Colocation Data Center
- Colocation Data Center Configuration: A Deep Dive
This document details a typical "Colocation Data Center" server configuration, outlining its hardware specifications, performance characteristics, ideal use cases, comparisons to similar setups, and essential maintenance considerations. This configuration is designed for businesses seeking to leverage the benefits of a professionally managed data center environment without the capital expenditure and operational overhead of building and maintaining their own facilities.
1. Hardware Specifications
The Colocation Data Center configuration, as detailed here, represents a high-density, scalable solution. Specific components can vary based on provider and service level agreements (SLAs), but the following represents a common baseline. We'll detail a 1U server as the fundamental building block, as this is the most common form factor in colocation environments. Scalability is achieved by adding more servers within the allocated rack space. This document assumes a dedicated 1U server instance.
1.1. CPU
The CPU is the heart of the server. For a typical colocation setup, we recommend dual Intel Xeon Gold 6348 processors.
| Feature | Specification |
|---|---|
| Manufacturer | Intel |
| Model | Xeon Gold 6348 |
| Core Count | 28 cores per processor |
| Thread Count | 56 threads per processor |
| Base Clock Speed | 2.6 GHz |
| Max Turbo Frequency | 3.8 GHz |
| Cache | 42 MB Intel Smart Cache (21MB per processor) |
| TDP | 205W |
| Socket Type | LGA 4189 |
This choice provides a strong balance of core count, clock speed, and power efficiency, making it suitable for a wide range of workloads. Alternative options include AMD EPYC 7543P, offering similar performance characteristics. See CPU Comparison for a detailed comparison of CPU architectures.
1.2. RAM
Memory is critical for performance. We specify 256GB of DDR4 ECC Registered memory.
| Feature | Specification |
|---|---|
| Type | DDR4 ECC Registered |
| Capacity | 256 GB (8 x 32GB DIMMs) |
| Speed | 3200 MHz |
| Form Factor | DIMM |
| Memory Channels | 8 per processor |
| Latency | CL22 |
ECC Registered memory is vital for server stability and data integrity. The 3200MHz speed balances performance with cost-effectiveness. Higher capacity configurations (512GB or 1TB) are available for memory-intensive applications. See Memory Technologies for more information on RAM types.
1.3. Storage
Storage is a critical aspect of the configuration. We utilize a hybrid approach: a fast NVMe SSD for the operating system and applications, combined with high-capacity SATA SSDs for data storage.
| Feature | Specification |
|---|---|
| OS Drive | 500GB NVMe PCIe Gen4 SSD |
| Data Drives | 4 x 4TB SATA SSD |
| RAID Controller | Hardware RAID Controller with 12Gbps SAS interface (RAID 10 configuration for data drives) |
| Interface | NVMe PCIe Gen4, SATA III |
| Hot-Swappable | Yes (for data drives) |
RAID 10 provides excellent performance and redundancy for the data drives. NVMe SSDs offer exceptionally fast read/write speeds for the operating system and frequently accessed applications, significantly improving overall system responsiveness. See Storage Solutions for a detailed overview of storage technologies.
1.4. Networking
Networking is paramount in a colocation environment.
| Feature | Specification |
|---|---|
| Network Interface Card (NIC) | Dual Port 10 Gigabit Ethernet (10GbE) |
| Network Connectivity | Dedicated port(s) to colocation provider's network |
| MAC Address | Unique MAC address per port |
| Supported Protocols | TCP/IP, UDP, VLAN, etc. |
| Remote Management | IPMI 2.0 over dedicated network |
The 10GbE connectivity ensures ample bandwidth for data transfer. Dedicated ports minimize latency and contention. The IPMI 2.0 interface allows for remote server management, crucial for colocation environments. See Networking Fundamentals for a detailed explanation of networking concepts.
1.5. Power Supply
Reliable power is essential.
| Feature | Specification |
|---|---|
| Power Supply Unit (PSU) | Redundant 80 PLUS Platinum 750W Power Supplies |
| Input Voltage | 200-240V AC |
| Output Voltage | 12V, 5V, 3.3V |
| Efficiency | 94% at 50% load |
| Redundancy | 1+1 Redundancy |
Redundant, high-efficiency power supplies ensure uptime even in the event of a PSU failure. The 80 PLUS Platinum certification guarantees efficient power usage, reducing operational costs. See Power Management for details on PSU efficiency ratings.
1.6. Motherboard & Chassis
The motherboard and chassis provide the foundation for the entire system.
| Feature | Specification |
|---|---|
| Motherboard Chipset | Intel C621A |
| Form Factor | 1U Rackmount Chassis |
| Expansion Slots | 1 x PCIe 4.0 x16, 1 x PCIe 3.0 x8 |
