When Nanoseconds matter, Dell delivers with Dell Processor Acceleration Technology


Dell Processor Acceleration Technology is a unique-to-Dell innovation that enables High Frequency Trading customers to increase their processor performance (frequency) from 13 to 31 percent while drastically reducing jitter in their applications. 

The demand for this technology was fueled by a need we were hearing from our algorithmic trading customers, who have a unique set of requirements for their business environments. Now, by using Dell Processor Acceleration Technology, these customers can get more performance out of their Dell solutions. In our external beta testing of this new capability, one IT Director in  Chicago at a large algorithmic trading firm reported an improvement in its application performance by  approximately 10 percent over the previous test unit – just by updating the existing server to the new firmware.

Our latest patent-pending enterprise advancement meets our customers’ requirements and unleashes the potential of current select PowerEdge 12th generation servers.

"The Dell Processor Acceleration Technology is a double win,” said Peter Harris, president of A-Team Group Americas. “It not only provides the kind of performance boost required to underpin more profitable algorithmic trading, but it is also fast and easy to install on existing server hardware, allowing trading firms to leverage it without costly and time consuming hardware upgrades and software code changes."

This dramatic improvement is surprisingly easy to implement and use. Any existing customer around the world with a PowerEdge R620, R720 or R720xd with the Intel E5-2690 processor can just download a BIOS update, at no additional cost, and apply it like any other standard Dell update, with no restrictions to the run time of the server or any reduction in the warranty. This solution is designed to work with all supported operating systems for PowerEdge 12th generation servers and also supports Dell’s agent-free OpenManage Essentials monitoring solutions. Customers may also pre-install other high performance components to the servers from the factory in tandem with this technology, including low latency network cards, high performance memory, and hot swappable front facing PCIe SSD storage for a truly complete low-latency solution from Dell.

This is another example of Dell customers inspiring our product innovation; we continue to enable meaningful customer results with solutions like Dell’s Processor Acceleration Technology.

    Hi. What BIOS version is that, 1.3.6 (released 11-Sep-2012) ?

  • CharlesN

    Piotr, according to this URL:


    …it is version 1.4.8 and came out on 18 Dec 2012.

    However, I downloaded the Release Notes R620-010408BIOS.txt and they have no mention of PAT.  It has this header, which says 1.4.8 but with an October Release Date:

    System:         Dell PowerEdge R620

    Version:        1.4.8

    Release Date:   10/26/2012

    So I don't know if there's a packaging problem, if it's "much ado about nothing" or if Dell went Stealth in the Release Note.

    We installed the BIOS and don't see any new knobs or buttons.

    It leaves me scratching my head; I would be happy for an explanation.

    I hope you caught the great webinar a couple days ago at low-latency.com about Dell PAT, it better explained what's happens with this BIOS.  Once you select the number of cores to boot with, the server comes up with them at the appropriate frequency.  Doesn't matter how many cores are active (i.e., doing work); the frequency won't change.

    It makes me wonder, though.  For folks who don't care about occasional latency spikes and who often are using only a couple of cores, they won't get the benefit of allowing the core they're using to ramp up even higher.  Install this BIOS and *BAM* — you won't get the highest possible turbo frequency.  Seems as though there ought to be a setting in the BIOS to enable this (for latency-sensitive folks) or disable it (for everyone else) — or at least mention it in the Release Notes.

    Hi Charles. Thanks for your comment. I spoke with the product team to get some answers for you – Dell Processor Acceleration Technology is available in R720 and R620 BIOS 1.4.8 when using iDRAC 1.30.30.  It is not enabled when the server is shipped from the factory, so Intel Turbo Boost works normally for customers who wish to have the maximum turbo frequency available for active cores.  The DPAT enablement option does not appear in the BIOS setup, rather it must be enabled using  a 1-to-many console, such as WSMAN or RACADM, or using a 1-to-1 console, such as DTK. Please let me know if you have any further questions!

  • CharlesN

    Thanks for the reply, Sarah, but I'm still in the dark.  Got syscfg version 4.2.6870 A00

    I assumed it would be an option to turbomode, but I get the following:

    C:Dellx64ToolkitTools>syscfg -h –turbomode

    When set to Enabled, the processor can operate in Turbo Boost Mode.

    Arguments : Enabled|Disabled

    Nothing else looks obvious to me; am I looking in the wrong place?
