NEXT - INSTALL SOFTWARE

The use of separate partitions for the /home and /var folders greatly facilitates disaster recovery and system stability.
Using the /home partition for DSpace system and data files is generally accepted Unix/Linux systems administration best practice.
And one NEVER installs operational software in a top level folder on a Unix/Linux server.

The following partition scheme is recommended.

/	ROOT partition, where all the system software is installed	10GB Minimum - 20GB preferred
n/a	SWAP partition	2x installed RAM
/var	VAR partition, where all the log files and database files are installed	10GB Minimum - 50GB preferred. This depends on how big your database index files get and how large the log files.
/home	HOME partition, where all the DSpace software files and bitstreams are stored	All the rest of the total disk capacity.

/dev/sda1 = / - is the root/system partition.
/dev/sda2 = is the swap partition and is not listed.
/dev/sda3 = /var - is the partition where the database and log files are stored.
/dev/sda4 = /home - is the partition where the DSpace application and assetstore are located.

Doing a manual partition setup can be confusing for those new to Linux. Below are some links to help.

+===RAID Array===
+When you new server arrives, you will need to setup a RAID array on the server. Consult the guide supplied with your server for RAID setups.
+ https://en.wikipedia.org/wiki/RAID
+At Stellenbosch we use RAID6 as policy on our critical servers.
