At first I just wanted to see how much work it would take to port ZFS to FreeBSD. I started by making it compile on FreeBSD, and once I did that, I was quite sure it would take at least six months to have the first prototype working. The funny thing was that after another week or so, ZFS was running on my test machine
Also, note that ZFS spawns a lot of threads for concurrent IO. So, enable NCQ (check queue length in /sys/block/<drive>/queue/nr_requests) on the drives if it is not set already. Invest into some SSD drive(s) as the L2 cache, which will speed up random IO ops tremendously.

Is it a bug or a feature that the solaris iscsi initiator isn't able to connect to an iscsi target on the same machine, using either the 127.0.0.1 localhost address or the machine's own ip address?
During the last couple of weeks I worked with a customer who bought a Sun Fire X4500 server (you know, Thumper). The plan is to run Solaris ZFS on it, then provide big iSCSI volumes to the video editing systems, which tend to be specialized Windows or Mac OS X machines. Wonderful idea: Just use zpool create to combine a number of disks with some RAID level into a pool, then zfs create -V to create a ZVOL. Thanks to zfs shareiscsi=on, sharing the volume over iSCSI is dead easy.
By integrating state of the art server and storage technologies, the Sun Fire X4500 Server delivers the remarkable performance of a four-way x64 server and the highest storage density available, with up to 48 TB in 4U of rack space. This system also deliv
ZFS is a new kind of filesystem developed by Sun Microsystems that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. Now thanks to the magic of Open Solaris, we have ported ZFS to the Mac OS X pla
In a project originally funded under Google's 2006 Summer of Code program, Correia has converted the ZFS implementation from OpenSolaris into a server or daemon program that runs on Linux.
Due to the recent surge of interest in porting ZFS to the Linux kernel (if you are in the mood to read dozens of messages, see this thread, the follow-up, plus this one and one more), I'd like to offer my view on things.
ZFS snapshots with 'zfs send' and 'zfs recv' is a better way. Due to its architecture, snaphots in ZFS are very fast and only take up as much space as much data has changed. For a typical user, taking a snapshot every day, for example, will only take up a
Apple is doing something really cool with storage - not to discount their laudable RAID product - and that something is called ZFS. The bright side of the Leopard slip: more time to integrate ZFS is a Good Thing.
