I have been doing alot of research on the different types of storage that can be built using various linux projects. I was thinking I would start a work log of the project. I am aiming for 2-4Tb of usable space. Here are a few of them. http://www.openfiler.com/ http://www.freenas.org/ http://www.opensolaris.org/os/community/zfs/ I have tested the above dists, and they are all quite good. They have different features and problems. The biggest problem I will have is getting HBA's to suit the different Linux operating systems. Openfiler This has really good iSCSI support. Supported SATA cards. SIL3114 Onboard NV SATA ports NF4 BC4852 (Doesnt seem to detect all drives, might be raid firmware like 3114) Freenas This has been around for a while. It does samba support really well. However it would be nice to have a bit more. ZFS on Solaris The "best" filesystem, that I can see. It features alot of really smart code and ideas. Would make building a machine cheaper, and the files more reliable, mabey faster Suggested Hardware Platforms Intel i845, Pentium 4, Onboard SATA,PATA Intel P965, C2D, SATA cards (ICH support seems lacking) AMD X2 NF4, DFI SLI, 4 onboard nv ports, 4 onboard SIL3114 ports. Suggested Raid/SATA HBA Cards 3Ware/ACC Acera Promise LSI Megaraid Adaptec SIL3114 Syba 3114. Flashed to non raid. Marvell Suggested Cases External SATA Case Not really looking at this, but there is a multilane external enclosure http://cgi.ebay.com.au/4x-MULTILANE...oryZ3757QQrdZ1QQssPageNameZWD2VQQcmdZViewItem Internal SATA Cage There was a few server cages that would fit a normal case, and provide hotswap rails. link There is the Coolermaster 4in3 device, which I already have a few of. link 3Ware cage. This is a SAF-TE, which allows status lights. Unlike any of the above. SATA Server Case Chenbro RM4146 4RU 16 Hotswap SATA Rackmount Case Here are a few things to look out for. https://wiki.ubuntu.com/ZFS ZFS on Ubuntu. Here is a sneek preview of a Openfiler I just got up and running.
