Achieving Gigabit Ethernet Benefits in i5/OS
Date Posted: January 01, 2008 04:51 PM

Dear Doctor, We recently upgraded our entire backbone infrastructure to Gigabit Ethernet. As part of the upgrade, we also added Gigabit Ethernet NICs to our Windows servers (our System i already had Gigabit NICs). As expected, network performance on the Windows servers improved dramatically; for example, our nightly backups complete in one-fifth of the time it used to take! Alas, our System i is seeing no speed improvements at all, even in large file transfers to the Gigabit-enabled Windows servers. We ran an SNMP monitor and are seeing no packet errors on the servers, System i, or intervening switches. What could be wrong?
