PMC-Sierra Inc. has introduced its 4G Fiber Channel (4GFC) cut-through-switch (CTS) product family that consists of the PM8379 CTS 20x4G, PM8378 CTS 18x4G, and the PM8375 CTS 4x4G devices.

According to PMC-Sierra, the CTS products enable storage OEMs to deliver low-cost 4G Fiber Channel disk enclosures with higher system performance, reliability, availability and serviceability than existing deployed systems.

The devices integrate the company's high-speed signal integrity, together with an innovative FC switch architecture, to provide one of the best-in-class solution for RAID, SBOD, MBOD, and JBOD enterprise storage equipment.

The CTS loop switch products are PMC-Sierra's third-generation of products for Fiber Channel storage enclosures. The CTS 18x4G and CTS 4x4G are pin- and software-compatible with the company's previous generations of 1, 2, and 4G intelligent Port Bypass Controllers (PBCs), allowing storage OEMs to provide increased disk error isolation and reduced loop latency capabilities while preserving existing hardware and software investments.

The products are interoperable with 4GFC hard disk drives (HDDs) over long backplanes and are compatible with existing 1G and 2GFC HDDs and storage networks. Providing OEMs with a low risk and optimized price-performance solution, the CTS 20x4G, CTS 18x4G, and CTS 4x4G feature embedded point-to-point CTS for hard disk drive isolation and loop latency optimization; per port monitoring and diagnostics for higher system reliability, availability and serviceability (RAS); robust signal integrity to lower time-to-market risk and increase system performance; programmable edge rate control to reduce system EMI; low receiver sensitivity; integrated ac coupling capacitors; and 100-ohm terminations to reduce system design complexity and BoM costs.

Targeting 4GFC storage system enclosures in Storage Area Networking (SAN) applications, the PM8379, PM8378 and PM8375 are priced at $70, $66 and $19. Product evaluation kits for each device (PM2349-KIT for CTS 20x4G, PM2348-KIT for CTS 18x4G, and PM2347-KIT for CTS 4x4G) will be available in May 2004.
