Welcome to this Ask the Expert conversation. In this session we’ll bring the best and most experienced experts from around the world to respond to all the questions you may have about SAP HANA TDI, EMC solutions for SAP HANA TDI, implementation rules and details.
SAP HANA, still being a young technology, is evolving and maturing. A sign of this maturity is the increased deployment options it increasingly provides. SAP HANA Tailored Datacenter Integration represents the future of SAP HANA, bringing unprecedented levels of openness and flexibility to SAP HANA datacenter integration. This increased openness represents a critical enabler of customer’s decisions to move from a PoC phase towards making SAP HANA a mainstream component on the datacenter architecture. Nevertheless, there are still a lot of miss understandings in regards to what is SAP HANA Tailored Datacenter Integration, its rules and possibilities and we hope that this ATE session will help bring clarity.
There are no forbidden questions on this session, so do not miss this unique opportunity to get your questions answered.
Meet Your Experts:
Global SAP HANA Technical Architect - SAP HANA
Antonio has been working with SAP Systems since 1997, having performed such diverse roles as SAP Basis Consultant & SAP Systems Architect advising customers on technology selection deployment, transformation and operation based on the specifics of their business, SAP Basis Team leader for customers in the Banking, Insurance and Telecom Industries, IT Operations Manager in the Retail Industry, as well as SAP Practice Manager and Director of Strategy on behalf of IT Providers, and SAP Basis trainer for SAP, teaching SAP Basis/NetWeaver certification academies and other SAP Systems Administration courses.
Solutions Product Manager - SAP HANA
Allan has been working in IT for over 30 years as a mainframe Systems Analyst and Software Engineer. Since 1997 he trained as a SAP Basis Administrator for a global SAP roll-out at a fortune 100 company. Later Allan transitioned to International SAP Consultant for SAP Technical Core Team (TCC) managing and executing customer on-site Performance and Stress Testing for critical escalated SAP go-lives in retail, insurance, telecommunications, and manufacturing. Since 2005 he has been working at EMC with current role as a Pragmatic Certified Solutions Product Manager driving the SAP HANA Solutions Roadmap.
Global Practice Manager - SAP HANA
Working with EMC Systems since 2000, having started as a Oracle and Informix DBA, Sean moved into EMC supporting applications on EMC storage for the Midwest Enterprise teams. From there he added SAP, Microsoft and DB2 knowledge. In 2010 Sean was asked to come work for a hush hush project that was going to change IT, this became what we know as CI and VCE was born. Sean brought his application knowledge into the new team, and then also added lab management and the ability to physically build Vblocks from the ground up. In 2010, he move back to the services side, by taking on the global role of setting up and providing PS solutions for Applications and Big Data on Vblocks. This has most revolved around SAP HANA and the odd backoff against Exadata.

>> Join our Ask the Expert: SAP HANA TDI with EMC - Implementation, Rules and Details http://bit.ly/1Npqbe3 #EMCATE <<
This ask the expert session is now open! All questions are welcome.
Just post your question as reply to the main message on this threat, and myself alongside my colleagues moderating this discussion, will come on a regular basis to provide you with responses.
This discussion will be open for 2 weeks as of today, and we'll welcome any questions in relation to SAP HANA Tailored Datacenter Integration, SAP HANA virtualization, and SAP HANA in general.
Be also aware that we will be hosting a high level session on SAP HANA TDI at SAPinsider on the September 17th, and all questions on details will be able to be answered here.
Note that on the moderators team, together with me we have our colleague responsible for all SAP HANA deployment services in VCE so with a welth of implementation experience, and our colleague responsible for EMC's engineering roadmap bringing a unique perspective from solutions engineering.
So, looking forward to answering all questions you may have on this topic.
Hi, I was in a customer discussion today and was asked if HANA TDI applies only to certain SAP applications or if TDI based HANA systems can be used for any SAP application. Can you comment?
Posting a questions on HANA TDI. Few are more general to SAP.
1) Any plan to support SGI TDI with any standard HA configuration ? Their HA uses DT instead.
That's a question we keep getting, and also yesterday one global service provider asked the same.
The simple answer is that the TDI rules apply regardless of the SAP application or the size of the SAP HANA node, as its SAP that defines the rules, and that's how SAP has defined it.
But going deeper, I believe the question keeps popping up because the simple answer I gave above, doesn't match the "gut feel" of all those experienced architects that have been designing SAP systems for years new.
Why? Our experience shows us that the "right infrastructure requirements" for a certain SAP application is a factor of the number of users, number of interfaces, batch workload and database size. So, in our minds it seems wrong that the TDI rules are the same regardless of all these factors.
We need then to look at the SAP HANA TDI rules as a guideline for certification.
SAP HANA, being still such a young product, still lacks broad experienced resources in the market.
SAP by defining these rules, is defining a baseline from which the customers can build systems and where performance will not be a major challenge. So, these rules are a starting point, as once the application is in production, its up to the customer to monitor it and administer it, and adapt the allocation of resources to its actual needs.
In summary: look at this TDI rules as a "safe starting point", as a guideline. Not as a hard rule written in stone.
There are many options for HA configurations.
Obviously the SAP supplied options for hot/warm standby being one.
SuSe Linux has it's own HA capabilities, in fact SuSe now do the certification of
all HA products that work with SAP as announced last year at SAP Tech'ed.
If you have EMC storage then there are multiple options for DR as well,
e.g. recovery point, SRDF, VPLEX
Large memory size means need fast restart times and time to read storage and load into memory without waiting for hours. From a HANA Roadmap we are looking at standard SAP System Replication for local HA (instaead or in addition to remote DT) to meet the high RTO needs. EMC value is the expectation that XtremIO on HANA for local HA saves 50% of the storage footprint on top of the normal compression/dedupe XtremIO savings. With EMC and XtremIO on HANA combining best of SAP and EMC get great restart times and low storage need. Will also look at restart with just XtremIO. We hope to quantify and report by early Q1.
Hi, can you speak about EMC ScaleIO as a TDI solution for SAP HANA? Is it viable? Is there customer interest? If not, why?
