The SD npar is 60 % cpu lodaded on average. ( rare peaks 99 % ), mostly Oracle DB's are there heavy memory usage though!<BR /><BR />The SD cpu is PA8700 ( 750 MHz, 4 CPU's )and the new planned server BL870C uses Intel Itanium ( 1.6 GHz cpu cores ), so in total in broad figures for SD 4 CPU = 3000 MHz or 3 Ghz, so if I use 1 Intel itanium cpu 9150N i.e 2 cores of 1.6 Ghz approx to 3 GHz. <BR /><BR />So am i safe in this calculation, if I go with one blade server. <BR /><BR />If someone has moved from RISC to Itanium , how's the CPU side performance as per your experience.

Possibly some of the SPEC or TPCC ratings may help?<BR />Also, are you doing lots of I/O?
