ZFS与硬件RAID控制器不兼容的主要原因在于两者在数据管理和冗余方面的设计理念不同: 数据管理方式不同:ZFS通过文件系统层面的校验和和冗余机制来管理数据,而硬件RAID控制器则在硬件层面实现数据冗余和故障切换。 数据路径冲突:当ZFS运行在硬件RAID控制器之上时,数据需要经过两层冗余机制的处理,这可能导致性能下降和复杂性...
I start here because, perhaps like you, I’ve always felt safer with hardware (HW) RAID — even though some pretty cruddy HW RAID has shipped. In my case I trace that back to the technologists at Veritas who, IMHO, never really “got” the enterprise — although the OpenVision guys ce...
Do not use ZFS on top of a hardware RAID controller which has its own cache management. ZFS needs to communicate directly with the disks. An HBA adapter or something like an LSI controller flashed in “IT” mode is more appropriate. ...
the UFS file system living on top of the RAID transform believed that it was dealing with a si...
Before diving into the hardware or software RAID setup, it’s essential to ensure your environment is ready. This includes: Installing ZFS: Ensure that ZFS is installed on your system. For most Linux distributions, you can install ZFS via the package manager (e.g., apt install zfs on Ubunt...
It is recommended that you disable this feature for the zpool you are using with Docker, unless you are using SAN, NAS, or other hardware RAID technologies. ZFS Caching: ZFS caches disk blocks in a memory structure called the adaptive replacement cache (ARC). The Single Copy ARC feature of...
The following considerations might help you determine how to configure ZFS with other hardware or software storage solutions:If you construct ZFS configurations on top of LUNs from hardware RAID arrays, you need to understand the relationship between ZFS redundancy features and the redundancy features ...

Exceptionally simple deployment with "First Run Wizard" Minimalistic system requirements allowing it to repurpose your aging hardware: minimum 4 VCPUs and 4GB of RAM (8 vCPUs and 16Gb of RAM if ZFS is used) Not only ZFS but also Linux Software RAID and hardware RAID support ...
Actually ZFS's copy-on-write mechanism is one of the reasons this is more the case for ZFS then traditional systems. Further more arrays are managed in the systems memory, which isn't the case for hardware RAID for instance. Hardware RAID has dedicated memory. I'm not saying tha...
