I've been looking at the TD230 Server to replace a 7 year old Win2000 box. In the past we have used a Promise SmartTrak RAID controller that allows us to setup a RAID 1 [mirror] with a 3rd drive used as a hot spare.
If one of the RAID drives fails, the hot spare drive is automatically switched over become part of the RAID.
Can I do the same thing with the Lenovo's RAID controller?
Both the built-in intel ESRT2 and discreet 9240-8i option (an LSI card) offer global hot spares.
