after Download you can update
- OmniOS to 151010 newest, see r151008 r151010
- napp-it to 0.9f1+ (napp-it menu about - update)

For OmniOS/OI/Solaris Express 11: download Oracle manuals for Solaris Express 11,  google them
or check (Express 11 - downloads are working, links refer to new Solaris 11))

Oracle Solaris Express 11 and its free fork OmniOS/OI are nearly identical beside encryption.

appliance 13a: initial release 2013, problem with e1000 on ESXi 5.5
appliance 13b: base napp-it config (install add-ons separately),  e1000 with tcp offload disabled
appliance 14a: full napp-it config, first release 2014 with all add-ons and services

Napp-in-One offers the most options and flexibility. Download ESXi 5.0U3, 5.1 or 5.5 free without RAM-Limit from  (ESXi is a ultra lightweight Hypervisor - think about  as a Super Deluxe Bios extension where you can run supported operating systems like BSD, OSX, Linux, Solaris or Windows side by side, each with best performance). You should own a modern mainboard with passthrough support (vt-d) to virtualize your NAS/SAN with similar  performance like a barebone setup or you can try a physical RDM (Raw Disk Mapping) setup.

Install the free ESXi 5.5 (or 5.1) edition. enble pass-through support in your mainboard bios and in ESXI. Download the zipped and preconfigured VM, unzip it and upload the VM folder via ESXi filebrowser to a local ESXi datastore.  Import the VM with a rightclick on the .vmx file within the folder. Add your SAS controller as a pci device via pass-through to your OmniOS SAN VM and boot  it up. It is ready to run with 5.1/5.5 vmware tools, two nics (e1000 and vmxnet3 in dhcp mode) and root pw unset. Run ifconfig at console to get current ip and manage via browser and http://ip:81.

In a larger ESXi environment, you can use several Napp-In-Ones where each ESXi use its own local highspeed ZFS SAN. No single point of failure and no SAN bottleneck. You can use Napp-In-One datastores locally or remotely and you can use combined VMmotion and storagemotion to move to another machine.

For end-users this is free even commercially. Resellers need a bundling license.
Please discuss problems at

ESXi 5.1 U1: stable
ESXi 5.5 initial: not stable
ESXi 5.5 U1

There is a bug with ESXi 5.5U1 regarding NFS stability; please update 5.5 -> 5.5 U1 and then the 5.5U1 NFS bugfix

Howto update ESXi:

ESXi 5.5 U2 seems stable

Option2: barebone setup

Use this method if you like your own setup, if you only need simple NAS/SAN config without advanced support for other operating systems or  if you need a dedicated highspeed NAS or SAN.

Download a bootup ISO of OmniOS, OpenIndiana or Solaris 11.1, burn it and install to a local Sata disk or fast USB stick (min 16GB,  prefer 30 GB, best are SSDs). Configure your network and install napp-it via online command

wget -O - | perl

After setup I suggest to clone the bootdisk to an external disk or an SMB/NFS share (can be your desktop) with clonezilla (from USB stick) or with the help of an 3,5" hardware Sata raid 1 enclosure.  If you care about uptime, do a ZFS boot mirror on two disks.  If you use a hardware raid-1 enclosure, I would use it with its hotplug capability to clone the bootdisk - not for regular raid-use as they are not as good as ZFS mirrors.

In case of problems, use the bootable backup disk or restore from image with clonezilla within minutes.

Option3: napp-it ToGo (napp-it on USB)

- Download ready to use samples

Napp to Go is a preconfigured ready to use installation of OmniOS + napp-it on USB sticks suitable for a special mainboard. You must plugin the stick  into the same USB slot that was used during installation.

Napp-it to Go is ideal for distribution, tests or deployment of napp-it You only need to download the image, clone or backup it with the
included Windows  USB imager to a fast 16 GB stick.  You can then bootup your NAS. It is ready to use in a dhcp environment or you must set ip manually.

Download von "napp-it to go Sample images"
. (Ready to use USB images, download, boot, run)

-Build your own USB/ napp-it ToGo setup (suggested as the samples are not always up to date)

- use a 32 GB Stick, best is a 30 GB Sata SSD in an USB enclosure
- do a regular setup
- disable ZFS property atime to reduce writes
- backup/clone the Stick with my USB cloner (or use clonezilla) for easy restore

I have tried to setup AFP with a new install on OmniOS 1008 and failed with afpd: fatal: open failed: No such file or directoryy.
My other config (OmniOS1006 with AFP installed and the updated to 1008 work)
