But what’s different about this compared to ZFS in FreeNAS, is that the non-parity data is not striped across all the remaining drives, it fills up the drives one-by-one (based on a high water allocation method). This means that if a drive in your array fails, you can rebuild the array using the parity information stored on that drive. The way it works is when you build your array, you nominate one or more of your drives as a parity drive. This basically means the OS sees the drives indvidually, rather than arrays abstracted by a hardware RAID card. You either need a dedicated HBA, or a RAID card flashed to IT mode to act as a HBA.
Unraid setup bridge software#
So Unraid works using software RAID, which means you do not need a hardware RAID card, in fact if you use one it won’t work. Although it’s proprietary software, the community looked great, and there were some people making some great stuff for the platform.It’s options over and above a basic NAS were incredible.In the scary eventuality of a dual drive failure, I would likely only lose the data on the one drive, rather than the whole array.It’s software RAID was just more flexible, I didn’t have to add drives in even groups all the same size, and I could dynamically expand the array as I need to.I tried both but quickly settled on Unraid for the following reasons: So I was forced to choose quickly between FreeNAS or Unraid for the OS on the box. Oh and it’s also got 6 3TB SAS Drives, 2 TB SATA Drives and 2 240GB SSDs. The ECC is really important when running this as a NAS. It’s got a Xeon L5630 (4C/8T) ( have I told you how much I love the X58 platform?) but will take 2 and 24GB of DDR3 ECC Registered RAM. It has the slightly annoying side-effect of blocking access to the hot-swap bays and the power button but it has IPMI onboard so I can easily power the thing up or down with an app on my phone. I made the housing from some threaded bar, and 2 lots of anguled aluminium. It is a LOT quieter.Īnd it seems to be working so far. Those things have 7000RPM fans which are super loud! So I decided rather than have some 80mm fans suck air from the inside, I’d have trio of Noctua 140mm fans blowing air directly into the system, over the drive bays and over the CPU and RAM. Try running something designed for a rack mount where you want to work. Seriously, buy one of the X58 HP Z-series workstations, they are super cheap and built like tanks.Īs well as my work laptop, which is a standard build.Īs you can see from the photo above, I am not running the 48 port switch at the moment (I got it for a steal) but it can be used at a later date, but you can see the 4 yellow uplink ports which are bonded together for bandwidth and redundancy. This thing is sick, it has 24 Logical Cores. HP Z800 (Dual Xeon X5675 - 6C/12T, 48GB RAM, GTX 980Ti) - for me, it’s what I am typing on now.In this room I also have 2 desktop PC’s (for me and the wife): Xerox Phaser 6125N Colour Laser Printer (sitting on top of the cabinet).HP ProCurve 2510G-48 Gibabit Managed Switch.HP ProCurve 2510G-24 Gigabit Managed Switch.Here the 4 cat-6 cabled enter another 18U cabinet which has: DHCP is handled by the router (I have 256 reserved static IP addresses, the rest are handled by DHCP) and I have 4 gigabit ports bonded together (in LACP) that run out the back of the cabinet, along the wall and up through the ceiling. This provides the connection for the mesh network (I have 3 other disks) into the router which provides the wifi for the house. Mikrotik RB2011RM Router (running RouterOS).So in this room (in a 9U low-profile cabinet I have the following): This is where the BT master socket is, and whilst not ideal this is what I have to work with. In my house I have the following setup: Dining Room/Play Room Our old setup was based around our needs in the our old house, but since we moved to a much larger house (with much thicker walls) I’ve had to sort out the networking and IT setup to better fit with our needs. I’ve recently been rebuilding our home IT setup. I’ve been using Unraid for my NAS, Backup and Media servers at home, and here is why it’s awesome.
