    Use SSD Boot-disk as ZFS cache

    A SSD is by default much faster because of the extreem low latancy en the minimaal faster througput then a converntional drive. So can I assume in any case the use of a partition (slice?) is a smart thing to do for use as read cache?

    Use SSD Boot-disk as ZFS cache

    Hi all, I am working on my ZFS pool layout with 8 disks and I am thinking about 2 striped vdevs containing 4 disks with RAIDZ. For me speed is important, so I doubt about the RAIDZ and maybe I switch to 4 striped vdevs with 2 mirrored disks. To further improve speed, I did read about...

    Good 8 ports SATA Controller

    Is there a valid/good reason to go for the more expensive 3Ware 9650SE-8LPML over the less expensive Supermicro AOC-USASLP-L8i in terms of support, quality or speed?

    Good 8 ports SATA Controller

    Did not know it is possible with just a cable. Does it have negative impact on performance, 4 SATA disks on one SAS connection?

    Good 8 ports SATA Controller

    Due my lack of knowlage (sorry for that): How can I connect 8 SATA disks to a 2 ports SAS connector in case of the AOC-USASLP-L8i?

    Hi Knarf, how does the Supermicro perform and what is you setup in terms of number of disks, ZFS layout?

    Good 8 ports SATA Controller

    I am relative new to freeBSD (some weeks ago I finished my first pfSense installation and I am running freeBSD 9.0 Stable in an Virtualbox environment for gaining knowledge about installing en using freeBSD). Your answers gives me fast and high quality information. Now I feel confident enough to...

    Good 8 ports SATA Controller

    Ok, so the best way to go is export each drive as single volume. Sounds like instructing the controller to do so. How do I instruct the controller? Install freeBSD (9.0 stable) and use some CLI commands? Or using the Webinterface, but how can I get there when freeBSD is running?

    Good 8 ports SATA Controller

    Wow, thank your for your detail information. Support If I understand you correct, the most save solution is the 3Ware 9650SE-8LPML for a 8 port SATA. This controller is a little old, but wel supported. Correct? Speed Can I expect a 300 MB/sec liniair write and read throughput in ZFS...

    Good 8 ports SATA Controller

    Thank you for your answer. your suggested controller is from 2007, so 5 years old and still expensive (for home use). After some more searching I found the LSI SAS3081E-R-SGL. Less expensive and from my point of view comparable to the older card (no hardware expert). I found a post where...

    Good 8 ports SATA Controller

    Ok, this is a reply to my own post to add some extra information It's for home use and I want to get the maximum out of ZFS, so I intent to put in 4 striped vdev's of 2 mirrored disks. SATA II should be enough for conventional disks (NON-SSD), so I am looking for a stabel well supported SATA...

    Good 8 ports SATA Controller

    I want to build a FreeBSD 9.0 server (my first) with 4 Seagate Barracuda ST3000DM001 harddisks (expandable to 8) and use them with ZFS. The onboard controller is for a SSD and serving the FreeBSD system. After a lot of reading in this forum, using Google for hours, I do not feel comfortable...
