

Your choice of plan affects the number of nodes your cluster can run.

Nodes and replicas

• Business: The cluster is delivered with 3 nodes by default.
• Enterprise: The cluster is delivered with 6 nodes by default.

License type

Each cluster is provided with the M3 Aggregator Community (GPL) license.

Where applicable, the cost of the license is included in the service plans. It is not possible to bring your own licenses.

Hardware resources

Here are the node types you can choose from:

Business plans

Name	Disk (GB)	Cores	Memory (GB)
db1-7	N/A	2	7
db1-15	N/A	4	15
db1-30	N/A	8	30
db1-60	N/A	16	60
db1-120	N/A	32	120

Enterprise plans

Name	Disk (GB)	Cores	Memory (GB)
db1-15	N/A	4	15
db1-30	N/A	8	30
db1-60	N/A	16	60
db1-120	N/A	32	120

Right now, all nodes in a given cluster must be of the same type and located in the same region.

Features

Network

Public networking can be used for all the offers.

Private networking (vRack) is available for Business and Enterprise.

When using private networking, some network ports get created in the private network of your choice. Thus, further operations on that network might suffer from some restrictions - e.g. you won't be able to delete the network if you didn't stop the Public Cloud Databases services first.

Ingress and Egress traffic are included in the service plans and unmetered.

Logs and metrics

Logs and metrics are available via the OVHcloud Public Cloud Control Panel. As of today, you can't export logs and metrics, nor plug them into a remote tool.

• Logs retention: 1000 lines of logs
• Metrics retention: 1 calendar month

Please note that if the database instance is deleted, logs and metrics are also automatically deleted.

We want your feedback!

We would love to help answer questions and appreciate any feedback you may have.
