SAS is getting closer!

So, sometime this year you will be able to plug yer SAS and SATA hard drives (along with SATA opticals and whatnot) into a high performance SAS controller.

I was thinking about something along the lines of Rice Krispies boxes with 50-pin connectors....

Free SAS host adapter inside the box!

3 GB/sec drives? Any idea about what kind cost for such a setup?

At what point is there a bottleneck on the current server/workstation Supermicro motherboards? In other words, what can the motherboard chipsets and data paths handle, using the current Xeons etc.?

Thanks

Are there any really big processor jumps coming soon? Are the Opeterons close to max design speed?

That's 3 Gb/sec, versus S-ATA's current 1.5Gb/sec. In a year or so that'll probably become standard.

PCI-X 133MHz slots (not to be confused with forthcoming PCI-Express) are good for a theoretical 1GB/sec.

Opterons have plenty of headroom yet, I would anticipate them moving up to 3GHz at least.

Cool :excl: :excl:

I/O Expansion 1 8x/4x AGP Pro
1 64-bit 133MHz PCI-X
2 64-bit 100MHz PCI-X
2 32-bit 33MHz PCI

I've got one of those, :wink: and I suspect the 100 mhz PCI-X aren't too bad, either.

* A PCI Express device will not have to share *any* PCI bandwidth with another PCI device, however, PCI-X will have to share bandwidth if there's another PCI device plugged into that PCI bus segment.

* PCI Express is a full-duplex bus, PCI-X is half-duplex.

* PCI Express will cost less overall.
