This Storage Intelligence (StorInt™) dispatch covers Microsoft Exchange 2010 (E2010) and Exchange 2013 (E2013) Solution Review Program (ESRP) results. Since we last reviewed this 1000 mailbox and under category nine months ago, there has only been one new entry, the HP MSA 1040. The HP MSA 1040 storage performed well enough to rank in the top ten for a number of our ESRP performance metrics and we present a few of them below.
Latest ESRP V3.0 & 4.0 (E2010&E2013) performance
In Figure 1 we show an SCI derived, top ten normalized database transfers per second.
As can be seen in Figure 1, the new HP MSA 1040 came in at 5th place with a total of 625 database transfers per second per 1000 mailboxes, behind the 2 HP MSA 2040s, HP P2000 G3 and an Infortrend EonStor DS 3016R which hit 1025 total database transfers per second per 1000 mailboxes. The HP MSA 1040 used dual-port, 10GbE iSCSI host interfaces to each controller and had a total of 12 4TB 7200RPM SAS2 connected disk drives for physical storage.
We prefer the normalized database transfers per second (using 1000 mailboxes) metric over the ESRP reported (absolute) database transfers per second because it’s less susceptible to variability based on mailbox counts. This is much more of a problem for the over 1000 mailbox categories. But as can be seen in Figure 1, the top four solutions supported only 800 mailboxes. For example, in absolute database transfers the Infortrend system mentioned above only achieved 828 (absolute) database transfers per second but performed significantly better on a normalized basis.
In Figure 2 we show a SCI derived metric, top ten ESRP total database backup throughput.
Once again the new HP MSA 1040 came in 5th place with 620 MB/sec of total database backup throughput. ESRP reports two database backup metrics: throughput in MB per second per database and throughput in MB per second per server. However, both are more of a server side performance metric and neither show a storage system view, which is why we prefer total database backup throughput in Figure 2.
In Figure 3 we show another SCI derived metric total database transfers per second per disk drive.
Again, the HP MSA 1040 showed up in 5th place with 52 database transfers per disk drive. The top solution here the Infortrend EonStor DS 3016R had 96 database transfers per disk drive. Normalization by mailbox counts doesn’t make as much sense here since database transfers per second per spindle is already normalizing transfers by disk drive counts.
The chart in Figure 3 mixes all speeds of disk, i.e., 15K RPM with 7.2K RPM disk drives. But the 15K RPM drive submissions in our top ten showed up in the last four slots, ranking seventh to tenth. Apparently, there’s more to ESRP database transfers than pure disk speeds.
There hasn’t been as much new activity in this 1000 mailbox and under category as we would like to see. Unclear whether this is due to the high use of DAS for Exchange storage in SMB customers or some other reason. But, there are still a large number of vendors offering SMB storage systems and ESRP remains one of the best ways to assess there overall IO performance.

Constructive comments on how to improve our analyses for any of our performance reports are always welcome. Moreover, if you detect errors in this or any of our other performance reports, please do let us know and we will correct it as soon as possible.
If you received this report from someone else, please consider signing up for your own free copy of SCI’s StorInt™ monthly newsletter using the signup block above right. We provide commentary on recent major storage system announcements as well as analyze current storage system performance results/benchmarks like this each month. We plan to analyze Microsoft ESRP results again in three months.
[Also we offer more block storage performance information plus our OLTP, Email and Throughput ChampionsCharts™ in our recently updated (May 2019) SAN Storage Buying Guide, or for more information on some select ESRP performance results please see our recently updated (May 2019) SAN-NAS Storage Buying Guide, both of which are available for purchase on our website.]
