Supermicro's Latest Twin

We got a sneak peak at the Supermicro's brand new Twin 2U server: the SYS-6027TR-D71FRF. The 2U chassis has two dual Xeon E5 based servers inside that are fed by two fully redundant 1280W PSUs (at 180-230V, 1000W at 100-140V).

The two servers are held in place using screwless clips.

You get the density of a 1U server without needing four PSUs for redundancy and without the very power hungry 40 mm fans. Indeed, using only 2 PSUs and 80 mm fans should save quite a bit of power compared to 2 1U servers. Last time we measured, the Twin servers consumed 6% less power than the best 1U servers on the market.

At the same time, the expansion capabilities are better: you get two full height and one half height PCIe 3.0 (!) x16 (x8 electrical) slots. The only disadvantage is that you only get 4 DIMM slots per CPU, which generally limits each server to about 128 GB of RAM (8 x 16 GB) unless you go with expensive 32 GB LR-DIMMS for a total of 256 GB. Therefore this server is probably better for HPC workloads than for memory intensive virtualization and database applications.

This new Twin server also features FDR InfiniBand interconnect technology, good for 56Gb/s (!) low latency network connections with an X4 cable. This should work especially well in tandem with Intel Data Direct I/O technology, where packets are directly transferred into the Last Level Cache (LLC) instead of being DMAed to the memory. This is something we'll be investigating in a later article.

    From the 'article' .....

    'The Opteron might also have a role in the low end, price sensitive HPC market, where it still performs very well. It won't have much of chance in the high end clustered one as Intel has the faster and more power efficient PCIe interface'

    Well, if that's the case, why exactly would AMD be scoring so many design wins with Interlagos. Including this one ...

    U think those guys at Cray were going for low performance ? In fact, seems like AMD has being rather cleaning up in the HPC market since the arrival of Interlagos. And the markets have picked up on it, AMD stock is thru the roof since the start of the year. Or just see how many Intel processors occupy the the top 10 supercomputers on the planet. Nuff said ...

    Johan, where in the specs where you have this line:
    Transistors (Billion) 2,26 2x 1,2 2x 904 1,17

    I sure hope that 2x 904 (Billion) is a typo... otherwise AMD has some serious explaining to do. ;)

    Should be 2x ,904 (I think? Would be 2x .904 for me, I assume you follow the same rules...)

    Hi Johan,
    Always look forward to reading your server reviews at AT, but no SAPS benchmarks this time?

    For maximum VMware performance on Opteron Interlagos cpu under VMWARE it's better to disable C1E and enable, where available, HPC mode.

    I found myself on a fresh installation of ESXi 5.0 on Dell R715 that leaving C1E enable literally crippled vm performance.

    I'm not sure I would recommend using iray as a reliable benchmark renderer in 3ds max. It is not a self configuring mental ray, but an unbiased renderer which behaves fairly differently to mental ray, and most other renderers such as vray, final render and brazil. It is comparible to maxwell and fryrender, but is very new compared to those two longer established unbiased render engines. It also attempts to use the gpu to add to its calculations as well - which could significantly skew results.

    Using mental ray or vray might well give you quite a different result, and besides I don't think iray is widely used in the industry.

    This. The results of iray are mostly dependent on the GPU. The lack of proper scaling certainly isn't due to Amdahl's law. Just use mentalray with small enough render buckets and you can easily satisfy 64+ threads.

    Also, due to the limitations of iray, it can (at this moment) only be used in about 1-3% of real world scenarios.

    Please, for all the people that care about these benchmarks, use mentalray and/or vray.

    Otherwise, it's a brilliant article.

    You've put that Interlagos has 4x2MB L2, but that would only be true for Valencia; Interlagos is 8x2MB. Reply

    Hi There,
    Thanks for an excellent article. With regards to the rendering benchmarks, would you consider using VRay as a rendering engine? It's fast becoming industry standard, is compatible with all the big hitters (Max, Maya, Softimage etc), is cross platform, and I believe, is incredibly well coded to scale with cores.
    It's also incredibly popular, not something you could say about iRay right now.
