Sweet, Simple . . . and Explosive?

Suite on HANA, Simple Finance, and a really cool explosion video as a bonus.

The recent parallel announcements of SAP Simple Finance and HP Converged System 900 for SAP HANA (CS900) motivated my blog on about the increasing business value of Suite on HANA and the ability to run such a mission critical system in a low risk fashion. The blog covers following topics in quite some detail:

  • SAP Simple Finance
    The blog explains the new SAP Simple Finance solution, the “trick” that it is using and the resulting business and IT benefits.
  • Customer Example: HP IT
    To put the move to SAP Business Suite on HANA into perspective, the blog gives a glimpse into the data sizing and preparation underway within the HP IT team.
  • HP ConvergedSystem 900 for SAP HANA (CS900) – see diagram below
    It also talks about the breakthrough HP CS900 system, the largest and most robust of its type with up to 12TB of RAM in a single system.
  • SAP HANA Datacenter readiness including comparison of storage and system level replication – see table below
    Most importantly, the blog busts any doubts that SAP HANA is not data center ready. With a broad offering of high availability and disaster recovery offerings from HP and other vendors, business continuity of SAP HANA is ensured; if need be in a fully automated fashion.

And the explosion? – A video shows a live datacenter failing over to a remote site within seconds, triggered by a small load of TNT.

For the full content, please read the detailed blog on – Kindly share your thoughts on SAP Simple Finance, HANA datacenter readiness, and HP Converged System 900 for SAP HANA and I will be sure to reply to your comments.

Picture: System family for HP ConvergedSystem 900 for SAP HANA

Storage Replication

System Replication


HP, IBM, Hitachi, CISCO, Dell, Fujitsu, NEC, VCE, Huawei, Lenovo (China only)

– HP ServiceGuard

– SUSE Linux Cluster (in beta)

Supported HANA use cases

– Scale-up

– Scale-out

– Scale-up

– Scale-out (only HP)

Replication strategies

– Synchronous

– Asynchronous

– Synchronous

– Asynchronous

Bandwidth requirements


–  Replication of partial transactions results in costly roll-backs when transaction is cancelled, e.g. due to failure


– No transmission of cancelled transactions; replication only after full commit

– Sync mode: only log files are transferred continuously with transaction commit, rest async driving lower bandwidth

Disaster recovery (*)

– Performance optimized:

– Cost optimized:

– Slow

– Slow

– Fast

– Medium


Hardware vendor dependent

Infrastructure agnostic

Additional capabilities


– Zero downtime management (aka NetWeaver connectivity suspend)

– Cascading multi-tier system replication (only HP)

Key roadmap capabilities


Active/Active Operation (read only reporting on secondary fail over site)


Performance optimized

– Secondary system completely used for the preparation of a possible take-over

– Resources used for data pre-load on secondary

– Take-overs and Performance Ramp shortened maximally

Cost optimized

– Operating non-prod systems on secondary

– Resources freed (no data pre-load) to be offered to one or more non-prod installations

– During take-over the non-prod operation has to be ended

– Take-over performance similar to cold start-up

    • John,

      Great to see you read my blog and thanks for the question.

      With HANA System Replication being a HANA capability and not one of HP Serviceguard, it is not limited to HP of course. However, HP was the first vendor to take advantage of it and build a cluster based offering for fully automated failover it in the market. Most importantly, it is being used productively by countless customers and is continuously being improved based on their feedback.

      With Serviceguard being a highly mature tool (it originated in the UNIX world) that has been in the market for a long time, it has enabled countless HA/DR scenarios across a variety of solutions and underlying technologies. With configuration, it can be tailored to the stack.

      While Serviceguard support focuses on HP infrastructure, technically, the integration to SAP HANA via System Level Replication abstracts it from the underlying hardware to a large extend. It is conceivable to take HP Serviceguard and configure it for 3rd party infrastructure. - In fact, some prominent infrastructure and HP competitors approached us at Sapphire to OEM Serviceguard for their use and customers.

      Let me know if you like to find out more about Serviceguard. Happy to get you together with our product manager for the solution.



      • No worries and good that you guys at HP are educating the market. It would be good to see some more technically focussed blogs explaining how it works in detail for the SCN audience. They like that stuff.

        Got it, and this makes good sense. However the framework for automated takeover is based on SUSE Linux capabilities - see so all hardware partners can take advantage of this including the automation. That's not an HP-specific capability either.

        It sounds like HP are extending the HANA automated DR with ServiceGuard, which especially for customers already using HP and ServiceGuard elsewhere in the organization, will be a nice-to-have addition, especially if you are monitoring large and complex environments. I presume it allows things like centralized management and monitoring of large clusters, which is certainly a good thing.

        • John,

          Yes, you are correct about SUSE's capabilities. Please have a second look at my table above and you see them listed in my tabular comparison as part of the blog.

          What you need to know however is that this offering was just recently announced by SUSE to the market and therefore SUSE Linux Cluster does not combine the years of experience HP has in this field and the countless successful customer deployments.

          We will follow up with more detailed information on HP Serviceguard. For now, here is a technical spec sheet for the offering:
