Synchronous replication between remote EMC Symmetrix arrays isn't cheap. So when Cleveland-based Ohio Savings Bank built its disaster recovery site, it eyed telecommunications as a place to cut costs. "The big problem with synchronous replication is that you need a really fat pipe," says Donald Janosik, senior network engineer at OSB. Instead, OSB went for a dedicated Gigabit Ethernet connection, with redundant CNT UltraNet Edge FCIP routers. This cost OSB about 9% more than a 44Mb DS3 link, but provided 22 times the bandwidth, Janosik says. DS3 does have its advantages, says Karl Evert, partner marketing manager at CNT. Because SONET is a ring, data traffic can be rerouted if a link goes down. With Ethernet, "if a backhoe goes through your line, you're out of luck." To guard against that, OSB installed Cisco's wireless WT2710 point-to-point broadband system. The beauty of wireless? Besides the equipment, there are no monthly communications charges.
