"iSCSI killer" Native in Linux

Posted by ryuzaki0 on from the making-the-world's-storage-better dept.

jar writes "First came Fibre Channel, then iSCSI. Now, for the increasingly popular idea of using a network to connect storage to servers, there's a third option called ATA over Ethernet (AoE). Upstart Linux developer and kernel contributor Coraid could use AoE shake up networked storage with a significantly less expensive way to do storage -- under $1 per Gigabyte. Linux Journal also has a full description of how AoE works." Note that the LJ article is from last year; the news story is more recent.

  1. Cheaper? by DSW-128 · · Score: 4, Interesting

    I guess I don't really see how it's cheaper that iSCSI? Sure, there's less overhead from the lack of TCP/IP, so you may not need as massive a network to drive it equally. But I've been under the understanding that iSCSI doesn't require SCSI drives, so you could build an iSCSI target out of the same machine/drives as an AoE host, correct? For some applications, I think the lack of TCP/IP might be a benefit - less opportunity to hack. (Then again, I'd expect anybody deploying something like this or iSCSI would drop the few extra $$$ to build a parallel network that transports just storage.)

  2. iSCSI killer? by apharov · · Score: 4, Interesting

    In the context of using this in low-cost environments with Linux I can hardly see how this could kill iSCSI. Last week I implemented an iSCSI setup for about 500 euros (target serves out 500GB disk space for non-critical backup) using standard components, FC5, iSCSI Enterprise Target and Microsoft iSCSI Initiator.

    Works great and is a lot (>10x) faster than the about similarly priced NAS device that was used for the same task before.
