Concepts

The Bare Metal offering from Cloud Temple provides dedicated physical servers coupled with a distributed block storage solution.
This solution offers full customization for customers who wish to manage their own software environments, whether installing a Linux or Windows system, or a hypervisor.

A flexible and robust hardware infrastructure

The Bare Metal offering is based on an architecture designed to meet the requirements of critical workloads.

Hauptkomponenten

• Cisco UCS-Server: Leistungsstark und zuverlässig, bilden diese Compute-Lanes die Grundlage des Angebots.
• IBM Spectrum Virtualize-Speicher: Ein verteiltes Blockspeichersystem, das Resilienz und hohe Leistung bietet.

Architecture

The distributed storage model provides a separation between computing (Bare Metal servers) and storage (distributed block), enabling:

• Flexibility to map storage volumes across multiple Bare Metal servers according to requirements.
• Optimal customization of computing and storage configurations.
• Enhanced resilience through the use of Distributed RAID 6.

Regions and Availability Zones

The Bare Metal product is deployed within an availability zone.
An availability zone is part of a region.

This deployment model allows you to select the location of your Bare Metal servers and distribute them across different availability zones (AZs).
This provides better load distribution, maximizes redundancy, and simplifies the implementation of a disaster recovery plan (DRP) in the event of an incident.

Compute Blade Classes

The available compute blades for the Bare Metal offering provide a range of performance options to meet diverse requirements:

Reference	RAM (1)	Frequency (2)	Number of Cores / Threads	Connectivity (3)	GPU (4)
ECO	384 GB	2.20/3.0 GHz (Silver 4114 or equivalent)	20 / 40 threads	2 × 10 Gbit/s	-
STANDARD	384 GB	2.40/3.4 GHz (Silver 4314 or equivalent)	32 / 64 threads	2 × 25 Gbit/s	-
ADVANCE	768 GB	2.80/3.5 GHz (Gold 6342 or equivalent)	48 / 96 threads	2 × 25 Gbit/s	-
PERFORMANCE 1	384 GB	3.20/3.6 GHz (Xeon E-53I5Y or equivalent)	16 / 32 threads	2 × 25 Gbit/s	-
PERFORMANCE 2	768 GB	3.00/3.6 GHz (Gold 6354 or equivalent)	36 / 72 threads	2 × 25 Gbit/s	-
PERFORMANCE 3	1536 GB	2.60/3.5 GHz (Gold 6348 or equivalent)	56 / 112 threads	2 × 25 Gbit/s	-
PERFORMANCE 4	512 GB	2.50/4.1 GHz (Intel 6426Y or equivalent)	32 / 64 threads	2 × 25 Gbit/s	2 × NVIDIA L40S 48GB

Notes

• (1) The amount of memory is the physically available memory on the blades and cannot be modified.
• (2) The frequencies listed correspond to the minimum base frequency and the turbo frequency.
• (3) Physical connectivity is shared for network access and block storage access, thanks to a converged Cisco UCS architecture.
• (4) Available GPUs evolve with the latest technologies. As of May 1, 2024, the offering includes NVIDIA LOVELACE L40S GPUs.

Infrastructure availability is guaranteed at 99.9%, measured monthly, including maintenance windows. Any SLA-related request must be reported via an incident ticket.

Block Storage Classes

Distributed block storage, based on IBM Spectrum Virtualize, offers a range of performance tiers suited for various use cases:

Reference	IOPS/To	Primary Use Case
FLASH - Essential	500	Light workloads
FLASH - Standard	1500	Standard workloads
FLASH - Premium	3000	Intensive workloads
FLASH - Enterprise	7500	Critical workloads
FLASH - Ultra	15000	Ultra-intensive workloads
MASS STORAGE - Archival	Not applicable	Cost-effective storage for archiving

Features

• Technology: Flash NVMe with Distributed RAID 6 for enhanced resilience.
• Availability: 99.99%, measured monthly.
• Restrictions: No limits on reads or writes. No automatic compression or deduplication, ensuring full utilization of allocated volumes.

Storage Block Security and Encryption

To ensure the confidentiality of your data at rest, our entire block storage infrastructure integrates a robust hardware-based encryption.

• Encryption Type: Data is encrypted directly on the disks (Data At Rest) using the XTS-AES 256 algorithm.
• Compliance: This encryption method complies with the FIPS 140-2 standard, ensuring a high level of validated security.
• Operation: Encryption is applied at the time data is written to the physical storage medium.

Attention regarding replication

It is important to note that this encryption protects data stored on disks. It is not active "on-the-fly," meaning data is not encrypted during storage replication operations between availability zones. Security of transfers is ensured through dedicated and secure communication channels.

Bare Metal Console Access

Access to Bare Metal servers is provided directly from the Cloud Temple console. This feature offers full control over the server lifecycle, including:

• KVM Access: A direct interface to manage servers, as if you were physically on-site.
• Management of common operations: Ability to perform actions such as power management, reboots, and ISO mapping for operating system installation.

This level of access ensures maximum flexibility while maintaining strict security requirements.

Bare Metal Server Networking

Bare Metal servers come with advanced networking capabilities.

Layer 2 VLANs

It is possible to configure Layer 2 VLANs on the network interfaces of Bare Metal servers. Users can:

• Enable VLAN tagging to associate one or more VLANs with a single interface.
• Propagate VLANs directly on the network interfaces of the Bare Metal servers.

Network Interface Aggregation

Each server is equipped with two network interfaces. These interfaces can be used either independently or combined to achieve improved performance and redundancy:

Network Performance

The performance of network interfaces is directly linked to the chosen blade class. Example:

• ECO blades provide connectivity of 2 x 10 Gbit/s.
• STANDARD and higher-class blades offer connectivity of 2 x 25 Gbit/s.

These network options ensure reliable, flexible, and workload-adapted connectivity for a wide range of professional workloads.
