    CA
    File System Manager

    Storage system support: File System Manager supports a wide range of file systems (not designed for PC and workstations).
    Application support: Designed for file systems only; does not include support for applications.
    Migration features: Organize data and storage resources that span multiple systems into logical groups using access frequency, file size and type, storage cost, model, etc. Drive file movement, copy and deletion actions across multiple systems based on established classifications and policies. Automatically migrate data from primary storage to secondary or tertiary storage while maintaining transparent end-user access. Automate storage consolidation from initial planning to transparent migration of end user files and directories. Enable administrators to simulate data management policies before actual execution in order to better understand their scope and effectiveness.
    Data cleansing features: Uses the native deletion process available on the supported operating system/storage platform.
    Data collection features: Agent-less approach for data collection eliminates the need to install and maintain server agents. The administrator configures the software to scan each server and NAS device in the network utilizing industry-standard protocols (CIFS, NFS). Data collection process can be manually launched by administrator on a select group of servers or it can be done on a regularly scheduled time interval. File System Manager collects information on total available and used capacity by servers, by volumes, and by exports/shares, as well as at the file level for information such as size, file type, owner, creation date, last modified date and last accessed date, path and user group information.
    Management features: Modular design allows existing policies to be dynamically updated in case data and/or storage resources have changed. This approach is based on the creation of logical groups that represent business value or ownership of the data. For files owned by one department, any new data matching that criteria automatically becomes a part of that group and can be operated on by a policy. Group resources are also "global" in nature, allowing data or storage from multiple servers to be logically associated.
    Automation features: Policy Automation Engine executes the data management actions. Unlike any other policy-based solutions, it uses a patented algorithm to select files for movement based on detailed parameters such as age, size, last modified, last accessed date (among others), combined with the business valuation that the administrator specifies.
    Operating system: Windows 2003, 2000, NT 4.0; Sun Solaris 2.6, 2.7, 8, 9, 10; HP-UX 11, 11i; IBM AIX 4.3.3, 5.x; Red Hat Linux; SGI IRIX; NetWare 4.x, 5.x, 6; Mac OS X; NetApp Storage Appliances; EMC Celerra, Centera; NAS devices
    System requirements: Windows server, dual Pentium class 1GHz or greater speed processors, 80 GB free disk space, 1GB DRAM, 10/100 Network Adapter (or better).
    Implementation: Design of the architecture – based on storage platforms, network topology, target storage configuration; Installation of server hardware and CA FSM software according to architecture; Definition business goals and creation of policies that support goals; Testing of limited data – end to end and retrieval; Staged deployment of polices to accommodate network and capacity constraints.
    Interoperability: NetApp Storage Appliances, EMC Celerra, EMC Centera, Hitachi HCAP
    Base cost: Pricing ranges from $14,000 to $40,000+

    Migration features: Guaranteed capture, routing, transformation, delivery, and verification of transactional data across heterogeneous environments in real time. Decoupled architecture allows each component to perform its tasks independently of the others, while also enabling heterogeneity between source and target. Ensures high availability and scalability for mission-critical applications as transaction loads increase.
    Data cleansing features: Provides various conflict detection and resolution options to provide the necessary flexibility and adaptability for a range of requirements. Conflict detection and resolution options can be implemented globally, object-by-object, based on data values and complex filters and through event-driven criteria including database error messages.
    Data collection features: Resides with the source database and looks for new transactional activity that occurs. This reads the result of insert, update, and delete operations by directly accessing the database's transaction (redo) logs, and then immediately captures that new data for distribution. It moves only the committed transactions (intermediate activities and rolled-back operations are filtered out), which not only reduces infrastructure load but also eliminates potential data inconsistencies.
    Management features: Gives customers control of the processes at each node. Provides a variety of administrative, housekeeping and reporting functions for those processes. GUI monitoring, configuration and management components allow you to set up alerts and notifications if there are any issues or latency involved in the data movement.

    System requirements: Implementation: Consists of decoupled components that can be configured to enable a variety of solutions for high availability/disaster tolerance and data integration. This architecture allows each component to perform its task independently. The implementation is straightforward; customers can be fully deployed in hours.
    Interoperability: Can co-exist with a physical replication solution or a SAN such as SRDF. Many customers utilize high availability solution in conjunction with this as an added "insurance" that their systems never experience downtime. It can perform system (application, hardware, OS) migrations with minimal downtime, and the ability to roll forward and back via proprietary trail files allows the customer to pick up where they left off (if there is any system outage).
    Base cost: Starting price for GoldenGate is approximately $60K. This would be one capture and one delivery on a midsize CPU server.

    Incipient Inc..
    Network Storage Platform (NSP)

    Storage system support: Supports non-disruptive data migration of SAN-based storage.
    Application support: Supports any application accessing data in a SAN environment. Customers implement iNSP on a wide range of applications (custom and off the shelf) and databases with no plug-in or custom integration required.
    Migration features: Application data can be migrated non-disruptively, eliminating the need for scheduled downtime and shortens the planning effort. The application server sees the same volume before and after the migration, eliminating SAN reconfiguration and host software (HBA firmware, Multipath) updates or changes. Automated, policy-based provisioning of destination volume resources which simplifies the operational challenges associated with data migration. Manage migration priority to eliminate resource contention.
    Data cleansing features: This is a network volume level data migration solution designed specifically for block-based storage. It has no visibility into host data structures like files, databases, etc. and therefore does not provide any data cleansing capabilities.
    Data collection features: Performs deep discovery of the underlying SAN and storage environment to facilitate intelligent resource allocation when configuring network virtual volumes, copies or migration destinations. It understands the internal configuration of the arrays being virtualized (including the LUN to disk drive mapping) as well as the logical and physical SAN configuration. This information is used to select storage resources and SAN pathing when configuring the destination location of a volume migration.
    Management features: Users can actively move application data within a fabric without disruption to applications and respective hosts accessing the data that is being moved. Application data can be moved without halting I/O and with little to no performance degradation to the application. Network virtual volumes are created and presented to hosts for I/O, allowing storage to be provisioned to the host once and grown (increase size), transformed (change RAID Layout), migrated (change physical location), copied, replicated (to remote locations), and decommissioned without application disruption or the overhead of reconfiguring the SAN or the disruption caused by scheduled application outages.

    Veritas Volume Replicator software

    Storage system support: This option to Veritas Storage Foundation supports all major Unix, Linux, and Windows server configurations and a range of storage subsystems for FC and iSCSI SAN attached storage, as well as DAS.
    Application support: Ideal for replicating virtually any enterprise application or database between servers, storage systems or even between heterogeneous operating systems (for Unix and Linux). Commonly replicated applications include SAP, Oracle Applications, Oracle 10g, Sybase ASE, IBM DB2, Microsoft Exchange and Microsoft SQL Server.
    Migration features: Remote replication to heterogeneous storage; synchronous replication over Fibre Channel; synchronous replication over IP; asynchronous replication over IP; zero RPO replication; multiple initialization options.
    Data cleansing features: Continually tracks changes to preserve write order fidelity (ensuring data consistency) throughout replication activity. In the event of a disruption during replication, it uses the logs to rapidly restore data without compromising data consistency.
    Data collection features: Setting up replication essentially involves recreating identical logical volume structures on a remote storage device, setting up an IP link and initiating replication. This setup can all be done through a centralized secure web-based management console. Once it is set up, it captures all changes to replicated storage that occur during and after initial synchronization of local and remote storage.
    Management features: Centralized secure web-based management of remote data replication activities across multiple server platforms provides complete visibility to application, server, and storage resources. The web GUI provides step-by-step management and configuration to remove the complexity and error prone activities often associated with the set-up and ongoing management of enterprise software.
    Automation features: Includes controls for easily switching replication roles between local and remote sites. It is also tightly integrated with Veritas Cluster Server for automated fail-over of applications and data sets for a complete disaster recovery solution. With a single command or click, remote storage systems can assume the primary role in replication and applications resume operations at the remote site for minimal downtime during an outage. Automated resynchronization features help prevent downtime and headache associated with unexpected outages such as loss of IP connectivity.
