1/5/2024 0 Comments Openzfs san softwareIf your SAN does not offer its own secure write behaviour to protect its caches ex with a hardware raid + BBU nothing can protect the Lun at the end perfectly. This is why you should use a Lun directly from a storage VM. ![]() Using the ESXi initiator, create a VMFS fs and use it via vdisk is of course a bad idea for a storage server. You only avoid (lack) a mechanism to get informed on problems (due data and metadata checksums) or double metadata or superiour read caches or write cache protection on OS level (Slog) with a crash save Copy on Write write behaviour and Ransomware save readonly Snaps. If you want to avoid ZFS, you do not avoid write cache related issues or other problems. You can also use Open- ZFS on Linux with SAMBA but without the "it just works" experience of Solarish or with some restritions Free-BSD.Įvery solution must mount the Lun with an Initiator to use it like a local disk, put a filesystem on it (apfs, ext4, btrfs, ntfs or ZFS) where you can store your files and where you can share folders. A lot of features but mostly slower and with restrictions regarding ntfs ACL support or ZFS snaps as Windows previous versions. You can also use a Free-BSD appliance with Open-ZFS and SAMBA. ![]() Look at the commercial Solaris with native ZFS or the free Solaris fork OmniOS with Open-ZFS. As a frontend you can use the fast multithreaded Solarish SMB server with best support of ntfs ACL with ZFS ontop of your current Luns. Check if ZFS security is affected by your SAN. You can of course use your current iSCSI Luns with a ZFS appliance, create a ZFS pool and share it via SMB. You can use Windows server as frontend without the superiour ZFS features but with best of all SMB support. If you use currently a hardware raid adapter, you may need to replace with a HBA for ZFS software raid to install a new OS directly. ZFS is called the last word in filesystems.Ī ZFS appliance that offers SMB (and iSCSI) directly, with newest features and updates would be my suggestion. Under ESXi, you can use my free ZFS storage server template with OmniOS.įor a barebone setup, see napp-it // webbased ZFS NAS/SAN appliance for OmniOS, OpenIndiana and Solaris : Manual Napp-it // webbased ZFS NAS/SAN appliance for OmniOS, OpenIndiana and Solaris :Downloads Also a perfect solution for ESXi due its very low resource/memory needs, OmniOS Community Editionįor management you can use my napp-it free or Pro (with support and some extras) with iSCSI sharing as a ZFS filesystem property, more or less iSCSI sharing on/off. There is a long term stable, bug and security fixes every few weeks, optionally with support. ![]() Quite the smallest/ just enough storage systems with no more than FC/iSCSI, NFS and SMB is OmniOS, an OpenSource Solaris fork for production systems. A production use iSCSI framework is Comstar on Solaris based OSesĬonfiguring Storage Devices With COMSTAR - Oracle Solaris Administration: Devices and File Systems
