SAP Hanna Dynamic Tiering product road map for BWonHANA or BW/4HANA

415 Views Last edit May 18, 2018 at 08:17 PM 3 rev

All - I need some clarification here and appriciate your help.

SAP HANA with dynamic tiering consists of two types of hosts:

 Regular worker hosts (running the classical HANA processes: indexserver, nameserver, daemon, xsserver,…) – HANA hosts can be single-node or scale-out; appliance or TDI

 “ES host” (running nameserver, daemon, and esserver) – esserver is the database process of the warm store. This statement is from HANA DT Implementations detail and road map document.

Now when I look at the BW4HANA product roadmap, It indicates that DT is not supported for BW on HANA or BW4/HANA.

If I look at HANA 2.0 product roadmap. Dynamic tiering is supported with all HANA database implementation and there is a upgrade path from HANA 1.X to HANA 2.0. This means if we have DT 1.X installed, we can upgrade it once we are upgrading HANA to 2.0.

If I look at the upgrade road map to BWonHANA or BW4HANA, it runs on NW stack 750+ and Hanna 2.0 which supports DT 2.0.

I am having issue understanding how is that DT 2.0 is not supported with BWonHANA or BW4 Hana if it is part of the upgrade road map ?

Regardless of the BW version or stak, Once the BW is installed, all the tables are available in Hana database. I can move some or all of the selected tables to DT.

With that in mind, How is the architecture in BWonHANA or BW/4HANA is changing which impacts the DT support ability?

Hana extension nodes are not cost effective and it is not reducing the Hanna memory foot print. How is extension nodes are being compared to DT?

Best regards

Looking forward for your input.
