My Sun Storage 7410 perf limits

As part of my role in Fishworks, I push systems to their limits to investigate and solve bottlenecks. Limits can be useful to consider as a possible upper bound of performance - as it shows what the target can do. I thought these results would make for some interesting blog posts if I could explain the setup, describe what the tests were, and include screenshots of these results in action. (update: I've included results from colleagues who have tested in the same manner.)

To summarize the performance limits that I found for a single Sun Storage 7410 head node:

All tests are performed on Ethernet (usually 10 GbE) unless otherwise specified ("IB" == InfiniBand).

Like many products, the 7410 will undergo software and hardware updates over time. This page currently has results for:

  • 7410 Barcelona: The initial release, with four quad-core AMD Opteron CPUs (Barcelona), and the 2008.Q4 software.
  • 7410 Istanbul: The latest release, with four six-core AMD Opteron CPUs (Istanbul), and the 2009.Q3 software.

I should make clear that these are provided as possible upper bounds - these aren't what to expect for any given workload, unless your workload was similar to what I used for these tests. Click on the results to see details of the workloads used.

These are also the limits that were found with a given farm of clients and JBODs - it's possible the 7410 could go faster with more clients and more JBODs.

Updated 3-Mar-2009: added CIFS results.

Updated 22-Sep-2009: added column for 7410 Istanbul. Results will be added as they are collected.

Updated 12-Nov-2009: added Cindi's InfiniBand results.
