I've been experimenting with boot from SAN solutions using HP, IBM, RedHat, Ubuntu, and SuSE over the last year and a half and must say that so far I am happiest with SuSE 11 on HP hardware. I also prefer SuSE for the virtualized guests these days. My ideal: Nehalem proc on HP box - (maybe even Cisco UCS soon) SuSE 11 Enterprise Multipath with QLogic HBA's I tend to avoid IBM x Series for boot from SAN because of the myriad problems encountered when trying to get it to boot on the DR side of the equation (LUN replicated with RecoverPoint was target) Ubuntu worked nicely for the boot from SAN with a little customization and tweaking but SuSE just works out of the box without any manual intervention or special multipath configuration. I'm really curious to see how the new IBM eX5 works in the real world too. |
