Already, a few generic bridges have appeared. Okapi Software has the ipXtensionCord: a 10/100 model for $995, and a Gigabit Ethernet (GbE) version for $2,495. One place for the ipXtensionCord might be in front of a tape drive, making that tape resource available to any number of local or remote iSCSI servers. Over the Internet, Okapi has seen data transfer speeds of 9MB/s. "That's enough to spin an older model DLT drive at full capacity," says Bob Farkaly, Okapi's chief marketing officer.

Available in rackmount or standalone configurations, it supports both iSCSI and NDMP. Crossroads, too, has a first generation iSCSI-to-SCSI bridge due in the spring/summer timeframe, and says it will ship an... Access >>>
