Hi Everyone
I am looking at setting up a File Server that uses ISCSI storage. It is the first time I have done this, so I am wanting to get peoples thoughts on whether for CentOS systems you should use Hardware based ISCSI HBA's?
If so do I need to be careful about what HBA I use ? Currently I am looking at purchasing a Dell System using Broadcom ethernet cards/ ISCSI HBA. From google searching it seems QLogic HBA's are quite popular ?
Any suggestions or experience you can offer appreciated.
Have a nice day

Depends on the load, most file servers aren't that busy in which case software iSCSI would be fine. HBAs are good for things like booting via iSCSI. Qlogic HBAs are good yes though they are limited to 1Gbps of throughput. Chelsio seems to be popular as well for 10Gbps at least.
Many modern broadcom chips have iSCSI offload ability as well, though I haven't tested it myself under linux at least.
What iSCSI system will you be connecting your servers to?

Hi, Thanks for the response.
At the moment I'm not exactly sure what ISCSI storage will be bought, but hopefully something like http://www1.ap.dell.com/nz/en/business/storage/equallogic-ps4000-series/ct.a...

Don't know what your requirements are but file serving could be handled by DAS at a lower cost -

I wouldn't go DAS if you plan on adapting the iSCSI stuff to run other applications such as virtualization or clustering or something.
just a thought..

Thanks for the suggestion. But the plan is to eventually connect a number of Linux, Mac and Windows servers to separate LUN's on the ISCSI device
