SCI’s latest Microsoft ESRP performance report as of April 2017

In Dell, Dell PowerVault MD3820f, DS 1016R, EonStor, ESRP, ESRP v4/Exchange 2013, Infortrend by Administrator0 Comments

This Storage Intelligence (StorInt™) dispatch covers Microsoft Exchange 2010 and Exchange 2013/2016 Solution Review Program (ESRP) results[1].  Since we last reviewed this from 1001 to 5000 mailbox category nine months ago, there have been 4 new submissions that include the InforTrend DS 1016R and 3 Dell PowerVault MD3820F (for FC-Direct, FC-SAN and SAS connected storage). Two of our top 10 charts have changed which we show below.

Latest ESRP V3.0 & 4.0 (E2010&E2013) performance

In Figure 1 we show our Silverton Consulting, Exchange database transfers per second chart per spindle (disk drive).

Figure 1 SCI’s ESRP reported top ten database transfers/second/spindle

In Figure 1 one can see the InforTrend EonStor DS 1016R came in at number five with ~93 database transfers per second per spindle.  The FC attached DS 1016R used 16-4TB 7200RPM disk drives and with ~1480 database transfers/sec they were able to place in the top 10 here. which placed. In Figure 1, there are a three of submissions using 15Krpm (3) and one using 10Krpm, with the rest being 7.2Krpm drives. Fujitsu’s DX600 S3 was the only higher ranked submission using 7.2Krpm drives. Infortrend was the only submission in Figure 3 using 4TB drives.

Next, we report on ESRP reported Log Playback Time in Figure 2.

Figure 2 ESRP Top 10 log playback time results

In Figure 2, we can see all three new Dell PowerVault MD3820f submissions ranking at number three, four and five, with 0.41, 0.43 and 0.51 second log playback times. All three systems were configured the same with 15 900GB 10Krpm drives. We like log playback because it’s a mixture of background Exchange database updates at the same time as sequentially playing back log’s against the active database.

What’s surprising to us is that these relatively new Dell PowerVault systems didn’t do as well in database transfers per second per drive spindle (see Figure 1). All three of these systems didn’t hit very good database transfer rates. But the did surprisingly well here, in log playback. If we had to guess we would say that database transfers per second is a heavily cache influenced workload and the log playback is more just raw disk speed. As evidence of this hypothesis there are only 2 7.2Krpm drive submissions in the above list (NetApp Fas2040 and HPE Smart Array P411/D2600) and all the rest are 10K or 15Krpm drive submissions.

Summary

We’re always happy to see new submissions, especially in the midrange 1K to 5K mailbox category where we feel a majority of organizations probably fall. We firmly believe that ESRP is the most comprehensive, real world measure of storage system performance that exists today, even if Microsoft won’t call it a “benchmark”.  Submissions at this mid-range mailbox count category aren’t as sexy as the over 5K mailboxes but still provide useful information for mid-sized customers.

It’s also good to see different interface submissions. The Dell PowerVault MD3820f showed how the same storage performs under FC direct, FC SAN and SAS host interfaces. It’s not surprising that the SAS system performed best in Log Playback but it also did best in (not shown) database transfers per second.
