RE: Hardware Comparison between SUN E6900 and IBM P570

I have experience with the p570. it is extremely scalable and powerful machine. it is definitely not a tricycle. I have this machine installed on few different customer site (mostly are using LPAR) that seems to be satisfied with its performance. AIX as an operating system is my favorite. It is very robust and can be relayed on for mission critical systems. With new version of 5.2 and 5.3 you hardly need to reboot. Even increasing/reducing filesystem size, adding removing swap are all done online. most kernel/network/nfs/vmm parameters are tuned dynamically (for most of them). AIX 5.3 give the advantage over 5.2 of micro partitioning and SMT (simultaneous multi-thread) something similar to HT in Intel where you have 2 logical CPUs per physical processor. The performance improvement is measured around 30%.

For example at my last company we used a 64 way sun box E10000 at the time, to support a badly written application supporting 3000 users. The database was 400 Gigabytes. Performance was reasonable until someone did something stupid. (cross product 100 million row tables) The problem is that MIPS, or benchmarks mean so little. So if you are comparing IBM versus SUN one might quote you a tricycle and the other might quote you a Ferrari. Of course the tricycle will cost less but can it really beat a Ferrari? Since I haven't worked on a lot of different hardware I can't tell if the salesbots are blowing smoke when they say our 10 way is faster than their 16 way. It might be or they are just trying to make a sale knowing that once we go to all of the trouble of moving to the new platform they can sell us an upgrade because our application is "surprise" not performing as we and they thought it would. I know they would be so dissappointed to have underestimated to get the business and then have us turn around and have to buy more hardware. I am also not the biggest fan of IBM (I had to write JCL for about a year and I will never forgive them for this.) I am a fan of the power processor it looks really fast. How is AIX as an operating system? Can you run Informix on Linux on a power box or will the Linux version only run on x86 hardware? _______________________________________________ Informix-list mailing list Informix-list@iiug.org http://www.iiug.org/mailman/listinfo/informix-list
