    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    I'm running Napp-it 0.8 without problems, should I follow the rule of "if it's not broken, don't upgrade ?" or is it relatively riskfree to upgrade to 0.9 ? Has anybody got VAAI working with Comstar and NAPP-IT ?

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    THANKS !! Will you be starting a FAQ or Wiki type of FAQ so that answers don't have to be repeated. While your quickstart is great, I find that there are things that we need that are already there in your GUI but we are just not finding it.

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    The challenge is that I want to have a text base for 1 reason, when I use the text base and when I use the NAPP-IT web gui, I can see the commands sent by NAPP-IT and that helps me.. so that's the MAIN reason and if I can get that back, I'll be real happy !!

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    How do I find out if I've install OI in server mode (with desktop) or workstation mode ? When I install OI in server/text mode, I can see commands appearing at the shell on I use the Web-Gui, but I cannot see that currently...

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    _Gea, I'm using OpenIndiana 151a3 (desktop) and NAPP-IT. I've multiple (5) Network interfaces and I've tried creating FCoE interfaces. Every time I reboot the FCoE interfaces would disappear. Is this something to do with NWAM or the fact that I'm using desktop rather than server ? I wanted...

    ZFS Deduplication requirements and performance

    OK, Thanks to all who replied. I've testing with a small box. 6 disk in 3x mirrors in vdev. Right now, I'm hitting deduplication rations of 22x to 24x . Yes, this is pretty much test environment. But on to my next point. A 40GB file will takes approx 10 mins to complete copying. Will test and...

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    Does NAPP-IT works with NexentaStor CE ? I know the NexentaStor CE already has a GUI but just want to compare side by side.. Thanks.

    Please help - Dell SAS 6/i

    @Dalfo002, Just want to say THANKS and it works great. Not sure the benefit though as the performance seems the same and I could only select the first disk as the bootdisk. Exactly the same as the IR firmware. It hang when I attempt to login to the IR firmware.

    How to troubleshoot iSCSI timeouts on Solaris 11 with comstar

    Not necessarily. It could be the TOE implementation on the specific NIC that cut across different OS. It could be on either side of the coin, no easy solution, my bet would be to google "network performance" + your NIC model, and hope someone encounter a similar problem..

    How to troubleshoot iSCSI timeouts on Solaris 11 with comstar

    Check drivers. Check TOE (disable them), Receive Offload,etc. Try disabling some of these on ESXi as well.

    OpenSolaris derived ZFS NAS/ SAN (OmniOS, OpenIndiana, Solaris and napp-it)

    Couple of minor problem with Nappit 0.7l comstar so far. 1. iSCSI target created successfully but when I attempt to delete or edit it, nappit said no iSCSI target found. I managed to delete it manually using the following commands. stmfadm offline-target...

    ZFS Deduplication requirements and performance

    And I assume that you have run deduplication with my exact mix of VMs ? Why bother discussing if we are all going to be running SSD. 12 SSD is not exactly equal to 160 SSD. I would consider running 12 SSD as a read cache and in fact that's what I plan to do, but my specific question was more on...

    ZFS Deduplication requirements and performance

    In my case, snapshots won't be feasible. In addition, in my case, the clone VM grew much larger than the master VM. I guess the bottomline is that I probably need to test it out myself !!

    ZFS Deduplication requirements and performance

    My understanding is that deduplication cannot be turn off or on like that... Not sure if I'm right on this... My read on this was that deduplication doesn't slow down that much given enough ram. Essentially you are cutting down the amount of data written to disk...

    ZFS Deduplication requirements and performance

    ZFS Deduplication requirements and performance

    It's more of here, pick a number and scale that... and SSD mirrors for a pool is clearly unscalable... Beyond that, I'm specifically asking about deduplication and it's impact on performance.. NOT L2ARC and SLOG and their impact on performance in this thread. Much as I appreciate your input, it...

    Caviar Blacks: still top tier?

    Just bought a couple of Caviar Black. Feels pretty fast to me. I'm giving up on Seagate after so many years... just too high a failure rate.. but big capacity HDD is just too expensive right now... got to buy a couple more.. wish I didn't have to..

    SCSI U320 to SAS

    I have a HP MSA2000 which is basically SAS/SATA disk cage normally attached through a SCSI320 cable to a server. Is it possible for me to attach this to a SAS interface somehow ?

    ZFS Deduplication requirements and performance

    @All, Thanks. That's the clearest explaination I've seen in a while. Assuming that ram is sufficient to hold the DDT metadata. Would my main gain be over the HDD saving ? Or would there be significant performance improvement as well ? I guess my point is that as much as the space is...

    ZFS Deduplication requirements and performance

    I have search though and there seems to be various formula throw up for the amount of ram required for deduplication. Is the ram requirement based on the actual size (block) of the pool or the amount of data (block) used in that pool. I.e. if my pool is 2T and 50% utilized, is it based on 2T or...

    ZFS NetApp replacement

    Just a little input to return all those help from the others.. In order to use maximum ram, you need 2 CPU. The R710 is actually a nice solution.. It's LOUD ..Do your company already has 10GB switch ?

    I have 8 + 2 on the T610. 2 on the m/b and 8 on the SAS6/i . I don't have it with me at the moment and cannot confirm. Would also want to get some expansion cage and additional controller (hopefully SATAIII 6G instead of SATA-II with 3G). Any suggestion on a good/cheap one to get including...

    Please help - Dell SAS 6/i

    I believe it's integrated. The server is a T610. I guess I just need a IT firmware and if Dell has one, I won't mind but otherwise I'll considering if it's worth the risk to update a integrated card. Anybody knows a decent SATAIII expansion card that I can get for cheap ?
