SCI’s latest SPC performance report as of Nov. 2018

In Huawei, Lenovo, OceanStor, Uncategorized by AdministratorLeave a Comment

This Storage Intelligence (StorInt™) dispatch covers Storage Performance Council (SPC) results[1]. Over the last quarter there have been four new SPC-1 v3 submissions, Huawei Dorado OceanStor 180000 v3, Huawei OceanStor 5300 v5, Lenovo ThinkSystem DE6000H and Inspur AS5500G2, and one new SPC-2 solution, the Vexata VX100-F (Scalable NVMe Flash Array.  Most of our SPC-1 top ten charts have had changes

SPC-1 results

We begin our discussion with top ten SPC-1 IOPS™ performance in Figure 1.

Figure 1 Top 10 SPC-1 IOPS 

We had to increase the scale of Figure 1, as our new #1, the new Huawei Dorado OceanStor 180000 v3, came in at over 7 million IOPs. The Huawei 180000 v3 solution sported over 460 900GB, SAS connected, SSDs and 16 controllers. their cluster also used 8TB of DRAM. Unfortunately, none of the other new SPC-1 submissions managed to crack into the top ten in IOPS.

In Figure 2 we present SCI’s economical performance metric, top ten IOPS/$/GB 

Figure 2 SPC-1 Top 10 SPC-1 IOPS/$/GB

With a price of $2.65M, an ASU capacity of 211.3TB and attaining over 7M IOPS, the Huawei Dorado 180000 v3 came in at our new #1 with ~560K IOPS/$/GB. Also, a new entry to this top ten was the Lenovo ThinkSystem DE6000H, that came it at #10 with a price of $42.2K, an ASU capacity of 9.4TB and attaining ~460K IOPS for a ~103K IOPS/$/GB. 

As discussed in prior reports, we prefer IOPS/$/GB as a measure of the economics of IO performance rather than the SPC’s $/IOPS (now $/KIOPS). We feel our metric is not biased as much to AFA as the $/IOPS but this matters less over time, as the only non-AFA system in our top ten in Figure 2 is the (#9) Huawei OceanStor™ 6800 v3. 

The other interesting note on Figure 2 is that Huawei seems to dominate this metric, holding 6 of the top ten slots and all the top 4. This must say something about their common architecture.

SPC-2 Results

In Figure 3, we show our SPC-2 MBPS™ spider chart, which depicts each of the individual components of MBPS, Large File Processing (LFP), Large Database Query (LDQ) and Video on Demand (VoD) throughput.

In Figure 3, the Vexata VX100-F came in at our new #4 with an aggregate SPC-2 MBPS of ~49.0 GB/sec. The Vexata VX100-F solution is a dual controller system, using 64 1TB NVMe SSDs in a 3+1 RAID 5 configuration and had a combined 256GB of DRAM in the controllers with another 512GB of DRAM in 16 enterprise storage modules (ESMs, NVMe attached drive shelves). 

We can’t tell from the SPC-2 FDR report whether they used standard FC or NVMeoF/FC. But our best guess is they used standard FC given their minimum response times. One wonders how well it could have performed when using NVMeoF/FC

To our knowledge this is the first SPC-2 submission to use NVMe SSDS, but at this performance is unlikely to be the last. Of the top ten in Figure 3, four remain disk only systems (#5 HP XP7, #6 Huawei OceanStor 6800v3, #8 Oracle ZFS Storage ZS4-4 appliance and #10 Oracle ZFS Storage ZS5-2).

The Vexata VX-100F was able to generate ~766 MBPS/ SSD. Their MBPS/SSD performance was beat only by the NetApp EF560 and EF570 solutions, which came in at 1,135 and 867 MBPS/SSD, respectively. 

In Figure 4, we show the SPC-2 $/MBPS Price-Performance™ top ten.

The new Vexata VX100-F came in as our new #2, with a $5.42 $/MBPS. At a $262.6K system price and achieving 49.0 GB/sec, it placed well in SPC-2 Price-Performance. 


It’s great to see new SPC-1 and SPC-2 submissions especially when they break into the top ten charts. A new SPC-1 #1 in IOPS, that beat #2 by over 1 million more IOPSspeaks volumes about the state of performance competition in block storage today.

It’s too bad that some of the other new SPC-1 submissions didn’t achieve top ten status in our rankings but they were midrange systems and didn’t perform as well. 

As for SPC-2, Vexata started in 2014 and came out of stealth in September of 2017. That a startup is already placing top ten in SPC-2 MBPS against major storage vendors is a significant achievement and no doubt testament to the experience of Vexata’s founders and development team.  

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