Adapter supports SCSI/IP/VI over FC

Dave Simpson

This month, startup Troika Networks Inc. will begin shipping a host bus adapter that supports as many as three protocols on one PCI-to-Fibre Channel board: FCP-SCSI, FC-IP, and FC-VI. In a multiprotocol implementation, SCSI would be used to connect hosts to storage devices, while IP handles networking or in-band management and the VI (Virtual Interface) protocol is used for server clustering and remote mirroring. All of the protocols run over Fibre Channel.

Called SAN2 ("SAN squared") Controller 2000, the adapter is designed to marry clustering technology with storage network technology, combining storage area networks (SANs) and system area networks, or clusters. As such, the controller will compete in part with proprietary clustering schemes from vendors such as IBM and Sun, as well as with PCI-to-Fibre Channel host bus adapters from ven- dors such as Emulex, Hewlett-Packard, Interphase, JNI, LSI Logic, and Qlogic.

Analysts say Troika`s adapter is the first to support all three protocols. "The availability of VI over Fibre Channel opens up the next phase of opportunities for application developers to exploit SANs," says Ed Frymoyer, president of emf Associates, a consulting and training firm in Half Moon Bay, CA. "The critical integration of VI, IP, and the SAN has now been realized."

On the software front, the adapter currently ships with a management agent that allows functions such as LUN-level zoning. However, Troika plans to roll out extended policy-based management tools--called SAN2 Sockets--in the first quarter of next year.

The adapter supports Windows NT, with Solaris to be added in the first quarter, followed by other Unix implementations and NetWare.

Headquartered in Westlake Village, CA, Troika was founded in early 1998, and is funded by venture capital. The company is targeting OEMs, systems integrators, VARs, and ISVs.

Pricing for the SAN2 2000 series controller starts at $2,939 for a version that supports all three protocols.
