No, the option is not available on the R610.  The location for installing the cards are not the same, so the R610 will only handle the single SD card option.  Regards, 
We have a couple Dell PowerEdge R610 rack servers that we purchased with the 1GB SD flash modules.  We recently purchased a PowerEdge R620 and got this one with the dual 1GB flash module that allows you to mirror a couple 1GB flash cards.  I tried to get information from our new account rep but he is turning out to be very unresponsive in getting me information on my inquiries. Can anyone verify if there is a similar dual SD card unit that can be purchased for the R610 servers that you can now get for the R620 servers?  I would like to replace our single card module in the R610 with a dual card module if that is at all possible. Thanks.
