Building a NASBackground. Ive been fascinated by high volume, fault tolerant data storage systems for a long time. I started my data storage setup in earnest with a 4 disk RAID 5 array on an ARC 1. Windows desktop. When that array inevitably filled up, I added another array on a second ARC 1. That slowly filled up, too, and I knew I couldnt just keep stuffing RAID cards in my desktop I had to build a serious file storage server eventually. Mosh mobile shell Remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user. Bonjour, Je narrive pas me connecter en ssh avec raspbmc. Jai install liso sur la carte sd 2jai dmarr mon raspberry 3j. I considered many different storage options and configurations, including a large hardware controlled RAID system on a Windows or Linux environment, a software controlled array in a Windows based server, a Drobo type keep it simple, stupid system, and continuing to simply add more drives to my desktop computer. None of these options seemed to address all my requirements very well. I eventually stumbled upon Free. NAS, a Free. BSD based, network storage oriented operating system that uses the ZFS file system and a web interface to configure network sharing and other settings. While most of the setup and system management is done through this web interface, but you can extend the machines capabilities quite a bit through the terminal via SSH. In this article, Ill go over my hardware selections, the build and configuration process, some of the other applications I have running on the machine, and a bit of theory about how ZFS allocates array storage space and how it can be tuned to reduce allocation overhead. I want to make a quick note before diving into this excessively long article. I started writing the first few sections intending to create a detailed build log for my server. I took pictures and documented every step as well as I could I had been planning this server over the span of several years, so I was understandably excited to get into it. As the article progressed, it started to shift into a combination of a build log and a tutorial. While the exact set of parts and the sequence of their assembly and configuration will likely be fairly unique to the machine I built, I hope that people undertaking a similar project will find helpful information in some portion of this article. My contact information is at the bottom of this article if you would like to get in touch with me for any reason. Contents System Summary.

Ive been fascinated by highvolume, faulttolerant data storage systems for a long time. I started my data storage setup in earnest with a 4disk RAID. TB of usable space. The drives are connected to 2x IBM M1. How To Install Irssi On Ubuntu Iso FileI re flashed to run in IT mode. The boot volume is stored on 2x mirrored Intel 5. GB SSDs. The server is housed in a Super. Micro SC8. 46 chassis with two 9. W redundant PSUs. The system is built on a Super. Micro X1. 0SRL F LGA2. Im using an Intel Xeon E5 1. CPU 4 cores8 threads 3. GHz and 4 modules of 1. GB DDR4 Samsung ECCregistered memory for a total of 6. GB of RAM. Im using a Noctua cooler on the CPU and I replaced the noisy stock chassis fans with quieter Noctua fans. I got an APC 1. 50. VA Smart UPS and stuck both it and the file server in a Lack. Rack Enterprise Edition. I set my primary dataset with recordsize 1. Mi. B to account for data block placement in an 8 drive Z2 array. All the data is shared via SMBCIFS. The system hosts several different Debian based bhyve VMs to run various services I use on a day to day basis including nginx, pi hole, irssi, an Open. VPN server, and an rclone client I use to back up my data to the cloud. I have scripts set up to send SMART and zpool status reports to my email address on a weekly basis and scrubsSMART checks scheduled every 2 weeks. I also have a script that automatically adjust the chassis fan speeds based on live HDD and CPU temps. Of course the primary purpose of the NAS is data storage. The vast majority of the data I store is from the high resolution photography and videography Ive done over the past 1. I could probably go through and delete about 9. I would rather keep everything around so I can pretend that maybe some day, someone will be interested in looking at them maybe Ill have very patient kids. I look at this use case as a modern version of the boxes full photo albums and slides my parents and grandparents kept in their basement for decades and never looked at. Even if no one ever looks at my pictures and videos, its still be a really fun project to work on. By the way, if youre interested in looking at some of my favorite photographs, you can find them here Photos. The server is on the top shelf with the UPS on the bottom. A view from the side. The network equipment on top of the table is also connected to the UPS. The other computer on the left my main desktop is not on the UPS. A shot of the inside of the system. Another view of the inside of the system. Note the strip of wood tied to the top of the HDD fan wall. This is to prevent air from flowing back over the top of the wall, thus cutting the flow through the drives. Here is a screenshot of the mounted share. The Free. NAS devs recommend not going under 2.

Be able to saturate a gigabit ethernet line on SMBCIFSHave a quiet enough system that it can sit next to me in my office. Redundancy and overall system stability were also obvious objectives and led me to select server grade components wherever appropriate. Heres a breakdown of the reasoning behind each part I selected Chassis Super. Micro SC8. 46 I purchased this used on e. Bay for 2. 00 shipped. It retails for close to 1. I considered the Norco RPC 4. Super. Micro chassis is much higher quality and has better thermal design i. HDD sleds for better airflow. The specific chassis I purchased came with an older version of the SC8. I had to buy a different backplane. The PSUs the chassis came with are really loud, so I purchased some quieter ones. The stock system fans are also loud, so I replaced those too. More information on the replacement backplane, PSUs, and fans below. I currently have 8 open drive bays to allow for future expansion. Motherboard Super. Micro X1. 0SRL F This is Super. Micros basic LGA2. An LGA1. 15. 1 based board would have worked but the SC8. ATX boards and the full ATX versions of Super. Micros LGA1. 15. ATX mounting holes, so I could have saved a fair bit of coin there. Oh well. thanks utechmattr on reddit for pointing this out. LGA2. 01. 1 will also allow me to add more RAM if I ever need to.
