Virtual optical library and transition from 3995, 3996, and 399F

  • Click to show description Image Catalog optical media library for archive

    New capabilities are available to provide virtual optical library support with the IBM i 7.1 image catalog, easing transitions from IBM 3995, IBM 3996 and Plasmon optical libraries. These capabilities are available through an IBM Lab Services Offering and PTFs beginning in i 7.1.

    The image catalog optical media library (virtual optical library) is an alternative to physical optical libraries that attach to the IBM i for use as an archive storage repository with existing applications. Because this offering is based on virtual optical media stored in IFS directories, it has no dependencies on optical library hardware or host system adapters that can no longer be purchased. It is compatible with the latest POWER systems hardware and IBM i operating system versions. It maintains current application interfaces, so it offers a migration path from existing optical library media and preserves optical library enabled application investments.

    Image Catalog support is extended in i 7.1 to support loading a catalog to a 632B-001 virtual optical device in library mode. This enhancement of Image Catalog function enables the virtual optical device to function as a virtual optical library, and all volumes in the library-mode catalog are visible and accessible through the /QOPT file-system with no application changes. New virtual optical media types WORM and ERASE are also supported to emulate the characteristics of corresponding physical optical library media and facilitate compliance with data retention requirements.

    High speed migration of existing optical library media to the virtual device is supported with Image Catalog functions. New media images can also be created for ongoing archive production usage. Image Catalogs can be moved off-line or saved using backup/recovery strategies or individual volume images can be duplicated to recordable DVD media.

DVD Device and Media support

  • Click to show descriptionDVD Notes

    We currently support 3 DVD-RAM and 2 DVD-ROM internal drive types. All of these drives support reading CD-ROM, CD-R, CD-RW, DVD-ROM (DVD5, DVD9, DVD10, and DVD18), 2.6GB/5.2GB, and 4.7GB/9.4GB DVD-RAM media. Double sided media require the media to be flipped in the drive to access the second side.

    All DVD-RAM drives support writing 4.7GB/9.4GB DVD-RAM media. Only 1 drive supports writing to the 2.6GB/5.2GB DVD-RAM media (must be in a cartridge). These drives are also available as external units (Bridge box or Multi-bay storage device enclosure).

    Bridge Boxes: IBM 7210 Model 025 DVD-RAM drive IBM 7210 Model 030 DVD-RAM drive Multi-bay storage device enclosure: IBM 7212 Model 102 IBM 7212 Model 103 House up to two drives and can be any combination of the feature codes below.

    Performance

    When writing DVD-RAM media, i5 OS has ranked data integrity as the highest priority. To ensure this, we disable the drive's "Write Cache" function and write with a verify pass. This implementation results in a fairly large performance cost. When evaluating drive write speeds such as 2X, 3X, 5X(future), or 8X(future), you will see incremental improvement but will not attain these rated performance numbers.

    System Saves

    Most systems have a small window of time for their system back-ups. In most instances, tape is a preferred solution over DVD-RAM due to the slower write performance discussed above. When writing to DVD-RAM and using system compression, you will average a 3:1 compression ratio. With this, a single 4.7GB DVD-RAM media can save about 13GB of data in an unattended save mode. This may be suitable for backing up smaller iSeries models.
