performance difference between promise tx300 and sm saslp

[crankbearing]

I am in the midst of building my new server and in my old machine i have two PCI Promise tx300 4 port cards and they were pricey when I bought them a few years back, I am wondering how much of a difference I will see by using a supermicro saslp pci-e in the new machine compared to just re-using the promise cards.

 

this new Asus F1A75-V Pro has 2 pci-e slots x16 and x4 and 3 pci slots the same board in the -evo model actually has 3 pci-e 2 at X8 speeds and 2 pci. so I was thinking I may be able to add a saslp AND use my promise cards at the same time.

You can re-use the Promise cards, but you will not get the maximum speed possible for parity checks.

I.E somewhere from 60,000kb/s to 80,000kb/s with pci-x or PCIe.

 

The boards you suggested are not PCI-X they are PCIe and regular PCI. (133MB/s)

 

Chances are if you are using the promise cards in a current configuration, you can use them in the new configuration with the same level of performance.

 

I would suggest putting parity and your largest newest drives on the motherboard ports. Oldest drives on the promise ports.

thanks weebo,

 

yes not sure where I came up with the pci-x idea. I think I have blurred vision since I have been reading reviews and specs for the past few days and getting confused - lol.
