I need a high speed network connection between 2 database servers on IBM Netfinity servers. What are my options and what hardware do I need? I was looking to gigabit ethernet first, as I figured it would be the cheapest. But a sysadmin I know said he wasn't sure but he thought about $4,000 for two cards and a switch. Is it really that much for gigabit hardware? Is gigabit the cheapest alternative? What kind of switch is required? What's the difference between a switch and a hub? What's the actual transfer rate you can achieve? 1,000,000,000 bits per sec/ 8bits = 125,000,000 bytes per sec 125,000,000 bytes per sec / reality =~ 20MB/sec I'm guessing. If someone is familiar with this, could you send me some part numbers I can look-up? Thanks. Paul
