Indy(tm) Network and SCSI Option Cards

Ports for All Purposes

Indy(tm) workstations from Silicon Graphics(r) provide you with a multitude of standard interfaces, including audio, video, Ethernet(tm), SCSI-2, ISDN, serial, and parallel ports. But if you need additional expansion for bandwidth-consuming graphics and multimedia applications, the Indy workstation has two fully integrated, high-bandwidth, high-performance GIO expansion slots. A wide variety of expansion cards that enhance the video, networking, and input/output capabilities of the Indy system are available directly from Silicon Graphics.

High-Speed Networking with FDDI

The high-bandwidth system architecture of the Indy workstation thrives on compute-intensive applications and large data sets, which often demand more bandwidth than Ethernet delivers. Silicon Graphics has developed the industry's highest-performing FDDI solution, the GIO-FDDI expansion card. This card, which is capable of full bandwidth performance, gives the Indy workstation ten times the network throughput available from traditional Ethernet.

Dual SCSI Channels for Optimum Performance

Powerful applications need to access large amounts of data very quickly. To augment the internal SCSI channel, add up to two more SCSI-2 channels on the GIO expansion slots. Combining multiple SCSI-2 controllers with the disk striping available in the IRIX(tm) operating system significantly increases the available I/O throughput by providing an extra 10MB/second channel on each controller. A second SCSI-2 controller also provides extra high-performance connectivity for external SCSI peripherals such as disk storage, backup devices, scanners, and printers.

More Ethernet Means More Performance

Indy workstations are equipped with a native Ethernet port configured to instantly connect to IP networks. Let the Indy workstation route between the subnetworks or run separate networks on each port. Run IP, DECnet(tm), IPX(tm), SNA(tm), OSI, or AppleTalk(r) protocols using upper layer protocol stacks from Silicon Graphics or partners. In any case, the E++ card triples the possibilities for configuring your Indy workstation.

Token Passers Stop Here

Indy workstations let you opt for token ring networks instead of Ethernet. The GIO Token Ring adapter delivers high-performance connectivity to IP and SNA running on shielded or unshielded twisted-pair token ring networks. Indy workstations act as end-nodes on an existing token ring network or as routers between token ring and Ethernet networks.

The World is Waiting to Talk

With the GIOSync Synchronous Serial adapter card for Indy, Silicon Graphics gives you yet another way to connect to the worldwide network. For mainframe connections or links to wide area X.25 networks, the GIOSync adapter supports SDLC and HDLC on either of two independent 64Kb/sec ports.

Silicon Graphics also supplies the correct cable to connect to an RS-232, V.35, or X.21 CSU/DSU. You can even run SDLC on one port to your mainframe host while running HDLC on the other to connect to a worldwide X.25 network. Whether Indy is an SNA gateway, an X.25 router, or an end station in a wide area network, the GIOSync card allows for complete flexibility in wide area networking.
