Smart Array

With the constant craze for technological advancement in the area of smart array controllers, it is no surprise that several companies are caught in a frenzy to improve the specifications of their storage drives.

A storage drive – as its name suggests – is the thing that provides your computer with that bit of extra storage space it needs to keep all your valuable data. With the help of an efficient Smart array controller, you can increase your capacity to hold more data for long periods of time.

At ALLHDD, we stock the finest range of Flash Backed Write Caches for smart arrays, dual port, gen10, and 12GB smart array controllers, RAID controllers, and Mezzanine cards. We are also committed to giving you the best service and information to help you pick the best smart array controller for your device.

About the Smart array controller

Helwett Packard was notably the first company to introduce RAID subsystems into the world of network servers, and their range of smart array controllers support RAID levels 0 through to 60.

The performance and data availability capacities of Hewlett Packard smart array controllers are always a work in progress. Nevertheless, the current capabilities of the device allow it to effortlessly maintain a high I/O throughput and remain reliable through the process.

Smart array controller features

Smart array controllers feature:

  • A competent multi-core and multi-processing engine:

The competent engine of the Smart array controller is in charge of the RAID system. As the central source of power, this device changes high-level read or write requests that are derived from an application into single bits of information that are required for the RAID array. Presently, the generation of smart array controllers we have made use of an implanted RAID-on-Chip (RoC) processor that operates at 600 MHz.

  • Customized connection settings and hardware tuning:

HPE smart array controllers manage errors by tuning the connection settings on each smart array controller to work in harmony with the PCIe bus and every other connected device. Through customized controller link settings, signaling margins are maximized and error rates are drastically reduced. The smart array utilizes a default configuration that helps it power up and function effectively, and can detect when to "step down" operating speeds to maintain a connection.

  • Advanced caching abilities:
  1. Read-ahead caching: Utilizing an adaptive read-ahead algorithm which notably improves I/O performance by anticipating data needs and cutting down wait time, the HPE smart array controller completely eliminates the issues that arise from fixed read-ahead schemes.
  2. Write-back caching: This feature allows the smooth running of applications to continue without having to wait for write operations to complete to the disk. Thanks to this feature, the smart array controller can round off write operations in microseconds instead of milliseconds.

Furthermore, the latest generation of smart array controllers can easily handle 256 MiB, 512 Mib, and 1 GiB cache modules, thus increasing the overall array performance by doubling the bandwidth for moving cache data to and from the storage system.
