Hewlett-Packard revealed Oct. 4 that it is developing a new disaster-tolerant appliance for SAP's HANA in-memory database, claiming it to be the first of its kind in the market.
With an HP AppSystem certification, users will be able to deploy a HANA appliance that is supported by SAP for business scenarios in which real-time recovery during server failures is required.
The HP AppSystem allows an IT admin to host a second HANA system that can take over in the event of a significant outage. The system was tested to ensure that HANA services are continuously available by supporting rapid recovery with no data loss.
HP said it is the only vendor certified by SAP for this capability.
The DT failover is in all cases a manual decision by the system administrator (HP and users would not want it any other way). There are manual steps -- detailed in the user's runbook -- that must be performed in case of a failover, although some pieces can be automated with scripting.
HP’s DT package makes use of an integrated data replication solution using the X9300 IBRIX Network Storage System and Continuous Access software, a feature of the HP P6000 series disk array included as part of the shared storage infrastructure in HP’s scale-out HANA architecture.
CA provides site-to-site replication for data written to a P6000 series disk array. This is the first solution certified by SAP makes use of CA in synchronous mode, which provides robust, metropolitan area, data replication for distances up to 50 kilometers or 30 miles.
In-memory computing will at the same time let businesses simplify their IT infrastructures by reducing the need for data caches and similar technologies.
HANA is one of the foundations of SAP's overall strategy, which also includes cloud and mobile computing that recent acquisitions Sybase and Syclo bring to the company.
HANA has four parts: the database software itself; HANA Studio, a suite of tools for modeling; HANA Appliance, which is the DB installed on partner-certified hardware as an appliance; and HANA Application Cloud, which is the cloud-based infrastructure for delivery of applications. Typically these are existing SAP applications rewritten to run on HANA.
Testing is now under way for an asynchronous DT solution -- also based on CA -- that will provide data replication for data centers that are 500-plus kilometers or 300-plus miles.
HP said the new appliance should be ready for prime time by the end of the calendar year and that it anticipates the certification for the asynchronous solution to follow.
