Subject: Production iSCSI targets and initiators - msg#00162List: linux.iscsi.iscsi-target.develI'm sure this has been asked before, but I can't find an answer anywhere. What is the most stable and reasonably fast solution for an iSCSI target (and initiator, too): 1. Commercial or open source drivers? 2. Using hardware and software, or software only? 3. If hardware, what to buy for the target and HBA (needed?) Here's my scenario: 6 Linux servers running RHEL3, FC3 and FC1. Each has 730GB of RAID5 (6 x hotswap 146GB Seagate U320). I have a spare GbE NIC in each, connected to a dedicated GbE switch. I use NFS today to share between them. I would like to to share all this storage between all of them (6 initiators and 6 targets). Is there a benefit over NFS? Is it production stable (users from both US coasts every day, all day, servers up over 100 days)? Is it worth going the iSCSI path? Thanks for any answer you can help me with. ./adoram ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.

The reason that I have to send mail to this list is that I know people in this list has the same interest that I have - open source storage. We are all wanting to be able to centralize storage using free software. But have you ever thought about the hardware part of it. We are stuck with using expensive brand-name RAID chassis or storage. Of which are, somehow, proprietary in mechanism. Sometimes, the only generic factor is the hard drive. Even if you can find a cheap generic storage chassis there would be something different about it that makes it not work with other RAID/storage chassis. There is no "universal storage chassis". As a result there is no competition. What I am suggesting here is an "open frame" a (electro/)mechanical design of a storage chassis, which "generic" manufacturers have to comply with. My idea is to design the drive bay and drive carrier modules, chassis height, the backplane mechanism and electronics including hotswap, cooling, speed and temp. sensors, lights / LCD control panel, alarms, RAID controller bays, motherboard section, add-on peripherals, DC/AC power supplies /redundancy, cascading/interfacing, etc. Please, if you know of such a list or org then please direct me that way. I want to actively promote this idea. Let me know your opinion, ideas, flames... Also, let me know which is the best mailing list to start this from. TNX. P.S. This idea can be extended to "open frame" servers using ATX motherboards designed as "open frame". It is like "blade servers" minus the "proprietary design" and cost. It is like an 8U chassis that will fit about 8 motherboards - no chassis required ! Everything else is centralized. I can rant more about this but it is not related to this list. -- Jojo Pornebo Systems Administrator PRIDE Industries - "Creating jobs for people with disabilities" (916)788-2410 (916)813-9383 Cell jpornebo@xxxxxxxxxxxxxxxxxxx ========== ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
