Sampling Techdocs : December 2009 - January 2010

Here we are again with some new and interesting reading material from TechDocs.
  • Presentation : IMS 11 - Easier than Ever
    White paper :
    IMS Version 11 Installation and Migration Tips
    Here's two interesting documents on IMS V11. The 75 page presentation introduces you to the new functions of IMS V11 (including speaker notes). The white paper "contains planning information for installations migrating to IMS Version 11. It includes a list of prerequisite software and APARs. It describes considerations for compatibility with previous versions of IMS and for use with DB2 and CICS. Migration tasks are explained. Tips for migrating to IMS 11 from IMS 10, IMS 9 and earlier versions of IMS are provided. The document includes extensive references to other information on IMS Version 11". Definitely worth a read.

  • White paper : OSA-Express3 Multi-ports per CHPID Definitions
    I've mentioned this before but it has now been updated as the port restrictions on CHPID type OSC have been removed since the end of last year.

  • Technical document : Manual Configuration of Linux for XIV Attachment
    I already mentioned that I also obtained my technical certification for XIV. So as my job description changes a bit, the focus of this blog will also be on XIV from time to time. Here's a first : this document describes how to "setup a Linux server manually for Fibre Channel attachment to an XIV" when you don't want or can't use the Host Attachment Packages IBM is providing with XIV.
  • Presentation: STP Role Assignment Considerations
    This presentation is intended to help customers make decisions about where to assign STP server roles. It gives some best practices, a couple of recovery scenarios and it explains what messages are generated.
  • Presentation : TS7700 Release 1.6 Technical Overview
    I already mentioned that there was no actual announcement for Release 1.6 of the TS7700 Virtualization Engine. Well, here's a nice and comprehensive presentation covering all the new functions. It also includes the audio of the presentation. The audio usually gives you a lot more information than what's on the slides and there's practically always some interesting Q&A session at the end . . . like with this one.
Well that's it for now. As I always say : just check them out !

IBM Announcement : z10 EC GA3 and z10 BC GA2

As I told you in my last post, IBM made a huge amount of announcements last Tuesday. Here's a first one on improvements for the z10 : 'IBM System z10 - Delivering security-rich offerings to protect your data (ZG09-0798)'. In the past, we sometimes saw huge amounts of new features at a new GA, but this time I think it's rather limited. Still, there are some interesting new things. I'll give you three of them. You can explore the rest of them in the announcement itself. It's a.o. about STP Enhancements and z/OS Alerts for error conditions, HMC/SE Digitally Signed Firmware . . .
  • Next generation of cryptographic feature with new Crypto-Express3 card
    I'm not that familiar with encryption and stuff, so I'm not going to divert on the new functions. But I do want to mention a statement of direction regarding Crypto-Express2 : "The IBM System z10 EC and z10 BC will be the last servers to offer Crypto Express2 (#0863) as a feature, either as part of a new-build order, or carried forward on an upgrade".
  • Capacity for Planned Events (CPE) enhancement
    As you know 'Capacity for Planned Events' was announced along with the z10 and functions as a kind of equivalent to CBU for planned events. Up to now you could turn on the full available capacity for the machine for a three-day planned period. Now you are able to limit this to the capacity you actually need and this should imply a cost reduction for your CPE activation.
  • Configuration flexibility for OSA-ICC cards
    "You can now exploit the four ports on an OSA-Express3 1000BASE-T Ethernet feature on the z10 EC and z10 BC, or the two ports on an OSA-Express3-2P 1000BASE-T on a z10 BC, when defining the feature as an Integrated Console Controller (OSA-ICC)" with CHPID type OSC. This means e.g. on a four-port card there are two PCI-E adapters with each two ports. But until now you lost one of the two ports when defining one of them with CHPID type OSC. This limitation has now been removed !
There's one other Statement of Direction I would like to mention : "On future System z servers, IBM intends to support optional overhead cabling. (...). Overhead cabling is designed to provide an additional option and increased flexibility, to help remove floor hazards in a non-raised-floor environment, and to help increase air flow in a raised-floor environment".

If you're interested in specific features, watch out for the availability dates. Most of the features, like the Crypto Express3 card, will be available on November 20, 2009. The Improved Capacity for Planned Events options become available on December 31, 2009 and the OSA multi-port support for CHPID type OSC is scheduled somewhere in the first quarter of 2010.

Sampling Techdocs : April - June 2009

It's been a while, but here we are again with some new and interesting reading material from TechDocs.
  • White Paper : IBM System Storage DS8000 with SSDs An In-Depth Look at SSD Performance in the DS8000 and An Assessment of SSD Performance in the IBM System Storage DS8000
    Two recent white papers on the use, best practices and performance of SSDs (Solid State Drives).

  • Presentation (with notes) : IMS Data Sharing
    "IMS data sharing allows multiple IMS systems to share databases with full update capability from all systems. IMS data sharing may be used to improve availability, increase capacity, and simplify applications. This presentation provides potential users with an explanation of data sharing and information on implementing it."

  • Technical Document : OSA-ICC experiences. Usage guide for z/OS and z/VM
    This is a very nice document for any one who wants to install the OSA-Express Integrated Console Controller (OSA-ICC) support of the 1000BASE-T card. It really takes you by the hand through chapters like OSA-ICC definitions on HMC, OSA-ICC VTAM Definition on z/OS, Implementing an OSA-ICC connection for z/VM and Connect to TSO using PCOMM & OSA-ICC.

  • White Paper : Software Requirements for Running SAP on System z
    Thinking about a consolidation of SAP on System z ? Here's a short 10-page introduction on what is required to run System z as the database server and Linux on System z as the application server.

  • Presentation : z/OS System Initialization Logic (IPL)
    We're closing with a verrrrry nice presentation from Riaz Ahmad : "This presentation describes general processing involved initializing z/OS System from the IPL process until the system is ready to start JES2 or JES3"
Well that's it for now. As I always say : just check them out !

z10 BC (part 2) and z10 EC GA2

In my previous post I discussed the new functionalities for the System z10 BC. As part two of the z10 BC announcement I’m going to comment on some of the features that are announced simultaneously for the z10 BC (‘IBM System z10 Business Class - The smart choice for your business. z can do IT better (ZG08-0806)’) and the z10 EC (‘IBM System z10 Business Class - The smart choice for your business. z can do IT better (ZG08-0843)’. As you’ll notice on the picture below, there’s much more than what I can discuss in one post, so I guess I’ll talk about some of the other features in the near future.

OSA-Express3
With the z10 EC we saw the first announcement of one OSA-Express3 card (10GBe). The range of OSA-Express3 cards has now been largely extended. The cards also have twice as much ports as on the OSA-Express2 cards. This means less CHPIDs, less I/O slots and perhaps less I/O cages (z10 EC) or I/O drawers (z10 BC). An overview :
  • The z10 OSA-Express3 – 10 GbE card is either Long Range (LR) with single mode fiber or Short Range (SR) with multimode fiber. There are 2 ports per card.
  • The z10 OSA-Express3 GbE comes in a Long Wave (LX) and a Short Wave (SX) version. The cards have 4 ports and for the z10 BC there’s a Short Wave (SX) card with 2 ports.
  • The z10 OSA-Express3 1000Base-T card keeps the same functionalities as its predecessor (e.g. OSA Integrated Console Controller). The card has 4 ports and again there’s a 2 port version for the z10 BC.
Z10 High Performance FICON for System z (zHPF)
If you thought that the FICON performance wizards had pulled the last trick out of their sleeves with MIDAW, then think again. They now have come up with z10 High Performance FICON (zHPF) in order to substantially reduce channel overhead once again. It is mainly with small block sizes that the performance is largely improved, in other words mainly for online transaction processing.
It’s only available on the z10 and you have to be at least on z/OS 1.8. There’s a ZHPF=YES/NO parameter in the IECIOSxx member in the SYS1.PARMLIB which has to be activated (default is NO). For the moment it will only work with the DS8000 with R4.1 as it’s the only Control Unit which support this feature for the moment. This DS8000 enhancement was also announced yesterday : IBM System Storage DS8000 series (Machine type 239x) function authorization for zHPF and RMZ resync (ZG08-0908).

Capacity on Demand
‘Capacity on Demand’ has had many enhancements over the last couple of years. The z10 BC offers the same possibilities as the z10 EC : Capacity Backup (CBU), Capacity for Planned Events (CPE) and On/Off Capacity on Demand (OOCoD). Still some new functionalities are introduced for both systems.

There’s a whole Redbook describing every variation, but put simply you can order one or more records for each of these offerings. That way, you can have up to 200 records at your disposal on the Support Element. At that moment the records are said to be ‘staged’. In order to be able to actually use them, you have to install them. You can have a maximum of 8 installed records or tokens. This can e.g. be a combination of CBU tokens for CPs, CBU tokens for zIIPs and one token for On/Off CoD. This way of working was already introduced with the z10 EC, but the number of tokens is extended from 4 to 8.

The major change has to do with the way you are charged for your ‘capacity on demand’. There is no change for CBU and CPE : there’s a hardware charge but no additional software charge. For On/Off CoD you still have hardware as well assoftware charges. So what’s the big difference now ? Well, until now when OOCoD was activated, the charges were calculated according to the number of days it was used. In the new system, this is called ‘Post Paid OOCoD’. Completely new is that you can now also order ‘Pre Paid records’. You buy OOCoD records for a certain capacity in advance e.g. at the same time you order your new z10 BC. When you activate these records afterwards, there’s no payment to be done any more. It’s quite obvious (as opposed to the post-paid records) that these records have no expiration date.

There’s one other new feature I only come across in the z10 BC announcement : you are entitled to one (1) On/Off CoD Test per server with a maximum duration of 24 hours.

Other
From now on you can order Plan Ahead Memory. It means that you order more memory than you’ll be needing at this very moment. You pay immediately for the memory that you are actually using and you partially pay for the ‘plan ahead memory’, which you’re not yet using. When this memory is activated, in one or more steps, afterwards, you pay the rest of the charges for it. This can help you plan for nondisruptive memory upgrades.

The use of PSIFB (Parallel Sysplex using InFiniBand) has also been extended. From now on InfiniBand can also be used as a replacement for ISC-3 links. For the moment it’s exclusively available on the z10 with an unrepeated distance of 10km. Unlike the ISC-3 links, it does not use an I/O slot in the I/O drawer.

The HiperDispatch feature should have little or no impact with the z10 BC.

And there’s one other little sentence I’d like to mention that might perhaps slip your attention when browsing through the announcement. Just like on the z10 BC there's a “62% price reduction on memory for z10 EC when purchased after October 21, 2008, and with a specialty engine for new workloads (…) limited to 16GB per specialty engine".
