I. RAID Controller Cards: The Core Defence Line for Enterprise Data Security

The Broadcom MegaRAID series of RAID controller cards represents the most widely deployed and highly recognised RAID data protection architecture globally. With years of deep expertise in the enterprise storage sector and having undergone multiple generations of technological evolution, these cards are fully compatible with various Direct-Attached Storage (DAS) environments. They balance data security, transmission performance and deployment flexibility, perfectly meeting the data storage and protection requirements of core enterprise operations.

Core Technologies and Product Advantages

1. Full Tri-Mode Compatibility, Unlimited Deployment: Leveraging Broadcom’s exclusive Tri-Mode SerDes technology, a single card simultaneously supports NVMe (PCIe), SAS and SATA storage media. Various storage devices—including mechanical hard drives, solid-state drives, U.2 drives and M.2 drives—can be seamlessly integrated. This enables mixed deployment of new and legacy storage devices without hardware replacement, significantly reducing storage architecture upgrade costs.

2. Unrivalled performance, suitable for high-load scenarios: Mainstream models are fully equipped with PCIe 4.0 buses, whilst certain high-end models support the OCP 3.0 specification. With transmission bandwidth doubled compared to the previous generation, they can easily handle business scenarios requiring high bandwidth and low latency, such as databases, cloud computing and big data analysis; Support for the full range of RAID levels (0/1/10/5/50/6/60) meets configuration requirements for varying levels of data security and read/write performance.

3. Robust data protection and maximum stability: Features a dedicated RAID-on-Chip (RoC) chip that performs array operations independently, without utilising server CPU resources; incorporates cache protection technology to fully preserve cached data in the event of a power failure, preventing service interruptions and data corruption; A single card can connect up to 1,024 SAS/SATA devices and 32 NVMe devices, balancing scalability and reliability, with an MTBF exceeding 3 million hours to ensure 24/7 uninterrupted operation.

4. Simplified operations and maintenance, reducing management costs: Supports the LSI Storage Authority (LSA) graphical management tool and StorCLI command-line tool, with UEFI visual configuration support. Enables real-time monitoring of hard drive status and array operation, facilitating rapid array deployment, fault diagnosis and parameter tuning. Compatible with all major operating systems including Windows, Linux and VMware, with an extremely low operational threshold.

Suitable Scenarios

Enterprise-class servers, core storage for small and medium-sized enterprises, standard data centre storage deployments, and industries with stringent data security requirements such as finance, healthcare and government. It is suitable for building entry-level storage architectures as well as meeting the high-performance storage demands of high-end servers.

II. NVMe Switch Adapters: Unlocking the Ultimate Potential of High-Speed Flash Storage

As NVMe SSDs become the mainstream choice for high-speed enterprise storage, traditional storage interconnect solutions struggle to meet the demands of multi-drive configurations, high concurrency and low-latency data transfer. Broadcom’s NVMe switch adapters are built on a PEX switch architecture, specifically designed for enterprise-grade NVMe SSD expansion and interconnectivity. They break through PCIe channel limitations to maximise the performance of flash storage.

Core Technologies and Product Advantages

1. Native NVMe Interconnect, Zero Performance Loss: Utilising a switch-based architecture, NVMe SSDs are natively mapped to the host system without the need for additional protocol conversion. The low-latency and high-bandwidth characteristics of the NVMe protocol are preserved throughout, perfectly supporting the connection of NVMe drives in x1, x2, and x4 configurations. This fully leverages the read/write speeds of flash drives, significantly reducing latency compared to traditional adapter solutions.

2. High-Density Expansion, Enhanced Storage Density: A single adapter enables multi-port NVMe device expansion, allowing servers and storage devices to connect more high-speed NVMe SSDs within limited space. This significantly boosts overall storage density, catering to scenarios such as cloud computing, edge computing, and AI inference that demand both storage capacity and performance, whilst resolving channel bottlenecks in high-density deployments.

3. Enterprise-grade management for hassle-free operations: Supports fully managed operation with comprehensive device monitoring, fault alerting and bandwidth allocation capabilities. Compatible with host native NVMe drivers and operating systems, eliminating the need for additional dedicated drivers and ensuring convenient deployment. Supports hot-swap functionality, allowing for drive replacement and capacity expansion without downtime, thereby ensuring business continuity.

4. Flexible Adaptability, Compatibility with Diverse Architectures: Compatible with standard PCIe slots, it supports various hardware form factors including rack-mounted servers, blade servers and high-density storage enclosures. It can be deployed as a high-speed array in conjunction with RAID controller cards, or function independently as an NVMe expansion solution, making it suitable for diverse architectures such as hyperscale data centres and distributed storage systems.

Suitable Scenarios

Business scenarios demanding extreme storage read/write speeds and low latency, such as hyperscale data centres, AI computing clusters, cloud computing platforms, high-definition video rendering, and high-frequency trading systems, as well as storage expansion scenarios requiring high-density deployment of NVMe SSDs.

III. SAS Expanders: Bridging the Gap for Massive Storage Expansion

Faced with massive data storage demands, the number of storage interfaces on a single controller is inherently limited. Broadcom SAS expanders are specifically designed for large-scale storage capacity expansion, serving as the core hub connecting servers, RAID controllers and massive storage devices. Leveraging the mature SAS protocol, they enable low-cost, highly stable deployment of massive storage.

Core Technologies and Product Advantages

1. Massive Capacity Expansion to Meet Massive Storage Demands: Supports 12Gb/s SAS high-speed transmission and is backwards compatible with 6Gb/s SATA devices. A single expander can cascade dozens to hundreds of storage devices, enabling the effortless construction of petabyte-scale storage clusters. It perfectly addresses high-capacity data storage requirements such as big data storage, archival storage and surveillance data storage.

2. DataBolt Bandwidth Aggregation Technology for Enhanced Transfer Efficiency: Equipped with Broadcom’s proprietary DataBolt technology, it aggregates the bandwidth of multiple SATA storage devices, compensating for the limited transfer rates of SATA devices and improving the overall read/write efficiency of the storage system. This achieves optimal performance in mixed SAS and SATA deployments, balancing cost and performance.

3. End-to-end stability for worry-free data transmission: Supports multi-path redundancy and automatic failover, preventing a single point of failure from paralysing the entire storage system; features a comprehensive thermal management design and electrical protection, suitable for 24/7 data centre environments; compatible with various storage enclosures and servers, with compatibility and stability validated across a wide range of global scenarios.

4. Flexible cascading and scalable architecture: Supports stacked and cascaded deployment, allowing storage capacity to be expanded incrementally in line with enterprise data growth requirements without the need to reconfigure the entire storage architecture; supports hot-swapping and automatic device recognition, making expansion and maintenance operations simple and requiring no downtime for debugging, thereby meeting the needs for elastic upgrades in enterprise storage architectures.

Suitable Scenarios

Ideal for scenarios requiring large-scale, low-cost storage capacity expansion, such as massive data archiving, surveillance video storage, big data analytics platforms, distributed storage clusters, enterprise private clouds and media resource libraries. It serves as a core component for enterprises looking to build low-cost, high-capacity storage systems.
