Openfiler

Openfiler is an open-source "storage management operating system" that takes the Linux OS and makes it into a SAN controller. It can all be configured with a web browser. It can act as both SAN or NAS. It supports multiple iSCSI targets with multiple LUNs.

A Step-By-Step OpenFiler tutorial by David Davis: “Use OpenFiler as your Free VMware ESX SAN Server“ and how to configure for a static IP.

Another free option: StarWind. Their free version supports up to 2TB.

"R-Studio is a family of powerful and cost-effective undelete and data recovery software. Empowered by the new unique data recovery technologies, it is the most comprehensive data recovery solution for recovery files from FAT12/16/32, NTFS, NTFS5 (created or updated by Windows 2000/XP/2003/Vista), HFS/HFS+ (Macintosh), Little and Big Endian variants of UFS1/UFS2 (FreeBSD/OpenBSD/NetBSD/Solaris) and Ext2FS/Ext3FS (Linux) partitions. It functions on local and network disks, even if such partitions are formatted, damaged or deleted. Flexible parameter settings give you absolute control over data recovery."
