                             NetWare costs $395

                             Windows NT costs $695                   

           NetWare costs $1895

           Windows NT costs $1395

            Other options include:

              Raid- $995                        Disaster Recovery for Windows NT- $395

              *Image- $995                     Data Migration Storage Server- $2995

  *Image Option not unavailable for NetWare version

The device is also available in Macintosh and Unix Ware for additional costs

 Two different versions:

1. Single server edition- Allows backup of one server, but multiple client PC’s

2. Enterprise edition- Allows backup of multiple servers and multiple client PC’s

Compatible with two servers:

Other Options Include:

Intelligent Disaster Recovery (IDR)-  It creates recovery disks for backup server, Windows NT and NetWare servers on the network, so if needed the servers can be booted from the IDR disks to recover the data.

Benefit: NetWare version of this product can be installed from a remote client PC.      

Difference: Replica copies files from the server to a tape device.

Two different versions:

There are three different kinds of storage.

Basic purpose: To switch the storage away from the servers, and to be shared among multiple users.

Focused more towards fiber technology, by allowing the data to transfer on fiber optic

Channels at a high speed and bandwidths, at a distance as far as 10 Kilometers.

    Three primary components required:

Interface- It allows storage to be away from the server on the fiber channels.

Interconnect- It is the mechanism that allows to exchange data between devices like

                     hubs, switchers, gateways.

Fabric- Is the basic platform that lays out the network topology.

A disk array that directly connects with LAN interface via Ethernet and functions as a

  server in a client/server relationship.

  A shared storage device that attaches multiple host servers through storage interface

 like SCSI, FC. SAN is a extended storage bus, which connects to LAN’S or WAN’S, routers.
