This Storage Intelligence (StorInt™) dispatch covers Microsoft Exchange 2010 (E2010) and Exchange 2013 (E2013) Solution Review Program (ESRP) results. Since we last reviewed this over 5000 mailbox category nine months ago, there have been seven new entries, the Cisco C3170 Server, HP Converged System 700, Dell PowerEdge R730xd (@8K and 10K mailboxes), NetApp E2700 and NetApp E5600. Only a few of our ESRP top ten performance charts have new entries, which we present below.
Latest ESRP V3.0 & 4.0 (E2010&E2013) performance
In Figure 1 we show an SCI derived metric, that is the aggregate database transfers per second per drive.
As can be seen in Figure 1, the new Dell PowerEdge R730xd 8K mailbox solution (#7) did well on our transfers per second per disk spindle. For this metric, we exclude all ESRP submissions that use SSDs or other flash, such that this metric provides a pure disk based performance view. Many of our other top ten charts use normalized DB transfers per second per 1K mailboxes but for this measure, the data base transfers are already normalized by disk counts in the solution.
The surprising fact about the Dell solution was that they were using 20-6TB 7200 RPM disk drives in their configuration, a relatively small number of very large disks for this over 5000 mailbox category. Of course, one explanation is that the storage was just internal 3.5” disk drives, SAS connected directly to the server. There are only a few other ESRP submissions in this over 5K mailbox category with similar configurations, most are fabric attached standalone storage with standalone servers. Dell’s results here compare well against these other solutions, and says something about their system implementation effectiveness.
In Figure 2 we show an ESRP reported metric, the top ten database backup MB per second per database throughput.
We normally prefer another database backup throughput metric, which we compute based on total database backup to the storage, but alas, there were no new entries in that top ten chart. In Figure 2, we can see the new NetApp E2700 and the new Dell R730xd 10K mailbox solution came it at #4 & #5, respectively.
Not sure how one achieves good performance on this measure. Is it small databases LUNs? Not necessarily the E2700 had 2.3TB database LUNs, while the R730xd had 5.6TB sized LUNs, and the Dell system had the largest DB LUN size in this top ten. Mailboxes per DB don’t seem to matter either, with the NetApp storage having 1111 while the Dell system had 500.
Perhaps it’s the size of the databases themselves. ESRP doesn’t report size of database directly but if I multiply the mailboxes per database times the size of each mailbox I can come up with a number that should correlate well with database size. Given that calculation, the NetApp E2700 had the largest database size and the Dell R730xd tied for 3rd largest database size.
Although there have been a number of new submissions in this over 5K category, there haven’t been any with very large mailbox counts, which typically dominate our other top ten charts. Hopefully this will change over time as we plan to revisit this category nine months from now.
