iXsystems has great products and great solutions that won't break the bank. Their TrueNAS stuff is unbelievable and if you are on a budget may I recommend the FreeNAS offerings. If you try the FreeNAS offerings it is best to take the 4 or 5 classes and take great notes or use some sort of video capture and record your class as there are a million ever changing parameters in the 50 different ways you can setup a FreeNAS box. My FreeNAS box is an iSCSI share using RAID10 for 20 large HDDs and for cache we deployed 960GB fast SSD. If you have questions just call Kevin at iXsystems and he will answer your inquiry or send you to someone who can better answer your questions.
