CIBER Managed Services GmbH built a dynamic Cloud Infrastructure for SAP landscapes, based on a combination of IBM server, storage, database, and system management software. The new storage infrastructure, which consists of the IBM XIV Storage System and IBM SAN Volume Controller, offers individual service classes to suit different customer needs, maximizing operational efficiency and minimizing expenses. The SAP application landscapes run on both IBM Power Systems servers and IBM System x Blade Server technologies.

    • “Through the 100 percent virtualization you gain a dynamic infrastructure and you get the ability for an easy billing system.” Carl-Philipp Müller Lead Sales Operations Services CIBER Managed Services GmbH“XIV is simply amazing. The usage of XIV real time copy, which is able to copy many terabytes of data very fast, reduces the downtime for provisioning drastically. The main focus as a service provider is the sector of customer satisfaction, which is especially improved by the usage of the new XIV system.” Markus Peltz Data center Manager CIBER Managed Services GmbH

    • IBM Power Systems landscapesTypically, for larger customers CIBER hosts SAP ERP and SAP The VIOS provides full virtual paths from each LPAR to theNetWeaver applications on IBM Power systems. For existing switched fabric in the data center. Switched fabric networkclients, CIBER has two IBM Power 560 and two IBM Power 750 topology allows nodes to connect with each other via one orservers, running the IBM AIX operating system and IBM DB2 for more network switches, which provides both high total capacityLinux, UNIX and Windows. and a high degree of resilience if a network switch fails.LPARs are subsets of a computer’s hardware resources, CIBER has assigned a separate LPAR for storage management,virtualized as a separate computer using the hypervisor. A with a dedicated Converged Network Adapter to supportphysical machine can be partitioned into multiple LPARs, each concurrent LAN (TCP/IP) and SAN (FCoE, iSCSI) traffic over ahosting a separate AIX operating system. The hypervisor shared 10 Gb Ethernet link. CIBER currently uses only TCP/IPassigns a specific range of virtual processors to each of the and iSCSI protocols, and wants to be ready for FCoE in theLPARs. CIBER does not configure dedicated assignments of future.processors, and shares uncapped processor resources acrossall the LPARs. PowerHA for AIX (previously named High Availability Cluster Multiprocessing HACMP) provides high availability of logical partitions (LPARs) in a two-node cluster by way of automatic failover. When one server node goes down, the other server node takes over. Depending on clients’ requirements, most production systems and some of the quality assurance systems running on AIX use PowerHA to ensure continuous availability.For large SAP systems, CIBER prefers to use POWER CIBER uses IBM Virtual I/O Server (VIOS) to enable the sharingtechnology and virtualization over VMware vSphere. This is for of physical I/O resources between client logical partitions withintwo reasons: first, because AIX LPARs can scale to higher total the server. The total physical bandwidth can be allocated in fixedprocessor and memory limits; and second, because AIX amounts to each server, or policies set to enable full capacity toenables much higher processor utilization. By using AIX LPARs, be used by high-priority workload at peak times.the SAP application can grow much larger before it is necessaryto scale-out over multiple servers.The migration from IBM POWER5 to POWER6 and POWER7 waswithout any problems, CIBER simply connected the new serversto the SAN storage system and restarted the new servers and theSAN storage system. 11
    • Storage architectureCIBER implemented an enterprise-class storage solution, based At the core of the storage landscape are two IBM XIV model A14on two IBM XIV enterprise storage systems, IBM SAN Volume storage systems, each equipped with 79 TB storage. The XIVController (SVC) as Split I/O Group, IBM System Storage DS3400 systems act as the principal SAP application data storage.for the SVC quorum disk, and IBM Tivoli Storage Manager. The CIBER can handle almost three-fold storage growth as customerstorage infrastructure has been designed to provide a data volumes grow. In practice, Tivoli Storage Manager enablescombination of performance and resilience, as well as the ability sophisticated management of data, moving archive and lessto allocate storage volumes to multiple customers exactly as their active data onto tape, to help reduce the need to expand diskneeds dictate with the least possible administration and systems.expense. CIBER evaluated different solutions and chose XIVtechnology because of better IO performance, improved CIBER implemented the two XIV systems, located at the primaryadministrative handling, and easier maintenance support than and secondary data centers. XIV technology offers high,its competitors. consistent performance and hotspot-free service due to mass parallelism and the distribution of logical volumes across all hard disks in the system, eliminating distribution planning.

Combined with automated SAP post-processing, DB2 also offers close integration with Tivoli Storage Manager,CIBER is able to create a completed cloned SAP instance in providing a comprehensive backup solution that protects DB2about 30 minutes. XIV Snapshot gives CIBER the ability to and related data reliably and cost-effectively.respond to customer demands in ways and at a speed that evenin recent years would have been impossible to achieve. The new index compression feature within DB2 is the next step to improve database performance and reduce storage costs. InIn selecting XIV systems, a new technology for the CIBER team, addition, compression for temporary tables for SAP systems isthey soon discovered that only three hours’ training was needed activated ‘under the cover’ to reduce disk costs.

    • Automatic provisioning of SAP with Cloud servicesAutomatic reorganization offers time-saving advantages for CIBER’s ultimate goal is to deliver Cloud services to itsdatabase administrators, because it checks if a reorganization of customers, which means being able to provision, upgrade anddata and indices is needed and if so, the Reorg utility is clone SAP instances very quickly using automated systems.automatically called and reorganizes the data and indices in thebackground.

To clone SAP instances, CIBER uses XIV point-in-time copy.To do so, CIBER used the “Sampled” option, which comes with CIBER clones (snapshots) the entire SAP system, including EXE,the R3Load Version 7. This option causes every ‘N’th row of the DATA, and LOG files, while keeping the SID.
