SAP-HANA --> HA, Replication or Replacement?

SAP-HANA's SCALABILITY

Yesterday Dr Hasso Plattner demonstrated SAP-HANA's scalability feature with the help of 100TB SAP-HANA system built by IBM in just 2 weeks. Amazing. SAP once again proved it can deliver innovation as promised in just a little more than 2 years. And while doing so, SAP also demonstrated the value of partnership and what they call co-innovation with partners and customers. Nice job.


SAP-HANA's HIGH AVAILABILITY

Frankly speaking I was not impressed with HA demonstration however. Several details are missing.

• How much data was in nodes 5 and 6;did they contain 1TB of data each or was nearly empty?If it contained 1TB of data, the time it took to failover was just impressive. Incredible.
• How long it would take for standby nodes 7 and 9 to load data from the disk.(if failed nodes contained 1TB, then this question is redundant).
• Why they chose to use 100TB SAP-HANA server to demonstrate HA? With 1TB SAP-HANA, would HA work when all nodes(1 node in 1 node server) fail?
• The demonstration showed the failover was not instantaneous. It actually took a while; the speaker told us it would be transparent to the users. What did he mean by that?

At any rate, HA demonstration IMO raised more questions than providing answers.

SAP-IBM PARTNERSHIP
IBM in their website http://www.ibm.com/solutions/sap/us/en/landing/hana.html states:

"...Customers who work with IBM and SAP can benefit from years of joint product development which allows our offerings to be integrated for easier implementation. This is true of IBM’s DB2 database which is tightly aligned with SAP HANA for seamless replication of data,...."

DB2 database which is tightly aligned with SAP HANA for seamless replication of data?? SAP states SAP-HANA would replace legacy databases such as Oracle, DB2 etc. In that case, why seamless replication of data with DB2 matters? 

When SAP-HANA starts replacing legacy databases, wouldn't that affect SAP-IBM partnership? Should customers who want to invest in IBM's SAP-HANA be concerned? 

Is SAP-HANA is going to replace or contain replicated data from legacy databases? I wish we knew the answer.

In addition, SAP on Sunday, 05/13/12 - the day before SapphireNOW began - was trying to send a message they wanted to be #2 DB vendor by 2015. In an hour or so later, they decided to withdraw that message. This happened in San Francisco event 2-3 weeks earlier. Since SAP-HANA was touted as Game Changer, most innovative solution in 4 decades of RDBMS existence, that message seemed logical and reasonable. I wonder why they decided to withdraw!
