We are looking to phase-out our 2-AIX TSM servers and replace them with Linux/Dell boxes (state contract - don't have a choice on the hardware). They have asked me to come up with some prefered specs

Windows is not in the picture. These are going to be RH Linux systems. We will probably perform EXPORT TO SERVER to move the clients, one by one, since we are probably going to move to new media type
Look for the type of system that will give you the most PCI-X bandwidth you can get. You are going to be pumping quite a bit of data across that bus, with presumably 4Gb HBA's, some SCSI (?), network
I/O bandwidth is the key. Since these new systems cannot match the I/O bandwidth of the AIX pSeries systems they are replacing, count on having to run MORE SERVERS to accomplish the same work. Having

Thanks for the suggestions. Unfortunately, we are highly unlikely to get 4GB HBAs, especially since nothing in our SAN fabric goes higher than 2GB GBICs. Bob Booth <booth AT UIUC DOT EDU> Sent by: "A

Thanks for the feedback. Yes, I realize you can't beat AIX for I/O bandwidth. Unfortunately, it comes down to $$$$$$ (doesn't it, always). I agree it would be beneficial to break things up. However,
I think your $/performance-unit is much better on AIX than it will be in intel-land. I call the x86 option cheap now, pricey later. But you've already said that AIX isn't on the table. I don't under

We never have enough resources. The 4-LTO drives in one library, are shared amongst 3-TSM servers which transfer over 2TB, nightly. The 4th TSM server is dedicated to Domino backups, which use it's 4
Zoltan, I did a consulting gig at a large TSM site a million years ago that sounds similar to yours. In their case, they had a TSM server that was flat out 24*7 and did not have enough time to do eve
Actually, it will work just fine. Any number of TSM server images on one computer can share a physical tape drive connection (or tape drive partition) with no additional contention problems, beyond t
