New strategic relationship allows HDS to move data directly from SAP ArchiveLink into HCP

 

 

This Solution with the PBS connector  will allow HDS to offer to their customers a way to archive data from SAP ArchiveLink.    PBS Content Link with Hitachi Content Platform allows customer to archive SAP files, documents, print lists and others is to provide a lean and very effective solution to link customer’s SAP environments with HCP.  The purpose is to support customer's business and functional requirements in the domain of SAP document archiving.

 

With SAP Archive Solution (PBS Content Link) you can create a direct and lean connection between SAP systems and Hitachi HCP and in this way enable archiving that meets legal requirements and a future-proof Information Lifecycle Management concept. PBS software is installed on an intermediary server that sits between SAP and HCP.

Archiving SAP Content Using the Hitachi Content
Platform and PBS Content Link

 

 

Overview:

 

SAP application customers face the challenges of ever increasing reliance on unstructured content, growing database sizes with resulting performance impacts and data retention requirements for regulatory and governance compliance.  The combination of Hitachi Content Platform and PBS Content Link is the ideal storage foundation for addressing these challenges. 

 

The Use Case for SAP Content Link include several scenarios including the following:

  1. Reduce database size and improve performance through data archiving
  2. Manage information retention in live SAP systems
  3. Retire legacy systems while preserving retention-relevant information
  4. Retain data required for regulatory and tax purposes

 

Solution:

 

The objective of SAP Content Link with Hitachi Content Platform to archive SAP files, documents, print lists and others is to provide a lean and very effective solution to link customer’s SAP environments with HCP. The purpose is to support customer's business and functional requirements in the domain of SAP document archiving.

 

With SAP Archive Solution (PBS Content Link) you can create a direct and lean connection between SAP systems and Hitachi HCP and in this way enable archiving that meets legal requirements and a future-proof Information Lifecycle Management concept. PBS software is installed on an intermediary server that sits between SAP and HCP.

 

How it works:

 

The PBS server has a WebDAV interface to terminate ILM 3.0 traffic, and redirect it to HCP using our rest protocol. The PBS software doesn’t save any information; it’s stateless, and commits writes only when HCP commits them.

 

PBS Content Link also simultaneously supports the new SAP-specific WebDAV 3.0 protocol in addition to the already well-established SAP ArchiveLink interface.  PBS Content Link has been certified by SAP for the integration scenario BC-ILM 3.0 (Information Lifecycle Management for SAP). The WebDAV protocol ensures the usage under the SAP ILM components Retention Manager and Retention Warehouse.

 

PBS Content Link software (Archive Server) runs as a service on major platforms (Windows, Linux, AIX, Solaris) using the platform specific webserver as the underlying engine (IIS for Windows, Apache httpd on the *NIX platforms).

What makes HCP a great archive platform ?

 

In the era of multi petabyte data sets, full backups become ever harder to achieve.  Moreover, many business applications dictate that vast amounts of information be accessible 24x7 with minimal latency,  and resilient to both routine and catastrophic equipment loss.

 

HCP provides the building blocks to construct a storage cloud that never needs backup.  Using clustering and replication technologies, it provides applications a secure repository that ensures data validity, durability and availability. Applications like Content Link enjoy scalable performance by using REST ingest protocol.  All HCP nodes contribute during data ingest phase, maximizing throughput and overall archive performance. Cryptographic hashing computations made by HCP guarantee integrity of stored data and eliminates worries that your restored bits won’t exactly match your stored bits.  HCP is constantly rechecking these hashes and self-repairs any defects that might develop over time.  When setting up ContentLink with HCP, you’ll have several choices for backend data storage that include local disks (RAID6), Fibre-channel arrays (RAID6), or trays of commodity disks protected with EC  (erasure codes).  The last option protects images with storage durability mathematically computed to exceed 15 9’s.  HCP accomplishes this feat with large spindle, plane-Jane desktop drives with the economic attributes we all love: low $/GB.  In all cases, availability can be further increased by having HCP replicate data to one or more remote sites, that can reply on behalf of a failed site in milliseconds.  And finally, HCP also offers compliance options that make it impossible to accidentally overwrite or delete important data.

 

Why makes Content Link a good fit for HCP

 

PCL runs without any database, and thus requires very little administration. A dedicated caching option improves the access performance for SAP archive files (ADK). In addition to file and data storage, PCL includes an effective research option that supports dedicated analysis and file/data search. PCL is SAP certified and many customers worldwide benefit from its economical and effective features.

From a logical point of view, they are completely stateless – the only thing they store locally is a set of two config  files – one that holds all the settings, the other one holding encrypted user credentials (for SAP and for the storage component in use, i.e. HCP). SAP metadata is stored along with the object to which it belongs on HCP (but not as Custom Metadata).

 

Under specific circumstances, they store some additional metadata, but use SAPs own database for it.  By doing so, it is very easy (and extremely quick) to replace a failed server – just install the service on a new server, copy over the (backup’ed) config files and you’re up again.  As their resource demand is so low, they can run on low end server hardware (or virtual machines). The only requirement they have is good network connectivity. 

 

 

 

HDS & PBS Partnership

PBS & HDS have formed a strategic relationship to allow for HDS to resell the PBS Content Link solution and related Maintenance Services. Further, PBS Content Link and Hitachi HCP provide an excellent combination to have customers connect their SAP environment to a state-of-the-art fix content storage system (HCP) to store SAP archive files, documents, print lists etc.
