We return now to Storage Performance Council (SPC) results*. There have been four new SPC-1submissions, the Huawei OceanStor™ S5500T, Huawei OceanStor S2600T, Huawei OceanStor S5800T and IBM DCS3700 with performance modules. Also we have two new SPC-2 submissions, the IBM DCS3700 with performance modules and Fujitsu ETERNUS DX8700 S2. Although most of the SPC-1 submissions didn’t make many of the top 10 charts the new SPC-2 submissions were more interesting.
By the way, Huawei has resubmitted all the old Huawei Symantec OceanSpace SPC-1 results under their Huawei OceanStor brand. Now there’s much less confusion.
We start our discussion with the top 10 composite MB/sec or MPBS™ throughput performance for SPC-2.
Higher is better on the MBPS chart. The Fujitsu ETERNUS DX8700 S2 came in as the new number 1 with over 16GB/sec in composite throughput. The fact that it was able to perform this well with under 800-10Krpm 300GB disk drives is pretty interesting. It turns out its superior composite MBPS performance was due to its exceptional large database query (LDQ) performance (see below).
Another way to view composite MBPS performance is to separate out the three workloads, which we show below.
Here we can see that the Fujitsu DX8700 S2 did exceptionally well in large database query (LDQ) (~22GB/sec) which brought its composite score up to beat the previous winner the IBM DS8870. There were a couple of systems that did better than the DX8700 S2 in video-on-demand (VoD) and one in large file processing (LFP) performance but none came even close to its LDQ numbers.
We can only guess that Fujitsu’s LDQ results are due to superior database query caching and perhaps better backend bandwidth/balance. But without looking further into Fujitsu’s DX8700 S2 submission details it’s hard to come up with any other rational as to why it did so well in LDQ as compared to the rest of the top 10.
Next we turn to storage MBPS/drive
Recall that last time SGI’s version of NetApp’s E-series system came in as the new #1 system. Well the IBM DCS3700 (which although not mentioned looks like another NetApp E-series system) came in as the new #2 just slightly worse with both providing ~67MBPS/drive. It turns out that the SGI system used 146GB drives and the IBM system used 300GB drives, which might explain its slightly worse, #2 ranking.
None of our primary SPC-1 metric Top 10 charts (IOPS, LRT, $/IOPS) had any change so we turn now to the SPC-1 IOPS/drive results.
Here we can see all of the new submissions the Huawei OceanStor S2600T, S5800T, and S5500T coming in at #4, 5 & 8 as well as the new IBM DCS3700 (NetApp E-series system) that came in at #7. Huawei seems to do very well on this metric with 6 of the top 10 positions. But once again both the SGI InfiniteStorage 5500-SP and the IBM DCS3700 had similar E-series configurations with the SGI using 146GB drives and the IBM using 300GB drives and came in almost as a tie, with ~359 IOPS/drive.
It’s good to see new SPC-1 and SPC-2 data in our top 10 charts. Fujitsu’s latest SPC-2 MBPS results deserve further study to figure out how they performed on LDQ so well.
Also the NetApp E-series products continue to do well in both SPC-1 and SPC-2 results on a per drive basis. Unclear where this comes from but given its good results in both SPC-1 and SPC-2 it indicates optimized IO processing and/or optimized drive processing code more than caching effectiveness.
We keep hearing rumors about hybrid and all flash arrays submitting SPC-1 results but have yet to see any results online. Which just goes to show that raw IOmeter speed is not the same as SPC-1 IOPS or SPC-2 MPBS.
As always, suggestions on how to improve any of our performance analyses are welcomed. Additionally, if you are interested in more block performance details, we now provide a fuller version (top 30 results) of all these charts and a set of new ChampionsCharts™ for SAN storage in our recently updated (May 2019) SAN Storage Buying Guide available from our website.
