SBS Technologies, a leading provider of embedded computing technology, has introduced its new PMC-ISCSI-ST, a single-wide 32/64 bit, PCI/PCI-X Mezzanine Card (PMC) for enterprise level storage and networking systems.

Available from Metromatics , the PMC-ISCSI-ST is designed for applications requiring a high-performance low CPU utilisation SCSI peer-to-peer solution as well as NAS (Network-Attached Storage) and Ethernet networking applications.

The PMC-ISCSI-ST's QLogic ISP4010 iSCSi controller includes both the PCI/PCI-X host bus and the 1000BaseT Ethernet interface. This mezzanine card features two embedded 32-bit RISC processors for protocol stack processing support while TCP/IP and iSCSI offload capability is fully implemented in hardware.

This card can function as both an iSCSI and an Ethernet controller at the same time. For Ethernet connectivity either the TCP/IP offload (TOE) interface, requiring custom API available from SBS, or standard Ethernet interface can be used.

Use of the TCP/IP offload engine (TOE) dramatically reduces CPU utilisation. This dual-function versatility is aided by a front panel RJ45 connector and two front panel LED indicators for link and transmit activity.
