I have used LSI HBAs exclusively. Performance and reliability has been very good. The only problem I have consistently seen is if I hotplug a sas expander with or without disks attached it will crash the system at least half the time. I have simple resolved never doing that hot. I have stuck with LSI because of using LSI SAS expanders to keep the communication across venders to the minimum. The last thing I want is to be in the middle of finger pointing between venders. -Chip <div class="gmail_quote">On Thu, Jul 18, 2013 at 7:03 PM, Saso Kiselkov <<a href="mailto:skiselkov.ml@gmail.com" target="_blank">skiselkov.ml@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>On 18/07/2013 23:48, Tobias Oetiker wrote: > Folks, > > We are specing a new omnios server box ... and were just told by > our vendor, that LSI HBAs were much slower (50%) than Areca Controllers > running in JBOD mode ... and that they would therefore recommend > Areca (we use areca for raid6 in linux boxes, but have never used it in JBOD > mode with illumos, yet). > > Which controller would you choose for a new system ? </div>Hi Tobi, I'm using LSI exclusively, never had an issue with them. Their 6G SAS HBAs are very affordable and remarkably solid. As for the ARECA vs LSI debate, I'd contest that there's going to be any appreciable performance difference. *IF* you're running in JBOD, the card should essentially be a simple pipe for SCSI commands to the SAS bus with as little overhead possible. I know for a fact that saturating a 6G SAS link isn't a problem with LSI cards, so I'm somewhat at a loss as to where the performance difference is supposed to lie.
