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

Pros
For the migration process from the older VMAX arrays to PowerMax, we VMotioned everything. It was easy.The stability is great. It is five nines.It has reduced our footprint in different physical locations.The number one most valuable feature is reliability. I want to go home at the end of the day and come in the next day knowing it works, especially since we have storage offshore.We were able to move away from a middleware solution for high availability, going right to snapshots and data replication on arrays.We use ESRS for our call-home, and a lot of times, Dell EMC will respond to the issue before we even know it.The response time, compared to XtremIO, is far better.It is a true, stable product.

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.

Cons
The initial setup was complex, and we had experienced people working on it.The initial setup was complex, as it is a complex system and you have to learn a lot.Setting up PowerMax with VMAX is always complex.I would like to see the rack change. They have defaulted to the standard rack, so our fiber cables are crowded when we shut our back door.We have issues that we don't know about, which Dell EMC fixes.I would also like to see a real-time, graphical view of metrics. I don't know how far back in time we can look, but if we could see the performance from two months or three months back, and how it is performing now, that would be helpful.The initial setup was a little bit complicated.The NVMe integration could be improved.

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.

Pricing and Cost Advice
From a general capital investment, it's one of the higher price points in the market. It depends on the size and software features that you would include in a system. So, the cost varies dramatically.The cost has room for improvement.It scales enormously, but it's expensive to do so.The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive.Our costs are on a yearly basis.Our costs for the product are three million.From reclaiming data center space which is so tightly constrained these days, it will pay for itself in a short amount of time, which is fantastic. Anything we can do to get more out of our current physical data center space helps us a ton, and PowerMax has helped enable that.

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.

The PowerMax NVMe is the high-end storage fromDellEMC it can provide up to 10M IOPS, however, if you need less, you can go with the new Unity XT which is going to have NVMe as well.

The new Unity XT is going to be ready for order in June 2019.

I have used all, EMC, and HPE 3Par, VNX, Unity, etc. All are OK. But for long term Flash Storage, I would take a look at Hitachi F Series. Best reliability hands down and they provide non-disruptive migrations, no server downtime, no scheduling with users, etc. NDM makes Hitachi a no brainer.

Does PowerMax have storage virtualization for external storage as part of the package?
