@Morten,

would putting the Diskstation/Cubestation/Rackstation series of Synology somewhere in the league of much more expensive systems necessarely be a bad thing? I don't think it is.

Of course it would be nowhere nearly comparable to the professional SAN solutions which posess much more storage capacity, bandwidth, nic bonding and fail-over, etc. It would, just like all the other features, just be yet another cherry on the feature-pie :).

I am pretty convinced that the large businesses, who find the NAS functionality or limited funtionality as a server too limited for their business, are not the target audience for the Synology products but smaller companies who already have the rackstation-products in use might as well be able to benefit from iSCSI, as will the tech-enthousiastic home users.

At my work, we use an old server with a big RAID array with "Openfiler" (www.openfiler.com) as easy to set up, low-cost SAN and it performs pretty well. It works with the open-iscsi implementation as well as the iscsi implementation of Cisco. It uses "IETd" as iSCSI target.

For a developer like me who doesn't want to spend a lot of time managing a storage server the solution of a NAS with iSCSI would be very nice. Then there is more time left to do other nice things.

I really want to stick with Synology as I love the firmware (does everything I need it to do) and the hardware is stable, quiet and well designed but I feel strongly swayed by QNAP's iSCSI implementation.

I don't prefer QNAP's firmware however iSCSI would simplify my backup requirements so much (with iSCSI I could just target my Syno box as a Time Machine Mac backup) that I am considering switching (or at least running 2 separate boxes) for this feature alone.

Synology - pretty please - consider iSCSI support!

Same here.

Synology,

Can we have an official statement if/when iScsi will be supported and on which platforms ? People are asking for it for years and competition has it.

Kind regards

Any news ?

I'm looking at a DS409+ and another brand who has iSCSI.

If Synology can respond that iSCSI will be added to the DS409+ I will certainly buy the DS409+ otherwise will go to the competition.

i'd really like iSCSI support too, as it would easy some application pains i have. sadly still no official comment from synology on that topic. not interesting enough (although the competition offers it) or simply forgotten?

This is really looking nice. Especially the iSCSI and internal firewall. Finally no worries to have direct access of the DS to the intarwebz :D

Can someone explain the benefit with iSCSI over a mapped network drive? The latter I have, and it is (almost) like a local drive.

Thanks for the info!

With iSCSI, your client computer will see a defined amount of space like a 'real' block device. That is, you can format (and even partition) that device with any file system you want and access it if it were a local device like a harddisk.

With a mapped network device using NFS or Windows CIFS/SMB, you can always encounter certain problems like locking issues or other issues with applications that would use features of a filesystem (like ext3 or ext4 in Linux) that are not available over NFS or SMB.

iSCSI = "SCSI over IP"
Just imagine that your NAS becomes a local hard drive, you could even boot on it with special (expensive) network card.
iSCSI turn your NAS into an "hard drive over IP" will all benefit and flexibility this will include.
For example, imagine that your local hard drive is far away from 500km in distant backup matter. This opens new easy backup possibilities.
This will also avoid problems with applications which sometimes just does not support network shares.

Also, in theory it means that data access performance should be increased (but we will wait to test it before to affirm this).
iSCSI works at block device level. In a general matter, iSCSI opens new possibilities of uses of your NAS.
Anywhere TCP/IP goes, iSCSI goes.

@Zouk !: Thank you for your clear response.
  1. Could broken or lost IP packages corrupt the iSCSI files system?
  2. Can unauthorized persons sniff or alter IP packages and (by doing so) obtain illegal read/ write access to iSCSI data?
  3. Does iSCSI allow admins to use an ext4 file system (which is more reliable then ext3) on the NAS?
