2. DESCRIPTION
2.1 General. Congratulations on your purchase of Paralan’s iS5xx series iSCSI
Bridge! Paralan’s family of iSCSI Bridges make it possible to merge parallel
SCSI storage into IP (iSCSI) Storage Area Networks (SANs). If you do not
have an IP SAN, Paralan’s iSCSI Bridges will easily and inexpensively locate
storage and backup SCSI devices anywhere for disaster recovery or remote
backup – yards, meters, kilometers, or miles – the distance is unlimited! Paralan
offers the iSCSI Bridge in three standard form factors to meet a variety of
configuration needs:
2.1.1 iS520: Stand-Alone Box version. Simply connect cables and
apply power.
2.1.2 iS521: Board version. Perfect for OEMs and System Integrators
to incorporate into their own packages.
2.1.3 iS550: Rack Mountable version. Conveniently mounts Paralan’s
iSCSI Bridges into storage racks.
3. FEATURES
3.1 Feature Overview.
3.1.1 Both targets and initiators may be located on the SCSI side of the Bridge.
3.1.2 Communicates with SCSI disk, tape drives and libraries, RAID
controllers, DVD, MO and CD jukeboxes.
3.1.3 Allows full SCSI cable lengths on the SCSI side of the Bridge.
3.1.4 SCSI LVD operation up to 160 MBYTES/SEC using 68 pin high-density
“P” connector and conforms to the full ANSI standard.
3.1.5 The iSCSI Bridge is backward compatible with all older versions LVD
and SE SCSI.
3.1.6 Mode switching of LVD or SE is done on the fly by monitoring the
DIFFSENS signal and automatically supports all Single-Ended SCSI
versions.
3.1.7 SCSI ID for iSCSI Bridge is configurable.
3.1.8 User can optionally supply power for terminators on the SCSI bus (up to 1
Amp).
3.1.9 Unit can force Single-Ended operation on SCSI bus.
3.1.10 User can optionally use on-board terminators.
3.1.11 Supports 1.0 Gb/s Ethernet link speed – Full duplex.
3.1.12 Ethernet interconnect operates up to 100 meters (328 feet) of 1000Base-T
Copper (CAT-5e or CAT-6) cabling using a single RJ45 connector.
Switches and routers may be used to extend the distances.
3.1.13 Configurable IP port for “system” management, upgrades and diagnostics.
Downloads achievable via on-board Web-based Utility using the most
common industry web browsers, e.g. Microsoft’s Internet Explorer.
