在 ProLiant DL380 G6 上运行的 VMware ESXi 5.5 上未启用 HP Smart Array P400 写入缓存

  • 772

即使没有备用电池，我也在尝试在 Smart Array P400 上启用写入缓存。我们有一个由发电机支持的大型建筑范围的 UPS，因此断电的可能性很小，并且此 VM 主机服务器上的写入性能很糟糕。我已经安装了 HP VMware 驱动程序和软件，并使用 hpssacli 打开了写入缓存和无电池写入缓存：

但正如您所见，写入的缓存比率为 0%。我错过了什么？

  2. 这是一个俗气的解决方案。

    HP Smart Array P400 并不真正支持无电池缓存覆盖设置。

    • 但是使用 Smart Array P400 意味着您使用的是 HP ProLiant G5 服务器...
    • 这意味着您使用的是 2005-2008 时代的东西...... 10 岁。
    • 这表明您正在运行 VMware 不再支持的东西......
    • SATA 驱动器在该控制器上将速度降低到 1.5Gbps（而不是 3Gbps 或 6Gbps）；SAS驱动器的一半速度...
    • 这意味着您的性能将非常非常糟糕......即使有写入缓存。

    您可以尝试寻找电池，但服务器太旧了，没有人有新的健康电池库存。

    由于那一代服务器的市场价值约为 100 美元，因此这是一个艰难的用例。

    您确定要运行此特定服务器吗？
