NAS aka Network Attached storage devices help to overcome storage problems and gives your data a centralized place. A place where people can access and share the data 24×7 through the network. There are lots of companies that offer Software + Hardware NAS boxes which are basically an out-of-box NAS solution, for example, Qnap and Synology are two veteran NAS vendors.The cost of NAS boxes depends on the features such as the amount of storage, RAM, CPU etc. But if you want to convert your old system into a NAS box without spending hundreds of bucks then here is the solution. The Opensource Linux NAS software is light Linux Distros but enough power to handle your storage problem. You can build your own NAS server for your small business by using an old or new server/PC hardware. Here is a list of some best open source NAS Linux Operating system available on the Internet.You can use the NAS box along with some software like OwnCloud to create personal home cloud storage solution.
The personal cloud solution helps you to sync your personal files directly from the desktop to mobile devices. You can also listen to your songs and watch movies on the mobile phone those are stored on your NAS or personal desktop, while on the go using the internet connection. Here are 6 Best Free NAS Software: Linux BasedIf you don’t want to go through the whole article, then here is a quick view of the NAS operating system list. All are listed according to their popularity.
FreeNAS. NAS4Free / XigmaNAS. OpenMediaVault (OMV). Openfiler. Rockstor.
Nexenta Community Edition. Amahi. CryptoNASFreeNASFreeNAS is a most popular free and open-source NAS operating system that has enterprise-class features and enterprise-ready ZFS open source file system. It can be installed virtually as well as on hardware to create a centralized data environment.
The interface it provides is very intuitive (web interface). It supports Windows sharing SMB/CIFS, NFS and Apple file shares (AFP), FTP, iSCSI. Besides this, it also supports plugins to extend its functionally such as CouchPotato, SickBeard, SABnzbd, Maraschino, HTPC Manager, etc.One thing should be noticed before installing this OS on some Old specs system is that it needs a good amount of RAM to work, especially when you planning to install a ZFS file system.NAS4Free / XigmaNASNAS4Free is an Open Source Storage NAS (Network-Attached Storage) distribution based on FreeBSD.
Earlier it was known as NAS4Free but in 2018 its developer has renamed it to XigmaNAS. XigmaNAS supports sharing across Windows, Apple, and UNIX-like systems.It includes ZFS v5000, Software RAID (0,1,5), disk encryption, S.M.A.R.T / email reports etc. With the following protocols: CIFS/SMB (Samba), Active Directory Domain Controller (Samba), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, and BitTorrent which is all highly configurable by its WEB interface.It supports ZFS and encryption services.

.My latest Synology NAS server: the DS620slim. Dong Knows TechA while ago, somebody asked me about my most important piece of tech and was surprised when I said it was my Synology NAS server. But that’s true! Despite the not-so-sexy name, that NAS box is my most critical gadget.If you’re wondering what I’m talking about, this post is for you. And even if you know about network storage, chances are you’ll learn or thing or two. I’ll explain here, in layman’s terms, NAS in general, and the steps to get a server up and running.
And you’ll also find out why I picked Synology as my personal NAS choice — this is not a sponsored post. Table of Contents.What’s a NAS server?NAS is short for network-attached storage. A NAS server is similar to an, but it connects to a router (or a switch) via its network port.
And that makes a world of difference. NAS server vs. External driveAn external drive connects directly to a computer, likely via a USB or Thunderbolt port — it’s a direct-attached storage (DAS) device. For this reason, a DAS device, like the or, works only with one host computer at a time. Also, it generally just adds additional storage space and nothing else.A NAS server, on the other hand, is available to the entire network at all times, and it can deliver much more. Just like a real server, a NAS server can provide many services, such as serving content to streamers, hosting personal cloud storage or a backup destination, working as a mail server, running virtual machines, and a lot more — all at the same time. The possibility is endless.And as for storage, NAS servers can house multiple internal drives to host lots of storage space with redundancy.
So to understand a NAS server well, you need to know RAID. Redundancy (RAID) explainedIn data storage, redundancy is the use of extra disks (or drives) that are not strictly necessary to provide the storage space but to prepare for when a disk fails unexpectedly. You then have the option to fix that without losing any data or even having put your system offline.You get redundancy by using RAID, which is an acronym for redundant array of independent disks. Different types of RAIDs have different levels of performance and resiliency — the tolerance against drive failures — but they all depend on how much storage you’re willing to sacrifice.
With six drive bay, the Synology DS1618+ offers a wide range of RAID options. Dong Knows Tech Standard (classic/conventional) RAID setupsAs the name suggests, with RAID, you can lump a bunch of disks together into a single storage entity.
Depending on the number of disks in use, you have the following popular standard RAID setups.RAID 0: Also known as disk-striping, RAID 0 is when you combine two (or more) disks into a single volume. This volume has the storage space of all involved disks’ combined capacity. For example, if you use two 2TB drives in RAID 0, you’ll get a 4TB volume. RAID 0 delivers fast performance since it writes one copy of data to multiple disks — each disk only needs to hold a portion of the data. In return, RAID 0 has no data protection.
If one of the drives fails, the RAID is dead — you’ll lose data on all disks with no chance of recovery it in full. It’s the only non-redundancy RAID.RAID 1: Also known as disk-mirroring, RAID 1 is the opposite of RAID 0. It combines two drives into a single volume with the capacity of just one drive. Again, if you use two 2TB drives in RAID 1, you’ll still get a 2TB capacity. For this reason, your data survive if one of the two disks fails. In return, RAID 1’s performance is slow since it has to write two copies of data to two physical disks.RAID 5: This RAID setup requires three or more drives. It uses one drive as redundancy, so it has the capacity of all involved drives minus one.
For example, if you use three 2TB drives, you’ll get 4TB protected storage space; five drives will return 8TB, and so on. RAID 5 delivers capacity, redundancy, and performance, but it favors performance over redundancy. In a RAID 5 setup, your data is safe when one of the involved drives fails.RAID 6: This RAID setup is similar to RAID 5, but it requires four or more drives and cares more about redundancy by setting aside two drives for data protection. That said, in a RAID 6, your data survives even if two drives fail at the same time.RAID 10: This one is a popular nested RAID setup, which is a combination of RAID 1 and RAID 0. It requires four drives.
RAID 10 delivers both performance and data protection. RAID 10 has 100% data safety against one drive failure and a 50% chance against the case when two drives fail at the same time.When a drive in a redundancy RAID fails, the RAID is now “degraded.” The storage device will give you a notification, via indicator lights or beeps. When this happens, you need to replace the failed drive for the RAID to rebuild itself.
The rebuild process can take a long time — hours or even days — depending on the amount of data the RAID stores. But during this time, you can still use the device, just at a slightly slower performance.
Standard RAID requirements and drawbacksAll standard RAID setups require drives of the same capacity. You can mix drives of different sizes, but then all of them will deliver the same amount of storage as the lowest-capacity one. For example, if you use a 1TB, a 2TB, and a 3TB together, all of them will be regarded as 1TB drives — you have access to a total of just 3TB of raw storage space, and not 6TB.
In other words, you’ll waste the surplus storage spaces on the higher-capacity drives. You waste a lot of storage space when mixing drives of different capacities in a standard RAID. SynologyAlso, in a standard RAID, there’s no way to scale up the storage space. If you want to change the RAID’s capacity, you’ll have to follow these steps:. Back up the RAID’s data to another device. Rebuild the RAID from scratch with higher capacities drives. Restore the data from the backup.Among other things, the whole process is quite time-consuming.
This shortcoming of standard RAID is where Synology comes into play. Synology Hybrid RAIDOther than supporting all classic RAIDs, Synology NAS servers also uniquely feature a proprietary RAID setup called Synology Hybrid RAID (SHR).SHR is an automated storage management system that, at its core, is similar to standard RAIDs. For example, when you use two drives, SHR works like RAID 1; with three or more disks, SHR is now identical to RAID 5.
When you have four or more drives, you have the option of using SHR-2 which is similar to RAID 6. Synology Hybrid RAID allows for mixing drives of different capacities without wasting any storage space.
SynologyHowever, SHR has one significant difference: It supports drives of different capacities. And this means two important things:. You won’t waste storage space when mixing drives of various capacities. You can conveniently scale up a server’s storage space without having to rebuild the RAID from scratch, by replacing the RAID with larger drives, one by one.By default, SHR always uses one drive for redundancy. However, if you have four drives or more, you can choose to use SHR-2, which reserves two drives for redundancy similar to RAID 6.I’ve used SHR for years and loved it. It delivers excellent performance — almost the same as standard RAID — and is very resilient in terms of data safety.
For example, SHR can often overcome the case when more than one drive fails at the same time. It’s almost always the case if you haven’t filled the RAID with more data than the surviving discs can hold. Why Synology?SHR alone makes Synology servers superior to those from other vendors. But this flexible RAID setup is just one of many things that make Synology NAS so great.It’s important to note that Synology is not the only NAS vendor you should consider.
There are many other NAS makers, and I’ve had the opportunity to work with servers from virtually all of them. For basic network storage needs, most, if not all, NAS servers will deliver. Some are also easier to use and more affordable than those from Synology.But if you want to get the most out of network storage, definitely pick a Synology.
Synology DS1019+: A DiskStation that can hold up to 10 internal drives, is released in 2019 and belongs to the Plus series. Dong Knows Tech Synology’s NAS naming conventionSynology NAS servers come in different tier and models, based on the number of drives they can house, the hardware specs, and the release year. You’ll see names like DS1618+, RS1619xs, FS1018, and so on.
It’s a good idea to know what those names mean.There are three parts in the names, the leading letters, the numbers, and the ending letter(s)/characters. Here’s the breakdown of how to interpret them: The leading letters in a Synology NAS server’s nameThis part has two or three letters that show the types of the server:. DS stands for DiskStation: A desktop design with drives installed vertically. Within the web page, the Synology DSM behaves like that of a conventional desktop operating system. Synology NAS server: State-of-the-art operating systemAll Synology NAS servers run the company’s Linux-based DiskStatin Manager (DSM) operating system — currently at its 6th revision. For this reason, no matter which model you get, you’ll have the same core experience. DSM is where the power of Synology NAS servers lies.
It’s by far the most advanced and robust NAS OS.You access this OS via its web-interface — the way you do — but within the web page, DSM behaves like any other desktop OS. It has a start button, a desktop, a taskbar, and a control panel.
When working with it, you can open and rearrange multiple windows, log in, and log out as different users, etc., all with transitional effects.In all, working with a Synology NAS server is similar to doing a real Windows or Mac computer. DMS is robust and has excellent text-based help and description. If you’re tech-savvy, you can figure things out quite quickly.What’s most important is that DSM is consistent throughout the entire Synology ecosystem. As a result, once you know one Synology server, for the most part, you know them all. Again, it’s just like any Windows or Mac OS. The support for the Windows Server domain makes Synology NAS a great business storage server.
Dong Knows Tech Synology DSM’s useful core settings and featuresLike all OSes, DSM has all the essential functions, such as user management, network settings, security, shared folders, and many others.It also has the following, which makes Synology servers so powerful right out of the box:. Package center: An app store where you can install more applications that add features and functionalities to the server. Right now, Synology offers more than 100 and counting free, high-quality apps, and you can also manually install apps from third-party developers. QuickConnect: An easy and quick way to use your server remotely. All you need to do is register a unique name; after that, you can access your NAS from anywhere, on a computer or a mobile device, or by going to UniqueName.quickconnect.to. By the way, if you don’t want to have an account with Synology, you can skip QuickConnect and use.
Mobile apps: Many Synology NAS applications have mobile versions. That plus the QuickConnect feature means you can use your smartphone or tablet to access your server from anywhere — for example, stream content stored on the server, or monitor your home security via the surveillance app. Advanced storage and user management: Support all standard RAID as well as SHR, a Synology server delivers all the storage setup you’d want, from the most basic to the most advanced levels. You can also set up storage quotas for each shared folders and conveniently manage permission down to an individual sub-folder. Active Directory integration: This is a powerful business feature that allows the NAS server to be part of a network with a Windows Server domain controller.
