Thanks everyone for your help. After going through all the material I have decided to do this. The cluster will have 7 nodes with this config: #1. AMD Athalon >=1.6 GHz #2. ASUS motherboard with onboard video RAM (8 MB) #3. Floppy drive #4. Gigabit ethernet #5. 20 GB ULTRA ATA HD #6. 1GB DDR RAM It will have one server (head) with these: #1. AMD Athalon >= 1.6 GHz #2. ASUS Motherboard #3. 32 AGP card #4. 1 GB DDR RAM #5. >= 80 GB SCSI hard drive #6. Floppy drive #7. Internal ZIP drive #8. CDRW drive #9. Two Gigabit NICs one for cluster, one for the external ethernet. I will go for 8 port full duplex Gigabit ethernet switch. I'll leave out KVM for the moment. The cluster will run Sun grid engine with Redhat 8/9. Do you guys think this is good enough. Or anyone has any suggestion? Malay curiouser@ccmb.res.in
