FreeNAS in Production

Written by Annie Zhang on .

I work as a Network Administrator in a shop where we deploy 60+ ESXi VMs on a half dozen host servers.  We heard about FreeNAS from my predecessor who implemented it where he is now employed.  My boss asked me to evaluate FreeNAS as it is time to replace one of our existing SANs.  I installed FreeNAS 9.3 on an old IBM server and took the four 3-hour FreeNAS classes from Linda Kateley. I then dove in head first with a new 4U SuperMicro SAN with dual Intel CPUs, 128GB EEC RAM, twenty 4TB SAS HDDs and a handful of consumer grade SSDs.  The important lessons learned are:

  1. Buy big RAM chips so you have available slots if you need more RAM.
  2. eMLC SSDs cost more but they are definitely better than off the shelf SSDs.
  3. There is a 4X & 5X FreeNAS rule that states you want 4 or 5 times as many gigabytes of SSD capacity for cache as you have gigabytes of RAM.  I always go big so we deployed the 8X rule.
  4. Download FreeNAS and install it on a test platform and then take Linda Kateley’s four paid and one free interactive online class to get started.  The FreeNAS forum is wonderful as long as you research your questions before posting.
  5. RAID cards are not needed but if you want an LSI RAID card make sure you flash it to IT (pass through mode).  LSI support & the FreeNAS forum were great in guiding me to the correct utilities I needed for my LSI SAS 9211-8i Host Bus Adapter.
  6. If you want the lights to work correctly on the front of a SuperMicro SAN use only SAS HDDs.

A very knowledgeable admin on the FreeNAS forum sent me a quote that is quite appropriate:  “It’s like a learning cliff.  We know.”  That said, Linda’s class made it much more like a steep hill and very manageable.
Currently I have the fastest SAN I have ever had the pleasure of working with and all the hard work pays off when you see you have maxed out your state of the art fiber gigabit network.

We’re Expanding!

Written by Annie Zhang on .

As you may know, last year saw an increase in demand for our storage and server products and that demand continues to grow. When we started out, we were just a small group of close-knit people. Over the years, we steadily added more and more talent to our company and before we knew it, we had grown to over 100 employees.

Of course, with that growth comes challenges. To put it simply, we don’t have enough space for employees to sit.

We had this problem about a year ago, so we renovated the software engineering area to add more desks. But here we are, out of space again. Some suggested using a double-tiered desk, but clearer heads prevailed with the solution of acquiring a second building.


Meet our second office. It will be the new home of FreeNAS as well as house TrueNAS software engineering and support. It’s down the same road from our current office. We’re not moving, just expanding. The iXsystems headquarters office is unchanged, as is our contact information.

The obvious benefit of this expansion is that people will have their own work spaces again and as we hire new employees, they will have a place to sit. The expansion will also allow us to cluster departments together.

It will be finished shortly. We expect to finish it in the next few months. When we’re all settled in, we’ll let you know, so feel free to drop by and check it out.

Hello FreeNAS Users,

This time DCIG ranked both our TrueNAS Z20 and Z30 arrays “Excellent” and “Best-in-Class” in hardware in the newest guide in their series, the “Midsize Enterprise Hybrid Storage Buyer’s Guide”, putting it ahead of competitive offerings from EMC, Hitachi, HP, Dell EqualLogic, Nimble Storage, Fujitsu, and others.
Also by popular request, we have a guide for running FreeNAS as a VM and a tutorial demonstrating the setup wizard introduced in FreeNAS 9.3.
