https://community.hpe.com/t5/netservers/lc2000-netraid-1si-raid-10/m-p/2801461#M3288 I have an LC2000 with 4 18GB drives which is currently set up without RAID, but I am going to convert to RAID 10 using a NetRaid 1si controller. All my drives were suppose to be identical, but looking at the output from a hardware inspection program I noticed the last drive is slightly different: <BR />0: HP 18.2GB A 80-SA40SA40 (18.20 GB) <BR />1: HP 18.2GB A 80-SA40SA40 (18.20 GB) <BR />2: HP 18.2GB A 80-SA40SA40 (18.20 GB) <BR />3: HP 18.2GB C 80-BX02BX02 (18.21 GB) <BR /><BR />So the fourth actually has 18.21GB space as opposed to 18.20. Is this going to prevent me from having all these drives on the same RAID 10 array?<BR /><BR />I'm planning to order 2 additional drives and configure as RAID 1 for OS with a split hotswap backplane for a second NetRaid 1si controller. Any other gotchas I should know about? I assume the 2 drives on the separate RAID 1 channel don't have to match these exactly.

It should just use 18.20 for each drive in the array.
