Linux When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux. As late as 2007, Wall Street exchanges were still largely run on Unix . . . Over the past few years however, Linux has crept into this market, showing up first in ancillary systems and then running a few core exchanges.

RE[4]: Linux is killing

I don't know about system z, I'm no sys-prog, but I do know about LoP (Linux on POWER) and compared to AIX, it's a joke. No support for software RAID boot partitions, buggy SAN mulipath drivers and every time I've seen an installation, it's needed to be heavily optimized due to it having lower (and sometimes much lower) I/O performance than AIX. Bad I/O on a POWER system is an oxymoron.

Sure, LoP is OK I guess as a test LPAR but as you've got all the open source server software you need already compiled for AIX, why the hell would you want to add an extra support contract for what is arguably a less powerful OS for your expensive POWER system when you get AIX support added in already?

As for system Z, my sys-prog mates think it's great cause they can implement open source server software without the humongous license fees but again, that's not because zLinux is somehow better than zOS.
