LSI software management is complete shit compared to Areca's
Hey Odditory, quick q- in one of you screen shots you have the HDD Queue Depth set to 32. Whats the dif between 1 and 32? Is there a big performance impact?
As far i remember, any Areca product with "ix" in the name means its running off a port multiplier; so cramped bandwidth and compatibility issues. Please someone verify - i'm lazy today.
Question: am I better off going with the 8 drive 1680 with the HP SAS expander or just getting the 24 drive capable 1680 and skipping the SAS expander?
"Available now" means give it a month before you can buy one.
Any word on what the Areca 1880 cards will be selling for? Will they be replacing the current MSRP of the 1680 cards or living along side them with a higher MSRP? I hope they plan to be matching the prices of the LSI cards since the new Areca 1880 has slightly lower hardware specs using only 533Mhz DDR2 VS 800Mhz DDR2 compared to the LSI cards. I guess it all depends on how well the new Marvell 800Mhz ROC on the Areca 1880 matches up to the LSI 800Mhz ROC, as well as firmware/driver optimizations. Marvell's less than stellar SATA 6Gbps controllers up to this point, doesn't exactly build up my confidence that they'll pull off an amazing SAS 6Gbps ROC/controller combo chip, but who knows. Still, the larger Areca cards have >8 ports and allow up to 4GB of cache, so they'll keep that advantage.
If they do co-exist, I hope the 1680 cards get a price drop and they don't charge a $500 premium over the current prices just to get SAS2.Pricing hasn't been announced yet. I'd assume they different gen cards will coexist- why not? The 1280ML still sells for over $1000 after all these years.
Comparing Marvell 6Gbps SATA controllers in the same sentence with the SAS ROC on the Areca 1880 = apples versus oranges.
Why do you say it's apples to oranges when the Marvell 88RC9580 ROC on the 1880 has an integrated SAS/SATA 6Gbps controller built-in?Cebit 2010 news said:Test Copies of the ARC-1880, already last year at the Cebit show with the promise that the cards in the first quarter of 2010 would come on the market. The new adapters are no longer based on I / O processors from Intel, but running on a Marvell 88RC9580 processor. This chip is clocked at 800MHz and features an integrated controller sas-6G. The cards have a PCI Express 2.0 interface with eight lanes and are standard equipped with 512MB DDR2-533 memory.
Very true. I also didn't realize the Marvell chips were ARM based (for some reason I was thinking they were PowerPC based, my mistake) or that they bought Intel's ARM division. I wonder if the ARM portion will end up being based on that quad-core they showed at CES. If so, it really may end up killing the competition.Remember Intel sold their ARM division off to Marvell, so the ROC on the 1880 is the first major byproduct of that transition happening in this category. Also 1880 having slower cache mem or CPU clock than the LSI card tells us nothing - it's all in the implementation and optimization. As we saw with Adaptec 5 series versus Areca 1680, the two gens of cards used the same IOP348 and similar memory yet the 1680 blew the doors off the Adaptec with I/O throughput, build speed, OCE speed, repair speed, etc by 2 to 1, in some of my tests 3 to 1. Even the previous gen Areca 1280ML was faster than the Adaptec 5 series in most tests.
Are there any issues with prioritizing which RAID card the OS will boot off of? Not sure if this depends on mobo or not but this would probably be going on a DFI P35 board.
