Understanding LSI LogicDefinition of LSI Logic
LSI Logic, a renowned technology company, has a history of developing advanced solutions for storage and networking. The LSI00194 9211-8I RAID controller is a testament to their commitment to delivering high-performance hardware for data storage.
RAID Controller Basics
A RAID (Redundant Array of Independent Disks) controller is a crucial component in a storage system. It manages multiple disk drives to enhance performance, reliability, or a combination of both. The LSI00194 is specifically designed for SAS (Serial-Attached SCSI) drives, a technology known for its speed and reliability.
Key Features6 Gigabytes (GB) Data Transfer Rate
- The LSI00194 boasts a 6GB/s data transfer rate, ensuring swift and efficient data movement within the storage system. This feature is particularly valuable in scenarios where quick access to data is critical, such as in enterprise environments or data-intensive applications.
8 Ports for Enhanced Connectivity
- With 8 internal ports, the LSI00194 offers ample connectivity for SAS drives. This is advantageous in setups requiring a large number of drives, providing flexibility in configuring RAID arrays for different purposes, from performance-focused RAID 0 to redundancy-oriented RAID 1.
PCI Express (PCIE) X8 Interface
- The RAID controller utilizes the PCIE X8 interface, a high-speed connection standard commonly found in modern computers. This ensures optimal communication between the RAID controller and the motherboard, preventing bottlenecks and maximizing overall system performance.
Serial-Attached SCSI (SAS) Technology
- SAS technology combines the benefits of SCSI (Small Computer System Interface) and serial technology, offering superior performance and scalability. The LSI00194’s compatibility with SAS drives contributes to its ability to handle demanding workloads.

It has a PCI-E x8 interface and supports SAS and SATA hard drives, making it compatible with a wide range of storage devices.
- In terms of performance, the LSI00194 is capable of delivering high data transfer rates and low latency, making it ideal for use in high-performance computing and data-intensive applications. It also supports RAID levels 0, 1, 5, and 6, which allows for data protection and redundancy.
- In terms of scalability, the LSI00194 supports up to 8 internal SAS or SATA ports, which allows for the connection of multiple storage devices. This allows for the expansion of storage capacity as needed, making it ideal for use in growing businesses or organizations.
RAID support and configuration options
The LSI00194 LSI Logic 9211-8I 6GB 8 Ports Internal PCI-E X8 SAS Raid Controller supports a variety of RAID configurations, including:
- RAID 0 (Striping) – Data is split across multiple drives, resulting in increased performance and improved read/write speeds.
- RAID 1 (Mirroring) – Data is duplicated across multiple drives, providing redundancy and data protection in case of a drive failure.
- RAID 5 (Parity) – Data is striped across multiple drives with parity information stored on one drive, providing data protection in case of a single drive failure.
- RAID 6 (Dual-Parity) – Similar to RAID 5, but with two drives dedicated to storing parity information, providing even greater data protection in case of multiple drive failures.
- RAID 10 (Striping and Mirroring) – A combination of RAID 0 and RAID 1, data is striped across multiple drives and mirrored for redundancy and data protection.
- RAID 50 (Parity and Striping) – A combination of RAID 5 and RAID 0, data is striped across multiple drives with parity information stored on one drive, providing improved performance and data protection in case of a single drive failure.
- RAID 60 (Dual-Parity and Striping) – A combination of RAID 6 and RAID 0, data is striped across multiple drives with two drives dedicated to storing parity information, providing improved performance and data protection in case of multiple drive failures.
The controller also supports JBOD (Just a Bunch of Disks) mode, which allows for multiple drives to be used independently without any RAID configuration.
