Somehow I must have missed this try and buy offer before.
Evaluate the Sun Fire X4600 with PostgreSQL, MySQL or Microsoft SQL Server 2005. The Sun Fire X4600 M2 Server included in the program is available in two configurations. First configuration is 4 x Quad-Core with 16GB RAM and second configuration is with 8x Quad-Core (yes 32 cores in all) with 64GB RAM. Of course it only comes with two disks in it which means also need to "Try and Buy" the Sun StorageTek 2540 Array or the Sun Storage 7110 Unified Storage System with it.
Would love to see some real life deployment saturate 32-core Opteron system using only PostgreSQL or MySQL as the database system in it.
