SPARTA President’s Corner

contributed by Randy Springs



As we enter the holiday season, with all of its demands on our time, I hope to be able to stop and reflect on all that I have to be thankful for. We work in an area that has great possibilities in making life better for a majority of people. I have been amazed this year to see the benefits of IT in the medical field. Naturally, there are some who will try to take advantage of technology to gain a personal advantage, but with proper networking and communication with others in our industry, we can move forward in positive ways to help each other live our lives with less stress and more free time for friends and family. I am thankful for each of you and your participation in SPARTA and other networking groups as we share our unique challenges and hopefully find some answers.

Please plan to join your colleagues for subs, networking, and education on Tuesday, December 5 at 6:15 p.m. at our usual LabCorp location.

Where to use Linux on IBM Z
- Most customers first consider Linux on IBM Z for server consolidation
- From there customers start using Linux on IBM Z to front-end their legacy z/OS, z/VSE, and z/TPF systems
- Finally,Linux on IBM Z becomes a platform for new workloads
- Of course, the order may be different for you
- My customer experience shows that usage today is split more-or-less evenly between these three environments


Fit for purpose, workload and situation (IBM Z vs x86 vs UNIX)
- Many factors influence platform selection, making it difficult to present a simple selection matrix
- Some factors are specific to each business, others are common to all and can be generalized
- - Time Horizon
- - ISV Support
- - Nonfunctional Requirements (Availability, Scalability, Security, DR, etc.)
- - Power, cooling, floor space constraints
- - Strategic Direction and Standards
- - TCO Model
- - Skills
- - Politics
- - Platform Architecture
- - Technology Adoption Level
- - Deployment Model
- - Problem Size


What makes the best fit?

Selecting the "right" applications
- Not all middleware (Open Source or commercial) is available for Linux on IBM Z
- - Major IBM and ISV server middleware is available
- - Most Open Source server packages are available
- - You need to research availability of all the software you will be using before you proceed further
- - - If particular piece of software is not available, contact IBM or your BP to ask for help (the may or may not be able to provide a solution)
- - - Don't assume when a vendor tells you that Linux on IBM Z is supported, they often don't know what they are talking about (speak to a techie, not a rep)
- - - If all the pieces an application requires are not available, find a different application


Selecting a hypervisor
- Hardware Partitioning Solutions
- - IBM Processor Resource/System Manager (PR/SM)
- - IBM Dynamic Partition Manager (DPM)
- Virtualization Solutions
- - IBM z/VMÆ + IBM Wave

Should you consolidate servers?
- Once you know that your applications will run on Linux on IBM Z and you have decided on how to run them, the next step is to determine:
- - How large a IBM Z server is required?
- - Is it cost effective to consolidate the servers?
- - Performance on IBM Z CPUs is comparable to CPUs on other platforms of similar speed
- - - CPU speed is not the entire story - it ís in the architecture!
- - - Architecture designed for multiple or consolidated workloads
- - - IBM Z has definite advantage with applications that have mixed CPU and I/O
- - Good planning is essential
- - IBM can perform sizing estimates and assist with planning and initial installation needs


Tools to assist in consolidation analysis
- IBM has several no-charge offerings available for this effort
- - SURF, SCON, RACEv, and IT Economics (Eagle) studies are provided by IBMers
- - LinuxONE Cost Savings Estimator analysis is provided by IBMers or business partners
- - The IBM LinuxONE TCO calculator is available on the web to anyone


SURF and SCON
- SURF is a tool which takes basic performance data from distributed servers along with server definitions from SCON to derive a concurrent peak utilization
- SCON is a tool which uses the utilization information from SURF (or manually derived) along with server definitions from IDEAS International to provide an IBM Z server sizing (IFLs or MIPS)
- These tools are Lotus 1-2-3 spreadsheets (really) and the analysis is done by IBMers (usually in the WSC)
- Even if you don't use the tools, the collection exercise is a very useful exercise


SCON worksheet - Workload Examples
No. - Workload Type - Typifying Middleware - Workload Category Description
1. Middleware-Based Default - N/A - Null
2. CPU Intensive: High CPU utilization, lots of calculations, small memory usage, very high cache hits rates.
3. Java Heavy - WAS, Portal Server, Weblogic - SCON: WAS: Substantial Java Application. Java applications that are compute intensive (e.g. large XML object processing)
4. Java Medium - WESB, Process Server - Middle of the road java applications. Use this value if you do not know details about a Java application
5. Java Lite - WAS, BEA Weblogic - SCON: WAS: Little Java Content. Java applications that are heavy I/O users
6. Database - DB2, Oracle - SCON: DB Production. Database and "database-like" work in service to batch or transactional read/write applications.
7. Mixed High - Multiple applications on distributed systems, or applications with multiple contexts
8. Mixed Low - VMware, Webfocus - Multiple applications on distributed systems, or applications with multiple contexts with higher degree of virtualization or context switching than Mixed High
9. Data Intense, I/O Bound - Extremely large memory working set sizes, very active context switching, low cache hit rates (lots of virtualization).
10. TSM - Tivoli Storage Manager - SCON: Misc: Tivoli Storage Manager


Note: There are 35 workloads, this is a partial list


SCON Worksheet - Accuracy is essential
- Fill out the SCON worksheet completely, the more accurate the data the more accurate the result
- The information required is:
- - Machine Name (this is used in SURF as the file name of the data file)
- - Vendor (IBM, CISCO, Dell, Fujitsu/Siemens, HP, Oracle/Sun)
- - Model/Type , # Chips, # Cores, CPU Ghz (this is used in SCON along with the vendor to find the right entry in the IDEAS International database)
- - Mode (native or virtual)
- - Entitled Cap (if running virtualized, the cap in number of cores, i.e. on a 4 core system if a virtual image gets 1.5 cores use "1.5")
- - Average Utilization, Peak Utilization (SURF will derive accurate info)
- - Quantity of Identical Machines
- - Type of Workload (numeric code)
- - Comments (anything that may be useful to the person doing the analysis)


For a copy of the SCON Sizing Input Sheet, e-mail me


SURF Data Collection
- Please select at least a day's worth of data but not more than 15 days
- These days should be representative of the workload that you would like to have analyzed
- Please ensure that the data sent includes peak workload intervals, the intervals should be 15 minute intervals and that the time stamps for all servers match up (required to give an accurate concurrent peak)
- There should be one file for each server, name the file with the server name and a suffix of csv (e.g. altanta2.csv)
- The data in the file should contain one line per time interval (tab delimited)
- The following are required fields:
- - Date MM/DD/YY - Required
- - Time HH:MM:SS - Required
- - USR Number - Required
- - SYS Number - Required
- The following are optional fields, but it is suggested that they be included:
- - WAIT Number - Optional
- - IDLE Number - Optional
- Example of a log file:
- - Date Time Usr Sys Wait I/O Idle
- - 11/8/2007 13:05:00 7 4 0 89
- - 11/8/2007 13:10:00 10 5 0 85
- - 11/8/2007 13:15:00 11 4 0 86
- - 11/8/2007 13:20:01 13 5 0 82
- The order of the fields is not critical, but do NOT combine the day and time into one field.
- These fields are the standard output of a UNIX or LINUX or WINDOWS performance monitor like VMSTAT, SYSTAT, or Perfmon


For a copy of the SURF Data Collection Guide, e-mail me


SURF - Output is detailed utilization info and graphs
- SURF produces several tables and graphics using the performance data files and the SCON spreadsheet ís server information
- SURF will determine when and what the concurrent peak was (in this case 2,441 MIPS equivalent)
- SURF will use this information to populate the SCON spreadsheet


SCON - Output is estimated IFLs
- SCON used the IDEAS International RPE data along with the workload information supplied by the customer to determine equivalent IBM Z MIPS
- Using either customer provided capacity information or utilization information from SURF, SCON translates this into required IFLs for the selected processor family


RACEv - TCO analysis
- Right-fitting Applications into Consolidated Environments (RACEv) is an approach that is used by IBMers (usually IBM Z Client Architects) to size and subsequently project the financial benefits of consolidating to a virtualized server environment
- It demonstrates which platform option offers the most attractive financial attributes for your next project
- RACEv requires a lot of input data from the customer as it provides a true Total Cost of Ownership study covering 5 years and all costs related to a project
- Using SURF/SCON first will provide accurate data for the RACEv analysis (not required, but I recommend it)
- Consolidation targets can be Linux on IBM Z, AIX, or Linux on Power, and other platforms so you get a true 5-year comparative analysis


IBM LinuxONE TCO calculator
- If you want a quick view of what the TCO would be, try the TCO calculator and see:
- - Your estimated TCO over three, four or five years
- - Your likely payback in months, ROI and IRR
- - Your likely consolidation savings
- How it works
- - By answering just a few questions such as hardware, workload type and software, the LinuxONE TCO calculator provides a high-level total cost of ownership based on your answers and industry-proven assumptions.
- - While this is not intended to provide an exact cost, in just a few minutes you can see how LinuxONE can help you. If you like what you see, contact us for a complimentary on-site assessment.
- Helps to calculate the financial advantage of LinuxONE with:
- - 3 to 5 year TCO comparison between your x86 environment and a LinuxONE solution
- - Payback in number of months, ROI and IRR
- - Cost reduction as a result of consolidation onto LinuxONE
- - Calculates TCO factors such as hardware, workload type, IBM and ISV software, facility costs (space, energy), maintenance charges, server utilization, hypervisors, migration
- The SCON worksheet can be used to collect the required data
- The calculator is available at
https://extbasicdsgtool.podc.sl.edst.ibm.com/dsg/linuxone/

http://www.ibm.com/iteconomics


Sizing for new workloads
- New workloads can be front-ending a legacy system (z/OS, z/VSE, z/TPF)
- - Examples include Cognos, InfoSphere, WebSphere, SAP
- New workloads can also be applications that might otherwise be run on an x86 or RISC server
- - Examples include Oracle DB, Db2 LUW, WebSphere, or Open Source projects
- The same tools are used as for server consolidation, but customers have to estimate the "distributed" server capacity
- - Most major software products have tools which provide an estimate of the x86 severs required for a given workload and this info can be used as input to the Linux on IBM Z sizing tools


Summary
- There are several tools available which can help you to size a Linux on IBM Z workload
- Accuracy of the data you use as input to the tools is essential to getting a valid sizing
- First make sure your workload will run on Linux on IBM Z
- Second ensure the required capacity makes financial sense
- Good luck - IBM and your business partner are here to help you in building a successful solution

Virtualizing the Mainframe, 50 Years and Going Strong

Contributed By Ed Webb


"Did you know this year marks 50 years of mainframe virtualization? In fact, the majority of the concepts of virtualization on all platforms began on mainframes. What many mainframers today don’t realize is that they benefit from this long history, even if they are not running virtualization management software such as z/VM. What everyone commonly understands as logical partition management on the machines (LPAR or PR/SM) has its roots in the same VM from the mid-1980s. IBM depends on a customized version of VM to develop and test new releases on all of the mainframe operating systems, including z/OS and z/VSE. Many vendors also depend on VM to test their products. Many VM functions have been provided using Service Virtual Machines, making VM the origin of Client / Server technology."

Humor


Mainframe Branding Insanity

contributed by Ed Webb


"Prompted by IBM’s rename of “System z” to “z Systems,” last year’s “zWhat (or z/What??)” by Phil Smith III discussed IBM branding. Remarkably, that story is already out of date: With its July 2017 z14 announcement, IBM renamed the mainframe line yet again, this time to “IBM Z”—and yes, that’s a capital “Z,” for the first time.

It’s hard not to conclude that something odd is going on at IBM."
