This Storage Intelligence (StorInt™) dispatch covers Storage Performance Council (SPC) results[1]. Since our last report,  two quarters ago there have been 4 new SPC-1 v3 submissions, three from Fujitsu, ETERNUS DX900 S5, AF150 S3 and the AF650 S3 and one from Telecommunications Technology Association (TTA) Gluesys AnyStor-700EK. All these submissions were AFA. There were also 4 new SPC-2 submissions of the same systems. We will cover SPC-2 results in a future performance report. This report will focus on these systems SPC-1 results.

SPC-1 results

We begin our discussion with top 10 SPC-1 LRT™ performance in Figure 1.

Figure 1 Top 10 SPC-1 LRT 

The new TTA Gluesys AnyStor-700EK came in as our new #8 with ~135 µsecs[2]and the new Fujitsu ETERNUS DX900 S5 came in an #10. The Gluesys storage used 24 480GB SAS/SATA SSDs and 100Gbps InfiniBand networking. Recall, that LRT is measured at 10% of peak workload, or 31K IOPs not a heavy load these days so that may have helped them to do so well. Nonetheless, ~135 µsecs is pretty damn fast for in my view. 

The Fujitsu ETERNUS DX900 S5 used 192 960GB SAS/SATA SSDs and was measured at 160K IOPs. This is a more substantial workload and subsequently seems more realistic. Also 151 µsecs is also pretty damn fast, especially for standard 16Gbps FC interfaces.  

In Figure 2 we present SPC-1 Price-Performance™ metric, the top ten $/K-IOPS.[3]

Figure 2 SPC-1 Top 10 SPC-1 Price-Performance results

The new Gluesys AnyStor-700EK came in as our new #2 with ~$84.0/ K-IOP. They had a relatively small configuration 4TB ASU capacity and only had 1 InfiniBand connection, which made their system inexpensive for the 310.5K IOPs they were able to achieve. 

The Fujitsu ETERNUS AF150 S3 came in at our new #3 with $89.40/K-IOP. The AF150 was also a smaller system which only had 5.5TB of RAID 1 ASU capacity and 2 FC ports which led to another inexpensive system for the 280K IOPS they were able to achieve. 

Next we display a SCI derived bubble chart which shows the types of IOPS and LRT attainable for AFA and disk only systems in the SPC-1 results. 

Figure 3 SCI derived chart IOPS X LRT with bubble size=$/GB for systems

As we can see in Figure 3 there are definitely many AFA systems with LRT below 1msec and most disk only systems range in LRT from 1.3 to 3msec in SPC-1 results. It’s interesting to note that there are a gaggle of AFA, relatively inexpensive (in $/GB) systems capable of 800K IOPs or more and there is a wide cost ($/GB) range of AFA systems that are capable of < 500µsec LRTs. 

Significance

It’s great to see new SPC-1 and SPC-2 submissions especially when they rank in some of our top ten charts. It’s interesting to see a relatively inexpensive system achieve top 10 LRT results but it’s unclear the advantage that came with InfiniBand host interface. There aren’t many InfiniBand results in SPC-1 data (only 3 TTA systems in our top 30 LRT results use InfiniBand). 

I know saving SPC-2 results is unkind but given the paucity of new SPC submissions or for that matter any performance benchmark results in recent quarters I felt it best to spread them out across two reports. 

As always, suggestions on how to improve any of our performance analyses are welcomed.

[2] Summary metrics for the TTA Gluesys AnyStor-700EK were not available at press time but we were able to interpolate an approximate LRT of ~135µsecs, from a graph in the Full Disclosure Report. We may be off by +/- 5µsecs which could change its rankings but it would still be somewhere between #7 to #9 in LRT. 

[3] Unclear when SPC-1 stopped using $/IOPS and went to $/K-IOPS but it makes sense and I will start using it from now on to be consistent with SPC
