I have a K450 server with 4 160MHz CPUs and 1GB memory.I want the processor ratings , so that I can purchase for servers with matching processing powers.
Thanks & Regards
Vinu

Re: K Class Server CPU ratings
K450 with 4x160 MHz CPU ~ rp2470 with 1x650 MHz CPU or rp5430 with the same CPU.
You can find some comparision here:

Re: K Class Server CPU ratings
The memory bus was 960MB/sec. HP-PB I/O slots were <32MB/sec and HSC slots were <160MB/sec, and they were shared bandwidth except for the HSC slot on the core I/O which was <120MB sec. Those numbers were peak (downhill with the wind behind your back). Today, if you can use HP-UX 11i, you can get pa-8800 based systems, like the rp 3440-4 with up to four 1GHz processors (1.5MB per core on chip cache and with a 32MB of chip cache shared over two processor cores), a 6.4GB/sec bus from the processor and up to 4GB/sec of I/O bandwidth with PCI-X cards. One processor core is more than a match for the K450 with four CPUs. Still, you want to get more RAM, as 1GB is very light for a 4 CPU configuration even on your K450. With today's fast chips, usually 2 GB per CPU is a good starting point, and 2 GB of RAM is the recommended minimum memory for HP-UX. Also, make sure that you don't drop your number of physical disks to lower than what you had on the K, unless you know the number of I/O's per second that you need and have calculated what you will get from a new disk solution.

SolutionHere is a document I put together, gleaned mainly from www.tpc.org and www.spec.org, which lists a variety of HP boxes, with relative performance figures (some interpolated, some based on other, similar boxes). It ain't perfect, but it is a decent enough general guide to relative server performance. Use at own risc (pun intended).
Hope it helps!! --bmr
