Introduced in April of 1998 as the replacement for the Enterprise 4000 server, the E4500 server is a fourteen-processor UltraSPARC-based system with eight board slots, has an 83/90/100 MHz gigaplane, and used 167 MHz, 250 MHz, 333 MHz, 400 MHz, and 464 MHz CPU modules. Maximum memory was 112 ea. 256 MB DIMMs, giving the system a maximum memory capacity of 28 GB. The E4500 also ha the ability to run internal disk boards which used 2.1 GB, 4.2 GB, 9.1 GB, and 18.2 GB disk drives, though they were intended primarily as boot disks.
The E4500 was EOL’d (end-of-lifed) in January 2003 and replaced by the Sun Fire 4800 server.
