CacheFlow Inc is extending its web caching appliance line onwards and upwards with a new high-end configuration designed to support carrier-class companies with internet pipes ranging from T3 (45Mbps) to OC12 (622Mbps).
The 622C-Link can be used in Fast Ethernet, FDDI, high-speed token ring, ATM155 (OC3), ESCON, Fibre Channel and ATM 622 (OC12) environments providing links of up to 30km.
Other products in the series--OptiStar OC12 and FC1000R adapter cards, as well as Replicator and MediaServe server software--will be available soon.
In its most common implementation, ATM relies on OC3 links, and the only way to increase bandwidth to Gigabit Ethernet levels is to install more expensive multiple OC12 lines.
