    ZFS based storage

    Thanks. Just so I can have a perspective of how many cores I'll need, can you tell me what type of load are you having? Say IOPS or MB/s?

    OpenIndiana/ napp-it + OpenSource Clustering/ High Availabilty

    Hi, I see. Is that how Nexanta works as well? If it is I guess they should really be calling it active-passive, not active-active.

    ZFS based storage

    You are right. Now that you mention this I do recall have seen something like this before. How many cores would be sufficient for the storage heads?

    ZFS based storage

    Okay 8 is a bit extreme and there maybe limitations. What sort of issues are you referring to? I'm running 4 VMs each with 1vCore on a quad core processor and realize it's better to overcommit a bit so at least we can multithread.

    ZFS based storage

    My preference is to find a commercial solution with support. But either I stick with EXT4 solution from QNAP, XFS from Open-E, the only commercial vendor now for ZFS are either Nexanta, InforTrend, etc and they all charge silly money. While I can pick up anyone of the Solaris derivatives and...

    ZFS based storage

    Sorry have gone missing for a few days. Have been searching to see if there are alternatives to a commercial vendor like Nexanta, except without the price they charge. There appears to be another one available soon but pricing is still out of my budget. Strange enough first time I come across...

    OpenIndiana/ napp-it + OpenSource Clustering/ High Availabilty

    Sorry given ZFS is not a cluster file system, the best we can do is an active-passive setup, rather than an active-active setup, right?

    Network speed for storage

    Okay so what you are saying is we'll reach IOPS bottleneck before link speed bottleneck. Can I ask what type of traffic are you serving for both of your iSCSI and non iSCSI setup? And you are saying 2*1Gbps * 1024Mb/Gb * 8/10 ~ 200MB/s only so it's not fast enough. Can I also ask what type...

    Open-E

    Hi, does anyone have experience with Open-E? What is your size of storage and use case? How is their product and support like? Thanks. www.open-e.com/

    Network speed for storage

    Okay sorry thought 4Gbps FC is more or less similar to Quad 1Gbps Eithernet. In this case which one is faster? Okay so I guess it's IOPS between the databases and the iSCSI targets. Sorry why can't we team up all 8 x 1Gbps for an effective 8Gbps connection via LACP?

    There is a 4Gbps selection.

    Network speed for storage

    Wow that should be fast enough to handle a SSD or the fastest enterprise SAS in RAID 0. What type of requests is your storage used for? Is it for office or web? Have you considered using the Intel QDR Infiniband cards? They appear to be cheaper than some Dual 10Gbps cards.

    Network speed for storage

    Sorry you are using Dual 1Gbps or Quad 1Gbps? What type of setup do you have and how is it used?

    Network speed for storage

    Curious what network speed people are using for connecting to the storage heads, and whether 1Gbps is too slow considering a sustained read / write speed of 100MB/s (800Mbps) is easily achievable and 200MB/s (1.6Gbps) is available for some of the enterprise SAS. If you can get the Intel®...

    share sas target between two initiator

    Are you referring to a setup like the following? http://www.dataonstorage.com/images/products/DNS/9470/CiB-9470_70-70_Configuration_HBA.pdf I spoke to them yesterday and this 70-70 setup was explained as a single domain setup. They also have another setup where with 12 disks shared...
