That's where HyperTransport comes in -- it offers two schedulers in the hope that two virtualized cores can put more stages to use. It only works on the horribly inefficient Netburst architctures -- you will _never_ see HyperTransport on the Pentium-M or Intel's newer processors. The concept of multi-threading on a single core lives and dies with NetBurst.
I think you meant HyperThreading.
The next evolution is multi-threading across multi-core.
Yes, these are the chums in use in the newer boxes I used to admin. I loved the 3ware + riser card fiasco though.
Well, when you're pushing 200+ traces at 66MHz, there tends to be EMF/EMI issues. 3Ware isn't the only one that has had issues with traces. Remember, 3Ware 7000/8000/9000S (not 9550SX) use 0 wait state, 64-bit ASIC+SRAM devices. Trace length and timing is everything, and heavily affected by EMF/EMI.
Again, I refer back to the i865 v. i875 issues. The traces of a PCB designed for the i875 -- such as the Asus P4C800 -- didn't necessarly work for the exact same chip in the i865, because it tested to lower tolerances.
Ok, thank you for your explanation. I guess that is why we had to get one particular rise from one particular manufacturer.
The problems I have are related to their hardware, not whether there are good drivers or not.
Actually, the firmware has always been the issue. The ASIC+SRAM design was always sound. They've done some stupid things, like the RAID-5 firmware update for the 6000 series (which was _never_ designed for RAID-5). But other than that, it's always been a
I am sorry Bryan but we seem to have some misunderstanding.
3ware is on Intel 7500 motherboards.
The VIA issue is something else entirely.
The poor latencies just won't let me use a Pinnacle DC10 board without crashing.
??? Let me guess, RAID-5 on a 9500S? ;->
This is on a KT400 VIA chipset. Nothing to do with 3ware. This is purely a dumb VIA chipset problem.
The Tyan "Tiger" series is _not_ a workstation/server platform, it's the _desktop_ platform. That's a very common misnomer. The "Thunder" is the workstation/server series. ;->
Tell that to the one who picked the board.
I cannot wait for a promise by a Nvidia rep about their future chipsets using SATA NCP technology that will allow an open source driver to be written to be acted on.
Do you mean NCQ?
Yes :)
Understand that nVidia is _totally_open_ with their designs right now, including the SATA. But the SATA hardware just doesn't do NCQ at all.
Nforce4 Ultra and above support command queueing according to them.
But yes, nVidia has been extremely open.
Yes...where possible. Their SATA/NCQ implementation apparently does not allow them to provide specs or something.
