Today we will look at how to configure iSCSI service on FreeNAS.
FreeNAS is a free and open-source software network-attached storage (NAS) system based on FreeBSD system. FreeNAS supports Windows, OS X and Unix clients and various virtualization hosts such as XenServer and VMware.FreeNAS supports the OpenZFS files system which provides data integrity checking to prevent data corruption, enable point in time snapshotting, replication and several levels of redundancy including striping, mirroring, striped mirrors (RAID 1+0), and three levels of RAID-Z.
To configure iSCSI service on FreeNAS, please follow steps below:
1.Login to FreeNAS web administration:
