Abstract

FORE Systems, Inc. commissioned The Tolly Group to evaluate its ForeRunner HE 622, a PCI adapter that transfers data at OC-12 rates (up to 622.08 Mbit/s). The Tolly Group tested the adapter on a Sun Microsystems Ultra 30 workstation and a Sun Ultra Enterprise 450 server (running Solaris 2.6) and Intel Corp. (formerly Digital Equipment Corp.) Alpha (NT 4.0) platforms. Testing probed the effect of extended packet size on both server throughput and the adapter’s impact on CPU utilization. Additionally, The Tolly Group exercised the HE 622’s ATM traffic management capabilities, referred to by FORE as LAppQoS (Legacy Application Quality of Service). Testing was performed in March 1998.
