Vincenzo D'Aniello

Software developer at TREXON S.R.L.

Open-source with great disk management and task synchronization

The system itself allows you to add any feature. The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult. For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded. If you find the documentation, it is always incomplete and fragmented.

Offers high performance and dependable support for fast storage needs

The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution has been very stable so far."

"The ease of use of the 'jail', the management of backups, and copies to easily create test and pre-production scenarios have speeded up the development and distribution of business apps."

"The stability is quite good; our system is in production and we have not had any problems with it, and when a drive fails, we don't really have any disruption because we can easily rebuild the disk, even if it is very large."

"FreeNAS is much simpler and easier to use than other solutions, but we don't have the complete range of features that come with the full version."

"The fact that no data are lost when a hard drive fails is extremely reassuring, as I have had two of five drives fail at one time and no data were lost."

"It integrates well into either Windows or Linux environments."

"What I like about it is that I can work on it from any computer or any device. The initial setup is very simple. The setup wizard is really helpful."

"After using FreeNAS I will never spend money for commercial products like Dell or 3Par."

More FreeNAS pros

"IBM FlashSystem is a stable solution."

"I would advise colleagues to use FlashSystems."

"After we migrated them under the IBM Flash Array, the overall IOPS rate has increased by 30% and its latency is lower."

"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."

"The most valuable feature is that is supports a high IOPS rate."

"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."

"IBM FlashSystem has been stable in our operations."

"The initial customer technical support was efficient and effective."

More IBM FlashSystem pros

Cons

"FreeNAS should be better prepared for clustering."

"One of my hard drives has failed and the documentation that I've been able to find has not helped."

"They can improve the integration with PSA systems. This functionality could be better."

"They should include clustering for the solution."

"Make it easier to find out how to fix things when something goes wrong."

"The latest version of the dashboard doesn't work as good as the previous version. Sometimes we change our dashboard back to the previous version because the latest version just doesn't work as good."

"The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files."

"Its support for Hyper-V clusters."

More FreeNAS cons

"We think that IBM has to continue to invest in additional data reduction capabilities which are on their roadmap."

"The initial setup is complex."

"Our model does not support compression or deduplication."

"It should increase sociability with respect to number of disk shelves and capacity."

"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."

"I don’t really have a feature that I’d be using."

"There is a need for more help with the commands because, from version to version, they change; so what I used to use back in the different version, I can't use now."

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

More IBM FlashSystem cons

Pricing and Cost Advice

"We use the free version of the program."

"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."

"Its licensing cost is based on the hardware capacity."

"Its price is okay. It suits our needs."

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

"The total storage capacity vs price is still quite high for the IBM Flash Array."

"The solution has good pricing, but it is not cheaper."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."

"I find the pricing of the solution to be very reasonable."

"You purchase it as a bundle and the price is comparable."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
