DiskMaker® for OpenVMS

    Overview: DiskMaker for OpenVMS:

    As storage devices are constantly growing in size and improving affordability, OpenVMS systems managers are looking for strategies that incorporate existing storage systems and associated shadow sets to be utilized using OpenVMS Volume Shadowing without replacing already deployed storage. DiskMaker Delivers!

    The DiskMaker for OpenVMS utility allows OpenVMS System Manager's and System Programmer's to enhance the usefulness of HP's OpenVMS Volume Shadowing and/or Disk Striping products. WATCH(TM) Terminal Monitoring Program is a software tool that allows a user on one terminal to monitor and/or modify (advise) another terminal session interactively.

    OpenVMS Volume Shadowing Enhancements:

    OpenVMS Disk Management Volume Shadowing
    Figure 1: The VIRTUOSO Components Flow Diagram HP's OpenVMS Volume Shadowing product requires that all members of a shadow set have the same size in order to shadow the volume. With the different drive models in use today as well as the very large capacity, this requirement can represent a very big problem. With DiskMaker, you can create pseudo-disk volumes of any size, which are then shadowed by OpenVMS Volume Shadowing. This unique feature allows HP's shadowing services to operate between any type of drives regardless of make or model. For example, without DiskMaker if you want to shadow a drive you must purchase another with of identical size. With DiskMaker, you could shadow a "smaller" drive to a portion of another disk, and still access the unused portion for other applications. This feature is known as Heterogeneous Shadowing, and provides you with the ability to shadow different types of drives as long as enough raw capacity is available to meet your shadowing requirements.

    DiskMaker also allows you to create pseudo disks into which you can locate critical file(s) that you need to shadow. This feature allows you to focus your shadowing requirements and reduce the amount of density that would otherwise be required if you were forced to shadow an entire volume. For example, today you might have to shadow two (2) SCSI 36Gb disks to protect a critical 50mb file. With DiskMaker, you would create two (2) approx. 50mb pseudo-disks on your two SCSI drives and simply shadow the critical and smaller portion.

    Prerequisite Software:

    DiskMaker for OpenVMS V1.5 runs on any VAX or Alpha processor, using OpenVMS for VAX, Version 5.5-2 or later and OpenVMS for Alpha, Version 7.1 or later. HP OpenVMS Volume Shadowing is required for DiskMaker.

    If you don't have the HP product mentioned above, then ASCI's SHADOW family of products may be a more suitable fit for your needs.

    Optional Software:

    DiskMaker with Striping for OpenVMS can be purchased to provide striping facilities for those customers who own HP's OpenVMS Volume Shadowing product but don't have a Disk Striping package. This optional license allows users to create stripesets consisting of files and/or volumes.

    RemoteSHADOW is a separately priced product which allows you to shadow your data, with or without the use of HP's OpenVMS Volume Shadowing product, to other node(s) in your network. RemoteSHADOW is used to expand the media reliability strategy that local mirroring offers to also include a local site failure. RemoteSHADOW provides the ability to mirror your data, in real-time, to a hot site for the purpose of providing a quick and effective intra-day business recovery.

    VIRTUOSO(TM) Virtual Disk and Disk Caching system can be combined with DiskMaker to allow Data Caching, Encryption and other features that improve the performance, reliability, and security of data.
