For this we are actually using a small Supermicro barebones that is in our Fremont colocation facility. In terms of SSDs – the Seagate 600 Pro 240GB and 480GB drives are absolute favorites. You can get away without using the Intel DC S3500 however it is nice to be able to migrate from ZFS to the Ceph storage cluster easily. It should be noted that running FreeNAS or other ZFS storage in a VM is far from a leading practice, and there are many reasons why you would not do this in a production cluster. Moving over to the FreeNAS web interface, we can see these two drives are found in FreeNAS and ready for use. Without doing any further optimization like jumbo frames or multipathing, my N40L with 5 WD Red 3TB drives in RAIDZ could achieve the following results.
I actually had my N40L with ESXi, and then had a VM openindiana presenting the disks (raw disk). Enter your email address to subscribe to this blog and receive notifications of new posts by email. Several free and open-source operating systems run extremely well on a wide array of older hardware.
Ideally, FreeNAS should be installed on a small SSD or even a flash drive (though standard hard drives also work fine in a pinch), and the system should feature one or more reliable hard drives for bulk storage. When using the UFS (Unix File System), FreeNAS doesna€™t require much memory or processing power. The more advanced ZFS (Zettabyte File System) is highly reliable and offers an array of features to preserve and protect data, but it also has much more overhead. To set up FreeNAS youa€™ll need to download the installation ISO file from the FreeNAS website. Installing the OS to a flash drive is handier, and it frees your actual hard drives to store your files. If you dona€™t have an optical drive available, FreeNAS can be installed directly to a USB thumb drive (or other drive) using a couple of free utilities, such as WinRAR.
Next, insert your flash drive, run Win32 Disk Imager, and select the FreeNAS_x64.img image file. When FreeNAS initially boots, youa€™ll be presented with a simple text menu with 11 options. After booting to the flash drive, youa€™ll ultimately see a simple text menu with 11 options. The first time you hit the FreeNAS IP address, youa€™ll be prompted to set an administrator password.
Youa€™ll have to follow a few steps to configure your storage volumes and make them accessible to other systems on the network.
Which drives to use, the preferred file system, permissions and share names need to be configured before you can access the storage volumes on your FreeNAS server.
Youa€™ll also need to select the file system, enable any services or protocols of choice, create and name a shared folder, and set folder permissions. PCWorld helps you navigate the PC ecosystem to find the products you want and the advice you need to get the job done.
While shared storage isna€™t a requirement, ita€™s a best practice for VMware ESXi infrastructures of all sizes.

Once a physical server goes down, the virtual machine (VM) files that reside on that server become unavailable as well.
FreeNAS is a small shared-storage tool that's based on network-attached storage (NAS) technology. Because FreeNAS is based on a file-sharing protocol, there is some overhead when writing packets to the shared storage.
If you've ever worked with SAN products from NetApp Inc., you'll notice similarities to the Openfiler interface, which has a comparable look and feel.


Figure 2 Openfiler offers a complete iSCSI SAN that's configured easily from a Web interface.
For more granular storage--provisioning options, such as the ability to configure shared storage for client nodes, use the Openfiler Web interface. FreeNAS offers a Unix-based configuration for access to files, and Openfiler offers a Linux-based approach to access block devices. Before the virtual storage area network, there were Fibre Channel storage area networks and iSCSI. Leave on good terms from your system administrator job to avoid burning bridges and to keep a good reputation in the industry. We run our hardware very hard and in this particular chassis we have had issues with NVMe drives running very hot under heavy load. We are using ZFS on Linux for our boot device. As a result, we do have extremely easy access to adding ZFS storage in the native Debian OS. Just as a fun note, this particular installation was over the ZFS network drive shown in the example above yet everything went smoothly. We have shown examples running the 2GB FreeNAS base volume both on local and network storage.
If you have Proxmox VE you already have several advanced storage options to choose from including: LVM, ZFS on Linux, Ceph and GlusterFS.
For his day job, Patrick is a management consultant focused in the technology industry and has worked with numerous large hardware and storage vendors in the Silicon Valley. From that point you can create your shares to use it as Fileserver or shared storage for ESXi. If you do so, be aware that if your storage crashes while data is cached but not written to the disk you will end up with corrupt data.
One in particular, FreeNAS, is extremely stable, easy to set up, and laser-focused on storing and sharing files across your home network.A All you need is a working system with a reliable hard drive (or three) and a little time to configure everything. If you have an optical drive, burn that ISO to a disc and then boot from it the way you would any other bootable CD. You'll wind up with an image file named FreeNAS_x64.img, which youa€™ll need to write to the flash drive to install the OS and make the drive bootable. The entire image is only 1.86GB, though it requires a drive with a capacity of at least 4GB to boot and run reliably. In the Device drop-down menu on the right, make sure your flash drivea€™s drive letter is selected. Note, however, that the default user name is not "admin" or "administrator," but "root," which is the Unix system's rough equivalent of a Windows admin.
With shared storage, however, another ESXi host can access and start the VMs that were running on a failed server. There are two, free ways to that create a shared-storage infrastructure for VMware ESXi: FreeNAS and Openfiler.
After you install FreeNAS software, you have to configure the FreeNAS server's IP address before logging into the Web interface, which is used to set up and manage the shared storage. Openfiler offers real SAN functionality, which means you'll receive performance benefits from giving remote machines access to block devices and not to file systems. From here, you can easily set up the shared storage as either a SAN (shared devices) or NAS (shared file systems). If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. There are several projects to turn an old PC into a firewall appliance, FreeNAS turns an old (or not so old) computer into a Network Attached Storage (NAS) device. Plug in a decent sized USB hard drive and you can keep all your media (or business) files in one place. When run from CD it can store its settings on a USB or floppy drive, making it even more secure because the programs cannot be corrupted by a hacker.
While the VMware ESXi all-in-one using either FreeNAS or OmniOS + Napp-it has been extremely popular, KVM and containers are where the heavy investment is at right now. The goal of STH is simply to help users find some information about basic server building blocks. Today it is still a great system to be used with ESXi but there are better alternatives, especially due to its limited memory and CPU power.


You can also use the WD Velociraptor model which is a little bit faster, but much more expensive. You can also build somting like VSA on it (Running FreeNAS as Virtual Machine with RDM, presenting the storage back to the ESXi).
Assuming that's how your network is set up, it shouldA acquire an IP address and list it right at the bottom of the menu. You can access your FreeNAS server just like any other shared PC on your network (typically via Windows' Network settings).
The included iSCSI target is fast, which makes Openfiler a favorite choice for a free shared-storage arrangement.
But both tools install easily and allow multiple ESXi hosts to access virtual machines in a shared-storage arrangement. With many households having more than one computer now, keeping files on each computer is wasteful of storage space and frustrating because the file you need is always on "the other computer". FreeNAS supports most network file access protocols: CIFS (Windows file sharing, formerly SMB), FTP, NFS, TFTP, Rsync and Unison to mention a few. The Intel DC S3500’s will eventually be utilized as independent Ceph storage devices. We can then do fun things with the base FreeNAS VM image like move it to Ceph cluster storage.
Again, it would be much better to simply create a zpool with the two WD Red drives in the base Debian OS then create an iSCSI target to access the drives. And for those wondering, yes, you can simply add a Ceph disk to FreeNAS in this configuration and use FreeNAS to store information on your Ceph cluster. That was the reason why I rededicated my N40L to be central storage and file server with FreeNAS.
So, I don’t know if was just coincidence, or what to think about the same issue 2 times in 24 hours in the same USB port? The FreeNAS website has an extensive FAQ and community sectionA  that's definitely worth checking out. FreeNAS is based on network file-sharing protocols, and you can choose from Network File System (NFS), Windows' Common Internet File System or the Apple Filing Protocol.
The support for rsync and Unison means you can also use your NAS as a backup device, especially useful for a laptop where you need local copies for when you take the laptop out but need copies back at base in case it gets lost, dropped or stolen and you don't bring it back. If you do need to administer it, FreeNAS has a web interface that you can access from any other computer on your network. While we wish Proxmox made the jump and supported Docker native, LXC is at least a positive step. Should the mirrored rpool in the Proxmox VE cluster fail, we should be able to attach the two WD Red drives to another Ceph node and then pass-through the drives again to get our FreeNAS VM up and running. Again, this is just for experimentation purposes only and I would highly advise only trying that on a 10Gb network with at least 12 SSDs or 30+ hard drives in the Ceph cluster. This post describes what you need to use the N40L as resilient storage and how to configure it properly for ESXi usage. Insert the flash drive into the machine you want to use with FreeNAS, boot to the drive, and the OS should launch.
Command-line jockeys can configure many options right from the text menu, but ita€™s definitely easier and more intuitive to log into the web GUI.
Keeping shared files on one computer and sharing them over the network makes sense, but leaving a powerful, and power hungry, desktop computer turned on just to make some files available is hardly green, or economic sense.
FreeNAS has several other useful features, such as support for RAID and encryption, both giving improved security to your data in different ways and monitoring of your disks' health with email alerts. For those wondering what an All-in-One configuration is, it is simply a hypervisor and shared storage (with inter-VM networking) built-in.
Today we are going to show the FreeNAS version of the All-in-One configuration with the Proxmox VE 4.0 environment.
