    值得一试，概述了很多：

    高水平
    1-仅AHV
    2-1、3、4节点簇大小
    3-身份验证与.NEXT帐户有关
    4-必须启用回家并运行
    5-升级到最新的Verisons出现时是强制性的，并通过第3和第4点执行

    另外，我忘记了最后三个

    6-由于在CE中的虚拟LUN传递配置，因此性能不如商业速度快。
    7- CE的AHV（目前）与商业版本不符
    8 -NVME在CE中尚未支持

    \n
    \n6 - Performance is not as fast as commercial due to virtual LUN passthrough configuration in CE vs PCI passthrough on commercial
    \n7 - CE's AHV (currently) is not aligned with commercial version
    \n8 - NVMe is not yet supported in CE","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    嗨，乔恩

    6-由于在CE中的虚拟LUN传递配置，因此性能不如商业速度快。

    您能为我的知识解释有关虚拟lun通行证的更多详细信息吗？

    谢谢

    \nCan you please explain more detail about virtual LUN passthrough n CE for my knowledge?

    当然

    在广告中，我们将整个PCI附加的存储控制器（HBA）插入CVM，即“通过”到CVM中，因此控制器虚拟机看到HBA和附加的磁盘，就好像是裸露的磁盘金属机器，所以我们可以直接访问

    在CE中，并非所有用户都有可以进行PCI传递的HBA，因此为了确保更广泛的兼容性，我们实际上将每个磁盘作为虚拟磁盘转移到CVM。这涉及系统虚拟化软件“抽象”每个原始/物理磁盘并将其传递到CVM的单独。

    意思是，当我们必须在CE世界中进行IO时，它会击中该抽象层，从而击中CPU。我们做出的权衡使我们更容易在人们拥有的各种高端和低端系统上使用我们的软件。

    \nIn commercial, we take the entire PCI attached storage controller (HBA) and plug the entire thing into the CVM i.e \"pass it through\" to the CVM, so the controller virtual machine sees the HBA and the attached disks as if it was a bare metal machine, so we have direct access
    \n
    \nIn CE, not all users have HBA's that can even DO PCI passthrough, so to ensure wider compatibility, we switched to virtually passing each disk through to the CVM as a virtual disk. This involves the system virtualization software \"abstracting\" each RAW\/Physical disk and passing it up to the CVM's individually.
    \n
    \nMeaning, when we have to do an IO in the CE world, it hits that abstraction layer, and therefore the CPU. Its the tradeoff we make to make it easier to use our software on a wide variety of high end and low end systems that people have out there.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    你好，
    您将使用哪种HBA用于SATA？LSI 3008？;-)

    克里斯
    \nWhat kind of HBA would you use for SATA? LSI 3008? ;-)

    我会延续到 - 他们知道他们的HBA比我更好

    大多数HBA都支持SATA和SAS，甚至只是为了支持他们使用SATA的SSD。3008是一种固体产品及其当前的一代，因此它将支持基本的HBA模式，以直接访问所有磁盘，这是CE的首选路径。

    请注意，NVME何时进入CE，这将变得有些怪异，因为NVME将是PCIE设备，因此扩展器通常会更常见地是带有一些电池等的简单PCIE开关。
    \n
    \nJust be aware when NVMe makes its way to CE this will get a little weird since NVMe will just be a PCIe device so an expander will more often than not be a simple PCIe switch with some battery etc.","quoteUsername":"jrack","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    是的，Broadcom/Avago/LSI（今天被称为什么）几乎拥有芯片市场的突袭，因此所有的大型玩家都在ASIC上提供定制固件。类似于Cisco Nexus主要是标准的Broadcom商人硅，而NXO上的NXOS则是标准的。

    我的意思是，如果您拥有H730或任何更名的LSI TAHT支持JBOD模式，那么它就比这样做了。

    \nI mean if you have a H730 or whatever rebranded LSI taht supports JBOD mode than go for it.","quoteUsername":"jrack","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    “无法更新社区版中的SMTP服务器详细信息。”：翻白眼：

    设置后，我很失望地发现限制不是透明的，只出现在使用过程中。例如：

    • 如果您的集群存在问题或严重问题，您不会知道。相反，如果您尝试配置电子邮件警报：“无法更新社区版中的SMTP服务器详细信息。”
    \u201cCannot update SMTP server details in Community Edition.\u201d\u00a0\":rolling_eyes:\"<\/p>

    After the setup, I was disappointed to find that the limitations are not transparent and only appear during use. E.g:<\/p>

    • You don\u2019t get informed if there are problems or serious problems with your cluster. Instead you get the following message if you try to configure email alerts: \u201cCannot update SMTP server details in Community Edition.\u201d<\/li><\/ul>","quoteUsername":"Ibinema","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
