Re: iSeries as a file server was: How Secure is Windows, Really?

And Linux on i is even faster than x on i. Raw disk price does continue to be a factor this much is true. BUT if you consider true cost of ownership you still save money with an i. I see customers routinely struggle with disk space on other platforms. They end up replacing servers because the one they have won't take more disk units. More cost more downtime more risk. They also struggle with backups on all those separate servers. They struggle with SANs and such in attempts to get past disk limits on their servers. Just this weekend one of my customers with a non IBM SAN spend much of the weekend down and as of late last night even some i partitions were down because they had some disk in ASP(1) on the SAN. No SAN no ASP(1). Big problem.
But the i itself is a very good SAN. IXS, IXA, iSCSI, Linux AIX, i5/OS all sharing the same pool of disk. A pool easily expanded to (*some really big number) on the fly. We can even add new towers now without power down or IPL. Rock Solid Reliability. Hot maintenance by a company who actually has spare parts and local service folk. I for one like being able to trust my system with my data.
If Rochester could get disk prices down this argument would be mute as there wouldn't be any reason NOT to use your i for everything.

access and is much more expensive.
Joe: I agree that the iSeries is not a good file server. Disk price is one big factor. The other is NOT disk speed. It is the operating system. Using the same disk hardware, etc, but using an IXS card with Windows loaded on it made a significant difference in speed.
