April 2014 Newsletter
Dear iTech Subscriber,
i can do anything with iTech Solutions
Today is the long anticipated day that the entire IBM i community has been waiting for, a new release of IBM i 7.2 and new Power8 based machines. Exciting! Last month we told you that IBM had announced 7.2 would be available soon, but we couldn’t discuss it in any more detail. iTech Solutions has been a beta site for IBM i 7.2 now for 3 to 4 months, and the release has been rock solid. There are so many cool new features and functions in this release, you are certainly going to want to learn more. I will go into more details on both 7.2, as well as Power8 based machines in this newsletter. I was at IBM in Rochester last week and was able to see first hand the new Power8 based machines. Very impressive. I also want to share this chart, on two additional releases planned after 7.2 which was presented in Rochester. Now, as you can see IBM removed some of the future dates, but the important item here is at least two more releases of IBM i and the continuing of new Technology Refreshes every 6 months. I was speaking to Dave Norman (Director, IBM i Development) last week and he said they were already working on these releases that come after IBM i 7.2. Also, lets not forget that IBM i is a major contributor to Power Systems revenue. All great news for IBM i going forward.
This issue of our newsletter has 6 articles. In the first article, we will discuss Whats new with 7.2. The second article is our blog on how to upgrade to IBM i 7.2, what you need to know. The third article is on the new Power8 machines. The fourth article is migrating from ProtectTier. The fifth article lists some of the upcoming events in which iTech Solutions will be participating. The last article is for your reference with updated PTF information. Please note that for all 7.1 customers that are on the Quarterly or Semi-annual iTech Solutions PTF maintenance plan, we will be installing Technology Refresh 7 for you on your next application of PTFs, and beginning in June Technology Refresh 8.

What you will need to know to upgrade to IBM i 7.2.
If an upgrade to your current IBM i (OS/400 or i5/OS) operating system is something you’ve been putting off for quite some time, then the time has certainly come.
With IBM’s latest release of IBM i version 7.2, this release is packed with some really cool things. How long can you afford to keep waiting? First, let me say that we have been a beta site for IBM i 7.2 over the last 3 to 4 months, and this release has been rock solid.
Upgrades, updates, PTFs, enhancements are nothing new to the IBM i community. IBM has heavily invested in what was OS/400 up to what we now call IBM i during the last 26 years. While they have certainly changed the methodology of delivering new features and functions in 7.1 with Technology Refreshes, the new enhancements were what we needed.
Technology Refreshes have been coming out every 6 months over the last 4 years for 7.1, and you should have been taken advantage of these to quickly and easily get the new enhancements. Of course, if you weren’t on 7.1 you couldn’t take advantage of these as 6.1 didn’t have them, and V5R4 is ancient….
IBM has announced 5 new POWER8 based machines, that are called “Scale-out” machines. Hence, they all start with an S. The naming convention is S8su, where s is the number of sockets, and u is the height. So, an S824 would be a Scale out POWER 8 machine, with two sockets and four “U” in height. There are two other machines that have an L after them, and they just run Linux. Out of the 5 machines, just two will be used for IBM i, and they are the 4U versions. Currently you can either get a 2 socket (Like the previous Power7 740 class machine) or 1 socket machine (like the previous POWER7 720 class machine). At this point, we haven’t even started to talk how many cores on each of the sockets, we will do that shortly. One item to note, is that this is the start of a roll out, and that no other machines will be announced at this point. Currently, there is no P05 machine, so if you want a P05, you would stay with the POWER7 4-Core machine. Let’s be realistic, if you need a P05 machine, the POWER7+ 720 4 core machine is pretty powerful for an entry machine.
You can get the S814 as a Rack mount or a tower. On both the S824 & S814 machines, you will notice that there are dual power supplies, and each power supplies has two electrical cords. So, to have redundancy, you would have 4 power cords. The one socket machine can have 1 Dual Chip Module that can have 6, 8, 10, or 12 cores. That is all P10. The first machines will have upto 1TB of memory per socket. The S814 has either 3.0 Ghz or 3.7 Ghz processors. There are 7 PCIe Gen3 slots that are Hot Plugable. Yes, Hot Plugable is back, and was certainly a shortcoming on the Power7 machines. The POWER8 machines have smart acceleration enabled by Coherent Accelerator Processor Interface (CAPI) technologies. The POWER8 processors also support 8 simultaneous threads.
These machines (S814 & S824) come with 3 different backplanes, but really the only one of interest to IBM i users will be the one with 18 SSF disk bays and the high performance integrated disk controller. This internal disk controller, has 7GB of compressed write cache. That should be fantastic, in fact enough performance to drive the entire 18 bays full of SSDs.
The S824 will have everything the S814 has, except it will be a P20 class machine, and have 11 PCIe Gen3 slots. In addition, it has a built-in Easy Tier, with an additional location for SSD drives, that you can put in 8 drives.
You can attach external disks to disk controllers in the CEC, but there are currently no external card towers. This will be resolved in the future, but this is what I meant by a roll out of the POWER8 product line. Still, a set of high performance disk controllers can support so many disks, that this shouldn’t be an issue for you.

People are always asking me how often they should be performing PTF maintenance, and when is the right time to upgrade their operating system. I updated this article from last month with the current levels of PTFs. Let’s look at PTFs. First, PTFs are Program Temporary Fixes that are created by IBM to fix a problem that has occurred or to possibly prevent a problem from occurring. In addition, some times PTFs add new functionality, security, or improve performance. Therefore, I am always dumbfounded as to why customers do not perform PTF maintenance on their machine at least quarterly. If IBM has come out with a fix for your disk drives, why do you want to wait for your disk drive to fail with that problem, only to be told that there is a fix for that problem, and if you had applied the PTF beforehand, you would have averted the problem. Therefore, I think a quarterly PTF maintenance strategy is a smart move. Many of our customers are on our quarterly PTF maintenance program, and that provides them with the peace of mind of knowing their system is up to date on PTFs. Below is a table of the major group PTFs for the last few releases. This is what we are installing for our customers on iTech Solutions Quarterly Maintenance program.
The easiest way to check your levels is to issue the command WRKPTFGRP. They should all have a status of installed, and you should be up to the latest for all the above, based upon your release. Now there are more groups than the ones listed above, but these are the general ones that most people require. We can help you know which group PTFs you should be installing on your machine based upon your licensed programs. Here is a nice tidbit. The Cumulative PTF package number is broken down as YDDD, where Y is the year and DDD is the day it was released. Therefore, if we look at the cumulative package for V5R4, the ID is 9104. We can determine that it was created on the 104th day of 2009, which is April 14, 2009. Look at your machine and this will give you a quick indication of just how far out of date in PTFs you may be. I left V5R1 & V5R2 off the list, because if you are on V5R1 or V5R2, you don’t need to be worrying about PTFs, you really need to be upgrading your operating system. The same can be said for V5R3, but there are still customers who are on those releases.
If you have a Hardware Management Console (HMC,) you should be running:
|HMC||V7R7.8||SP1 eFix MH01416|
|or||V7R7.7||SP3 eFix MH01409|
If you have an Flexible Service Processor (FSP) your firmware should be:
|Power5 or 5+||520, 515, 525, 550, 570||SF240_418|
|Power6||940x, M15, M25, M50||EL350_149|
|8203-E4A, 8204-E8A, 8204-E4A||EL350_149|
|MMA, 560, 570||EM350_149|
|Power7||8231-E1B, 8202-E4B, 8231-E2B, 8205-E6B, 8233-E8B, 8236-E8C||AL730_127|
|8231-E1C, 8202-E4C, 8205-E6C||AL740_126|
|Power7+||8231-E1D, 8202-E4D, 8231-E2D, 8205-E6D||AL770_076|
