The following file system features and enhancements have been added to the Solaris 10 8/07 release.
This Solaris release provides support for iSCSI target devices, which can be disk or tape devices. Releases prior to Solaris 10 8/07 provided support for iSCSI initiators. The advantage of setting up Solaris iSCSI targets is you might have existing fibre-channel devices that can be connected to clients without the cost of fibre-channel HBAs. In addition, systems with dedicated arrays can now export replicated storage with ZFS or UFS file systems.
You can use the iscsitadm command to set up and manage your iSCSI target devices. For the disk device that you select as your iSCSI target, you'll need to provide an equivalently sized ZFS or UFS file system as the backing store for the iSCSI daemon.
After the target device is set up, use the iscsiadm command to identify your iSCSI targets, which will discover and use the iSCSI target device.

The extended FILE space feature supports an addition, F, mode to the fopen library command. The F mode enables the opening of files beyond the 255 limit. This feature enables the developers to use the fopen command to handle file descriptors up to the limits set using the limit or ulimit commands.
