    UFS Pinpointing storage bottlenecks when using iSCSI vs DAS

    HI all, for various reasons (that shall remain unrevealed) I am considering moving my storage from my HP Microserver N40L to iSCSI. This will involve moving the HBA in the N40L to another server. The new server will be the iSCSI target and the N40L the initiator. Before I do this I am running...

    Other iSER module not present.

    I am trying to use the iser module as detailed in the man page's alternative method to building the kernel. I've checked both FreeBSD 11/12 and I cannot locate the module. Is there really a iSER module for FreeBSD?

    Other FreeBSD iSCSI iSER Target

    I dug around for an hour but what I found so far is that iSER is only supported in the initiator. And even for the initiator I need to recompile the kernel because the module seems to not be compiled in the distribution and as far as I read it needs "option OFED" (is it such a performance hit...

    I have been able to successfully boot FreeBSD 10.4 over iSCSi using net/isboot-kmod. However, once booted I continuously get the following message. iSCSI session is restarted This leaves me with an unstable system as random filesystem accesses will hang on zio->io_cv. Once this happens, the...

    Solved Can FreeBSD Serve Tape Drives as iSCSI Targets?

    Some background on my environment and use case: I would like to share my LTO5 tape drive via iSCSI with a server that will be doing backups to tape, but having the tape drive in a more convenient location to switch out tapes. The FreeBSD box is running pfSense and acting as a router (however, I...

    Other iSCSI Multipath

    Hi I was looking for some info about iSCSI, does it support multipath on a FreeBSD? I have found only really old discussions about that, and all were.. unoptimistic. Does somebody have tested it with FreeBSD 10.3 RELEASE? Thanks!

    Other iSCSI transfer: 12 TB job, 24 TB down, 10 TB up. How's that work?

    I set up a 16 TB zfs pool (vdevs are all 2x mirrors) to create a "life preserver" array for a colleague who needed iSCSI storage for his 12TB life's work online in a matter of weeks. I see there are different phases to an iSCSI transfer, but I don't see how anything the target would normally...
