You should be showing total space of about 290gb, which puts you about 60gb short. What does disk administrator show for your total presented space? Raid 5 is x-1 for available space, so with 3 hdds installed, you have the capacity of 2. <BR /><BR />What does your ACU show for your configuration?<BR /><BR />Ciao,<BR />Greg Wed, 22 Sep 2004 11:51:04 GMT Greg Carlson 2004-09-22T11:51:04Z https://community.hpe.com/t5/disk-enclosures/smart-array-641-controller/m-p/3382453#M13656 I just bought a Proliant ML Server with three hard drives (146.5 GB) and it has included the Smart array 641 Controller, I would like to understand more how it works?...I read the information that is included but it wasn't enough for me, I need to understand better why I just see 2 partitions 1 with 12GB and another one with 220 GB....I am new in this and I would like to understand better how this raid works?...Thanks in advance!
