Raid 1+0 with msa1000 and two enclosures
Hello, I have a question about the configuration of a RAID 1 +0 with a MSA1000 with two enclosures.
My question is:
if I make a RAID 1 +0 with 4 drives of 300 GB using 2 drives on the first enclosure and 2 drives on the second enclosures in case of failure of an enclosure I can continue to work or I can not access the data.
Thanks

Re: Raid 1+0 with msa1000 and two enclosures
I believe the MSA Controller is smart enough to not pair up disks on the same bus, or at least that is what I used to tell my customers when working on the MSA1x00.
To be sure that your disks are not paired on the same bus, create an array with 2 disks at first. 1 from each enclosure. Then add in the 2 next disks to expand the array and extend your logical unit(s) if necessary.
Obviously, losing the MSA shelf means the storage is offline since the controllers are in that shelf.... but losing the second shelf should only degrade the array, not make it un-usable.
