Hurricane IKE notice

As you may know Advanced Storage Concepts is on Galveston Island which took a direct hit from Hurricane IKE on Friday, 12 Sep 2008.  Access to our office is currently impossible and severely impacts our operations.  We will keep this section up to date as events unfolds.  You may contact us via email at wjc@virtualscsi.com.

Thank you.

 

VirDIS (Virtual Disk Image Server)

for Digital Audio Recorders, etc.

Testimonials

"Can't tell you how awesome it was to export my .wav files to an ISO {file} and burn it with the 48x on the PC. A real time-saver!"

- Nick Morabito, Los Angeles, CA

"VirDIS totally rocks.  A must-have tool if you're a serious 2480 user.  It nicely bridges the gap between the 2480 and PC.  Track Exports/WAV Imports no longer require wasting expensive CD-Rs and the task is handled more quickly.  With VirDIS I can easily copy 2480 project data to/from my PC hard disk.  On the PC project data can be written to DVD for permanent storage.  VirDIS streamlines my operation and is a great time saver to boot."

- Frank Cupal, F&S Productions, Houston, TX

"VirDIS would have to be one of the most innovative third party interfaces developed for the Roland VS-2480HD on the retail market today.  ....  As a VirDIS user, I can say that VirDIS is something I now use with confidence, and rely upon daily for every recording made on the Roland VS-2480 including cross-platform projects. .... I recommend this product to all VS-2480HD users wanting an efficient method of storage to PC HDD (including DVD-R backup) and VS-2480 Track (.WAV) transfer."

- Paul Webber, Winyard Productions, Melbourne, Australia

What it is

Leveraged upon the large code library of the VirtualSCSI line of emulation products Virtual Disk Image Server provides an easy to use means for the non-programmer to emulate on a PC certain SCSI storage device-types (like Hard Disk, CD-R, etc.) used by members of the audio recording engineer community and others.  VirDIS is really easy to use - it simply takes the place of a Hard Drive and/or a CD-R device.  Your PC supplies the 'virtual' media for both in the form of files (PC disk space).  You just plug in the VirDIS Target board, install the software, cable up to the audio recorder and go!

Block diagram of connections between Target machine running VirtualSCSI and various Initiators and between Target machine and the kinds of Target data objects that can be used by the VirtualSCSI application, e.g. Hard Disks (FC, IDE or SCSI), Target system RAM and now either locate or remote file images for Target data storage.

How it works

Using a simple graphical interface combined with a VirDIS SCSI Target Bus Adapter the user creates/selects a filename to use which will be a block-for-block representation of the selected SCSI device-type.  After setting a SCSI ID and setting (for new files) a desired device-size (limited only by Target PC storage) the user simply presses a button to load and start the device emulation.  Another button allows the 'ejection' of the disk-image file and load or mount another.

One key advantage of VirDIS is that these emulation files (disk-images) can be stored, re-used, compressed and sent via the web to customers, collaborators, etc.  Audio operations like Track Export/WAV Import, HD Backup, etc. can be performed directly on these disk-image files rather than using 'real' device.  And not only easier but much faster!

Burning through CD stacks to backup your hard drive is now a distant memory!!  Backups are now managed beautifully on your PC.

Device-types

Currently, there are two supported device-types with a third and possibly others anticipated in the near future.  The two emulated types are CD-R and Hard Disk.  The next device-type will be DVD-R with others possibly added later.  Users of audio recording equipment such as the Roland VS2480 may cable up to the PC on which VirDIS is hosted and select the devices and configuration that the equipment will detect on the SCSI bus.  The user selects the type of device to emulate by clicking on the appropriate control in the top-most window.

Background

VirDIS sits atop a tried and true set of SCSI Target Mode system modules that have close to 12 years of history behind them.  Since 1996, following a long history of SCSI Host Adapter development and production, Advanced Storage Concepts has specialized in the development of SCSI Target Mode tools for DOS and later for Windows.  VirtualSCSI has mainly been marketed as a advanced tool for system developers seeking to 'virtualize' SCSI hardware peripherals like disks, tapes, scanners, optical disks, etc.  Initially concentrating on the base functionality by building a library of SCSI Target function calls which in turn communicate with one of the most complex kernel-mode drivers in the world, ASC subsequently developed source code for a limited set of device-type emulations beginning with Hard Disk.

It is upon these software components and ASC's line of SCSI Target adapters that new graphical user interface of the VirDIS rests.  New methods of inter-module communication were developed in order to display 'live' or quasi real-time information that percolates up from (and down to) the SCSI Target adapter via the driver and library modules.

  •  Unrestricted (except by PC capacity) HD storage size
  •  Virtual i.e. physical-device-less implementation of SCSI storage devices at the push of a button.
  •  Flexible storage or transmission of emulation disk-image files over the web or via email.
  •  Disk-image files (particularly the ISO files) can be later opened/edited with 3rd party tools.
