Every now and then I get the urge to build a new NAS and this year is no different.  With a bunch of old parts to recycle I wanted to create a low-power, high-capacity and fast NAS for backing my virtual machines over iSCSI.  To make it more interesting I am going to run the entire NAS as a virtual machine.  For full step-by-step instructions check out the blog post at https://guyrobottv.wordpress.com/2017....  You can check out the parts used in this build over at http://bit.ly/2i6bTCu.

★ The Annual NAS Challenge ★
For some reason I like to build large storage arrays.  I do tend to eat up a lot of storage and over time I’ve filled them up.  For the last couple of years I’ve gone big and in 2016 I decided to just buy an off the shelf Drobo 5N filled with 5x 4TB SATA drives.  It’s fine but there have been a few issues with it – the lack of active directory integration means I cannot securely use it to store virtual machine disk images for Hyper V Server and a lack of iSCSI and slightly lack-lustre out the box NFS implementation has left me with the same problem for VMWare ESXi virtual machines.  I’ve ended up just using it to store all my old backups and ISOs but don’t feel I’m getting the most out of it.

I had some old parts sat around that I shared on Facebook a while ago – motherboards, CPUs, RAM and a lot of disks.  Amongst them were 4x 4TB matched SAS drives and a SAS HBA I had used on a project a couple of years ago.  At that time I was working on a NAS that I never quite felt happy with and then personal issues meant I had to leave it in an undesired state.  Most of it got torn down but a few bits remained so this year is mostly a rebuild of a NAS from the past but with a clear intention on stability and performance – at least matching my Drobo 5N when it comes to network speed.

The last NAS had a number of issues:
1. Trying to get everything in to a 2U case proved extremely loud and messy
2. Consumer grade hardware posed issues with OpenIndiana, switched to FreeBSD
3. iSCSI stability issues – regularly lag spikes
4. Speed never ended up particularly high
5. Significant management overhead just to keep it running

I did however really enjoy working with ZFS and found iSCSI worked wonderfully for my virtualization needs.  With a focus on backing virtual machines for my projects and learning from this build in the past this year’s requirements are:
• iSCSI protocol
• SMB with Active Directory integration
• At least 100MBps sustained speed for an iSCSI read or write operation
• Potential for link aggregation
• ZFS implementation
• Rapidly upgradeable NAS operating system
• Low management overhead
• Needs to look good and remain quiet on my desk as this won’t be in a data centre or rack mounted in my garage
