Der Weg zu S/4HANA scheint unausweichlich… Auch wenn es bei manchem noch Jahre dauern wird bis man S/4HANA produktiv einsetzt. Der Weg dorthin wird entscheiden sein, besonders die Frage nach der Betriebsform: Intel, POWER oder doch in die Cloud? Das würden wir gerne mit Ihnen diskutieren.
Auf der CeBIT am SAP-Stand Halle 4, IBM Demo-Punkt können wir diese Themen mit ausgewählten Experten besprechen. Bei Interesse bitte kurze Info an mich.

Arbeitsgruppensprecher HANA on POWER
Thanks to two Students in Germany with a little help created this sympathic and easy-to-understand Video on HANA on POWER. Enjoy the viewing.

“The Bigmem kernel (kernel-bigmem) is an additional Linux kernel available for SLES for SAP Applications 11 SP4 customers through the maintenance channel.
The Bigmem kernel is modified to provide support for up to 32TB on IBM POWER. Customers using SAP HANA can optionally use the Bigmem kernel to support any size memory up to 32TB.
Customers who are using SLES 11 for workloads other than SAP HANA will continue to use the standard kernel.
Moving forward, both kernels will be supported by SUSE on SLES for SAP Applications 11 SP4.
– The standard kernel-default is only certified for configurations up to 1.5TB and should be not used for larger installations.
– The kernel-bigmem is only supported for SAP HANA environments when running SUSE Linux Enterprise Server for SAP Applications 11 SP4 (ppc64)
– The kernel-bigmem is NOT supported when running the standard SUSE Linux Enterprise Server 11 SP4 4 (ppc64) or for workloads other than SAP HANA.
The Bigmem kernel also increases the number of threads supported by SLES for SAP Applications 11.
This is required for systems that have more than 1024 logical CPUs such as an IBM Power System E880 configured with 192 physical CPU core with SMT8, resulting in 1536 logical CPU threads.
Also, note that clients implementing SAP HANA on SLES for SAP Applications 12 do not need the Bigmem kernel because the base kernel in SLES 12 already supports up to 32 TB of memory.”

Over 600 Customers ww are using HANA on POWER currently!
A large number of them are already reference customers like currently mentioned VEKA, other ones in the German speaking environment (D-A-CH) are e.g. BOSCH and COOP with large HANA on POWER installations.
If you need more information please contact us via PN, e.g. me:
