General Information:

Enterprise RAID and Security With Accelerated NVMe® Performance

With the introduction of the new Adaptec® SmartRAID 4300 accelerator family, we deliver a fully featured and secure RAID-enabled, high-performance Software-Defined Storage (SDS) solution for NVMe deployments in server OEM, storage systems, data center and enterprise customers.

Leveraging Microchip's PCIe® storage controller as the underlying hardware to provide a supporting role for CPU o?oad and RAID acceleration the SmartRAID 4300 series separates the storage software stack to utilize the host PCIe infrastructure for more optimized data ?ows and connectivity. This new accelerator architecture overcomes bottlenecks inherent to traditional in-line storage solutions and enables the SmartRAID 4300 to deliver precise functionality and value when needed.

The SmartRAID 4300 maintains the enterprise-class features, functionality and hardware o?oad of our previous-generation in-line products, while delivering accelerated high performance that scales with the host, interconnect and CPU-attached NVMe endpoints. Management of the CPU-attached NVMe endpoints removes the dependencies that drive form factors, connector types and backplanes can create.

Our Trusted Platform support delivers a new level of compute and supply chain security based on a hardware root of trust that is aligned with the Open Compute Security Project.

Accelerated Enterprise NVMe RAID Storage

Our SmartRAID 4300 disaggregates our Smart Storage platform into separate software and hardware components for a new software-defined storage approach for NVMe RAID. With Smart Storage software operating on the host CPU, I/O data ?ows maximize performance with writes occurring directly to the NVMe endpoints, while parity-based redundancy (XOR) is o?oaded to the SmartRAID accelerator hardware.

Maximum Performance

With a software-defined approach to NVMe RAID storage, the performance boundaries shift back to the individual components such as CPU, interconnect and endpoints. Managing these components with an expanded infrastructure, the Smart Storage software is able to deliver a maximum-performance, robust enterprise-class RAID solution, while enabling the SmartRAID accelerator hardware to complement and accelerate the overall performance capabilities, as opposed to potentially becoming a bottleneck.

    About Microchip

    Learn more about SCSI/RAID Controllers

    What is a RAID controller?

    A RAID (redundant array of independent disks) combines multiple physical drives into one virtual storage device that offers more storage and, in most cases, fault tolerance so that data can be recovered even if one of the physical disks fails. A RAID controller is a hardware device or software program used to manage hard disk drives (HDDs) or solid-state drives (SSDs) in a computer or storage array so they work as a logical unit.

    A controller offers a level of abstraction between an operating system and the physical drives. A RAID controller presents groups to applications and operating systems as logical units for which data protection schemes can be defined. Because the controller has the ability to access multiple copies of data on multiple physical devices, it has the ability to improve performance and protect data in the event of a system crash. There are different levels of raid as well, typically the higher the number, the more redundancy your data will have. In some cases 1-2 hard drives can go down before you will be impacted! Another caveat with RAID is the ability to actually speed up your hard drive performance. The more drives you have in your array the more redundant and faster your I/O will become!



    In hardware-based RAID, a physical controller is used to manage the RAID array. The controller can take the form of a PCI or PCI Express (PCIe) card, which is designed to support a specific drive format such as SATA or SCSI. (Some RAID controllers can also be integrated with the motherboard.) A RAID controller may also be software-only, using the hardware resources of the host system. Software-based RAID generally provides similar functionality to hardware-based RAID, but its performance is typically less than that of the hardware versions.

    There was a problem with my credit card information (my fault) that delayed my order. CompSource's customer service took care of it by e-mail promptly. I am very satisfied with the company. rsb686
