IBM Investment in Linux (hint: it started early)

Our investment✓ Late 1990s - Involved with creation of Apache Software Foundation and the Eclipse Foundation✓ 1998 - IBM announced it would ship the Apache web server with the IBM WebSphere Application Server✓ 2000 - $1B Linux investment to make Linux a reality✓ 2013 - $1B Infrastructure investment to wrap the openness of Linux around Power Servers

17,000 coders in 37 countries✓ 2018 – Regain World #1 and #2 fastest Super Computers with aid of NVIDIA and Red Hat (and maintained for 2019)✓ 2018 – Expanding Partnership with Samsung✓ 2019 – Red Hat Acquisition (A few $Billlion)✓ 2020 - Utilizing Summit and Sierra to break down cause and solution for COVID-19

•our Java runtime, J9, contributed to the Eclipse Foundation as the Eclipse OpenJ9 incubator•our OpenLiberty runtime for Java EE and MicroProfile applications, contributed to openliberty.io•our open blockchain project to Hyperledger as Hyperledger Fabric•our serverless platform to Apache OpenWhisk•our quantum computing API Qiskit•our AI Fairness 360 Toolkit (AIF360) and AI Robustness Toolbox (ART)•analytics projects such as the code that became Apache Toree and Apache SystemML•and over 100 others in just the past 3 years

IBM has made many major contributions to open source, including:

Linux on Power Benefits

➢ Linux on POWER uses 64k page sizes. This translates into an advantage on moving larger data sets from physical memory, when compared to Linux on other architectures using smaller page sizes (such as 4k), since it:

➢Moves data in larger chunks at oncewhich is even more enhanced by the typical larger memory bandwidth rates on IBM POWER Systems.

➢ Less Overhead: Decreases the overall cost of creating and maintaining larger processes memory. CPUs, and by extension Operating Systems such as Linux, employ mechanisms (ie address translation) in order to relief general applications from having to "deal" with physical memory positions and how those get allocated. By splitting memory into larger chunks, there is less overhead required to store those translations mappings.

➢ Speed-up: Increased probability of cache hits.Likewise, these translation mappings are frequently cached within processor cores, for speed. These caches are typically small, due to cost and space constrains within the chip. By having to deal with a small set of translations entries, there isan increased probability a certain mapping will already be cached and therefore spare precious processor cycles during load/store and instructing fetch operations.

Linux on Power Benefits

➢ Higher Thread Count: Fully enabled for POWER processors higher hardware thread count (8), which translates to more simultaneous logical threads of work per core.

➢ Larger memory Capacity: Fully tested and tuned for larger memory capacities provided by POWER servers, such as 64Tb.

➢ Advanced RAS: Enabled for advanced RAS capabilities found in POWER Servers, such as recovering for fatal errors in PCIe adapters (EEH), or platform system dumps for capturing critical debug information.

➢ Tuned Deterministic Capabilities: Linux on POWER is enabled and tuned for the deterministic capabilities provided by the IBM PowerVM hypervisor, allowing for more critical workloads to share the same server, without the risk of disrupting each other.

Linux Distributions on Power Systems (pre Red Hat Acquisition)

Linux Distributions on Power Systems (post Red Hat Acquisition)

Stream will contain the code under development for the next minor RHEL release, which will allow the developer community to discuss, suggest, and contribute features and fixes into RHEL more quickly.

Red Hat introduces rolling release CentOS StreamBy Steven J. Vaughan-Nichols for Linux and Open Source | September 24, 2019 -- 15:30 GMT (08:30 PDT)

According to Chris Wright, Red Hat's CTO, is it's "a developer-forward distribution that aims to help community members, Red Hat partners and others take full advantage of open source innovation within a more stable and predictable Linux ecosystem. It is a parallel distribution to existing CentOS."

CentOS Stream is an upstream development platform for ecosystem developers. It will be updated several times a day. This is not a production operating system. It's purely a developer's distro. Wright encourages, "users that want to be more tightly involved in driving the future of enterprise Linux, however, to transition to CentOS Stream as the new 'pace-setting' distribution."

"The CentOS Stream project sits between the Fedora Project and RHEL in the RHEL Development process, providing a "rolling preview" of future RHEL kernels and features. This enables developers to stay one or two steps ahead of what's coming in RHEL."

Enterprise License Agreement (All You Can Eat)

IBM Systems TechU © Copyright IBM Corporation 2020 15

An Enterprise License Agreement (ELA) is an agreement to license the entire population of an entity (employees, on-site contractors, off-site contractors) accessing a software or service for a specified period of time for a specified value.

ELA for Linux Distributions (Red Hat and SUSE)❑ Must be a large deal for the Linux Distro! Think in the lines of >$1M per year worth of Distro

offerings❑ There is no set one size fits all deal. Each deal is a unique opportunity and agreement

❑ For an ELA with Red Hat, IBM Sales/Partners should work directly with the Red Hat Sales team to determine if the potential deal qualifies for an ELA. ✓ This is a new opportunity with Red Hat as they did not allow ELAs with IBM Power until

recently

❑ For an ELA with SUSE, IBM Sales/Partners should work directly with the SUSE Alliance Director for Power Brand (Alex Boro alex.boro@suse.com)

Increase SAP HANA uptime with Virtual Persistent Memory

Faster SAP HANA shutdown*

*The >17x improvement in SAP HANA startup time and 30% faster SAP HANA shutdown time with Virtual Persistent Memory are based on our internal tests with POWER9 system 9040-MR9 that has 48 cores and 8 TB memory. Configuration details for comparison test with POWER9 firmware level equal or greater VM940_FW940.00 (27) – 4TB main memory compared with 512MB main memory and 3584MB virtual persistent memory. Both configurations included following SAP HANA db VMs - 1 x SAP HANA database server with 28 dedicated cores and 512 to 4196 GB main memory, 1 x SAP Netweaver Application Server with 16 ded. cores and 512 GB main memory

Intel Optane DC Persistent Memory (DCPMM) IBM Virtual Persistent Memory (vPMEM)

Separate DCPMM module need to be purchased Additional hardware is not required

Available only on Intel’s Cascade lake architecture All existing POWER9 Servers with PowerVM support Virtual PMEM

Different module used which has higher latency as compared to DRAM. Preserves the same run-time performance

SAP HANA is not yet supported by SAP on vSphere on persistent memory

Built using Virtualization, virtualization with same granularity supported for SAP HANA

Data is preserved even when power is off.Virtual PMEM does not preserve memory across server power down. But it will preserve the data if you reboot your HANA, Linux OS

Specific deployment ratio needs to be followed between DRAM and PMEM when configuring HANA database. (SAP Note 2786237)

No ratio restriction applies using Virtual PMEM

Intel Optane versus IBM Virtual PMEM – Major Differences
