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

Pros
The optimization of the cache memory of each engine and the use of persistent memory.It is efficient and very simple for our administrators to use.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.

This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities.This solution makes it easy to manage storage, provision new workloads, and scale-up.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.

Cons
The main feature that I personally want to see is the possibility to upgrade to the next generation without changing all the components and just change the engine, relying on the compatibility matrices between two different generations. Meaning that we could just keep the enclosure and upgrade the engine, integrating the enclosure to the existing pool, then adding automation tools for orchestration.I would like NVMe to be end-to-end in the next release. Right now, it is not end-to-end.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.

This product needs to have better integration with enterprise backup solutions and archiving devices.This solution would be improved with the addition of flexible raid volumes.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.

Pricing and Cost Advice
We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired.The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive.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.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.

Many insightful answers already provided.

I would just add the following based on my experience. With so many employees an located in different places, its important for you to list the issues being encountered with the present setup, in addition of the need to upgrade, of course :

- Latency -if being experienced generally or specifically to a location as this may indicate a network issue and this is better solved before the upgrade to new storage in order not to disappoint users

-Type of need : analytics/ Big data, classical operational transactions, archiving - in this case you may go for Tiering ( that is have NVMe as the top Tier and SSD as Tier 2). Users are normally demanding but given the costs in a time of budgetary cuts, better offer them different Tiers with front end ones data residing on the better Tier

- Finally, also make sure you have some well structured storage network as you don't want some big fat slow Database VMs located in one of your data centers impacting on the performance of your leaner VMs provisioned on NVMe.

Hello Robert,
What you need to know is in the world of storage infrastructure all the constructor offers a portfolio group by categories like Entry Level Storage, Midrange Storage, Enterprise storage
PowerMax is an enterprise storage on the DELL EMC portfolio
Enterprise storage is usually used for Mission critical Application where the availability required is 99,9999%. With enterprise storage you can manage approximatively 15Millions of IOPS which are very important when you want to take decision to consolidation storage.
Personally, if you cannot expect to reach Millions of IOPS I recommend to go to DELL EMC Unity XT, otherwise move forward to Power Max
PowerMax offer many features like SLO for categories of Application (Diamond, Gold, Silver)
 Diamond latency < 1ms
 Gold Latency >1ms
 Silver Latency >10ms, <20ms
You have also FastVP to move Hot Data to the fastest TIER storage
Physically PowerMax use a Virtual matrix to interconnect all the Engine which can reach 8 depending of the model
Midrange storage use only two controller and provide you and availability of 99,999%
Unity XT is better than HPE MSA or 3PAR
If you want other informations you can contact me

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