Half a Terabyte in a X4600M2

When i started to work at Sun in 2001, Sun introduced the SunFire 15000. A beast with with up to 574 Gigabytes of RAM. A system with a size of a deep 19” rack. We were able to address this vast amount of memory in a single operating system image.Today DataRam announced a 3rd party (read: unrecommended, unqualified and unsupported by Sun) RAM kit for the X4600 M2 with 8 GB per module. This leads to 512 Gigabyte in a single system with four rack units. That´s technological progress.
