存储池配置里,还能建立cache读缓冲,log写缓冲,metadata元数据读写缓冲三种不同和性能有关的vdev。 cache读缓冲也需要内存容量支持,并不是越大越好,太大的可能会占用过多内存,降低存储池性能。建议容量是内存容量的5-10倍的nvme。 log推荐使用2或更多数量的高写入寿命固态硬盘通过镜像模式,并且超配设置将分区设置为...
HK-TrueNAS X10、TrueNAS X20、TrueNAS M40 和 TrueNAS M50 混合存储阵列使用cache来加速使用 RAM 和基于闪存技术(包括 NVMe、NVDIMM 和 SSD)的硬盘驱动器(HDD),以显着提高 I/ O表现。这种架构提供了闪存的性能和硬盘的容量,为用户提供了两全其美的体验。 对于实施以闪存为中心的数据中心的客户,TrueNAS 是一种全...
Windows下扫盘是能正常看到温度和所有S.M.A.R.T.信息的,我也不知道TrueNAS系统到底出了什么问题,所有SATA设备都看不到温度,包括4块希捷银河8T和2块西数蓝盘固态,只有nvme固态能显示温度。 运行手动S.M.A.R.T.检测会卡在10%,就像这样,但是每天计划执行的S.M.A.R.T.测试并不会报错,也很奇怪。 而手动执...

The M-Series can be both. Combining vast system RAM, NVDIMM, and NVMe flash as layered cache provides industry-leading read and write efficiency and optimizes the performance of the primary storage media. Flash pools are supercharged, and high-density disk pools deliver low latency flash performa...
TrueNAS Scale中默认把50%的内存划作ZFS Cache,但对大内存的机器(比如128G、256G等等),排除掉...
Hi guys-We a large 500 TB pool with 4x 8 TB nvme cache drives. From what I can see with zpool iostat -v, they are barely touched. What optimizations can I do to force more items to be placed into the read cache for faster repeat access? We are mostly storing large photos and vide...
Sequential or streaming workloads need very fast and low-latency L2ARC devices.Enterprise-grade NVMe devices are recommended. The device capacity is dependent on how much faster the L2ARC device is over the data storage devices. The faster the L2ARC device over the storage, larger capacity become...
