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

Pros
The All-Flash models are pretty fast for the vast majority of our remote workloads.We use replication for disaster recovery (DR), making our DR process much easier.It has reduced complexity.We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint.It has good performance.We can get almost real-time response times.The most valuable thing for our use case is the flexibility to have multiple-protocol support.It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about.

It is pretty much just plug and play. There is not that much to do with it. It is very easy to use.The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems.The predictive performance analytics is a very good feature, as our system is performing better than before.The stability and performance are the best things about the solution.Because of the encryption, we have different storage and the encryption can go over both.The predictive performance analytics are good.It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done.The solution has probably reduced my power use substantially.

Cons
We would like to see the concept of Storage Groups brought back to this product line.I haven't seen the roadmap for this solution.It is missing some features, like deduplication.Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication.I would like them to continue to build on the solution and expand on the functionality, like replication.We'd like to see a cheaper version of an all-flash array in that footprint.I would like to have secure mobile connectivity going forward. This would help me be more proactive.If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced.

I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier.The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier.There are a lot of things to improve.It goes at about 95 percent, so we have had some performance issues. It is hard to clear them.We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter.We have not seen a reduction in our TCO nor have we seen ROI.We haven't seen ROI yet.I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side.

Pricing and Cost Advice
Our CAPEX was close to $42,000 and operating costs are below $1000.Our costs are roughly $200,000 a year.The solution is extremely functional for the price that we pay for it. It is worth the investment.We purchased a five-year warranty.Compression is making a difference towards the amount of hardware that we need to purchase.The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes.It scales, but then you have to buy additional stuff.With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity.

I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it.We evaluated Oracle and Hitachi, but Pure Storage had the better pricing.The cost has room for improvement.Our Evergreen Storage subscription is supposed to be good when we go to upgrade.The cost has room for improvement.The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again.We have an Evergreen Storage subscription, which I think is a great feature.The licensing is $100,000.
