| Last purchase | May 2002 | September 2002 (434 systems) | August 2002 | August 2002 (20 systems) | September 2002 (160 systems) | Near future (20 systems) | November 2002 (~ 250 systems) | October 2002 (3 systems) |
| Processor | 2 x Intel Xeon 1.4 Ghz | 2 x AMD Athlon MP 2000 | 2 x AMD Athlon MP | 2 x Intel Xeon | 2 x Intel PIII 1.4 Ghz | 2 x Intel Xeon 2.4 Ghz | 2 x Intel Xeon >= 2.2 Ghz | 2 x Intel Xeon 2.2 Ghz |
| Mainboard or system | SuperMicro P4PDR-iGM | Tyan 2466 (Tiger MPX) | Tyan 2462 (Thunder K7) | i E7500 chipset | IBM xSeries 330 | SuperMicro P4DPR-I | unknown | Dell PE2650 |

| Chassis | 19" 1U (SuperMicro SC812i-400) | 19" 2U | 19" 1U | ATX minitowers | 19" 1U | 19" 1U | unknown (presumably minitowers) | 19" 2U |
| Fully specified | Yes (for chassis, only form factor) | No (qualified hardware defined, vendor chooses within these constraints) |
No (asked 1U, dual, onboard VGA and Enet) | Yes | No, some constraints only | Yes | No (constraints only) | |
| Future | 25 systems next year same specs with faster processors |
Almost continual purchases will specify more details for power supplies and racks |
Next purchase in 1 years' time no details yet |
Purchases almost monthly Xeon specs not settled yet Looking at turnkey solutions (eg. SuperMicro Superservers) |
Next purchase in 2...4 months expect specs to evolve until then |
Expect another purchase during 2003 Specs expected to evolve |
End winter 2002/03: interested in blade servers | |
| Comments | Using Hyperthreading: 4...5 jobs per node (was 3 on dual PIII) | Moving to 1U | Should have got Tyan Thunder K7X | Until recently: 2 x Intel PIII 1.266 Ghz, SuperMicro P3TDLE, ECC SDRAM 133 | Athlons better for floating point applications | Using dual PIII and dual Athlon systems, too | Expecting blade server prices less than 1U for one drawer | |
| Comments | Vendors provide racks, wiring, installation | Original mail | Sceptical towards Athlons | P4 Xeon performance much application-dependent | Original mail (very detailed) | Original mail | ||
| Original mail | Original mail | Would favour 19" 1U or 2U | Original mail | |||||
| Specification used last time | Original mail (lot more details) |
