many small design house use linux EDA ..
as I know
(a) CPU & RAM
1. use K8 is fast than P4
2. if you want many people share 1 server
like > 2 people use hspice in X86 ,
Opteron is good CPU than Xeon --> tech report
but opteron need use ECCDRAM --> very expensive
1G ECCDRAM -> U$400 , but DDR1 1G only $200 ..
3. at least 1G DRAM for simulation .. and use good 2D graphic for display
large simulation waveform (if you over ethernet you need 100M bits ethernet)
don't need 3D VGA
for P&R , I think you need much more memory
(b) HD
1. SCSI is fast .. but some Motherboard & linux need setup SCSI card IRQ
2. you need Raid system for backup .. but I find some IDE raid only
have windows driver
3. don't use Serial-ATA .. linux lack of driver , becuase EDA usually old version linux
(3) OS
redhat 7.2 is better , or redhat8 ..
other linux FC or susie .. you will meet some problem for setup cadence tool
finally .... don't setup illeage linux EDA and saving money for your company ..
because your boss don't give you much more money ,
but if your company use illeage tools , and be find by Cadence ..
your boss will said "this is personal and do by engineer, not company"
another problem is , MIS don't deal with this EDA server .. you must handle it
but you "never nevry..." get much more money from your company
