FC60 and HotSpare
I have a FC60 disk array with 10 x 36Gb disks and I have defined one disk to hotspare.
Now, I will buy 20 x 18Gb disks.
I need to add one hotspare more (1 x 18Gb) ??
thanks

Re: FC60 and HotSpare
The difference is that, as a hot spare, you don't get to use the capacity of that disk - it just sits there, lonely, empty, waiting. With a "cold" spare, the disk that would have been wasted can be used for data. If you have abundant capacity, then hot spare is probably the way to go. If you're trying to squeeze as much data as you can into the space you have available, then "cold" spare makes more sense, assuming you monitor the array closely in order to detect and replace failed drives.

Re: FC60 and HotSpare
the HotSpareDisk in your FC60 is a so called GlobalHotSpare.
That means that this disk will "replace" failed Disks in every LUN of you FC60.
So it is important to always choose the biggest Disk (in your case the 36Gig disk).
HP recommends one HotSpare per SC10 if you want`t HA but i think that this is too much in most cases.
So the answer to your question is:
No, you don`t need to add another HotSpareDisk.
But if you want to add one you have to choose a 36Gb disk.
Best regards
