There are some major improvements on the WINTEL at 4.2.1. First of all, they do raw IO to the disk pools with 256K blocks. We observed some significant performance improvements that lead me to believe that up to 50 Windows Server clients could be supported by a 4 way WINTEL if you have fibre channel disk and tape like Shark and Magstar and there are enough buses in the WINTEL to spread out the IO. You will find that the high-end Wintel server to do this probably costs more than the UNIX server would that could do it with 2 processors and half the memory. So, you have to decide. With the right hardware WINTEL will run well. Actually, much better than some competitive products.

For example in many PC servers you cannot have both SCSI RAID adapter and FC adapter without performance penalty. Usually only high-end (4 proc and above) servers have more than one *primary* PCI bus. Others have only one primary and the rest are through PCI-PCI bridge. For those 250 GB/night Intel server ought to be enough but I am curious why to downgrade. Zlatko Krastev IT Consultant Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> Sent by: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc: Subject: Win 2K VS AIX Has anyone on this list performed any performance tests on Windows 2000K/Intel VS AIX/RS-6000's or have any general comments concerning the Windows 2000 VS AIX TSM configuration. We have around 2TB in storage and pass around 250GB a night to the server. We are planning on an upgrade and are currently using a RS/6000 H70 and have no complaints with this platform at all. One of our vendors is offering a Win 2K platform - I've always been a bit concerned using the Intel hardware configuration for this application ( Performance ). Any comments or suggestions would be appreciated Thanks Mike Walker St. Joseph. Celebrating 100 Years Of Healthcare You Can Have Faith In.
