It=B4= s=20 not THE killer for speed, but it=B4s fairly stable, factory-supported on=20 FBSD, has good management utils (including remote, via daemon) and is=20 about half the price of its competitors. Besides, the "A" model has its=20 own XOR processor, what apparently frees some CPU usage (I can=B4t really= =20 tell, since we use them on quite good machines and haven=B4t seen good=20 benchmarks comparing 1820 to 1820A). In addition, it=B4s low-profile, fitting even 1U rack servers, and=20 provides its own brackets for low- and high-profile... *but* it has no=20 integrated memory, and no I2C options, if it=B4s an issue. It=B4s the onl= y=20 downside with them, in my opinion. In the other hand, I would take a look at the Areca=B4s, it=B4s not the= =20 first time I hear good comments on these. They=B4re double the HPTs price= ,=20 but come with onboard ECC SDRAM and I2C features. Sounds good to me. ;) Good luck. :) T=FAlio G. da Silva Peter Losher wrote: >On Tuesday 18 October 2005 03:36 pm, Steven Hartland wrote: > =20 > >>Anyone got any SATA RAID 5 controllers they can recommend >>64Bit PCIX. >> =20 >> > >I personally would reccommend the HighPoint RocketRAID series (we use th= e=20 >1820A here on a dual Opteron system running 5.4/amd64) We are using th= e=20 >HP-provided hpa.ko amd64 kernel module, but thanks to HighPoint and Scot= t=20 >Long, -CURRENT, 6.0 and 5-STABLE now have the amd64 driver integrated=20 >into /usr/src tree .
