HPE 859084-S01 ProLiant DL380 Gen9 Rack Server

The HPE ProLiant DL380 Gen9 represents a pinnacle in enterprise server design, balancing exceptional performance, legendary reliability, and remarkable scalability. As a cornerstone of data centers worldwide, the Gen9 series built upon the trusted DL380 lineage with the introduction of the Intel Xeon E5-2600 v4 family and DDR4 memory. The specific smart buy model 859084-S01 encapsulates this legacy in a highly capable, storage-rich configuration, engineered for critical workloads including virtualization, database hosting, collaboration applications, and medium-duty enterprise resource planning (ERP).

Core Architecture & Processing Power

At the heart of this server lies a robust processing foundation designed for efficient multi-threaded performance and future upgradability.

Intel Xeon E5-2620 v4 Processor

This server is powered by a single Intel Xeon E5-2620 v4 processor. This 8-core CPU operates at a base frequency of 2.1 GHz, with the capability to intelligently scale higher via Intel Turbo Boost Technology 2.0. With 16 threads thanks to Hyper-Threading, it excels in parallelized tasks. It features a 20MB shared L3 cache, significantly reducing latency for frequently accessed data.

Platform Scalability

The DL380 Gen9 platform is inherently dual-processor capable. The inclusion of a single E5-2620 v4 in this configuration provides a clear, cost-effective growth path. Organizations can add a second identical processor at any time to effectively double their core count, thread count, and memory capacity, protecting initial investment and seamlessly accommodating workload growth without a platform migration.

Performance and Capacity

This system is equipped with 64GB of DDR4 RAM, configured as four 16GB modules. The move to DDR4 technology from DDR3 in the Gen9 series delivered substantial benefits, including higher data transfer rates (in this case, 2400 MT/s), improved data integrity via on-die ECC, and significantly lower operating voltage (1.2V), which reduces power consumption and thermal output. The 64GB capacity provides ample headroom for running multiple virtual machines, in-memory databases, or large application sets.

Memory Architecture and Expansion

The DL380 Gen9 features a 24-DIMM slot architecture (12 per processor). In this single-CPU configuration, 12 slots are available. With four slots populated, eight slots remain free for effortless expansion. The system supports LRDIMMs and RDIMMs, allowing memory capacity to scale up to 768GB with a single CPU or an immense 1.5TB with two processors installed, ensuring the server can grow alongside the most demanding applications.

Storage & Data Integrity Engine

This model is configured for maximum storage flexibility and high-performance data protection, a hallmark of the ProLiant series.

24-SFF Drive Bay Chassis

The 24 Small Form Factor (SFF) drive bay chassis is a defining feature. Supporting 2.5-inch drives, this configuration allows for an exceptional density of storage devices. This is ideal for environments where high I/O operations per second (IOPS) are critical, as 2.5-inch SAS and SATA SSDs can be deployed in large numbers for a massive performance boost. It also allows for mixing drive types—SSDs for tier-1 performance-sensitive data and HDDs for capacity—within the same unified enclosure.

HPE Smart Array P440ar Controller with SAS Expander

Data protection and performance are managed by the embedded HPE Smart Array P440ar/2GB controller. This is a 12 Gb/s SAS hardware RAID controller featuring 2GB of battery-backed (Flash-Backed Write Cache) FBWC. The "ar" designation indicates it is integrated onto the system board for optimized space and signal integrity. The 2GB of cache dramatically accelerates both read and write operations, while the included Smart Storage Battery ensures that all data in the cache is preserved and flushed to non-volatile storage in the event of a power failure, guaranteeing data integrity.

SAS Expander Integration

The inclusion of a SAS Expander chip is crucial for the 24-bay configuration. It allows all 24 drive bays to be connected and managed by the single P440ar controller without any performance bottleneck, providing a full 12 Gb/s pathway to each drive. This enables complex RAID configurations (RAID 0, 1, 5, 6, 10, 50, 60) across the entire drive set, allowing administrators to balance performance, capacity, and redundancy to match exact application needs.

Connectivity & Network Infrastructure

Comprehensive and flexible networking is built directly into the system, reducing the need for additional adapter cards for basic connectivity.

HPE Ethernet 1Gb 4-port 331i Adapter

The server comes standard with the HPE Ethernet 1Gb 4-port 331i Adapter. This is a flexible LOM (LAN on Motherboard) solution offering four independent 1 Gigabit Ethernet ports. These ports support advanced features like failover network teaming (NIC Teaming) and load balancing, which increase network throughput and provide crucial redundancy. If one network path fails, traffic automatically reroutes to another active port, ensuring continuous application availability—a critical feature for virtualization hosts and servers.

Platform Design & Power Infrastructure

The physical and power design of the DL380 Gen9 focuses on resilience, serviceability, and efficiency.

2U Rack-Optimized Form Factor

The 2U rack server design is the industry standard for balance between density and capability. It allows 24 drive bays and substantial processing power while only consuming two rack units (approximately 3.5 inches) of vertical space in a standard 19-inch rack. HPE's tool-less design facilitates easy maintenance; components like drives, power supplies, fans, and expansion cards can be serviced or replaced without requiring tools, minimizing system downtime for hardware updates.

High-Efficiency 800W Power Supply System

This configuration includes two 800W Platinum-rated high-efficiency power supplies configured for 1+1 redundancy. In this mode, both power supplies share the load actively. If one power supply fails or its power cord is disconnected, the other instantly assumes the entire system load without any interruption. The Platinum efficiency rating (94%+ efficient at typical loads) ensures minimal power loss as heat, reducing operational cooling costs. The 800W capacity provides substantial headroom for populating all drive bays with SSDs/HDDs and adding additional PCIe cards, including GPUs or higher-powered CPUs.

Security Features

HPE's integrated management suite provides unparalleled control and insight into server health and operation.

HPE iLO 4 (Integrated Lights-Out 4)

Every ProLiant DL380 Gen9 is equipped with the dedicated HPE iLO 4 management processor. This provides full, remote, browser-based management of the server independent of the host operating system. Administrators can perform tasks such as power cycling the server, mounting virtual media (ISO images) for OS installation, viewing hardware status logs, and accessing the console remotely as if they were physically in front of the server. This is invaluable for managing servers in remote data centers or branch offices.

HPE ProLiant Gen9 Security

The server platform includes HPE's unique Silicon Root of Trust and Sure Start technologies. The Root of Trust ensures that the iLO firmware is authentic and unmodified at boot. Sure Start actively protects, detects, and automatically recovers the iLO firmware from corruption or malicious attacks. This hardware-enforced security provides a foundational layer of protection against low-level threats.
