ScalarCloud Europe 2025 infrastructure: updates and improvements
Posted by brain in Cloud on 27 novembre 2024 with No Comments
Hello everyone, we have just validated the new ScalarCloud Europe 2025 infrastructures, and the hardware order was placed today.
The old ScalarCloud infrastructures (2021):
– Processor: 2 × Intel Xeon Gold 6242R – 20c/40t
– RAM: 768 GB ECC 2933 MHz
– Storage: 12 × 3.84 TB NVMe SSD (2 arrays of 6 NVMe SSDs in RAID 10)
Redundant connection: 2 x 10 Gb/s
Points of presence: UK (ERI), DE (LIM), FR (RBX, GRA)
The new ScalarCloud infrastructures (2025):
– Processor: 2 x Dual AMD Epyc 9354 – 64c/128t
– RAM: 1.5TB DDR5 ECC 4800 MHz
– Storage: 18 x 3.84 TB NVMe SSD (3 arrays of 6 NVMe SSDs in RAID 10)
Redundant connection: 2 x 25 Gb/s
Points of presence: FR (RBX, GRA, SBG), DE (LIM).
Health Certification HDS.
In summary: we will close the ERI (UK) site, replaced by Strasbourg, as Brexit has caused too many certification issues with some European clients.
The HDS (health certification) will become the default for our infrastructures.
We maintain the same hardware policy: no compromises on performance. The new AMD Epyc 9354 delivers better performance across the board and increases memory bandwidth from 140.8 to 460.8 GB/s.
On the network side, we move from a redundant connection standard of 10 to 25 Gb/s.
Finally, on the storage side, the standard of 2 RAID arrays is now upgraded to 3.
Currently, the 2 separate arrays allow clients who need ultra-performing and highly available local backup space to do so without relying on network services.
The 3rd array strengthens the setup with a spare array that allows more effective, secure, and faster switching in case of hardware failure:
1) Local migration to the spare array to immediately secure the data.
2) Migration of VMs to another node after data security.
3) Hardware maintenance on the initial node.
4) Testing and validation.
5) Returning to the initial node.

Evolution of ScalarCloud Backup Infrastructure / PBS (Proxmox Backup Server)
Posted by brain in Cloud on 26 octobre 2024 with No Comments
Hello everyone, we are currently setting up a new backup infrastructure for our hosting clients (ScalarCloud).
To address the overlap issues that can sometimes occur, especially during nighttime network slowdowns on the OVH network currently in use, the new infrastructure will no longer be shared.
From now on, each node will have its own independent PBS (Proxmox Backup Server) as well as a dedicated 25 Gb/s interconnection for this purpose.
Have a great weekend, everyone!

Backup’s billing
Posted by brain in Non classé on 25 avril 2024 with No Comments
Good evening everyone,
After our year-end inventories, we have realized that we significantly underestimated the volume of backups our clients would use. Currently, as I write this message, we are spending more on storing client backups than we are billing for them.
This situation will lead to several actions and communications to rectify the issue. What does this mean for you in practice?
Firstly, the price of backups will not change: it is still billed per GB provisioned, and we do not plan to change the billing system.
Currently, there are two main types of accounts:
Clients and partners.
Partners are theoretically adjusted based on actual consumption, but as with any rule, there are exceptions: in practice, the backup volume is not adjusted to actual consumption, but rather to the exact impact of the raw storage cost for us. Simply put, this means that in the best case scenario, the applied margin is 0% (not considering operational costs).
For non-partner clients, the only adjustments made relate to the ratio with the consumed production storage. For example, for a client who used 100G of space and had an associated backup volume of 100G, if the production storage increased to 200G, then the backup was increased proportionally.
As we dislike surprises and assume you do too, here is how we will proceed:
1) We will conduct a thorough audit of each partner and client one-on-one (some have consolidated backups shared across several infrastructures, etc.)
2) We will individually come back to each of you with these values, and options from which you will be free to choose the one that suits you best, including:
– Adjusting the billed amount to the actual consumption
– Modifying the current retention to reduce the space used
– Excluding certain elements (highlighting associated risks)
– For ScalarCloud or PrivateCloud clients: limiting to one type of backup rather than two.
– Pointing out « suspicious » consumption in the user space that you might be able to do without, which will allow for less backup volume usage.
In summary, there will be many options allowing each of you to find what works best and choose the most suitable backup policy for your situation.
Wishing you an excellent end of the week in advance.

Update on Supported Versions for Different Versions of StackX (Debian)
Posted by brain in Non classé on 5 janvier 2024 with No Comments
Hello everyone, we have created a new page that lists the different versions of PHP, MySQL, and MariaDB supported on the various versions of StackX.
More software and versions will be added to the table soon. This page is now integrated into the site’s menu and will be updated throughout the life cycle of StackX to provide better visibility on the different possible combinations according to your needs.
However, it should be noted that MariaDB version 10.3 is no longer supported from the official MariaDB repositories. It is the version originally shipped with Debian Buster that still allows this support.
Finally, unlike MySQL and MariaDB versions where only one version is supported per instance, several PHP applications/sites with different versions (5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, 8.1, 8.2, and 8.3) can naturally coexist on the same server.

Hypervisor Update
Posted by brain in Cloud on 23 décembre 2023 with No Comments
End-of-year update for all Proxmox VE hypervisors, which form the backbone of the ScalarCloud Public Cloud infrastructure.
Based on the tests we have conducted over the past month, we will for now retain the 7.4 branch of Proxmox VE for the Public Cloud’s production clusters.
We will schedule an update once all our tests are 100% conclusive. (In any case, there is no impact from your side for which this part is invisible).
No service interruption is expected, as machines are moved live from node to node during the updates before returning to their original location.
Increase in Local ScalarCloud SSD NVMe RAID Storage Capacities
Posted by brain in Cloud on 20 septembre 2023 with No Comments
Hello everyone, in response to the accelerated demand for space in recent months, we will soon be increasing the SSD NVMe storage capacity of our ScalarCloud platform.
These upgrades will be carried out in stages and node by node. No service interruptions are expected.
The process will be similar to hypervisor updates.
Your machines will be moved live and distributed to other standby nodes during the operation, and then return to their original location.
After that, a balancing via distribution will be performed: some virtual machines will retain their NVMe virtual storage on the first volume, and others will be moved (live) to the second volume.
These operations will start on October 3rd and aim to double the current RAID 10 storage capacity by adding a new matrix, allowing us to increase from 24 TB NVMe per node to 48 TB.
The end date of these operations is not yet known, as it requires coordination with OVHcloud node by node for the hardware upgrades. We will keep you informed when these operations are completed.
Have a great end to your weekend.
StackX Now Available for Debian 12 Bookworm
Posted by brain in Services managés on 28 août 2023 with No Comments
Hello everyone, our managed LAMP (Linux, Apache, MariaDB/MySQL, and PHP) solution StackX is now available for Debian 12 Bookworm.
This brings the total to three currently supported versions: Debian 10, Debian 11, and Debian 12.
The installable versions of MariaDB & MySQL are those available on their respective official repositories. The versions of MariaDB covered by StackX range from 10.3 to 11.2.
The supported versions of PHP remain the same across the three versions of Debian (Buster, Bullseye, and Bookworm):
| PHP 5.6 PHP 7.0 PHP 7.1 PHP 7.2 PHP 7.3 | PHP 7.4 PHP 8.0 PHP 8.1 PHP 8.2 PHP 8.3 |
It is still possible to mix these different versions across multiple sites/applications.
We will soon publish an online table summarizing the versions of the main software supported for each version of StackX.
Have a great week everyone.
