Need help?Do you have a question about the Supermicro AOC-S3008L-L8i and is the answer not in the manual?
The Supermicro AOC-S3008L-L8i is a high-performance internal SAS RAID Adapter designed to meet the demanding storage needs of high-end server platforms. This add-on card serves as a crucial component for system integrators, IT professionals, and knowledgeable end users looking to enhance their server's storage capabilities and overall performance. Its primary function is to provide robust RAID support, enabling efficient data management and protection within a server environment.
At its core, the AOC-S3008L-L8i leverages the Avago 3008 SAS controller, a powerful component that facilitates advanced storage operations. This controller is integral to the card's ability to offer optimal RAID performance, ensuring data integrity and accessibility. The card supports various RAID configurations, specifically RAID 0, 1, and 10, which provide different levels of data striping, mirroring, and parity for performance and redundancy. RAID 0 offers enhanced performance through data striping, RAID 1 provides data redundancy through mirroring, and RAID 10 combines both for improved performance and fault tolerance. This flexibility allows users to choose the RAID level that best suits their specific application requirements, whether it's maximizing speed, ensuring data safety, or a balance of both.
The add-on card is equipped with eight internal SAS3 ports, which are essential for connecting to storage devices. These ports are designed to support SAS 3.0 connections, ensuring high-speed data transfer rates. The card utilizes two mini SAS HD cabling for these connections, providing a compact and efficient way to link multiple drives. The support for SAS 3.0, along with backward compatibility for SAS 6.0 Gb/s and 3.0 Gb/s, as well as SATA data transfer rates, makes it versatile for integrating with a wide range of storage devices. This broad compatibility ensures that users can connect various types of hard drives and solid-state drives, making the card adaptable to different storage infrastructures.
One of the key usage features of the AOC-S3008L-L8i is its host interface. It is designed with a standard PCI-E Gen3 x8 lanes host interface, which provides increased I/O bandwidth. This high-speed interface is crucial for ensuring that data can be transferred quickly and efficiently between the storage devices and the server's CPU, minimizing bottlenecks and maximizing application performance. The card is also capable of automatic negotiation for PCI-E link widths (1x, 2x, and 3x), which allows it to adapt to different slot configurations and optimize its performance within the server.
The card incorporates an onboard hardware I/O processor operating at 1.2 GHz. This dedicated processor offloads storage management tasks from the main CPU, further enhancing overall system performance. By handling I/O operations independently, the processor ensures that the server's CPU can focus on other critical tasks, leading to a more responsive and efficient system. Additionally, the card supports software RAID for up to 63 devices, providing extensive scalability for large storage deployments. This feature is particularly beneficial for environments that require a significant number of drives to meet their data storage needs.
For system management and monitoring, the AOC-S3008L-L8i includes several useful features. It has a System Management Bus (SMB) header (J9), which is used to monitor critical parameters on the add-on card. This allows administrators to keep track of the card's status and performance, ensuring stable operation. The card also features a UART0 header (J5), which provides serial communications support. This can be used for debugging, configuration, or connecting to peripheral devices, offering flexibility for advanced users and troubleshooting.
A visual indicator for the card's operational status is the System Heartbeat LED. This LED is located below the SMB header and provides a quick visual cue about the card's health. When the LED is blinking green, it indicates that the system is functioning normally. If the LED is off or red, it signals that the system is disabled or has failed, prompting immediate attention from the user. This simple yet effective indicator helps in quickly diagnosing potential issues without needing to access complex software interfaces.
In terms of physical design, the AOC-S3008L-L8i is a low-profile PCI-E card, making it suitable for a wide range of server chassis, including those with limited space. The card also features an enlarged venting hole mounting bracket, which is designed to improve airflow and aid in heat dissipation. Effective thermal management is crucial for the longevity and stable operation of electronic components, especially in high-performance server environments. This design consideration helps maintain optimal operating temperatures, contributing to the card's reliability.
The card supports various storage protocols, including SSP (SAS Serial Protocol), SMP (SAS Management Protocol), STP (SATA Tunneled Protocol), and SATA products. This comprehensive support ensures compatibility with a broad ecosystem of storage devices and management tools. Furthermore, it offers zoning capability with SAS2 expanders, which allows for flexible configuration and management of connected storage devices, enabling more complex storage architectures.
For software management, the AOC-S3008L-L8i supports MegaRAID Storage Manager software. This software provides a user-friendly interface for configuring, monitoring, and managing RAID arrays and connected storage devices. It simplifies complex storage tasks, making it easier for administrators to maintain their storage infrastructure.
Regarding maintenance and operational considerations, the manual emphasizes the importance of proper handling due to the card being a static-sensitive device. Electrostatic Discharge (ESD) can cause significant damage to electronic components, so precautions such as using a grounded wrist strap, touching grounded metal objects, and handling the card by its edges are recommended. When not in use, the card should be stored in antistatic bags to protect it from ESD. For grounding purposes, it is important to ensure that the system chassis provides excellent conductivity between the power supply, the case, the mounting fasteners, and the add-on card.
The installation process is straightforward but requires adherence to specific steps to ensure proper setup and prevent damage. Before installation, users are advised to power down the system, remove the power cord, and familiarize themselves with the server, motherboard, and chassis documentation. It is also recommended to confirm that the operating system includes the latest updates and hotfixes to ensure compatibility and optimal performance. During installation, the add-on card is positioned directly over the PCI connector and gently pushed down until it slides into place. Securing the card to the chassis and attaching necessary external cables are also part of the process.
The AOC-S3008L-L8i is designed for a wide range of operating systems, including Windows Server 2012, 2008, RedHat Enterprise Linux, and SUSE Linux. This broad OS support ensures that the card can be integrated into various server environments without compatibility issues. The card operates within a temperature range of 0°C to 55°C, making it suitable for typical data center environments. Its power requirement is 18W, which should be considered when planning the server's power budget.
