Torbjörn Appehl BIO

Torbjörn Appehl started his IT-career in 1997 as a customer engineer and later country specialist for AS/400 hardware employed by IBM Sweden. Later he became program manager for the BCRS (Business Continuity and Recovery/Resiliency Services) center, building High Availability and Disaster Recovery solutions for IBM i customers in Sweden.

After leaving IBM in 2008 he worked for a number of business partners including Atea, Evry (Now TietoEVRY), and CGI. He also worked with Arcad Software to bolster their business in the Nordics.

In 2020 Torbjörn founded the IT advisory company Built on Power.

He was a board member for 10+ years and the President for 7 years of the Swedish User Group Common Sweden (Formerly known as Data3). In addition he was also a member of the Common Europe Executive Committee for 3 years.

As the leader of Common Sweden he was a key player to move the sleepy organization into a very vital part of the IBM Power user group community. Among many things he produced a members magazine that was well known all over the world.

Besides this he started IBMiCompetence.com, a networking website where IBM i experts and community members can promote their services.

In 2016 Torbjörn was recognized as an IBM Champion for IBM Power Systems after being nominated by IBM staff in Rochester and Austin.

He has been organizing a number of large conferences such as Common Sweden Fall conference (It grew from 80 to over 200 participants after a members brainstorming meeting initiated by Torbjörn), he arranged Common Europe Congress (CEC) in Sweden 2016 with over 300 participants and later helped arrange CEC in Brussels, Warsaw and Berlin.

He is producing a number of newsletters around IBM technologies. A daily newsletter you can read about HERE

He produces a newsletter for IBM ISV’s in Europe that you can find an example about HERE

From time to time he is also helping IBM, IBM Distributors and IBM Business partners with spreading information and knowledge about IBM Power Systems.

As a speaker at conferences around the world he presents topics such as:

  • IBM i Explained (IBM i for beginners)
  • Why replacing an ERP and leaving the platform often is a very bad idea
  • How to keep yourself updated
  • IBM i from 1962 until today
  • 400 Arguments for IBM i and IBM Power Systems

SAP on IBM Power – RedHat Edition

On this page we are collecting information and links regarding SAP and Redhat on IBM Power!

TCO Linux on Power
https://www.ibm.com/blogs/systems/lowering-tco-with-linux-on-ibm-power-systems/

IDC White Paper
Who Can Benefit from SAP HANA Database ans S/4HANA on IBM Power Systems?

https://www.ibm.com/downloads/cas/W4VKZJMO

“Since late 2015, SAP HANA has also been available on IBM Power Systems with IBM’s innovative IBM Power Systems architecture and processors, and IBM says that to date it has more than 3,000customers running SAP HANA on IBM Power Systems. IDC believes that IBM Power Systems is a strong differentiator for SAP HANA and S/4HANA. IBM Power Systems is designed for very data-intensive workloads such as SAP HANA, with powerful built-in virtualization that is SAP certified aswell as numerous reliability features”

Metalloinvest

https://www.ibm.com/case-studies/metalloinvest/
By adopting the SAP S/4HANA platform, Metalloinvest was able to shut down 100 IT systems and slash operating costs. More than 7,000 employees are using the new platform, which has improved efficiency and manageability. More than 2,400 employees use the SAP S/4HANA platform daily to plan and execute more than 34,000 maintenance orders each month.

Targeted audience (From IDC Whitepaper)

Businesses with SAP HANA Appliances Due for a Refresh

“Many businesses started their SAP HANA journey as many as six years ago with SAP HANA appliances on commodity architecture. This was the only solution available at the time. Those businesses are now facing a costly scale-out expansion or possibly a complete technology refresh”

Businesses on Commodity Architecture Moving to SAP HANA

“Businesses that are running their datacenter on commodity architecture that have not yet moved to SAP HANA have a choice between appliances on commodity architecture and IBM Power Systems. Even if they have never had IBM Power Systems in the datacenter, bringing the platform in today provides a powerful Linux system with significant processor benefits.”

Businesses with a Traditional Database and SAP Applications onIBM Power Systems

“There are many businesses that run their SAP business applications on IBM Power Systems with a traditional database, such as Oracle or DB2. For them, a move to SAP HANA (BW on SAP HANA, Suite on SAP HANA, SAP BW/4HANA, or SAP S/4HANA) involves their mission-critical processes and data. On the other hand, migrating to SAP HANA on IBM Power Systems will provide businesses with a significant database performance boost, easier administration and processing of vast volumes of business data, and faster user response time for transactional in-memory processing”

Businesses on IBM Power Systems That Currently Do Not Have SAP
“Many of these businesses prefer to remain on IBM Power Systems because they are invested and know IBM Power Systems, which makes migration easier. What’s more, once they have started a discussion to migrate off their traditional relational database management system (RDBMS), they are typically not looking to replace it with another traditional RDBMS. This essentially leaves them with two options: an open source database solution (e.g., EnterpriseDB) or SAP HANA on IBM Power Systems”

Businesses with On-Premises SAP Apps That Want to Expand Off Premises

“SAP expects its customers to move to a cloud or hybrid cloud model. Businesses can extend their environment to IBM Cloud using Power Virtual Servers. IBM Cloud provides a wide varietyof SAP-certified options for running SAP workloads, including IBM Power Systems. SAP infrastructure services are available in 58 IBM Cloud datacenters around the globe”

AIX Certification Preparation

There is a new certification in place for AIX admins and we would like with this post try to help you get a better grip of what you need to know and how to acquire the right skills to become certified.

There are different ways of learning stuff as always. Courses are one way but reading Redbooks and other documents could be a good alternative and/or complement. Most links are taken from the original landing page for the certification, but we’ve added a bunch of other good links that hopefully helps in your journey to become certified.

Cost advantages of running Red Hat OpenShift on IBM Power Systems

Download here: https://www.ibm.com/downloads/cas/26A6ONYL

This paper examines Red Hat OpenShift Container Platform (OCP) running on IBM® Power Systems as an effective platform for application modernization for a hybrid cloud environment. IBM tests show that the same multi-tier online transaction processing(OLTP)workloads on Red Hat OpenShift,running IBM WebSphere®Hybrid Edition on an IBM E950 Power System,can process 3.2x more transactions per second and can reduce the cost per transaction in a three-year TCO modelby 53%versus compared x86 servers. In addition to reducing IT costs, IBM Power Systems provide other benefits such as resiliency, security and scalability that are requisites for enterprise IT.
