    ZFS vs. BTRFS: Safest Choice for Dummies?

    This is not related to ZFS. On BSD and LInux you always use SAMBA that knows nothing about ZFS. Only difference are SAMBA settings and defaults by a distribution. ZFS related are only ZFS properties like aclmode or aclinherit that work on filesystem level not share level. Only when you use a...

    Best way to increase zfs read+write speeds

    With 189GB RAM all cacheable reads (ZFS does not cache files but small random io and metadata only) are already in RAM. I would also expect an L2Arc usage near to zero. ZFS writecache is always and only RAM (around 10% RAM, max 4GB as default) and readcache is always RAM that can be extended by...

    SMB Becomes inaccessible after a few weeks of uptime

    There is a known problem with 'can't get sid' that is fixed in latest OmniOS but that should not kill SMB. In general it is recommended to first update to latest stable (151044 ap) or lts (151046q) when problems occur as problems may got fixed in current releases, see Release Notes . Also check...

    Any reason for SAS over SATA in bulk storage (xxTB) HDDs

    Main advantaged for SAS over Sata - up to 2 x 24G instead 6G (better performance, HA/dual host possible) - up to 10m cables instead 1m - more robust and stable data transfers and expander usage - full duplex instead half duplex If you have the option, go SAS

    PCI passthrough to bhyve on SmartOS

    Manuals for SmartOS are here: SmartOS Documentation The community is small but quite helpful. SmartOS is much more minimalistic than Proxmox, resource wise more like ESXi but as a Solaris fork with a perfect ZFS integration and LX Linux zones/ Docker support, Bhyve and KVM. As a USB stick...

    Is a CPU required in motherboard that supports IPMI to control fans?

    Google for a "DC 12V PWM Fan Temperature Controller". They are cheap and you can control fans either manually or depending on temperature.

    SAS SSD or Nmve SSD

    In the end NVMe is faster but often not hot plug capable and limited in number of drives without a pcie-switch . SAS like WD SS530/540 or similar with 2 x 12G (or 2 x 24G) are nearly as fast as NVMe but you can use cheap SAS Jbod backplanes with expanders and up to 96 disks

    Minimal hardware for napp-it all-in-one?

    If you boot from an m.2 nvme you can passthrough onboard sata and other nvme (at least mostly, some nvme are only usable as vdisk)

    New Inception Vulnerability Impacts ALL AMD Zen CPUs Yikes

    Use operating systems that offer regular security fixes, avoid systems or appliances that does not - and keep them up to date. With such critical problems every hour can make a difference when your system is available from internet or unsecured local lan/wlan.

    Import Encrypted Logical Units

    If an encrypted filesystem is unlocked it behaves exact like an unencrypted filesystem. If it is locked it is still a ZFS filesystem from structure but with data and metadata encrypted. btw Even with a splitted filebased key like L1:L1 or webbased keys you can use prompt (enter key manually) to...

    Import Encrypted Logical Units

    Only datasets of type filesystem can be mounted and shown via ls. Logical units are a reference to a zvol dataset type (datasets=filesystem, snap, zvol) Zvols are datasets that are treated as blockdevice like a raw disk. You cannot mount directly. To use a zvol you need to create/import a...

    Help a ZFS Noob select SAS drives for ZFS pool?

    some thoughts I would not only look at cost per TB but also on loudness and energy cost (calculate 5-10W per disk), reliability (the more disks, the more bad disks), work/time to regain storage availabilty and resilver time that increases with large vdevs due low iops (calculate 100 iops per...

    Hardware for virtualization (ESXi preferred) and GNS3

    You have the three options - buy something from stock it just works, no work, no trouble if it fits your needs If you use a 19" 1u server, be aware they are loud, very loud - use a barebone More flexible, you can select CPU RAM, NVMe/discs Some shops offer to deliver ready to use otherwise...

    Hardware for virtualization (ESXi preferred) and GNS3

    There are some should haves for ESXi - capable for min 64GB RAM (ECC is nice to have) - CPU depending on needs - ESXi supported nic (avoid Realtec, Intel is good) - at least one M.2 NVMe for ESXi, datastores + VMs If you want to virtualize OSX>v12 you need an Intel CPU, otherwise AMD gives...

    Minimal hardware for napp-it all-in-one?

    Very small cases are itx but this limits your choices regarding expandability (more disks, HBAs, faster nics. Very small cases are often quite loud due the small 40mm fans. You have much more options when you choose the slightly larger uATX format and a small case for uATX boards with larger...
