Types of LSI SAS 3008

The LSI SAS 3008 is a 6GB-to-12GB SAS (Serial Attached SCSI) controller that is commonly used for high-performance storage systems. It comes in different models and configurations to suit various needs. Here are some of them:

• LSI SAS 3081EN

  The LSI SAS 3081EN is an OEM (Original Equipment Manufacturer) part that cannot be purchased directly by end users. It is an "Internal" card that connects directly to the drives in the storage subsystem. The "EN" indicates that it is an OEM part, which was initially intended for use by original equipment manufacturers of storage devices. It features 8 internal ports to which Serial Attached SCSI (SAS) drives can be connected.

• LSI SAS 3081E

  The LSI SAS 3081E is another internal Host Bus Adapter (HBA) that possesses 8 internal ports. This model is suitable for servers that need to connect a large number of SAS or SATA drives directly to the server. It helps in providing high-speed data transfer between the server and storage drives.

• LSI SAS 3008

  The LSI SAS 3008 contends for the category of outstanding value-to-performance ratio. It provides impressive throughput capabilities and is beneficial for high-performance storage tasks such as data storage, transaction processing, and virtualization. The SAS 3008 dual core has the capability to connect to 128 SAS or SATA devices.

• LSI SAS 3088E

  LSI SAS 3088 E is a multi-channel controller that can connect to a large number of SATA or SAS drives. It has 8 ports and works efficiently in storage-intensive applications such as databases, data warehousing, and virtualization.

  This model has the capability of connecting 6GB to 12GB SAS to serve different types of workloads. It is commonly used for high capacity and high performance computing environments.

Function and feature of lsi sas3008

The LSI SAS 3008 is an 8-port model designed for low-to-medium-density external RAID applications. The chip has multiple features, which include the following:

• Dual-Core CPUs

  The LSI SAS 3008 chip has two independent cores of varying sizes. Both cores run the same firmware and driver, with one core designated as the primary core. During normal operations, the primary core supervises the second core, referred to as the auxiliary core. When a core fails, the second one takes over, ensuring reliable operation. Both CPUs have their own instruction sets, memory controller, and interconnects between core components.

• Single Chip Architecture

  System implementers must integrate fewer components due to the single-chip architecture of the SAS 3008. It combines a PCIe interface, an FC interface, and multiple SAS ports in a single package. This reduces the need for additional chips when building a new system and increases its reliability. Multiple functionalities sharing the same chip with interconnects optimized for low latency helps reduce overall system latency.

• LSI's Cache Management Technology (CMT)

  Cache management technology protects the stored data in a volatile memory (cache) against sudden power loss. Whenever there is a sudden power outage, the cache holds the data in the cache and transfers them to the hard disk as long as the battery is functional. The technology uses battery-backed, low-power DRAM with a supercapacitor to store data during a power loss.

• Large Queue Depths

  Large queue depths allow a diversified workload on the same storage adapter. It enables administrators to mix different workloads over time. The SAS 3008 gives system and storage area network (SAN) managers pause on their previous configurations on path management and queue depths.

• RoHS Compliance

  The LSI SAS 3008 is compliant with the Restriction of Hazardous Substances regulations. It contains restricted substances in quantities greater than RoHS approved levels. Compliance increases the chip's compatibility with manufacturers looking to produce green products.

• Simplified and Scalable Architecture

  Having all its integration in a single chip, the LSI SAS 3008 has a simplified and scalable architecture. It has reduced overall latency, which improves system performance. The chip offers a reliable solution for SAS and SATA connectivity with enhanced scalability.

Applications of LSI SAS3008

The LSI SAS 3008 chip can be applied in various scenarios where high-speed data transfer and storage connectivity are crucial. Here are some common use cases:

• Data centers: In data centers, storage controllers like the SAS 3008 support multiple hard drives. This helps servers quickly retrieve and store data, which is important for services like cloud computing and streaming videos online.
• Enterprise servers: Servers that run programs for businesses use these controllers to connect to large hard drive packs. This ensures they reliably save important information that servers need for tasks such as backup and recovery.
• High-performance computing (HPC): HPC systems tackle difficult problems quickly. They need fast access to data, which the SAS 3008 helps with. It can connect many drives to enable fast data processing.
• Database storage: Databases hold massive amounts of data. Controllers like the SAS 3008 ensure databases can work well by enabling quick data input and output operations, which is important for business analytics and transactional systems.
• Virtualization environments: In virtualization, using the right controller is key to efficiently allocating virtual disks to multiple virtual machines from redundant arrays of independent disks (RAID) configurations and dynamically allocating storage to virtual machines.
• Surveillance systems: Surveillance systems need reliable and fast storage to keep track of video feeds. The SAS 3008 provides this by allowing controllers to connect many hard drives where video clips can be safely stored.

How to choose a sas3008

When buying the LSI SAS 3008, it is crucial to examine and make sure it satisfies particular requirements.

• Compatibility:

  Check that the LSI SAS 3008 is compatible with the current system before making a purchase. It works with various motherboards, but confirming compatibility with the chipsets and PCIe lanes is a good idea. Ensure the firmware of the host system is up to date to prevent problems.

• Applications and Port Count:

  The application and storage need are the main drivers behind purchasing the SAS card. The total number of drives that can be connected to it determines the port count. Choose an HBA with 8 ports or more if planning to set up fewer storage devices. However, opt for one with an expandable architecture if planning to establish a larger cluster or need more than 8 HBAs.

• Bandwidth:

  High data transfer needs require a card with excellent bandwidth. Measure the I/O operations and data throughput required for the application. Then, choose a card that can handle those needs. To put it another way, one should not opt for a low-card bandwidth if the daily activities involve migrating petabytes of data or streaming 4K video.

• Data Access Mode:

  Access requirements should be fully understood before making a purchase. This is important because the mode of access will determine the choice of card interface. For instance, cards meant for direct attached storage should operate in non-RAID mode, while those for shared storage should be in RAID mode.

• Form Factor:

  Be sure to check the server chassis before buying the card to know the card form factor supported. Is it a full-height, low-profile cards, or both? That should be known in advance so the right card can be selected to avoid wasting resources and time returning it.

• Power and Cooling Requirements:

  Evaluate the power needs of the SAS 3008. The standard low-profile cards consume no more than 25W. But if the plan is to work with a card that has more ports and supports better features, it may require more power. Ensure adequate cooling is provided to the system. The card should also have enough airflow to prevent overheating.

• Budget and Vendor Reputation:

  Finally, set a budget for the purchase and research the vendors selling SAS cards. Aim for a card priced within the budget but with excellent performance. Be sure to check vendor reviews to make sure they are known for reliable cards and good customer support before and after sales.
