One astute reader of our performance reports pointed out that some ESRP results could be skewed by the number of drives that are used during a run. So, we included a database transfers per spindle chart in our latest Exchange Solution Review Program (ESRP) report on 1001 to 5000 mailboxes in our latest newsletter. The chart [...]

This chart shows the top 10 CIFS throughput benchmark results as of the end of last year. As observed in the chart Apple’s Xserve running Snow Leopard took top performance with over 40K CIFS throughput operations per second. My [...]

One problem with this chart is that it really only shows 4 subsystems: HDS and their OEM partner HP; IBM DS5300 [...]
Read the rest of this entry »In our quarterly study on Exchange Solution Reviewed Program (ESRP) results we show a number of charts to get a good picture of storage subsystem performance under Exchange workloads. The two that are of interest to most data centers are both the normalized and un-normalized database transfer (DB xfer) charts. The problem with [...]
Read the rest of this entry »The adjacent chart is from our September newsletter and shows the top 10 NFSv3 throughput results from the latest SPEC(R) sfs2008 benchmark runs published as of 25 September 2009.
There have been a number of recent announcements of newer SPECsfs2008 results in the news of late, namely Symantec’s FileStore and Avere Systems releases but these results [...]
The above chart shows the top 12 LRT(tm) (least response time) results for Storage Performance Council’s SPC-1 benchmark. The vertical axis is the LRT in milliseconds (msec.) for the top benchmark runs. As can be seen the two subsystems from TMS (RamSan400 and RamSan320) dominate this category with LRTs significantly less than 2.5msec. [...]
Read the rest of this entry »As described more fully in last months SCI’s newsletter, to the left is a chart depicting Exchange Solution Reporting Program (ESRP) results for up to 1000 mailboxes in the database read and write per second category. This top 10 chart is dominated by HP’s new MSA 2000fc G2 product.
Microsoft will tell you that ESRP is [...]
