That was pretty fast...so I did another installation test and timed it at 76 seconds.
I traded tweets with Keith Brooks who interestingly did a upgrade time trial on Windows a few years ago. Three minutes is pretty darn good for an upgrade, especially for a couple of years ago.
I decided to record a test installation and a test upgrade tonight on my Power Systems hardware and IBM i operating environment. To be fair, I knew I could do better than my own 76 second test because it was in the middle of the business day with a few hundred users on the system hitting our ERP to Domino to Sametime and everything in between.
So tonight I installed an 8.5.1 server with Fix Pack 5. First, how is that possible? On this particular IBM i partition I have versions 8.5.0, 8.5.1, 8.5.2, 8.5.3 and 9 installed with a fix pack assigned to most of them. The 8.5.1 licensed program has been "augmented" with FP5 which means any new or upgraded-to 8.5.1 server is by default at 8.5.1 FP5. Any new or upgraded-to 8.5.2 server is at 8.5.2 FP2, etc. This is just how Domino on IBM i works. A Fix Pack patches all existing or future Domino servers for it's corresponding release.
This installation took 57 seconds. Not half bad.
The upgrade from 8.5.1 FP5 to 8.5.3 took 1 minute and 50 seconds:
20 seconds to shut the server down.
70 seconds to update it to 8.5.3.
20 seconds to start the server back up, upgrade the NAB and load all tasks. Note that a server reboot (IPL) is never required for this type of activity.
I would really like to see someone do this with some serious iron. Not that mine is anything to laugh at, but I'd want to see how fast you can do this on a higher end Power Systems server like a 770 or 795. I'm running IBM i 7.1 TR5 on a lower end 6-way IBM Power Systems 8202-E4B (Power 720 Express) with 96 GB RAM. The auxilliary storage pool Domino runs in has 2.5 TB disk on 20 drives. How fast can a Domino install or upgrade really get? If you can shave more seconds off then I'd love to hear about it.
