nas36-angle-squareeRacks Open Source Systems announces the immediate availability of the eRacks/NAS36 rackmount storage server, with 36 removable 3.5″ hard drives, which yields a maximum of 144TB (Terabytes*) of raw storage with current widely-available technology. The eRacks/NAS36 rackmount server is shipped pre-configured to the user’s custom specs, with any available open-source software, and more flavors of Linux or BSD available than any other vendor.

Fremont, CA (PRWEB) February 14, 2014

eRacks Open Source Systems is pleased to announce theeRacks/NAS36 rackmount storage server.

Available immediately, it combines a rack usage of only 4U with a density of 36 drives (24 front and 12 rear), which, when combined with the current technology of widely available 4TB drives, yields a total storage of 144TB.

With the forthcoming 6TB drives from WD HGST, this will increase to 216 Terabytes*, giving a truly petascale solution in only 4U of rackspace.

This rounds out eRacks’ line of rackmount multi-drive storage servers and NAS solutions, nicely filling the gap between the 24-drive eRacks/NAS24 and the all-front-loading 50-drive eRacks/NAS50, eRacks’ flagship storage server.

When populated with 36 removable drives in only 4U, this represent a density / price breakthrough – using the best value (lowest price/TB) 3TB drives, this enables 108TB of raw storage in only 4U, and for less than $20,000, as configured on the eRacks website.

The unit is also available partially populated, at a reduced price, to make it accessible at a lower initial price, and the storage nas36-both can be increased later by filling the empty drive trays.

It’s signature service, eRacks will be happy to install any of the popular Linux distributions on request – Ubuntu, Debian, RedHat, Centos, Fedora, even the Arch Linux distro, which is growing fast in popularity, as well as FreeBSD, OpenBSD, or other Open Source OSes.

eRacks will also pre-install any open source NAS software, such as FreeNAS, OpenFiler, NAS4Free and OpenMediaVault, among others – and administrative dashboards and web GUIs are offered on most of these software choices.

Also available is best-of-breed Open Source software for BigData / Cloud storage, NAS, and networking – including Hadoop, MooseFS, CIFS, GlusterFS, etc – and eRacks is a partner with

In addition, the eRacks policy is to install any Linux/BSD distro or Open Source software on request – Contact eRacks today at info(at)eracks(dot)com to see how they can meet your needs.

*For the purposes of this press release, the term “Terabyte” is used to mean one trillion bytes – eRacks understands the issues about this, we are using the term as the disk drive and other industry manufacturers use it.

Setting up a server at home can be a rewarding experience. Not only does it make for an excellent experiment and learning experience, it also allows you access to your home network from anywhere in the world. You may be tempted to think that such a project would be time consuming and expensive, but actually the opposite is true. Today, the software required for running a server is relatively easy to configure. And, with open source software, a cheap computer and the right internet connection, you can be up and running with minimal cost.

A home server can be a very useful thing to have, and is a worthwhile project, if for no other reason, because it’s a good learning experience. KMF Technologies can provide the hardware you need to get the job done, and can also offer consulting services for difficult software configurations. If you decide to take the time to setup a server at home, you won’t be disappointed.

The possibilities are endless with a home server. With an HTTP server like Apache  or Lighttpd , you can host your own homepage, keep a remotely accessible calendar, share information with family, friends and co-workers or even experiment with your own custom web applications, with complete control over the software that supports them.

With SSH and/or FTP running on your server, you can gain access to files you have saved on your machine. What if you come to work and discover that you left an important Powerpoint presentation at home? No problem. If you have your desktop computer on the same network as your server, you can use Wake-On-Lan to power up your desktop, SSH to copy the file to your server and SSH or FTP to download it. Problem solved!

Today, with modern Linux distributions such as Ubuntu , installing and configuring server applications has never been easier. With default configurations that work mostly out of the box with minimal tweaking, you can have a machine up and running in minutes. In addition, no special hardware is required. If you have a spare computer with a NIC, you have a server.


The only issue that could be an obstacle is your internet connection. First and foremost, you’ll require a broadband connection such as DSL or cable. In addition, while not required, it’s a good idea to get a static IP address if you can, which is just a unique identifier assigned to your network on the
internet that doesn’t change. DSL Extreme, for example, offers affordable static IP solutions to residential customers. From there, you would register a domain name and point it to your IP address, or get a free subdomain if you preferred.

If you can’t find a static IP, however, all is not lost. Using a service like, you can get a free subdomain name that can be automatically updated via your home network every time your dynamic IP address changes.
