This Storage Intelligence (StorInt™) dispatch covers Storage Performance Council (SPC) results. There have been five new SPC-1 v3 submissions, two from Huawei, their OceanStor 18800F v5 and the OceanStor 18500 v5, the Fujitsu ETERNUS DX600 S4, the Lenovo ThinkSystem DS6200 and the MacroSAN MS2500G2-25E. Once again there have been no new SPC-2 submissions. Many SPC-1 top ten charts have changes.
We begin our discussion with top ten SPC-1 measured IOPS™ performance in Figure 1.
In Figure 1, we can see both new Huawei OceanStor systems did well. The OceanStor 18800F v5 came in as the new #1 with over 6M IOPS and their OceanStor 18500 v5 came in at new #3 with over 4.8M IOPS. The fact that 5 of the top ten SPC-1 IOPS ranked systems are various versions of Huawei storage says that they are focused on high IO rates.
Huawei seems able to do so well in maximum IOPS because OceanStor is a clustered storage system using 16 controllers or 8 nodes (believe PCIe switched bus between them) with lots of SSDs. The #1 and #3 above had 384 and 288 SSDs respectively. Yes these were 900GB SSDs but with almost 300 and 400 SSDs you can generate a lot of IOPS if you have the horsepower to handle it, and 16 controllers with switched PCIe bus between them seems to be able to supply all the horsepower it needs.
One would think cost would be a major concern for Huawei systems but we have two views on storage economics. In Figure 2 we present the SPC-1 Price-Performance™ ($/IOPS) metric.
In Figure 2, the new Lenovo ThinkSystem DS6200 came in #2 with a Price-Performance of $0.09/IOP. The new Lenovo storage was a relatively small system with only 12 400GB SSDs, 2.3TB of ASU capacity and cost around $16.8K. But even with that small a system was able to generate over 180K IOPS. Most of the storage system on the $/IOPS top ten these days are relatively smaller systems. It speaks to me of some bias in this metric.
In Figure 3 we show our version of the economic performance of storage systems with a SCI computed IO/sec/GB metric.
In Figure 3, we see that Huawei has done even better than their showing in top IOPS. With 7 out of the top 10 with their two new OceanStor 18800F v5 and 18500 v5 storage coming it at #1 and #2, respectively. Perhaps our metric has a bias as well, although we are not sure what that is.
But it’s interesting to see that the FusionStack FusionStor SF6000 shows up well on both measures of inexpensive performance
Finally, in Figure 4 we show SPC-1 measured LRT metric.
In Figure 4, the new Lenovo ThinkSystem DS6200 came in at the new #7 with an LRT of 0.017 msec. We are going to have to change the scale from msec. to msec soon, as every systems in the top ten LRT is under 200 msec. Unclear how the new ThinkSystem managed to do so well here but it was using a 12Gbs SAS connection to the host and SAS connected 400GB SSDs.
It’s pretty impressive to see how well Huawei’s new OceanStor systems placed in IOPS and IOPS/$/GB but their architecture probably has something to do with it. We wrote a recent blog post on Huawei’s OceanStor architecture presentation at Storage Field Day 15 (see our RayOnStorage post on Huawei presents OceanStor architecture at SFD15) which may explain more of what they are doing, if interested.
It’s unfortunate that the new Fujitsu ETERNUS DX600 S4 and MacroSAN MS2500G2-25Er didn’t crack into any of our SPC-1 top ten status charts. But storage performance is heating up of late and it’s getting harder to place well..
