And, out of curiosity, what was the result of the CPU test? I suspect this was to determine how many CPU's you would need to license for the software.

We ran a very extensive set of Oracle-Java benchmarks that compared I/O's on an EMC Symm under AIX/P-570 versus the same EMC Symm but with 3390-m3 under zVM/SLES 9.3. We were running a very I/O intensive application that was hitting close to 5000 I/O's per second for hours at a time. This is the way it behaves in production so it was a real-life workload. We found that the I/O response was very similar between both environments once we tuned and spread the I/O's across as many devices as possible so a single device would never go over 30% busy when doing lots of I/O's. We were able to achieve an overall response of 5 msec under both platforms. This was done because we needed to test the CPU's and not the I/O subsystem as part of our decision. Yes, it does take longer to setup and configure disk under zVM/Linux than it did under the P-570/AIX platform. However, we only care about response time for our applications so we can put up with the slow formatting of disk space. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
