Good afternoon all. This is a quasi-on and off topic post, and I hope 
someone can help me out.

Here's my setup: Tyan (Tahoe?) MB with dual PPro 200 (on riser cards) and 
256 meg RAM, 4 gig and 8 gig IDE HD, DPT PM3754U2 SmartRaid V I2O Ultra2 
SCSI controller with 64 meg Cache, 4 9.1 gig Ultra2 drives as a single 
26.5 gig RAID 5 array. 

I'm currently running SuSE 5.3 with kernel 2.0.36. I have yet to upgrade 
to the 2.2.x kernels since I keep hearing about the file system 
corruption problems and other issues, and because the 2.0.36 system is 
working fine (sans an intermittant and recurring message about eth0: too 
much work at interupt...) so I am hesitant to mess with it.

Now I'm needing to add more hard drive space to this system. My thinking 
is to add an external SCSI rack or two. But then again, I'm looking at 
the options my DPT card gives me.

I'd like to add either the dual Ultra2 bus expansion module or the fiber 
channel module (the fiber says it will work with any SmartRaid V 
controller). In addition, I want to add a rack with hot-swap capability.

Now comes my questions. Are there any issues with SMP kernels and 
hot-swap hard drive arrays? What about the fiber option, does anyone have 
something like this running on their Linux systems? Would the dual Ultra2 
bus expansion be a better bet?

Thanks,
Greg
