Dell Compellent (discontinued) vs. FreeNAS vs. TrueNAS

Dell Compellent has a decent portfolio of products for varying sizes of business. Their licensing model is suited for those not wanting total a la carte fare, and administration is intuitive as compared to other storage arrays. This combined with Co-Pilot support gives Dell a good presence in a vast number of scenarios where networked storage is required over a DAS solution. It's only fallback is its own NAS solution, which itself may be better suited to smaller environments

FreeNAS suited really well in managing our legacy systems and it handled all our network flows really well, less maintenance is required on our part. FreeNAS also gave the option to switch to TrueNAS for free as now its support is limited. The major issue that we faced was with the installation as it is really complex and required lots of time. Rest all is good and FreeNAS still works well on our systems.

We have many TrueNAS units deployed and they've served us well everywhere. Our most common use case is using it as storage backing for virtual machines. We have Proxmox talking to it, as well as having it acting as the hypervisor. We've never lost data with it, even when faced with multiple disk failures. We've also always found the performance to be robust and able to handle the needs of our clients. Our clients range from libraries, to medium sized enterprises and we've always been able to make it work, and work reliably.

• Block level RAID with data tiered based on how often those blocks are read or written.
• You can mix and match different ways of accessing the SAN, FC or ISCSI.
• They offer the ability to mix and match drive speeds and sizes within racks. This provides for larger, slower drives to store old data, while providing fast SSD storage for data that is constantly in use.

Incentivized

• The FreeNAS web interface is modern looking. It makes tasks like provisioning drives into raid volumes easy.
• The ZFS raid option allows you to add in an SSD as a cache drive to increase performance.

Incentivized

• iSCSI Datastores for virtualization.
• NFS store for unix storage or backups over networking.
• Very fast performance, sometimes outclassing SSD arrays even in NFS.
• The ZFS filesystem has given use much greater flexibility.
• Using their newer servers we could in theory scale to any height of required storage.

• Reliability. We had several times where VMFS luns would become corrupted and we'd have to move all VM's off to other storage
• Performance. 1g iSCSI performance was abysmal (although the unit we used was an older device)
• Management and Monitoring. Both management and monitoring are pretty primitive. We were never able to integrate monitoring into Nagios.

Incentivized

• Not good for beginners as it requires deep understanding of networking and storage.
• Most of the good and required features are not available in free version.

Incentivized

• more graphical interface to admin features like plugins, jails, list are well but a tiles aproach will be better
• allow bulk upload/download/update to Groups or user accounts from SMB shares.
• some script language template featured to create/config/change/delete storage pools /dataset or shares .

The software has been amazing. It has saved me a lot of headache in the past few years. Also, it's nice to knowing that if any of our current Synology devices were to die I can have an iSCSI system up and running very shortly. I didn't give a 10 score because I find their support to be rather slow and pedantic. They test many things when the answer is right in front of them. The compute sytem (not storage) we purchased from them came with pcie gen4 nvme's. They didn't work, but rather than believe me about the spec's in the motherboard manual saying the onboard was pcie3 ONLY they shipped me 2 replacements until I showed them an old pcie3 device worked just fine. The part that rather frustrated me was the machine was claimed to have been tested / burnt in. How can this be true if the server won't even boot up into the BIOS?

The software is fairly straight forward and if you mess up the network interfaces you can login locally at the console and fix any issues that you may have had with VLANS etc denying you network access. There was a little bit of annoying issues when setting up multiple network interface cards. Rather than keeping one interface setup with DHCP, when you add a second one with a new network it disables the first. Which makes it impossible to login again. However if you wait it will revert. I learned after works that you need to set up the network cards and then go back and setup the first one again and THEN test / apply. After that it was pretty good. The summary of the devices is very nice to. You get an accurate snapshot of how well your system is doing as soon as you login

This is not solely based on the support engineers themselves but more so that the logging and gotcha's that their array has. There have been multiple times where logs are pulled, but the folder is not large enough, and it crashes the array. Other times there are certain aspects that support either does not know of or isn't knowledgable about how to look at particular issues that could be causing problems.

There were some things that can be found by other users on forums and Google and some things that were not.

The support was responsive for opening cases. However I found solutions to simple problems took far too long. When we had a bad power supply and we had another with the exact same firmware version they should have sent replacement for both. We had to file another case for the other PSU that started dyeing the same week. They also had to do a lot of troubleshooting to replace the fans that were not behaving as they should. I'm not a home user. I know when certain things are failing and the silly hoops the jump through made it frustrating. However, once we finally got the problem identified we had parts shipped out via advance replacement which was nice.

The implementation went well after we got the boot drive working properly. The device was setup exactly as i asked with the hardware except for the boot drive. The reason I chose 9 instead of 10 was the boot drive put us back about a week for the part to arrive. I ended up using a personal drive to show them that they were wrong sending use the gen4 drives.

I have used Dell EMC Unity XT and I will say that the SC Series is better in the areas of the scalability is excellent. If I need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself. In addition, I like the way it integrates with our environment. These features help us use multiple soft applications. They give us an advantage versus traditional storage resources.

Before swapping to FreeNAS, we'd been using plan old Linux servers running Samba and NFS with ZFS storage underneath. This worked really well for our requirements at the time but required a lot of administration when new versions came along, or new users had to be added or drives needed replacing, and so on. FreeNAS did away with 95% of that work and does a much better job too.

I chose TrueNAS (upgrading from FreeNAS) because of the small footprint, ease of use, and reliability of the ZFS file system. The file sharing protocols supported as well as the intuitive interface all make TrueNAS a great choice for business and hobbyists alike.

• This storage array is a middle-range array that brings speed with peace of mind due to the stability.
• The uptime has helped us with making sure the hosts and servers that connect to this array have as much uptime as possible.
• The negative still has to be that these arrays can't seem to handle quick/high I/O usage.

Incentivized

• Low-Cost Network Attached Storage
• Provides additional network storage to support client & business operations
• FreeNAS secures our data using custom encryption keys

Incentivized

• Using a TruNAS integrated solution has reduced support overhead compared to using custom hardware.
• Being cheaper than full flash storage arrays, this unit allows for a good balance of speed with its use of SSD-based caching drives.
• The reliability of the hardware/software integration means I spend less time troubleshooting and more time doing business. Coming from a custom-built solution it is apparent that IX Systems has done some extensive testing.
