AoE, iscsi and storage

Hi guys, I'd like to share experiences and knowledge about what should I use to install on a new storage server (with a lot of disks) in my network. What I want, is to move all domU's storage to this new storage server with AoE, iscsi or another thing. question:

1. Should I install openfiler or freenas or other NAS software on the storage or simple install a fresh linux operating system e.g, debian and use it as the AoE or iscsi target server?

What do you suggests? use a NAS software or not?


The scenario is:

1. several domU's working with the storage on the new server
2. Cisco switch between storage and domU's with LACP configure on the two ports used by the server
3. storage server with two NICs using bonding (802.3ad)

thanks tons
regards,
Israel.

ISCSI-INITIATOR(8)					    BSD System Manager's Manual 					ISCSI-INITIATOR(8)

NAME
iscsi-initiator -- refuse-based iSCSI initiator SYNOPSIS
iscsi-initiator [-46bcDfVv] [-a authentication-type] [-d digest-type] [-h target-hostname] [-p target-port-number] [-t target-number] [-u username] mount_point DESCRIPTION
The iscsi-initiator utility can be used to access an iSCSI target, such as iscsi-target(8), to access block storage which has been exported. Information pertaining to the target is displayed underneath the mount point, along with the device corresponding to the storage which the target exports. The various arguments are as follows: -4 Use an IPv4 connection to the target. -6 Use an IPv6 connection to the target. -a authentication-type Use the specified authentication type when communicating with the target. The possible values are chap, kerberos, srp or none. The default value is none. -b Show the storage as a block device. -c Show the storage as a character device. -d digest-type Use the specified digest type when communicating with the target. The possible values are header, data, both, all or none. The default value is none. -D List the LUNs on the specified target and exit (i.e. do discovery only) -f Show the storage as a regular file. -h hostname Connect to the iSCSI target running on the host specified as the argument. -p port-number Connect to the iSCSI target running on the port specified as the argument. The default value is 3260. -t target Connect to the number of the iSCSI target running as the argument. -u username Use the specified user's credentials when logging in to the iSCSI target. There is no default. -V Print out the version number and then exit. -v Be verbose in operation. The refuse(3) library is used to provide the file system features. The mandatory parameter is the local mount point. This iSCSI initiator presents a view of the targets underneath the mount point. Firstly, it creates a directory tree with the hostname of the target, and, in that directory, a virtual directory is created for each target name exported by the iSCSI target program. Within that virtual target directory, symbolic links exist for the hostname (for convenience), a textual representation of the IP address, the iSCSI tar- get product name, the iSCSI target IQN, the iSCSI target vendor and version number. One other directory entry is presented in the virtual target directory, relating to the storage presented by the iSCSI target. This can be in the form of a regular file, which is also the default, a block device or a character device. Please note that the iscsi-initiator utility needs the ``puffs'' kernel module loaded via modload(8) to operate. EXAMPLES

puffs(3), refuse(3), iscsi-target(8) HISTORY
The iscsi-initiator utility first appeared in NetBSD 6.0. An earlier version called iscsifs was available in NetBSD 5.0 in source format only. AUTHORS
The iscsi-initiator utility was written by Alistair Crooks <agc@NetBSD.org>. BUGS
iscsi-initiator currently only supports a CHAP challenge length of 16 octets. Other initiators support up to 1024 and thus it is expected that most targets will also support such lengths. This means that CHAP compatibility with other targets apart from iscsi-target(8) is likely to be poor. To workaround this, please use authentication type none by not specifying a username with the -u option. BSD
