The 4-node test, with 64 cores total, gave us average 129.22 MB per second per physical core for WRITEs and 121.06 MB per second per physical core for READs.
Please note that SAS recommends a minimum of 100 MB per second per physical core for WRITEs and READs.
As you can see, the above InfoScale infrastructure can produce the minimum IO throughput needs of a 40-core and for 64-core SAS Grid application. Additional testing with more cores showed the minimum of 100 MB per second per physical core for WRITEs and READs is met.
Please reach out to Veritas for more details on InfoScale and how to configure it for optimal performance in MS Azure.
