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