Question

can i install ubuntu on RAID?

Answer 1

Does the Ubuntu Server support software RAID?



Software RAID is often a less expensive, and more flexible alternative to hardware RAID. Furthermore, there's no special hardware required for software RAID -- just disks.



The Ubuntu Server installer supports partitioning and installation onto RAID0 (striping), RAID1 (mirroring), and RAID5 (striped set with distributed parity), with a few caveats.



Some considerations...



LVM is generally preferred over RAID0 to attain the same effect (concatenating storage across multiple disks), as it allows for more flexible extendability.

This might make sense for auxiliary storage, but you would not want to spread your root filesystem over multiple disks, as a failure of any disk would render the system unbootable.

For full redundancy of the entire system, you can install the Ubuntu Server to a root filesystem on a RAID1 mirror.

If you wish to install the Ubuntu Server to a root filesystem on a RAID5 set, you will need to create a separate /boot filesystem on a RAID1 mirror.

Answer 2

Ubuntu server and ubuntu desktop are essentially the same OS. The main difference is that ubuntu desktop comes with the GUI and the server does not.



If you're familiar with windows server 2012, it's like saying server 2012 core vs. server 2012 with desktop experience enabled.

Answer 3

confident. should not be a difficulty as long via fact it has adequate reminiscence and disk and so on. you could take a glance indoors the Ubuntu boards in case you want tech help. Asking indoors the cricket communicate board won't get the final factor of seriousness in destiny.
