Copyright (c) 1999 Mirotest

Q What is DiscZerver Technology?

A DiscZerver Technology is thin-server technology that provides universal accessibility, browser-based management, plug and play installation, fully automatic CD/DVD-ROM imaging and caching, local and remote image creation, CD-R support and an optional application launcher, statistics and metering utility.

Q How does DiscZerver Technology work?

A DiscZerver Technology is a combination of software and hardware that allows users to share and cache CD/DVD-ROM titles and create custom CDs, eliminates the need to connect the drives directly to the fileserver or locally to each network workstation, and improves access and multi-user performance.

Q How is DiscZerver Technology different from DiscPort Technology?

A DiscZerver Technology combines hardware and software to offer server independence, 10/100 Ethernet compatibility, platform independence, caching to attached-hard drives, remote load functionality, multi-tasking image and access, browser-based management, and CD-R and Mac support.

Q Does DiscPort Technology have advantages over DiscZerver Technology?

A DiscPort Technology offers advantages not currently provided by DiscZerver Technology: periodic update functionality, configurable volume sets, "hot swap" for devices, token ring support, support for 14 SCSI devices and better global management software (DiscView).

Q What is the advantage of caching CD/DVD-ROMs to a hard drive?

A Cost effective information sharing and improved performance are the greatest advantages of caching. It is far less expensive to purchase hard drives for caching and sharing data than to purchase and maintain multiple CD drives and multiple copies of CDs. Also, caching dramatically increases multiple-user access speeds.

Q Which network access protocols does DiscZerver Technology support?

A DiscZerver Technology supports NT (SMB), NetWare (NCP), Unix (NFS), OS/2 (SMB), Web (HTTP) and Macintosh (AFP).

Q What is the difference between DiscZerver (internal), DiscZerver (external) and DiscZerverVT?

A All three products offer the same software and benefits previously mentioned. The greatest difference is in the physical form and hard drive attachment: DiscZerverVT has an internal hard drive and supports 7 SCSI devices. DiscZerver (external) supports 7 SCSI devices and requires the addition of an external hard drive for caching. DiscZerver (internal) supports 7 SCSI and 4 IDE devices and must be integrated into a tower cabinet for use.

Q Are DiscZerver units difficult to install?

A DiscZerverVT and DiscZerver (external) are very easy to install plug and play products. Simply attach the unit to your Ethernet network, connect the power supply to your unit and plug the power supply cord into a wall outlet. That's it. DiscZerver (internal) requires simple tower integration - mount DiscZerver into a tower bay, connect SCSI and/or IDE devices to the appropriate DiscZerver connector, plug the power supply cable into DiscZerver's power supply socket, and attach to the network. It's that easy.

Q Will DiscZerver (internal) work with any standard IDE or SCSI drive bay tower available in the market or does the user need to buy Microtest Towers only?

A DiscZerver (internal) will work with any standard tower cabinet on the market today and will allow users to connect up to 7 SCSI devices and up to 4 IDE devices.

Q Will I have to bring down my fileserver to install DiscZerver?

A DiscZerver products require no network downtime or additional client software. Installation is easy and won't disrupt network users.

Q How is DiscZerver configured?

A DiscZerver Technology products are easily configured via browser-based management, the set-up wizard and user-friendly administrative utilities.

Q Do I have to put my DiscZerver products in the server room, close to the server?

A No, DiscZerverVT, DiscZerver (external) and towers empowered by DiscZerver (internal) can be placed anywhere on your network depending on your security, access and control needs.

Q Will DiscZerver Technology management run other Microtest products?

A LaunchPro, the free management, statistics and metering, and application launcher option, allows users to manage Microtest products as well as other vendors' products. The browser-based management that comes standard with DiscZerver products supports only DiscZerver products.

Q Is EazyImage the only way to load CD/DVDs to a DiscZerver?

A No, it is possible to cache images automatically or by manual load to a hard drive from local CD/DVD-ROM drives. EazyImage is the Remote Load Utility and was designed to increase product flexibility by allowing users to load images from remote workstations.

Q Do I have to type in my user IDs and groups?

A No, DiscZerver Technology takes advantage of Novell's NDS and NetWare Bindery as well as NT domain services, simplifying user access authentication and providing security access to each CD/DVD-ROM volume - physical or imaged.

Q What devices will DiscZerver support?

A DiscZerverVT, DiscZerver (external) and DiscZerver (internal) provide an external 50 pin, high density SCSI-2 connector that supports any SCSI-2 compliant device including CD/DVD drives and changers, hard drives and certain CD-R devices. Please check the Microtest web site for the latest compatibility list.

Q Does DiscZerver (internal) support both IDE and SCSI drives simultaneously?

A Yes, DiscZerver (internal) allows integrators to attach IDE devices and SCSI drives simultaneously.

Q Does DiscZerver Technology support jukeboxes, JAZ and/or Zip drives?

A DiscZerver products do not currently support jukeboxes, JAZ or Zip drives.

Q What CD/DVD-ROM formats does DiscZerver support?

A DiscZerver products support ISO 9660, High Sierra, RockRidge, Joliet, HFS, Hybrid, and Multi-session formats.

Q Does DiscZerver support CD-RW?

A Not currently. There are a few CD-RW devices on the supported CD-R list, however they are only supported in CD-R mode; CD-RW is not supported.

Q Does DiscZerver Technology support periodic updates?

A No, not in the current release. Periodic update/subscription functionality is scheduled for a future release.

Q Can DiscZerver products be used in token ring environments?

A No, DiscZervers cannot be used in token ring environments. Users needing a token ring solution should consider Microtest's DiscPort for Token Ring.

Q What client configuration is necessary to run these products?

A For administrators and remote load, the recommended configuration to run DiscZerver Technology is Windows 95 or higher, at least 16MB RAM and a browser such as Microsoft Internet Explorer or Netscape Navigator. For added convenience, Microtest includes a copy Microsoft Internet Explorer on the DiscZerver Technology companion CD that accompanies every DiscZerver product.

Q Do the units support hot swappable drives?

A Currently, DiscZerver products do not support hot swappable drives.

Q What does 66x speed do for me?

A The 66X emulation rate is a theoretical limit of DiscZerver Technology's capability. It is derived from hard drive transfer rates, not throughput.

Q How many concurrent users can be on a DiscZerver?

A All DiscZervers support up to 255 concurrent users.

Q Is there a limitation to the number of DiscZerver thin servers that can be attached to the network?

A The number of devices supported is determined by the network's capability.

Q How many database records will DiscZerver Technology support?

A Up to 511 volume database records can exist on any DiscZerver product.

Q Is there a limitation of the speed of the CD-ROM drives that can be used?

A No, DiscZerver Technology does not limit the speed of the CD-ROM drives that can be used. In fact, the faster the CD-ROM drive used, the faster the caching time (Ex: a 32X drive will process data much faster than a 4X drive.).

Q Do the CD-ROM drives need to be attached to the Microtest servers directly or can the servers work with the CD-ROM's being attached to various nodes on the network?

A It depends. To read physical CDs in a CD drive or changer, a CD-ROM drive or changer must be attached directly to the thin server. To cache CD images, users may attach a CD-ROM device directly to the unit (local caching) or may choose to cache remotely via the EazyImage utilities. For remote caching, the EazyImage software must be loaded onto the client(s) hosting the CD-ROM device(s). Installation of EazyImage is very simple and will automate the remote loading process.

Q How many defined/registered users can be on a DiscZerver?

A It varies by users and groups. Defined users - Up to 250 unique users can be created on the unit. Defined groups - Up to 32 unique groups can be created on the unit.

Q How many CD's will DiscZerver products support?

A DiscZervers can mount or share up to 248 CD-ROM discs or images at one time.

Q Will DiscZerver Technology support imaging of DVD titles?

A Images of DVD-ROMs up to 2 Gigabytes can be created internally on a DiscZerverVT or on hard drives attached to a DiscZerver (internal or external).

Q Does DiscZerver Technology support Mac users?

A With DiscZerver Technology V2.0 and V3.0, support is provided for the AFP protocol and HFS formatted discs.
