Dell Minicard PERC H740P RAID Controller
Overview
The Dell Minicard PERC H740P is a high‑performance, enterprise‑grade RAID controller designed for data centers and mission‑critical workloads. Built on the robust LSI processor family, it delivers exceptional throughput, low latency, and advanced storage features while maintaining a compact form factor suitable for Dell’s MiniCard platform.
Key Technical Specifications
- Processor: Integrated LSI controller with built‑in processing capabilities.
- Channels: Eight independent SAS/SATA channels, enabling simultaneous data paths for maximum bandwidth.
- PCI Express Interface: x8 PCIe 3.1, providing a theoretical peak of 12 Gbit/s per lane and ensuring compatibility with modern server motherboards.
- Internal Memory: 8192 MB (8 GB) dedicated cache for rapid data access and efficient RAID operations.
- Supported RAID Levels: 0, 1, 5, 6, 10, 50, 60 – covering all common parity, striping, mirroring, and nested configurations.
- Device Capacity: Supports up to 32 drives per controller, allowing extensive storage arrays within a single MiniCard slot.
- Storage Interfaces: SAS‑3 (Serial Attached SCSI) and SATA III – compatible with both enterprise SSDs and high‑capacity HDDs.
- SSD Support: Full support for solid‑state drives, enabling low‑latency, high‑IOPS workloads.
Operating System Compatibility
The controller is engineered to work seamlessly across a broad spectrum of operating systems and virtualization platforms:
- Microsoft Windows Server: 2012, 2016
- Red Hat Enterprise Linux: 6.5, 7.0 or later
- SUSE Linux Enterprise Server: 12
- Virtualization Environments: VMware ESXi 6.0 and 6.5
Performance Highlights
The combination of a high‑bandwidth PCIe 3.1 interface, ample internal cache, and an efficient LSI processor family results in:
- Maximum Throughput: Up to 12 Gbit/s per lane, translating into sustained data rates well above 10 GB/s for large sequential workloads.
- Low Latency: The built‑in processor handles RAID calculations internally, reducing CPU overhead and minimizing access delays.
- Efficient Cache Utilization: 8 GB of dedicated memory allows aggressive read/write caching, improving performance for mixed I/O patterns.
Advanced Features
The H740P incorporates several enterprise‑grade features that enhance reliability and manageability:
- Hardware RAID Acceleration: Offloads all parity calculations to the controller, freeing host CPU resources.
- Hot‑Plug Support: Drives can be added or removed without shutting down the system, ensuring continuous availability.
- Power Management: Intelligent power‑saving modes for idle drives and cache, extending hardware lifespan.
- Integrated Diagnostics: Built‑in health monitoring tools provide real‑time status reports and predictive failure alerts.
Form Factor & Integration
The MiniCard design places the controller in a compact, low‑profile module that plugs directly into Dell servers. This architecture offers:
- Space Efficiency: Eliminates bulky backplane cards, freeing rack space for additional components.
- Thermal Management: Optimized airflow paths reduce heat buildup, maintaining stable operating temperatures.
- High‑density storage solutions with minimal physical footprint.
- Robust data protection through multiple RAID levels and hot‑plug capabilities.
- Seamless integration with existing Windows or Linux server stacks.
- Scalable performance for virtualization, database, and big‑data workloads.
Use Cases
The Dell Minicard PERC H740P is ideal for environments that demand:
Conclusion
The Dell Minicard PERC H740P RAID Controller delivers a powerful blend of speed, reliability, and flexibility. Its LSI processor core, generous cache, and broad OS support make it an excellent choice for enterprises seeking to maximize storage efficiency while maintaining operational continuity.

| Key Features | |
|
Built-in processor Indicates whether the product contains a built‑in central processing unit (CPU) that can execute instructions without requiring an external processor module. A value of "Yes" means the device has such a CPU; "No" means it does not.
|
Yes |
|
Channels quantity The total count of independent communication or signal pathways that a product can provide or receive, such as audio channels, video streams, data links, or radio frequencies. It indicates how many separate signals can be transmitted or processed simultaneously and is expressed as an integer.
|
8 channels |
|
Data transfer rate The maximum theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. It represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.
|
12 Gbit/s |
|
Internal memory The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.
|
