How did you get into the SAP HANA space?
I work in Deloitte, The Solutions Network (SNET) group, The SNET is an integrated Technology Center of Expertise that combines highly skilled technical resources with a series of data centers that help Deloitte consulting sell and deliver projects, manage investments, and enable the practitioners with the right skills at the right place at the right time. SNET resources provide consulting services and support for solution and client-related work from evaluation to project start-up through development, delivery, and support. We do all Co-Innovation, explore the product and the first one in Deloitte to get the hand dirty, and this get me focused in HANA when SAP HANA was released. As I has worked in BW accelerator in 2005 when it came out, so it was in-line and tempting to explore HANA and see how HANA is different, So, I started to play with SAP HANA on the first day when it was in Ramp-ups. I lead the HANA COE within my group and run the HANA training program to create next generation HANA resources, I work on HANA every day, and it would be suffice to say I breathe HANA every day. I still remember my installation on HANA SPS02. I got certified in HANA Technology on Dec 21, 2012. We have multiple instance of HANA running in our competency center – we have every flavor of HANA appliances, VMware and running ECC, BW, CRM, GRC, SRM, SCM etc. on HANA, with this you can understand we are well blended in HANA world
What advice would you give to people looking to learn SAP HANA?
HANA is the future, SAP is betting the company on HANA’s future success. HANA’s is do-or-die importance. So HANA is going to be around and not going to vanish, so take HANA seriously and read and read and read…. and whenever get opportunity get your hand dirty to build the confidence. HANA is not a rocket science, it pretty easy compared to other databases, and SAP has excellent material from help SAP portal and amazing blogs and documents, videos in SCN. Whenever you find good materials, never forget to make your hands dirty on it. AWS, Cloud share and Remote desktop are the sources for these. If you have knowledge of any database, the concepts are similar. So you already know half of it. You just have to get your hands around it. There are lots of HANA materials out there. Try open sap courses, SCN, saphana.com or search for HANA Academy in YouTube for many useful videos. Finally you need to practice and practice to enhance your confidence. Practice makes perfect. Reading materials and watching videos are theoretical and not enough, so doing practical is path to success.
Can you tell us a little about the projects you are working on right now?
I am currently on multiple project within Deloitte and client. Among all, the exciting one is Project RUBICON proof of concept (POC) Phase 2 – Production Workload for Virtualized HANA and Cloud Service Fabric in Hybrid Cloud Mode to show that the combination of tools can provide the performance “guarantees” of the physical appliance in a virtualized SAP HANA environment with Production workload. In Phase 1, we prove out that Disaster Recovery over long distance for virtualized SAP HANA is possible and provide real world metrics to customers. Showcase the benefits of Disaster Recovery for HANA via data replication using VMware SRM and Recover Point at a distance over 500km
Tell us about one of your HANA war wounds!
Honestly, I didn’t hit any major issue, but definitely have good amount of lesion learned, especially toward patching and upgrading to latest HANA revision. While updating the Hana DB from SPS8 Rev 82 to latest version (SPS 9 Rev 92) the installation stopped and prompt to install necessary operating system packages. If your operating system is on RHEL 6 or SLES 11 you would need to additional operating system software packages.Also had good learning experience especially toward performance tuning especially after Stack upgrade and running large complex report as hit the CPU utilization and Memory contention.
What do you see in the future of HANA?
HANA is the future and the way SAP is adding business value using Real-Time concept, Big Data & IoT, Next Generation Apps and openness. Adding all new concept like Multitenant Database Containers (MDC), Dynamic Tearing, and Lower TCO, simplified IT operations, decreased time-to-value for solution development, and increased agility. HANA is clearly the SAP’s top technology initiative and focus, its fastest growing database and the platform in the world and adoption. The pace it moving, I believe it will replace most of its competitors in the near future; and open more opportunities for the HANA folks in the market
If there was one change you could make to HANA, what would it be?
HANA should support other operating systems like AIX, Solaris, and HP-UX etc.
Also add wizard for workload or table distribution in HANA studio.
