Understanding the intricacies of this configuration is crucial for maximizing its potential and ensuring long-term stability. This document assumes a working knowledge of Server Hardware Basics and Virtualization Technologies.
1. Hardware Specifications
The Cloud Architecture configuration is built around a modular design, allowing for customization based on specific requirements. The following specifications represent a typical deployment.
Processor (CPU): Dual Intel Xeon Platinum 8480+ (56 cores/112 threads per CPU, Base Frequency 2.0 GHz, Max Turbo Frequency 3.8 GHz, 350W TDP). These processors utilize the Sapphire Rapids architecture, offering significant improvements in core count, cache size, and memory bandwidth compared to previous generations. They also include built-in acceleration for cryptographic operations and AI workloads. See also CPU Architecture Overview.
Memory (RAM): 2TB DDR5 ECC Registered RDIMM (8 x 256GB modules) running at 4800 MHz. Utilizing Registered DIMMs ensures data integrity and stability in high-density configurations. The large memory capacity supports demanding applications and large virtual machine deployments. Memory is configured in a multi-channel configuration to maximize bandwidth. Refer to Memory Technologies for detailed information on DDR5.
Storage (Primary): 8 x 3.2TB NVMe PCIe 4.0 SSDs in RAID 10 configuration. NVMe SSDs provide extremely low latency and high throughput, essential for virtual machine boot times and application performance. RAID 10 provides both performance and redundancy. We utilize enterprise-grade SSDs with high DWPD (Drive Writes Per Day) ratings for increased endurance. See Storage Technologies Overview.
Storage (Secondary/Object Storage): 24 x 18TB SAS 7.2K RPM HDDs in RAID 6 configuration. This provides a large capacity, cost-effective storage tier for archival data, backups, and object storage. RAID 6 offers excellent data protection with dual parity. Consider Data Storage Redundancy for details on RAID levels.
Network Interface Cards (NICs): 2 x 200GbE Mellanox ConnectX-7 NICs with RDMA support. These high-bandwidth NICs provide low-latency connectivity for virtual machines and containerized applications. RDMA (Remote Direct Memory Access) allows for direct memory access between servers, reducing CPU overhead and improving performance. See Networking Technologies.
Expansion Slots:
- 3 x PCIe 5.0 x16 slots
