[dba-Tech] iSCSI Openfiler SAN

Even though I have not heard anything about iSCSI target, it does sound like a very descent product at a decent price. I have been slowly replacing my home office network with GByte LAN cards, switches and router. The internal performance is really stellar but Internet is only marginally improved but that is probably because my ISP throttles back performance...

On a Linux box the performance should be better as there is less overhead than on Windows products.

Keep me posted on what you learn and any performance and setup issues.

Hi all

Are any of you using iSCSI to attach network storage?

I happened to locate this free server (iSCSI Target) which offers both SMB/CIFS (Windows share), iSCSI Target server, NFS, FTP, UPS, HTTP/WebDAV, LDAP, and rsync services, all controlled from a nice web interface:

  http://www.openfiler.com/

It seems to be well beyond the "normal" NAS appliances but is free to download and use from a single ISO install file or as ready-made machines for VMware  - both in 32- and 64-bit. It runs on a rPath locked down Linux.

Documentation is sparse (manual is €40 to buy) but I found this beginner's guide:

http://www.petri.co.il/iscsi-san-vmware-esx.htm 
http://www.petri.co.il/use-openfiler-as-free-vmware-esx-san-server.htm 
http://www.petri.co.il/connect-vmware-esx-server-iscsi-san-openfiler.htm 

and this guide, How to connect your Windows 2008 Server & Vista PC to your iSCSI SAN:

http://www.windowsnetworking.com/articles_tutorials/Connect-Windows-Server-2008-Windows-Vista-iSCSI-Server.html 

All very nice, but big question is of course performance? It could be fine to set up a box with an array of 2 TB drives and off we go. But?
Would I need 10 Gbit NICs and switches? These are still quite expensive.
