About this deal

To get exact numbers, I may possibly write up another blog post in the future when I can connect some SSDs to test the controllers max speed. At this time I don’t have any immediately available. I needed to create a Windows File Share for file based storage from Windows computers. I plan on using the Windows File Share for high-speed storage of files for video editing. This design was focused on creating non-redundant extremely fast storage. Because I’m limited to a total of 4 NVMe disks in this design, I chose not to use RaidZ and striped the data. If one NVMe drive is lost, all data is lost.

Later on in this guide, you’ll be copying the boot partition from the SD Card Linux image, on to this newly created boot SD Card for the NFS Root. Prep the Linux install for NFS Root If you want to just run your stuff right now, my recommendation would be a AMD Ryzen 5 5600 CPU coupled with a Gigabyte Aorus B550M Elite board.The current plan for the storage environment is for video editing, as well as VDI VM storage. This can and will change as the project progresses. The History The results were great, the performance was amazing, and both servers had access to the NFS export via 2 x 10Gb SFP+ networking. You’re now complete and have a fully working NFS root for your Raspberry Pi. You’ll no longer worry about storage, have high speed access to it, and you’ll have some new skills!

If you’re a regular reader you know that from my original plans ( post here), and than from my issues later with iSCSI ( post here), that I finally ultimately setup my Synology NAS to act as a NFS datastore. At the moment I use my HPE MSA 2040 SAN for my hot storage, and I use the Synology DS1813+ for cold storage. I’ve been running this way for a few years now. Why NFS? If you haven’t already configured an NFS export on the NAS, do so now. No further special configuration for v4.1 is required other than the norm. Press the Green “+” and you’ll see it spreads them to the “Servers to be added”, each server entry reflecting an IP on the NAS. (please note I made a typo on one of the IPs). While you could use this card with Windows software RAID, or Linux mdraid, we’ll be testing the card with FreeNAS, a NAS system built on FreeBSD.We all love the word multipathing, don’t we? As most of you iSCSI and virtualization people know, we want multipathing on everything. It provides redundancy as well as increased throughput. How do we turn on NFS Multipathing? After enabling this, I noticed that RAM and Memory usage had drastically increased on the Synology NAS. This would peak when my ESXi hosts would restart. This issue escalated to the NAS running out of memory (both physical and swap) and ultimately crashing.

In the future I plan on digging deeper in to optimization as I still see other services I may be able to trim down, after confirming they aren’t essential to the function of the NAS.With great suspense, the server powered on as per normal. No errors or health alerts were presented.

It’s now time to configure the sharing protocols that will be used. As mentioned before, I plan on deploying iSCSI, NFS, and Windows File Shares (SMB/Samba). iSCSI and NFS Configuration You can see that the read speed was impressive, but the write speed was not. This is partly due to how writes are handled with NFS exports.Since you’re pushing more data, more I/O, and at a faster pace, we need to optimize all layers of the solution as much as possible. To reduce overhead on the networking side of things, if possible, you should implement jumbo frames. There’s a few things we have to do to prep the Ubuntu or Raspbian Linux install to be usable as an NFS Root.
