Hello all... we're in the final stages of purchasing a NetApp F740 to host our Sybase (or Oracle, eventually) database on. The device will be populated with 18 gigabyte drives, to balance # spindles with total storage capabilities. At the moment, the 36 gigabyte drives don't look to be appropriate to our needs or cost-effective.
However, I'm concerned at the relative speed with which the 9 gigabyte drives were EOL'd and then became unavailable for sale. Is there a scheduled time-frame for EOL on the 18 gigabyte drives? Should I specify 36 gigabyte drives, just to be safe and have a reasonable time frame for continued acquisition of the same type of drive?
Thomas
P.S. Thanks to everyone who responded previously to my query about people's experience running databases off a NetApp... I'm confident now that this is a feasible solution, and that the benefits are pretty compelling. The last obstacle is simply arranging to actually demonstrate this working in a test environment, before going forward.

With how fast the 9GB drives were wacked (under 6 months from when we purchased our F720), I would guess it will be tomorrow or 6 months after you purchase your unit.

I would if I were you.
However, please remember that you do *not* need to have all the same size drives on your filer. Someone has recently noted that there is a performance penalty for having multiple size drives in the same RAID group, although personally I don't think it is a severe penalty in typical configurations. But you can always put drives of one size in their own RAID group.

Was there much of a price difference between the 18G and the 36G drives when you spec'd them out?

36 GB drives should be more cost effective since you have to buy half the number to shelves to accomplish a data requirement...
Assuming I'm figuring this properly- you'd have to buy 8 shelves of 18 GB drives to accomplish 1 TB of data. Alternatively you'd only have to buy 4 shelves of 36 GB disks to accomplish the same 1 TB. In the end, the offset is much cheaper to go with the latter. Of course this assumes a rather large data requirement, this may not be true with say a quarter TB or less.
One caveat to keep in ming when buying 36 BG disks however, if you plan to create more than one volume on the filer. Smaller disk sizes will be more flexible since the minimum volume size is 2 disks you may have better luck with the 18's if you're planning for smaller volumes.
